Let's not forget the Coalition’s stupidity over the past 9 years: things would have been the same had they been returned. The LNP was only 'an inch to the right' of Labor on this climate scam. Sure, the idiot Albanese is grinning about his increase to a 43% by 2030 reduction in a minor essential gas, but that’s just a feel good figure, which is not going to happen anyway. Whatever bunch of bozos we have to endure, Australia now has an unreliable, third world electricity system. We could be plunged into darkness, unable to work, at any time. Buying solar panels and batteries from the wealthy hustlers who started this crap will make no difference. Short of getting back to coal - which hypocrites like Green Keane are now calling on to save us - Australia is well and truly rooted.
The expectation that people who can't really afford to, are going to cover their roofs in solar panels - provide power for themselves that has always been provided for them, is insane. Our political class is insane. Since the Howard era, Australia has been mishandled by idiots. The Morrison brand of idiots must now be thankful that they lost the election: electricity shortages; rising electricity prices; rising petrol prices; empty supermarket shelves because of those things; inflation that has only just started.

Australians have to accept that we have no friends in Canberra when it come to climate nonsense and reliable energy.
Liberal senator, Sarah Henderson, says, "Of course we support the switch to renewables", and brags about Liberal "record investment in renewables". Posted by ttbn, Friday, 17 June 2022 9:45:32 AM

Agree with most of this< Viv. And before continuing let me add that I have earned a living as a chemical engineer, an assayer, a lab tec, and a science assistant for a power Authority. And have spent the best part of 15 years researching nuclear energy.
But not conventional nuclear energy but unconventional MSR thorium nuclear energy. Thorium is the most energy dense material on the planet and just 8 grams of the mineral would power your house and car for a century without refueling. At a cost of around 1 dollar a year given mining and refining costs for that fraction. Further the super conductor, graphene which is 200 times stronger than steel could be installed as a cling wrap thin layer under roadways and byways to transmit all our reticulated energy to anywhere, making those same roads maintenance free for decades. Given they then would be reinforced with a product 200 times stronger than steel! And given it is also a superconductor, eliminate most of the current transmission and distribution losses that in total are up around 75%. Aside from all that the only renewable worthy of consideration in the mix is solar thermal. And on a huge broad scale. Because it can be so configured to retain useful heat for up to a week and can be sited on virtual wasteland outback not suited to any form of sustainable agribusiness. And compares well with coal in the construction phase and the endless fuel is free and cannot be gamed, particularly if rolled out as a publicly owned and controlled amenity. TBC. Alan B.

Given we progressively roll out under roadway cling wrap thin graphene, we could fit electric vehicles with an underbody magnetic interface battery charging disc that would then allow the magnetic field generated by the transmission of electrical current in the graphene to charge your electric vehicle on the go and make a journey from Melbourne to Darwin and return without refueling, feasible.
An outback solar thermal plant would need economies of scale and the automated production of the polished steel mirrors to compete with the construction of new coal-fired power plants. And given proper routine maintenance could still be powering Australia for a century or two? And a great boost for local green steel production. Solar voltaic comes with the dumping of vast amounts of toxic waste into the environment and mercury the nastiest of them, given it winds up in wild fish stocks and then in the brains of fish eaters, lowering their average IQs by significant margins as the first known deleterious result. Also needs pumped hydro and quite expensive battery backup and triple costs to be halfway reliable. And needs replacing every 25 years to maintain viability. Who knows what that'll cost us 25 years from now? TBC. Alan B. Posted by Alan B., Friday, 17 June 2022 11:45:42 AM

Hydrogen will probably be a fuel of the future and needs cheaper than coal, safer than coal and more reliable than coal, nuclear MSR thorium as the power source, to compete with fossil fuels. Flame free nuclear power alone will allow the production of alternative fuels, plastics and fertilizer from abundant seawater, using known science.
Hydrogen production via electrolysis can be doubled using a catalyst. However, the cheapest form of hydrogen production has to be via the cracking of the water molecule in a closed system using flameless nuclear energy, i.e., MSR thorium. Sadly it seems, not a single Aussie Pollie (pollie want a cracker and given outcomes, probably has a similar sized brain as a shared facility) knows any of the above and as a class, are, I believe, a science free zone!

Sadly most greens Know SFA about nuclear energy and can only parrot the garbage in garbage out, idealogical imperative that drives them? Truly what they actually know about nuclear power could be written on the back of a postage stamp using a crowbar dipped in tar for a pen!
What they don't know is, MSR technology can be tasked with burning nuclear waste where it is just mostly unspent fuel. Providing almost free energy all while reducing the half life to 300 years. Or that the longer the half life the less radioactive the substance is. Bananas are radioactive as are Brazil nuts and milk! Thorium is fertile not fissile and is as the element, less radioactive than a banana! And needs to spend a fortnight in the blanket of a reactor to become fissile, namely as U233. Moreover, thorium becomes the Great, Great Grandaddy of the miracle cancer cure, the alpha particle Bismuth 213. which is attached to a cancer anti body that then targets the death sentence cancer with little perceived damage to the surrounding healthy tissue And has been successful in several European clinical trials on ovarian cancers. I'm also informed that it has been successful in numerous other death sentence cancers including some very nasty and inoperable brain cancers. That the two most environmentally harmful waste products can be sealed in containers in a shielded environment on a production belt, to irradiate cyrovaced food, that will preserve it farm fresh for decades if not centuries, freezer free! That some communities where the background radiation levels double that of the rest have half the cancer related health outcomes. And applies almost equally to general health related outcomes. It seems a little radiation is actually beneficial. That used fuel rods can be sliced wafer thin then covered with manmade diamonds that then convert all the radiation to long term electricity! Imagine never having to ever charge your phone again? TBC. Alan B. Posted by Alan B., Friday, 17 June 2022 12:51:43 PM

Australia is between a rock and a hard place.
The oil companies are making long plans for exiting the oil industry. The mad rush to renewables has faltered, and has every prospect of never meeting the promises of the greenies. Alan shows us a number of look good methods. Thorium from my point of view should be a possible. India I read is building a thorium reactor presumably for power generation, but it has all gone quite. So with a faltering electrical system and a nonoperational solar and wind system, where do we go from here ? It seems that we must refurbish the surviving coal fired stations order a number of gas turbine stations, sack the idiots that blew up the coal fired stations and buy a stock of candles in the meantime. After we catch our breath order a fleet of nuclear stations. I cannot see an alternative to that path as it seems we will be less broke going that way. Posted by Bazz, Friday, 17 June 2022 3:03:53 PM

It is good to see people here who realise what a catastrophic hoax renewable energy is. I keep hoping that the major political parties will realise that the renewable energy Easter Bunny isn't real, but the current energy supply problem seems only to have intensified their stupidity. Obviously Malcolm wasn't the only science moron in parliament.

Indeed Fester, I only hope the first run of blackouts will cause
those pollies that know which way is up will then raise some questions. The real problem is will they ask the right people ? As announced on TV today we are going to introduce 85% renewables, 43% emission reduction all by 2030. Oh yes for icing on the cake, only electric cars by 2030 ! Someone has lost touch with reality !

The article says: "We can have Renewable Energy, or Reliable Energy, but not both."
I disagree. You can have both if you're prepared to spend unimaginable sums on it. I've said before that the people want renewable energy, reliable energy and cheap energy. But you can only have two of the three. Cheap and reliable means no renewables. Renewable and cheap means no reliability etc. Every PM since Howard has floundered on the problem of trying to pretend all three are possible. Despite a new government, getting all three remains impossible at least for now. Turnbull solved the problem of convincing people they could have it all for a while by touting Snowy 2.0. That's now a disaster which doesn't get discussed. (http://www.smh.com.au/national/five-years-on-snowy-2-0-emerges-as-a-10-billion-white-elephant-20220310-p5a3ge.html) As prices continue to escalate, it'll be interesting to see how long the government can hold the line on their emission fantasies.

It's too late to be talking about uranium or Alan's thorium when we now have an energy emergency, thanks to the renewables lunacy. The only way out of it - until we have enough time to build nuclear-powered plants - is to go back to what we have: cheap, abundant coal. For me, it would suffice to go back to coal and stick with it.

"Thorium from my point of view should be a possible. India I read is building a thorium reactor presumably for power generation, but it has all gone quite."
Thorium remains a fantasy. No such reactor has been built apart from an experimental one in the US which failed to produce any power but did produce plenty of toxic waste. The Indians have been promising a proof-of-concept model every year since 2010. Its more of a grant gather than a power solution. China likewise has promised a model in 2020 then 2022 and now no earlier than 2024 with no commercial model available before 2035. Posted by mhaze, Friday, 17 June 2022 5:20:43 PM

Alan B: "I have earned a living as a chemical engineer,..."
Personally, I strongly suspect that you've never studied engineering at uni. The mere fact that you can't even get the units for energy right (though you've been corrected numerous times over the years) indicates that you've probably never even studied science at the senior high-school level, let alone studied something as advanced and challenging as engineering at uni. Perhaps you could provide to doubters like myself some proof to your claim that you've been a chemical engineer. By-the-way, if you really were an engineer then you will most likely be aware that engineering is a profession that requires mandatory registration. Claiming to be a qualified engineer and giving advice when not registered can land you in court facing charges. The minimum mandatory requirement is successful completion of qualifications compliant with the Washington accord* and to be registered. (This is similar to how doctors can't practise medicine without the necessary qualifications and being registered.) *: the Washington Accord is an international agreement on accreditation for tertiary level education courses (usually at least a degree) dealing with engineering.

That's a bit mean, thinkabit. I don't like phoneys either, especially this creep:
https://www.smh.com.au/world/fake-engineer-and-a-deadly-building-20120914-25xpd.html I wouldn't think anyone here would come within cooee of the likes of that fellow. What concerns me more are all the qualified engineers presiding over the transformation of Eastern Australia's power supply into a pig's dinner, all for the sake of being woke. Will that get any of those clowns charged or de-registered? I suspect that the coalition thought they could go along with all the renewable energy bs in the hope that smrs would come to the rescue.

I earned a living as a chemical engineer. That I was self taught, didn't matter to management who claimed I was the best that they had had/presided over a turnaround that took a nearly bankrupt company on the brink of closure to one recording three years of record profits and production.
As for units I see nothing wrong with KWPH. Nothing wrong with being self taught. Not too bad for a kid that didn't complete a single year of high school! No school or uni. or degree can increase your IQ, just the, toffey nosed snobiness, that comes with privilege! Go do fifteen years of research, yours, before you rubbish the work and contribution of others! You pain in the ass, cyber bully! As for Oakridge and the toxic waste The funding was pulled before the reprocessing could run its full course, so naturally there had to be waste and burial, dug up to provide miracle cancer cure, bismuth 213. I bet none of those casting aspersions have done little more than five minutes study on thorium, probably via some bogas St Petersburg, link? Thorium was abandoned in the fifties/seventies due to the extreme difficulty of weaponizing it! And it would have put the fossil fuel industry/big nuclear out of business as well as seriously downsizing big pharma's profits! All lined up to shout it down and fight like hell in congress, until recently, to avoid its consideration ever. Now on the table in the US, not here due to hidebound politics Today during the energy crisis/engineered scarcity, thorium must be considered/on the table along with the mass production of the reactors, which under the right management/production model, could be rolled out at one a day! As for the coal/gas "market", it costs us as much in real terms as it did a month ago in AUSD to mine our coal/gas from our ground. The only problem is the, greed is good, price gouging by the foreigners now in control thanks to moronic decisions by "brain dead" Aussie pollies. Alan B.

Alan,
If thorium molten salt reactors became a reality, it would be easier to make nuclear weapons with them than with conventional reactors. The reason for this is that an msr would require continuous fuel processing to keep the reaction going. By such a method it might be possible to remove protactinium generated by the reactor, which would quickly decay to U233, from which you could make bombs. https://thebulletin.org/2018/08/thorium-power-has-a-protactinium-problem/ With fuel rods and pebbles you can have international regulation of fuel reprocessing, making the production of nuclear weapons less likely.

Alan B: "I earned a living as a chemical engineer." - *NO* you didn't unless you were breaking the law (or unless you're really old and worked before the days that calling yourself a professional engineer required registration). It is a statutory requirement that you MUST have the necessary qualifications to practice as an engineer. You *may* have earned your living as someone who did some of the things that a chemical engineer does- but without registration then you legally *weren't* a practicing chemical engineer.
"As for units I see nothing wrong with KWPH." - well it doesn't surprise me that you don't and that's because you (by your own admission) lack a formal education. The units of energy when expressed in kilowatt hours in standard form are: kWh (there's usually dot between the "kW" and "h" but I couldn't be both typing it) - http://en.wikipedia.org/wiki/Kilowatt-hour. Over the years you've written all sorts of variations of this- from memory sometimes KWHR, KW/H, etc. And even though this has been explained to you more than once previously you to still (as of this morning for example) write it wrong! Getting your units correct (and more generally proper use of common technical terms like stain, stress, force, field, work, energy, etc.) is a shibboleth for people educated in scientific fields. Correct v's incorrect usage is one of the best/fastest ways to see if someone actually knows what they're talking about. Understanding units and measurement is so important that students of science/engineering typically do a lectures devoted specifically to this. Dimensional analysis is a very cheap/fast check that your calculations/equations are not "not even wrong"- http://en.wikipedia.org/wiki/Dimensional_analysis and http://en.wikipedia.org/wiki/Not_even_wrong . -- continued below -- Posted by thinkabit, Saturday, 18 June 2022 3:07:05 PM

"... a kid that didn't complete a single year of high school!" - yep this claim I can easily believe, it is blatantly obvious from your posts. In fact I reckon just about anybody that does have half a clue about STEM subjects would come to the conclusion that you've never studied high school science/math subjects formally. By-the-way: I've never said that a degree will necessarily increase your IQ. A person's potential IQ is set at at conception- some people are born smarter than others due to genetics. However for a person to reach the maximum of their IQ potential they require raising with mental stimulus and in a healthy environment (eg: where a healthy environment is good food, low toxins, low stress, proper sleep, etc). But having a high IQ doesn't mean that you're knowledgeable in STEM fields. However, obtaining a STEM degree is an exceptionally accurate indicator that you've a higher than average IQ (especially if it's a pure maths degree).

thinkabit,
Actually mandatory registration for engineers is quite a new thing. IIRC only Victoria requires it at the moment, though Queensland will soon. ____________________________________________________________________________ Alan B., > I see nothing wrong with KWPH It's a rather messy way of putting it (it would be much neater to write kW/h) but the unit itself is a perfectly reasonable way to measure the increase in power production (or indeed the increase in demand). Personally I'd prefer to use the SI unit (W/s) but theres nothing actually wrong witnessing other units. However I hope you agree that there's everything wrong with conflating KWPH with kWh. BTW superconductivity in graphene only occurs in certain very hard to achieve circumstances. Posted by Aidan, Saturday, 18 June 2022 5:03:56 PM

Sorry, just noticed I've just noticed my typo/autocorrect error:
"witnessing" should be "with using". _______________________________________________________________________ mhaze, Where d you get the idea that "cheap and reliable means no renewables"? SA's power supply is far more reliable than it was when the state had no renewables - indeed since we got the first big battery it's been the most reliable in the nation. And the ACT, with contracts for renewables to supply all its electricity, has the cheapest electricity in the nation. Posted by Aidan, Saturday, 18 June 2022 7:38:40 PM

Aidan
According to some info presented by ttbn, wind and solar provided less than 2% of Australia's power the other day. Less than 2%! On what basis do you claim it to be cheap and reliable? Europe is not having an easy time trying to go carbon free with wind and solar. Nuclear power can provide low carbon energy for a third the cost of wind and solar, as France is demonstrating, yet it is off the table. If humanity faces a catastrophe then why should any potential solution be off the table? Posted by Fester, Saturday, 18 June 2022 8:24:00 PM

Protactinium decays to Bismuth 213. Thorium spends around two weeks in the blanket of a conventional reactor to become U233. KWPH is how the yanks express kilowatts per hour and as I do.
Removing Liquid U233 from a MSR to make a bomb is extremely difficult and those who tried recently in Russia all paid for it with their lives due to the lethal mega-radiation they were exposed to! Did the wright brothers qualify as flight engineers? Not one single pioneer in any field that was new had a formal education that discipline as a rule of thumb. The inventor and patent holder of the first working nuclear reactor was a Chemical engineer. A degree does not mean very much given the cramming that precedes exams and the knowledge crammed soon forgotten. A chemist is only as good as his reference text book library. Original thinking is not conferred by a degree. I studied medicine and qualified with honours and an average passing mark 98% that broke a seventy year old record. Yes, it was as just a medic and conferred just a certificate. And surprised the number of young recently qualified doctors in that room. I've always used and understand KWPH or PKWH! And I stand by my comments about thorium as the way of the future, given thorium delivers everything fusion promised but never delivered. People who critigue me are not concerned or my lack of formal education but just getting any expectation of any serious consideration of 1 cent PKWH thorium off of the table! The bugs, corrosion and tritium have been ironed out, the first by adding a layer of carbon to the metal reactor surfaces and tritium is absorbed by the use of nitrate salts in the heat exchange cycle. The 5% waste that comes with MSR technology is still useable as long life space batteries and becomes stable in around 30 years. Thinkabit, rules are for fools! And stay in your box where you do all your thinking!? Y'all have a nice day now y'hear. Alan B. Posted by Alan B., Sunday, 19 June 2022 11:39:45 AM

Alan,
Protactinium 233 is produced in msrs and decays to U233 with a half life of around a month. Just because some Russian scientists failed to isolate it does not mean it isn't possible. A functional msr has lots of potential benefits as you regularly point out, but the problem is that you have onsite fuel processing which opens the possibility of using msrs to produce nuclear weapons. Pebble bed reactors offer the prospect of continuous operation over long periods without such risk. I'd like to see msrs developed, but I would not think it safe for them to be widely used, certainly not with the way the world is at present. Posted by Fester, Sunday, 19 June 2022 1:13:10 PM

Bazz,
Not if you use some of the tidal flow to pump water into storage ponds to use between tides. Posted by Is Mise, Sunday, 19 June 2022 3:02:18 PM

hmm, AlanB is now using "PKWH" units which in SI units would be Peta-Kelvin-Watt-Henries.
Ahh, Uh-huh, it's all making sense now! This is obviously the unit for some exotic temperature-power-inductance figure that results from some complicated calculations AlanB has done regarding his graphene road initiative for recharging EV's via magnetic inductive coupling while they drive along it. Evidently he's invented/produced this new composite graphene material that he can mass produce for next to no cost. And he's derived this you-beaut equation that relates this new material's super-conductivity's sensitivity to heat, the maximum electric power through-put it can sustain and its magnetic inductance when used to wirelessly transfer energy (this is where his PKWH units come into play). This equation unequivocally shows that his recharging road scheme is all perfectly feasible and will save the world from all sorts of vice once implemented in combination with his Thorium reactors. And Oh boy, those Thorium reactors are amazing! For example, years ago when Alan started extolling the virtues of his reactors the projected energy cost was 0.02$/kWh* (if i remember rightly) and these days it's 0.01$/kWh. They're a goddamn inflation resistant economic miracle: that's a 50% decrease in cost due to his program of technological progress and continually improving efficiencies over the years- and this was achieved without anyone ever building one! See like I said, they're absolutely amazing- can't wait till someone forms a company to actually build one. [*: Since AlanB writes any unit he feels to represent any quantity he wants I'll write "$" units for money the way I prefer- ie: suffix not prefix. :) ] -- continued below -- Posted by thinkabit, Sunday, 19 June 2022 3:48:31 PM

Oh, by-the-way, AlanB I will "stay in your box where you do all your thinking", because the box where I do my thinking in is called "The Scientific Method And Its Results". I love being in this box so much that I hardly ever get of it- it basically forms the hard boundaries of what I think about and how I think about things. And it's a very, very big box full of all sorts of wonderful things to play with and think about. For example, in this box you will find glorious stuff like: physics, chemistry, biology, geology, etc. Perhaps one day you might jump into this box and think about/play with these things too? Since after you do that then you will no longer need display your complete ignorance of this box's contents in your posts. Posted by thinkabit, Sunday, 19 June 2022 3:50:51 PM

"can't wait till someone forms a company to actually build one"
China was supposed to start testing a prototype in September last year. https://spectrum.ieee.org/china-closing-in-on-thorium-nuclear-reactor I note in the comments from the article: " Significantly, neither the historic ORNL MSRE reactor nor the proposed Kairos reactor use Thorium as fuel, which appears to be the chief breakthrough of China's MSR design. I suspect that China's MSR design may be less constrained by regulatory agencies than MSR designs from other nations, which are strictly forbidden from use of design features that might conceivably be exploited for weapons proliferation purposes. The primary example of such a feature is continuous online chemical separation of the fertile isotope Pa233 as an intermediate by-product of breeding fertile Th232 into fissile U233 . The continuous online separation of Pa233 is said to be necessary in order to prevent accumulated Pa233 from absorbing so many free neutrons that the ongoing U233 fission chain reaction [presumably thermal] grinds to a halt while waiting for the Pa233 to beta-decay into fissile U233. [3]. If breeder-generated Pa233 were separated, diverted, and removed from the reactor, the eventual result would be ready-made weapons-grade U233. China may have a unique reactor security regimen that protects this material from clandestine diversion or they maysimply choose to ignore it. Or their technology may have an undisclosed feature that solves the Thorium breeding problem without creating a weapons proliferation problem." Posted by Fester, Sunday, 19 June 2022 4:02:47 PM

Fester, why would anyone make a bomb using liquid highly radioactive U233. The world already has enough uranium or plutonium bombs to blow us all to kingdom come three times over.
The reactors I would prefer are mass produced SMR's that only ever have a very small amount of radioactive material in the core at any one time. And placed where we have transformer hubs now. So those oil filled things need not be ever needed? And burn when overload kicks in? As SMRs that never ever enough material to reach the critical mass that one needs to create a thermal nuclear device And buried underground in tunnels that could be weaponized with movement activated claymores. That don't activate unless the intruder doesn't have the right iris/fingerprint/DNA/normal body temp., etc. That MSRs are walk away safe and run for literal months without humans monitoring the self regulating reaction, means the security can be as tight as! Graphene is mined as mineral that comes as the mineral in the deposit or as an associated mineral in iron ore. Just northwest of Sydney is a large, almost pure, commercial deposit. And I don't know if it is temperate sensitive like thorium which is also a super conductor when very cold! Gas can be made as unlimited biogas. Every Australian family produces enough organic material that in a locally invented two tank fermentation smell free, closed cycle system, will produce enough methane to power their domiciles and forever! The addition of food scraps creates a modest salable surplus. The addition of a scrubber and a ceramic fuel cell more than doubles the salable surplus as more than 50%! So, with this included in all new builds, and added as a makeover in older builds, we could not only never ever run out of gas but put local green steel production on steroids. Ditto very broad scale solar thermal! The trick will be to keep all of this in Australian hands as family/public/Aussie co-ops ownership To limit the opportunities for price gouging by tax avoiding, profit repatriating foreigners!

use some of the tidal flow to pump water
is Mise, In theory, tidal power looks attractive & viable. In practice it is near impossible due to marine growth. There have been quite a number of experiments all over the planet & I'm not informed sufficiently to say if any of them are actually producing power on a commercial scale. You just need to visit a dry dock or any slipway to get the idea of the immense effort to remove marine growth from the flat surface of ship hulls. Try to imagine clearing such growth from the complexity of propeller vanes, piping, cables etc. Imagine trying to dry-dock such infrastructure & the environmental aspect of such cleaning processes. You'd not find sufficient spare power to pump large enough amounts of water to aid in the turning of turbines. Anyone familiar with but hasn't studied such technology will tell you that today's technology hasn't reached a point as yet to make such schemes viable. Neap tides alone would pose a big problem.

Alan,
I like the concept of the thorium msr, but I suspect it might have trouble getting approval from the IAEA, so if the Chinese prototype works it will be interesting to see what happens in that regard. I do like your take on biogas, and I suspect that it will gain more prominence in coming years. Is Mise, Nuclear power certainly needs good maintenance as the French are finding out. I'm guessing that some years ago they thought they might replace their reactors with solar panels and windmills. Not good timing.

Yes Fester, you're probably right. And because our price gouged energy is owned or controlled by foreign interests, who don't want a bar of carbon-free MSR thorium and own the pollies?
I understand near neighbour Indonesia, is buying or has bought one. That some Scandinavian firm built in a doubled hulled barge and towed to whatever site deemed suitable. The difference, Indonesia hasn't sold its sovereign independence to any with the money, like whore Australia. Simply put, if we don't buy or build some SMR, MSR thorium and get the cost of energy way down! Our economy will all but die under the load we will have to carry! Renewables won't save us but put a unrepayable yoke of debt around our necks due to the cost of batteries pumped hydro etc., that we will need just to keep the lights on let alone make green steel or aluminum, or anything that is high tech and energy dependent! I think if we go down that path our Great, Great Grandkids will still be paying interest on the never ever debt! One doesn't need a degree to understand that or read a book! Alan B.
