Bazz- Thanks for the feedback. They use Geothermal in NZ and apparently supplies 13% of their power.

I found a link...
http://www.oit.edu/docs/default-source/geoheat-center-documents/quarterly-bulletin/vol-19/19-3/19-3-art1.pdf?sfvrsn=4

Bazz said- "Tidal, another source demanding storage twice a day."

Answer- Are you saying the cost of building managing a dam/ pipeline as a power storage facility makes the energy too costly? I'm aware that energy storage is the major problem. I've also come across molten salt storage (800 degrees) in my reading- the same as thorium reactors use for heat transfer- wouldn't be as big an engineering problem as building a dam I guess- still fairly experimental and low density but this isn't as much a problem in a fixed power facility.

Loudmouth- Thanks for your feedback. I found brain surgery more interesting than your description. But basically sounds right. Not that I'm an expert. As I understand the brain slides as the scalpel cuts. I'm sure there is a fair bit of risk analysis to avoid critical areas and it takes much experience and knowledge to get it right. There was some excellent programs on late at night with a surgeon that did an unusual dissection of the digestive system from the back. Rocket Science is also an interesting area- I once used a spreadsheet and the Tsiolkovsky rocket equation to maximize rocket altitude. :P

Seriously- I viewed Geothermal as essentially a simple "steam engine" but I'm not an expert on Geothermal systems so I didn't know (I should have guessed) about the corrosion. I have a fair understanding about engineering for a lay person. Are you aware of any other issues with Geothermal systems such as those used in NZ and whether there are additional issues with "deep" systems?

Sorry Canem Malum there are problems with both of those.

With Geothermal systems without a highly volcanically active area, the rocks even in hot spots, cooled too quickly to be of any use. It took most of the power generated to drill new holes to find more heat. Perhaps with horizontal drilling & fracking it may be more successful, but currently simply not productive enough long term.

Opps I used that dirty word, fracking.

No one has ever made tidal really work. Ask the Spaniards, they spent a fortune trying. They also spent another fortune trying to make wave action work. After all they have the Bay of Biscay, which is pretty wavy, but all they got was rusty scrap metal.

I KNOW! Lets try thermal COAL. That is even proven to be the cheapest way of generating electricity, so let's not try to reinvent the wheel.

With all the research coming out right now, 168 peer reviewed papers so far published this year, showing that our climate is controlled by the suns magnetic field, & the solar wind, it is about time we put the scam of CO2 to bed, & get back to some real science

Canem, geothermal in NZ is different as they have it close to
surface, ring of fire etc.
In Australia that does not exist, the way it was tried was to drill
down into the granite, don't remember how deep it was thousands of feet.
They then drill another pipe down somewhat separated and put water
down one and get steam out the other.
The granite is heated by radio activity, The government put some money
into it but all I heard was that it failed because of corrosion.

Storage complicates the system and adds very significant cost.
Far better batteries that we are always hearing are like fusion just
about to arrive.
I suspect batteries have reached that technical improvement point
where any improvement will only be at the margins.
The reason for batteries etc is to compensate for wx difficulties.
If the same wx conditions happen on the next day the battery capacity
has to be doubled. If the same wx condition happen the third day--

Np one ever considers how big the battery has to get if you get a
string of days with overcast sun and little wind.
Recently Sth Aus went for four days that I noticed with wind output
between zero and 200 Mwatt. Pathetic !

It's official, we have a new 'dumbest idea in the country's
http://www.news.com.au/finance/business/retail/mcdonalds-move-to-ban-plastic-straws-angers-aussies/news-story/45bdb9d7b7144891cc7fadfd033c6e20

Why am I mentioning it?

Does anyone not comprehend the country is being dismantled by socialists?

- And we're asking if manufacturing is coming back are you all insane? -

Don't you all realise the horse has bolted, lunatics run the asylum now.

Socialists, who believe that a social revolution must occur to destroy capitalism and bring in theirs and elites New World Order plans.

It's not like we have 2 parties that both work together hand in hand to bring up the best policies and future, what we have is one lot that deliberately wants to destroy everything and grind the country to a halt to force globalism on us, and our leaders are bloody collaborators in doing so.

You people better wake up from la la land.
The futures not pretty.

AC- OVerall excellent comment. But I'd add the globalists (Aust Libs, Business Lobby) are working with them for their own reasons.
