Martin,

I'll add another disturbing comment relating in part to the media and to MacKay's excellent book.

I was nuisance called by a PV system sales person yesterday after waffling on about the "ecosystem" and how much I was going to do to help if I invested in his company's product. I asked him how much electricity his proposed 0.9kW array was going produce every day. I asked him guess. I also mentioned that the normal daily demand is around 20kWh and more (mine is 5). He had no idea whatsoever what I was talking about.

This is all quite simple boys and girls. The politicians want more of our money so they need a new tax and have worked out that air (Carbon tax) and Water (Increased water pricing as its a government monopoly) will do the trick.
We need to hack into them at every opportunity keep harping on about fringe benefits tax being charged to the recipient which means Public servants and politicians and ex politicians. Also means test all government pensions for the same people and see how they like that!

There’s one thing we can’t do and that’s to keep on expecting the planet’s to increase its capacity to provide non renewable resources and process an increasing quantity of pollutant. We also are exploiting vital renewable resources beyond the ability of nature to replenish. The result of the present economical system will be catastrophic and could end life on earth according to James Hanson.
I’m afraid, Martin Nicholson’ article is back to front, therefore its worst than useless.
