Got this PM from someone well known and respected on this board:
The biggest problem with them is economics. The payback period for the investment is still quite long. To make a house energy neutral you might spend an extra $30K - and that won't get recovered short of about 12-15 years last time I saw hard data.
The older systems simply heated water, while the more modern systems actually generate power.
And its not the oil companies' fault. The people that can afford to do it need to, so that it drives the price down for everyone.
