$11,111 per home?
If this puppy can keep this up for enough years, it could break even.
The problem is that it can't power any homes at night, so it is mostly useful for 1/2 the year (at most) that A/C needs coincide with power generation. The rest of the time the power is not created at peak time (evening) therefore it is simply not needed since a conventional boiler can't be turned off every day and turned back on at night.
That sounds reasonable. Actually the figure was 140,000 homes, not 144,000, but that is still under $11,500. I know people who are spending $20 and $30,000 to put solar on their roofs, so this seems possible.
