It seems you are afraid of losing money. I have no problems with paying taxes. I don't rip anybody, I'm just experimenting with generating electricity, Every few months I buy a part. No taxpayer payed for my investment. In fact, I pay tax for the parts I bought, so you should be happy! I 'm living the alternative way, just staying alive. I use about 2000KW a year, just because my computer consumes to much. I'm trying to reduce my energy needs to 1000KW a year, hope to get there in 2012. -- Ik praat liever tegen een domoor, dan tegen dovemansoren.

They don't seem to have got around to blowing up the long vulnerable natural gas pipes between Russian and Europe yet. Maybe they can be made less vulnerable than they look. -- Bill Sloman, Nijmegen

YOU are the one pushing solar,YOU be the one to spend YOUR money and show us how it works. document your costs,savings and how often your system is not providing any usable energy. -- Jim Yanik jyanik at localnet dot com

If its so beneficial,then everyone in the building would join. BTW,trying to generate practical,useful quantities of methane gas in a residential building might be a hazard to other occupants.(explosions) It might even be a nuisance.(odors) -- Jim Yanik jyanik at localnet dot com

That's always the problem, isn't it? That reminds me of the great Alfred E Newman quote: "Two can live as cheaply as one, it just costs twice as much." John |
