dont bother with a UPS for a computer.
THey are only designed to run for 8 min. or so. Just long enough to shut down programs and such. Your better off getting a couple car batteries with an inverter/charge controller and do your own UPS that will last longer...
I think a computer transformer draws 300 watts or so. Your UPS will power that for 8 minutes.... Figure your flourescent lights draw 20 watts for one NO bulb, your powerhead draws 20-50 for a small one. Your still only looking at under an hour of power....
As for your renewable energy ideas, that is my favorite solution.... I am a big fan of alternate energy. I know quite a bit about it and i have done some looking. I have also seen a bunch of installations. For FL, The way to go would be Photovoltaics. I live up in NY and i worked on a house where the guy put in 2 10'x11' solar panels, he can generate almost 2000 watts continuous on a bright day. Imagine what you could do in FL with wide open flats... :cheer: :jumping:
Put that into an inverter with a battery bank of ~20 12 volt deep cycle marine batteries and you could be self sufficient for a few days or up to a week with no power. (conserving power usage of course) Wind, if your near the coast is also a great idea. I dont know how strong your winds are consistantly, but most turbines can start at only 5-7 mph of wind. THey have the potential to generate alot of energy for you.... I know up here in NY the state research association (NYSERTA) gives tax breaks and installation grants for alternative energy systems. That system i was talknig about was around 22,000$, nyserta paid over half and the guy only paid $10,000 for the whole installation.
Sorry for the wayyyy off topic and long post but i kinda got on a rant there.... If you want to continue the convo. feel free to email me.
