Give anybody a choice between two systems, each of which keeps the lights on whenever you flip the switch, one with a total lifetime cost of $10,000 that only has 10% energy efficiency and the other with a total lifetime cost of $100,000 and 100% energy efficiency, and basically everybody is going to be all over the inefficient system. Sunlight is the cheapest thing there is anywhere within a billion miles or so. What do I care how much of it I waste? PV capacity is less cheap. I'm probably going to care if I need to put twice as many panels on my roof, but it's not something to dismiss out of hand. Any more, the panels themselves aren't that significant a percentage of the cost of the entire system. Batteries are expensive. I'm definitely going to care if I have to throw them all away and replace them every few years. b& _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
