Without arguing with your main point that PV is the largest market, I think your statement is not true and unfair to those who do have microhydro potential. Relatively small streams can generate household amounts of power. I built a weir and did a flow test on the seasonal stream behind us, and I estimate it could generate close to 20 kW, November through March. That's 72 Megawatt-hours annually. That's enough for all the electricity needs, including some electric baseboard heat, for over two households -- hardly an amount to neglect! Micro-hydro remains the most economical, trouble-free way for anyone with a stream and 100+ feet of head to obtain electric power. Granted, only a small minority meet those specifications, but I would submit that most of those are undeveloped. :::: Nature has optimized the best way to optimize solar energy for maximum power through photosynthesis. -- Mary Logan :::: Jan Steinman, EcoReality Co-op :::: _______________________________________________ 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)
