First of all I think the the reference to 500W turbines was meant for the fellow in case he wanted to build a working demo in in backyard, and not Hoover Dam, and secondly 500W is 0.67HP, so that's pretty close.
I'm baffled we're still talking about this. The poster made it sound like it was orders of magnitude off.
Hero and Arrowhead were complaining about 500W turbines versus Gigawatt hydroelectric plants. Then comes a statement out of nowhere that 500W isn't even close to 1HP, which isn't even relevant. In any case, compared to the previous comparisons between 500W turbines and 1GW turbines, 500W is pretty close to 750W. Period.
Thats a top one Bill and maybe a good sign for any member to abort this bullshyte of a thread. The way this Alternate Energy energy forum is going we might aswell just name it Alternate Chat....
If the original OP ever bothered to look at the sticky there is plenty of DIY hydro projects and a few facts concerning loss's etc..
Anyway time to crack another VB asit's 'beer'o'clock' and this thread is really getting up my goat....
Think crystal radio set. I used to collect a lot of stray energy to power that little high-impedance crystal earplug. If broadcast radio goes the way of broadcast TV, there goes my source of truly "free" entertainment.
