A little more RE: Greenhouse gas production by hydro dams. I followed up on the "A rather balanced view..." that appeared here recently and which was largely...
Hi Joseph, Send me your contact details (email, phone) and I'll get in touch with you to talk about a few village electrification projects we have happening in...
I am setting up my micro hydro system. Until I get the generator installed at the waterfall and the transmission line in place I am using petrol generators to...
Dear Joseph, We the Center for Energy Studies (CES)of Institute of Engineering, Tribhuvan University often coduct training on Micro Hydro Power as well as...
Hi. Try http://www.pressure-drop.com Software to calculate pressuredrop for all kinds of fluids, pipes, fittings, nozzles, etc. You can test it for 4 weeks...
Chris, Good research! I always enjoy the results where someone diligently investigates and posts the results. That's so much better than a meaningless "Me,...
Graeme, Consider the difference between volt-amps that express complex power in which generators are rated. Driving a resistive load, it will supply the same...
Hello, I use this software, (in french) calculroue Download it at : http://clients.newel.net/particulier/amader/ You can calculate head loss with diametre,...
I agree with Graeme regarding the hash the switched-mode/pwm power supplies make of many generator outputs. The caps are a appropriate solution to the problem....
Hi im located in NJ and looking for some one near by that is running cross flow system, we currenty hoave a location in VA with a old water wheel 14ft by 4 ft,...
Depending on the power you would like to harvest , the cross flow may be not be a good solution. 10 feet= 3 meters 1200 cfs= 34 M^3/s may give about 600 KW. ...

Assuming its HDPE (polyethylene) Warm up the rolls inside overnight. Move it quickly to a spot near the installation. Secure one end and roll (downhill if...
I don't think this is a power factor problem. My guess is that that the generator is "seeing" some of the switching as on-off, particularly at the lower power...
Bowen, If possible work when the sun is shining, anchor one end of the pipe, unroll the pipe and anchor that end so the pipe is stretched out. Let it sit for...

Call eight friends, 4 who pull the end of the pipe and 4 who help unroll the pipe. Finish by a good dinner with good Ardeche (South French) wine That the way i...
Hello, I think like Frank There is a power factor problem I has this problem with fluorecents lamps. Most of petrols generator use bruschless alternator with...
Hi We have just unrolled 17 rolls of 63mm pipe and 1 roll of 100m 63mm pipe (PN16) in the bush for a project. There is no easy way for this in these ...
Hi We recently installed a 3kW invertor and connected to a switchboard with a main switch, then RCD (Residual Current Device) and outgoing Circuit breakers....
NOT enough information !! The 3 KW inverter sine wave or MSW; The RCD or GFI may easily trip if the inverter is MSW-- remember that just 30 milliamps are...

Tks for the replies; I obviously need to provide some more specific info concerning my request. We have a Xantrex Trace 1012 UR-UPS inverter (1000w) and 4 6v...
Allow me to suggest a $30 purchase of a Kill-O-Watt meter. You can then measure the power factor of the washing machine, for example. Normally, a huge power...
