Needless to say: Electricity over IP – the solution

This morning I found A GREAT RFC, the 3251.

RFC 3251 - Electricity over IP

http://www.ietf.org/rfc/rfc3251.txt

http://www.faqs.org/rfcs/rfc3251.html

I think this may be the solution. 
Unfortunately, it was one of the best kept secrets. Let's make it public available!

Micro Hydro Power

LV 1500 is a very small and efficient hydro power generator (max. power 1500W) made by Hydro Induction Power, a company based in Redway, CA http://www.homehydro.com/.

The LV1500 re are 12V / 24V / 48V models build around a stainless steel Turgo runner, a brushless alternator and a rectifier.

Impressive is the that it works with 60 to 600 feet Head range and 5 to 100gpm Flow range.

For a greater energy need ( max. 4KW) they offer also another product range here: http://hipowerhydro.com/
