# The microhydro plant

My little paradise has a stream that provides enough water flow and head to run a small turbine, to provide electricity to my home. While writing this, the microhydro plant is being implemented, and here are some photos of the process. Since I usually like to start at the end, the first thing I built is the controller: It is an implementation of Jan Portegijs' "Humming Bird", with some changes and adaptations. The largest cost of the plant, by far, is in the piping for the rather long penstock. When the purchase was made and the truck arrived, we unloaded the pipes at different places, to get them as close to the installation area as possible. A smaller number of pipes were stored closer to the turbine site. Only for the last part of the run, where the pressure exceeds 2 bar, I will use blue class 4 PVC pipe. To change from the low slope run of the white pipe to the much steeper run of the blue one, a change of direction is required. The flat area is where the forebay will be built. News!

DIY Residential Wind Generators DIY Wind Generators I made two wind generators, one was a motor from a stair master and one was from a tread mill. The third wind generator I bought. It’s rated for 1000 watts per hour at 22.3 MPH. Solar Panel Testing Shunt Regulator I designed the Solar Panel Testing Shunt Regulator to function as a variable voltage shunt regulator for measuring the power output of small solar panels. I wanted to be able to load the output of a solar panel with a variable load to obtain various output voltage levels and measure the corresponding current flow. Repeating current measurements at various voltage levels to characterize a solar panel without having the output voltage level drift.

Pump Water Without Electricity - energy of flowing water (Before It's News) A water wheel uses the energy of flowing water to move the water through coiled pipe and as it spins it continues adding water through the coils. Depending upon where you set the output pipes you can move water from a creek to your field without electricity. New device generates electricity from condensation MIT researchers have found a way to generate small amounts of electricity from condensation, by having electrically-charged droplets jump between superhydrophobic (water-repelling) and hydrophilic (water-attracting) metal plates. The advance could be especially useful in remote areas or developing countries, not least because it produces clean water as a side product. While pulling electricity out of thin air is a physical impossibility, producing it from water droplets in the atmosphere is very much within our reach.
