DIY Hydro Power
It’s scenic, it’s rustic, it’s tranquil – and it’s clean, renewable energy. This DIY water wheel was created with many recycled materials and generates about half of the designer’s electrical needs – complementing the output of his solar panels at the New England home. Hydro energy is an old, but not forgotten, sustainable [...]
Imagine the savings on your electric bill – and the environmental benefits – if you no longer depended on fossil fuels to warm your water! This DIY solar water heater is inexpensive to build and provides scalding hot water in just a couple hours. This particular project requires a little scavenging if you want to [...]
Shade of Green: 100-year old pine tree
Items Needed: Stack of 2×4’s, 4 sheets of 2-inch foamular “pink board,” 4 sheets 1/2-inch CDX plywood, enough cedar tongue-in-groove paneling to cover the inside of your framed walls (exactly how much will depend on the size of your “fridge”), 2 small 24v computer fans, 1-3/4-inch hole saw, nails, [...]
This was a very successful project, I used an off the shelf 3 bladed propeller, beautifully balanced and extremely strong, made from glass filled nylon, they are designed as ‘pusher’ props and can spin at up to an amazing 13 000 rpm when driven by a radio control plane engine. I suspect just 1500 rpm [...]
A Chinese farmer has made his own solar-powered water heater out of beer bottles and hosepipes.
“I invented this for my mother. I wanted her to shower comfortably,” says Ma Yanjun, of Qiqiao village, Shaanxi province.
Ma’s invention features 66 beer bottles attached to a board. The bottles are connected to each other so that water flows [...]
MAKING THE GENERATOR
Although you can simply wind the coil directly around the plastic film can (see picture of the first prototype) it is neater and easier to make a simple bobin to wind the coil round. Here’s how to do it:
Step 1
Find a 35mm plastic film can and remove the lid. Cut out two cardboard [...]

The Turgo turbine is an impulse type turbine; water does not change pressure as it moves through the turbine blades. The water’s potential energy is converted to kinetic energy with a nozzle. The high speed water jet is then directed on the turbine blades which deflect and reverse the flow. The resulting impulse spins the [...]
