The next video shows a Stirling engine while working to achieve its best, powered by a 70W light bulb. The poster also shows how he measured various parameters of the engine, like speed, torque, input/output power.
A very neat experiment that anyone with some skills can do in the garage or kitchen is creating a solar cell out of blackberry juice and titanium dioxide (and several other components).
If you want to produce electricity using a river near your home, the best way you can do it is to build a small-scale hydroelectric generator. Often called as a low-impact hydro, micro-hydro or run-of-stream hydro generator, this system is not very hard to build.
Ryszard says it’s much more efficient to assemble solar cell this way than put them directly into light, where you’ll lose a lot through reflection back into the environment. Some recently invented anti-reflective coatings may even accelerate the light’s absorption into the solar cells. This is one of the advantages.
Pinwheels have been used for many things along history. One of the most interesting uses I’ve ever seen is making a pinwheel act as a free energy generator, powered by gravity.
The construction of this universal solar charger is very simple and cheap(only $50) . You don’t need to have any familiarity with electronics or prior circuit knowledge. It can be used to charge any device via USB.
A lot of people want to be green in using energy but they don’t know where to start, or they don’t have enough money/time at their disposal to actually start making something useful.
Something truly amazing comes from Turkey: some students from Sakarya University just released a prototype of what seems to be a car …
The Holy Grail of energy has been, is, and will be the solar power. Numerous solutions of converting solar power have existed along the centuries, and people have always used the Sun to power things up, except for the last hundred years or so – that’s the main reason we all got into troubles with mother nature.
What can you do with a steam powered engine, a LEGO toy kit, some wood sticks and a USB cable?
One simple way of making hot water has been perfected by a blogger on thesietch.org, and it relies on a simple and easy to find piece of junk: an old refrigerator!
Electric motors have simple designs, are easy to operate and have a great resistance to various environments. That’s why they are to be chosen as alternative to internal combustion engines. This is a trivial experiment showing how you can feel you made a real electric motor yourself. Just for fun.
Doyle Doss, a Northern California Inventor, has created a candle powered space heater. It sounds like science fiction, but it really is a simple and green energy device, that could save you a lot of money by only lighting a candle, in the long run. The CO2 output of a candle is too small to mention, and the materials that this device is made of are all here since the Earth exists.
In this consumerism ruled times, the world needs to know ways to do stuff. When electricity generation is predicted to become more expensive (it’s like they predict an invasion of electric vehicles), people need to build their own power generating systems for their independence.
This is about how to build a solar furnace out of a satellite antenna dish and mirror broken in many pieces. As you may know, satellite dishes have a focal point (that is a point in which the electromagnetic energy focuses at its maximum power).
