Get your white coat, your plastic gloves, glasses and turn off the lights… you have just made your first nuclear fusion reactor and you want it to work. At least that’s what instructables.com user Christensent suggests through a DIY posted on the site, aimed at those who want to do some exotic research.
It looks like men are not the only ones who love technology, welding, batteries and electric motors. After presenting the example of Eva HÃƒÆ’€kansson, who plans on building an electric motorcycle, I stumbled upon the story of another girl, Jennifer Holt, from Columbus, Ohio, who built her own electric bike.
Solar water heaters are not a new idea, but people who often complain about rising energy prices should be reminded to use such devices to help heat their homes and take a shower, too.
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.
