Yet another cool invention from Samsung. After they did break many European and American markets, they plan to knock out those solar power fanatics, by using water as a power source. Yes, you heard right. They intend to make fuel cell batteries that can power anything you can use in your pocket (cell phone, radio, [...]

QuantumSphere Inc. says it has perfected the manufacture of highly reactive catalytic nanoparticle coatings that could up the efficiency of electrolysis, the technique that generates hydrogen from water. Moreover, the coatings could also eliminate the need for expensive metals like platinum in hydrogen fuel cells.
The coatings can be used to retrofit existing electrolysers to increase [...]

Most moth eyes are made up of adjacent hexagonal sectors. Each sector is filled with thousands of orderly rows of miniscule bumps, or nipple-like protrusions. Though formed so perfectly they appear almost manufactured, each protrusion measures less than 300 nanometers, or 300 billionths of a meter - a size that renders them invisible to [...]

BSWT is a vertical wind turbine based on sailing engineering. The wind rotor is rotated by two spiral-formed vanes. For best performance, these vanes are covered in solar cells, so that sun and wind produce electricity as one element. The BSWT installation costs relatively little, produces no noise or significant shadowing, can be easily maintained [...]

 I found out the ingenuity of some people exceeds “common sense” and their inventions are really helpful to humanity. Not on large scale, but for those tech-guys who do nothing but sit all day long in their garages and invent crazy things nobody would have imagined. Most of these inventions stay there, in the respective [...]

Have your ever seen those self-powered mechanical watches, those who charge themselves from your hand’s movement? They have one half of a heavier metal disc spinning around an axis. That movement rotates some wheels, who finally rotate the watch spring.
However, that is not our article’s subject. Our article talks about some newer discovery: some US [...]

Sudia Design Labs, located in New York, has created a table that you can put out in the sun. What for? To charge it, of course! It has a big solar panel on top of it, is made 90% from recyclable materials and weights 20kg. You can charge your laptop, small appliances, etc. Its 64 [...]

Don’t you know? I didn’t either. But the idea is not at all complicated. It’s a lead acid battery combined with a supercapacitor. A supercapacitor is simply a capacitor that can achieve greater states of charge and can output a greater quantity of energy in a shorter time. Power=Energy/Time. The shorter the time, the greater [...]
