Hydrogen Cheaper Than Gasoline: Thanks To Nanoparticles

Ovidiu Sandru — Fri, 29 Feb 2008 09:43:32 +0000

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 […]

Moth Eyes Inspiration For New Generation Solar Cells

Ovidiu Sandru — Tue, 26 Feb 2008 18:18:48 +0000

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 all […]

Bluenergy: Wind and Solar Power in One Piece

Ovidiu Sandru — Tue, 26 Feb 2008 17:32:59 +0000

The 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 […]

A Soda Can Powered Solar Garage Heater

Ovidiu Sandru — Sun, 24 Feb 2008 17:42:25 +0000

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 […]

Nano Fibers Will Power Your iPod

Ovidiu Sandru — Sun, 17 Feb 2008 16:18:09 +0000

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 […]

UltraBattery – the image for future electric power

Ovidiu Sandru — Mon, 11 Feb 2008 09:52:25 +0000

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 […]

Nano Flakes: more power from the Sun

Ovidiu Sandru — Sun, 10 Feb 2008 20:25:33 +0000

Dr. Martin Aagesen, a researcher at the University of Copenhagen and director of SunFlake Inc. is currently developing a technology called “Nano Flakes”. Nano Flakes are semiconductors with a perfect crystalline structure, and they can absorb about 30% of the solar energy applied to them. “I discovered a perfect crystalline structure. That is a very […]

Do you agree to genetically mutate trees for ethanol production?

Ovidiu Sandru — Sun, 10 Feb 2008 13:56:21 +0000

Here we go again. A few weeks ago I wrote an article about some scientists inventing a way to modify the DNA of a bacteria to produce hydrogen. Ok, I didn’t fully agree with that – considering that bacteria is an extremely small microorganism, and you don’t know what ecological disaster it might produce when […]

Quasiturbine Engine Works With Air

Ovidiu Sandru — Wed, 06 Feb 2008 07:40:53 +0000

Since the Quasiturbine is a pure expansion engine (which the Wankel is not, neither most of other rotary engines), it is well suitable as compressed fluid engine – Air engine or air motor. From the basic 200cc per revolution engine bloc, a compressed air prototype has been built making use of 2 parallel expansion circuits […]

The Tesla Oscillator (aka Earthquake Machine)

Ovidiu Sandru — Wed, 06 Feb 2008 07:28:27 +0000

Nikola Tesla is primarily thought of as an electrical genius, but he also was responsible for a number of mechanical devices. One of the most notorious of these was his “Earthquake Machine” otherwise known as the Tesla Oscillator. The machine which Tesla tested was small, around seven inches long, and weighing only one or two […]

The "reasonable" price of free energy

I know there’s a lot of talk on the internet about “how to produce the free energy”, “how to capture it” or simply how to lower or eliminate your monthly bills (electricity, gas, heating). In fact, the energy harvested here, on this site, doesn’t come for free. It simply exists in space and time and […]

Solar Power Gets Cheaper (video)

Ovidiu Sandru — Sat, 02 Feb 2008 08:38:19 +0000

There have been many trends posted involving solar power but in the US it still only accounts for 1% of the electricity generated. Even though it is getting cheaper the main barrier is still the cost. Although growing investment, technological breakthroughs and lower prices have lead to an increase in sales, which lowers prices further […]

A fuel cell that automatically throttles its power

Ovidiu Sandru — Wed, 30 Jan 2008 09:15:04 +0000

A fuel cell that efficiently regulates its own power output based on the amount of hydrogen it is fed has been developed by US researchers. The simple control mechanism could extend the range of devices that can practically be powered using fuel cells. Fuel cells generate electricity by combining hydrogen and oxygen to produce electricity […]

Indeed, it does seem that the Earth will run out of oil, natural gas and coal much more quickly than was, originally, anticipated by researchers keeping track of overall expenditure of these resources [1]. At the same time, others warn that any expectation of nuclear power taking over as an effective substitute is both unrealistic […]
