I have heard about cars running on electricity, on biofuels, and other kinky stuff, but this one surpasses them all. Two brothers, Petru and Gheorghe Bordeianu, from Bacau, Romania, have invented an engine that runs totally on a combination of vinegar, water and a certain “soft drink”.

Silicon photovoltaic cells are preferred in today’s market conditions and technological implementations because they are cheap, silicon is abundant and the ongoing research has made them more and more efficient. Still, manufacturing the PV cells is very energy consuming, and silicon PVs are very fragile and prone to breaking in the most mildly hostile situations [...]

If we could somehow invent a reliable technology that could “eat out” all the excess CO2 from the atmosphere in a large scale, we could turn back to where we started from a hundred years ago, reducing global warming and the change of climate.

Using microscopic creatures as our friends is not a new idea, not it has been used recently. Nowadays, pushed by our green energy needs, we have to find solutions by using and probably killing some of our little friends to make us energy. This phrase sounded like the madhouse, now let’s get to the real [...]

Light and water are both involved in the process of green plants’ photosynthesis. Scientists have been trying to find out the deep truths of how plants acquire their energy from the Sun, split the water, generate oxygen, and create hydrocarbons, eating CO2 out of the air.

As if it wasn’t enough for MIT’s virus batteries, scientists from the University of British Columbia have now devised a fuel cell prototype able to feed itself from the sugar in the blood stream.The tricky part of the invention is that the fuel cell is made of nothing else but a type of bacteria, Saccharomyces [...]

Fuel cells are said to be the next big thing in the auto industry. In fact, they already are the next big thing. Fuel cells take advantage of the joining force between the oxygen and the hydrogen, and create electricity, used to drive anything (a car, more commonly). Price is a prohibitive variable in fuel [...]

“Oh, yes! In 25 years we could take over the world” - says Dan Zaslavsky, professor at the Institute of Agriculture of Israel. He and his team devised an Energy Tower working on the principle of rising hot air and lowering the cold one. That is the simple idea. They work on the project since [...]

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 [...]

Solio has made a gadget that can power your small handheld devices, such as your PDA, cellphone, or your GPS when you travel. It’s made from three solar batteries backed up by a rechargeable battery. When you’re out of power and you have nowhere to plug in, just get out your Solio from your bag [...]

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 [...]

Two UK researchers, David Worsley and Maarten Wijdekop have made up a paint that could produce electricity by gathering the energy from the Sun. A consortium led by Swansea University in the UK hopes to use that process to cover steel sheets with a photovoltaic paint at up to 40 square metres per minute.The paint [...]

Nanosolar has created a thin film solar battery, much more efficient than anything existing on the market nowadays.
Its thin film technology transfers the sun light in a very efficient way. The Nanosolar power plant will begin producing energy in 2008 and will cover 430 megawatts/year. That’s more than all the capacity of the currently installed [...]

We have been talking a while ago about refrigerators that needed no electricity or that were powered by the Sun, through evaporation, helping poor countries with a cool place to keep their food. Now, venture capitalist Adam Grosser teamed up with some Stanford scientists to create refrigerator that really doesn’t need to be plugged in [...]

The Japanese researchers continue to amaze me each and every time they get something out of their minds. In a time when the world trades solar panels, wind turbines, wave power, nuclear power, what do you think they do? Have you seen the movie “Flubber”?
After the hit with the water powered car, the Japanese researchers [...]
