IBM Invents Way to Both Cool Down Concentrated Photovoltaics and Desalinate Water
IBM is seemingly more and more concerned about green technologies, and now invests in a project that can solve the problem of cooling solar cells that would otherwise be hard to use because of the high temperatures they're exposed to (120°C), aka concentrated photovoltaics.
Contaminated Waters to Be Treated with Forest Debris and Crushed Shells
With the risks nuclear reactors are posing in every country, a solution had to be found for waste to be extracted. Thanks to researchers at the University of North Carolina, a material has been found, which on top of everything is 100% natural: forest debris mixed with crushed crustacean shells.
Growing Cannabis Indoors Emits CO2 Equivalent of 3 Million Cars Yearly
Although indoor pot growers should be aware that their plants consume the electricity needed to power 2 million average-sized homes, I don't think they care. Indeed, a study conducted at the LBNL (Lawrence Berkeley National Laboratory) shows that those who grow marijuana indoor represent about 1% of the energy consumed in the US - which is much.
Scientists Using Microwaves to Turn Waste Motor Oil Into Usable Fuel
British scientists from the University of Cambridge have developed a method of converting waste motor oil into diesel to be used in any diesel engine. By using microwaves and a specially-designed material, they burn the oil in the absence of oxygen, a process called pyrolysis.
New Polymer That Harvests Both Heat and Light Invented at Wake Forest University
One day we will get as far as taking a shower and turning on the heat in our room with the energy our roof has collected over the day. And when I say this I feel encouraged by the new solar-thermal device based on polymer material that Wake Forest University researchers invented.
Nanowires Could Enable Human Heart to Power Gadgets
Nanotechnology - the science of managing matter at a molecular level - has delivered its promises: if charging your iPod with your heart is...
T-box: A New Device That Harnesses Wind Energy Produced by Running Trains
Designers Ale Leonetti Luparinia and Qian Jiang have come up with a new concept of a device that uses the wind energy produced by a running train. As the designers claim, the device, dubbed T-box, is a power generator that is able to harnesses wind power when a train moves across the tracks.
Solarball: Ultra-Cheap Solar-Powered Water Purifier for The Poorest of Us
Technology doesn't always have to be complex to help people. Such is the case of a simple solar-powered water purifier designed by Monash University graduate student Jonathan Liow to help people in poor countries that have no access to drinkable water sources. The Solarball, his invention, can produce up to three liters of water per day.
New Gallium-Nitride LED Technology Offers High-Power Lighthing
All of the LEDs you see in every device that you put your hands on is made with precious sapphire rock - artificially grown one, but still an expensive material to work with. A new technology developed by Bridgelux uses Gallium nitride to grow LEDs on silicon substrates and can be reproduced at commercial scales.
Revolutionary Water Purifier Made From Banana Peels Eliminates Toxic Metals
A water purification system developed recently by Gustavo Castro and his colleagues from Brazil is actually based on banana peels, with no other complex filters or other electronics involved.
