Air-Purifying Concrete Paving Stones Remove Nitrogen Oxides from Vehicle Emissions
Researchers from the Eindhoven University of Technology in the Netherlands claim to have invented a new type of paving material that actually removes some pollutants from the air as vehicles travel over the surface. Combined with concrete or normal asphalt, the new material is able to eliminate 25% to 45% of nitrogen oxides from vehicle gases.
DIY Girl From Ohio Builds Her Own Electric Bike From Scratch – See How
It looks like men are not the only ones who love technology, welding, batteries and electric motors. After presenting the example of Eva HÀkansson, 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.
Berkeley Researchers Advance In Studying How Magnets Can Be Used in Fridges
According to the researchers, in the future, our refrigerators could use magnets to keep the food cold. Besides the fact that one such refrigerator uses less power and runs quieter than a conventional fridge, it wouldn't contain any hydrofluorocarbons (HCF), gases that contribute to the greenhouse effect.
New Organic Framework for More Efficient Graetzel Solar Cells Discovered
Scientists from Cornell University have unveiled a basic process that could give solar cells a boost in efficiency and a drop in price. The process employs molecules typically used in coloring blue jeans and in ink dyes. Their purpose if to build an organic framework that could serve as a building block for cheaper and flexible solar cells.
The Morning Challenge Suggests Japanese People To Wake Up 1 Hour Earlier For Saving...
It looks like the Japanese aren't going to stay behind the English with daylight saving (or vice-versa), and launch a campaign that encourages people to change their wake-up and sleep time one hour earlier to save lots of tons of emitted carbon dioxide.
Jake Explains How to Build a Super-Cheap Solar Water Heater
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.
Scientists Explain Limitations of High Temperature Superconductors in High Currents
Since their discovery in late 1980s, superconductors were thought to revolutionize everything that had an electric current flowing, but allowing it to pass through more easily, and with much less heat produced. Ultra-efficient magnetic trains had been envisioned, then, but ...
EnduraLED from Philips Lasts for 25,000 Hours and Saves You Money
Incandescent light bulbs are fading away as their younger LED brothers come to the market and get cheaper by the day. A new innovation from Philips, called EnduraLED, can provide as much light as a 60W incandescent bulb, but in the meanwhile consuming only 12 W from the wall socket, thus extending its applications in the mobile lighting / solar powered territory.
DEVap: Innovative Air Conditioner Uses 90% Less Energy to Cool Things Down
DOE's National Renewable Energy Laboratory (NREL) has combined three classic methods of cooling down the air into one invention that could save 50 to 90 percent of your monthly electricity bill (on air conditioning). The invention is called "DEVap" (Desiccant-Enhanced eVaporative air conditioner).
LG Electronics Launches Solar Powered Hybrid Air Conditioner
Warming up in winter by using the Sun is one thing, but cooling down in the summer by using the same Sun is way more interesting. LG Electronics just announced yesterday that they will launch their first air conditioner powered by a solar panel.
