CleanAir: All-In-One Air Conditioner and Cleaner Promises 25% Energy Reduction
"Every second we pump air into our houses that is too hot, too cold or too moist. And then we spend billions of kilowatts treating that air; cooling it, heating it or dehumidifying it. If we could clean the air, we could recycle air that already has the perfect temperature," explains Matthew Johnson, a professor at the University of Copenhagen, who invented "CleanAir", the device that acts like an all-in-one dehumidifier, cooler, heater, and cleaner.
New Portable Wind Turbine Produces Electricity Anywhere And Is Operated By Just One Person
Designers have come up with a new portable wind turbine that is very easy to be transported and put into function by just one...
Spin-Seebeck Effect Causing New Magnetic Semiconductor To Become Energy Harvester
A gallium manganese arsenide semiconductor may be the material to revolutionize how electronic circuits power and recycle their waste heat, through a research of Ohio State University scientists, led by Joseph Heremans and Roberto Myers, both from OSU.
PowerBuoy-The United States' First Tidal Power Generator Connected To The Grid
Last year, the Ocean Power Technologies (OPT) company has developed a tidal power generator that has now been connected to the energy grid at the Marine Corps Base Hawaii as part of the firm's program with the US Navy to test wave energy technology, giving the US their the first-ever grid connection for a wave energy device.
Ukrainian & American Team Makes Ferroelectric Nanowires Harvest Heat Differences
A team of Ukranian and American scientists have discovered that by using structures called ferroelectric nanowires, they can generate electricity from a temperature difference. This concept is now new, but rather uses different approaches and materials. It can harvest energy by using the temperature difference between materials and/or ambients.
Nanoscale Thin Film Solar Cell Absorbs 12 Times More Light Than Macro-Sized Counterparts
Light behaves differently in macro- and nano- scale environments, and this could be a starting point for those researchers who want to improve the solar cells' efficiency. It was a starting point for some Stanford engineers, who found out that light ricocheting inside an ultra-thin polymer film solar cell behaves differently than if the film wasn't so thin. The difference is enormous.
Efficient Vertical Axis Wind Turbine Concept by Sauer Energy
Vertical axis wind turbines have recently been revived by a few innovations made to them by scientists all over the world. Sauer Energy is one of them, and their turbine has a high efficiency because it's designed to maximize the drag, so the blades are moved more efficiently by the wind.
Three South Florida Schools Received Solar Panels Donated by FPL Group
Three South Florida schools (Deerfield Beach Middle School, Mandarin Lakes K-8 Academy in Homestead and SunCoast Community High School in Riviera Beach) have received solar panels from FPL Group Foundation. This way the schools will start saving money and teaching students about renewable energy.
Solar Wind Power Harvesting Satellite Could Produce 100 Billion Times More Energy Than We...
I've been hearing at least two versions of how we should construct an orbital power station, that would harness the Sun's power and transmit it through lasers or microwaves to Earth. Those concepts, along with classic solar and wind power fade when compared to this one.
SolarEagle: Boeing's Future Unmanned Aircraft Able To Stay Aloft For More Than 5 Years
The US military's DARPA has signed an $89 million deal with Boeing for the development of a solar powered, unmanned aircraft that could stay aloft for more than five years. Of course, the aircraft would be used in espionage purposes, but the concept is also a testing ground for civilian purposes.
