The future of easy home energy monitoring may be a little bit closer, thanks to a government initiative designed to allow consumers direct access to their energy consumption data.
The White House’s new Green Button gives utilities a way to simplify and standardize sharing usage statistics with their customers via a one-click download. Two California providers, Pacific Gas & Electric and San… → Read More
Buildings are blamed for as much as 40% of U.S. energy consumption, and while green construction is on the rise, identifying the best ways to make and older building more efficient can be a tedious manual endeavor. Retroficiency, whose aim is to disrupt the energy efficiency market, eases the process with the help of extensive data sets and predictive analytics. → Read More
Flying a kite to produce power may conjure up images of Ben Franklin, who sought to prove lightning was electric. Makani Power releases turbine blades into the air, seeking to harness wind energy at higher altitudes. → Read More
Spiderman might soon lose his dominance in harnessing spider silk superpowers. Scientists from the University of Wyoming, the University of Notre Dame and Zhejiang University in China have genetically modified silkworms to spin stronger silk using spider genes.The new material could be used for everything from bulletproof vests to replacing tough plastics. → Read More
In an unusual hybrid, British industrial designer Phil Pauley created Marine Solar Cells that harness energy from both the sun and water.
The web of energy generators capture energy off-shore, using a combination of floating photovoltaics and natural buoyancy displacement. Thanks to the reflective nature of water, the solar component’s efficiency is up to 20% greater than it would be… → Read More
German researchers are testing a unique form of public transportation that borrows the best from busses, electric cars, trains and trams without contributing emissions. The vehicle, named AutoTram, is fully electric, but instead of running on a single charge, it charges when it stops, gaining enough power in 30 seconds to move another mile.
The project comes from the Fraunhofer Institute for… → Read More
Even though plants need only a few things to grow – water, air, light and minerals – maintaining the right proportions can make gardening feel like a high-maintenance hobby. Estonian company Click & Grow creates soilless, electronic flowerpots that do the work for you, providing the correct water and nutrient balance for indoor plants.
For some, this may seem like a superfluous product… → Read More
Most wind turbines have a recognizable shape, but a new design from Segway inventor Dean Kamen is less obvious in its functionality: This turbine is made of plastic fabric meant to be easily inflated by the wind.
Archetypal wind turbines require a good amount of steel and concrete to be built, and once installed, it is difficult to move them. Kamen’s design uses air to inflate the rotors… → Read More
A solar-powered light bulb may sound like an oxymoron (what’s the point of a lightbulb that only works when the sun’s out?), but a company called Nokero has a prototype in the works that will charge a battery in the light bulb, making it useful after sundown.
Denver-based Nokero, short for No Kerosene, hopes to offer a safe light source to the millions living without a reliable energy supply. → Read More
An uninhabited playground for green tech and innovative experiments is in the works to be built in New Mexico. The pseudo town will be used to research and test new green tech, wireless and traffic technologies in real-world-but-controllable conditions, like Sim City minus the citizens.
Washington, D.C.-based Pegasus Global Holdings, an international technology testing firm, is behind the… → Read More
One future source of green energy may be as close as the nearest dumpster thanks to companies vying to make fuel from trash. Enerkem, based in Montreal, and Fiberight, in Maryland, hope to turn municipal waste into energy in new biorefineries.
Enerkem has been around since 2000 and owns several facilities in Canada. Its pilot plant, in Sherbrooke, Quebec, turns used electricity poles into… → Read More
When it comes to renewable energy solutions, sometimes nature has the best ideas. That was 13-year-old Aidan Dwyer’s conclusion after a wintry hike in New York’s Catskill Mountains, a trip that inspired him to build a unique and effective solar array design.
Dwyer observed patterns in the trees and, after further research and contemplation, realized the branches matched up with the Fibonacci… → Read More
Aviation enthusiasts interested in greener flying might put an Elektra One plane on their wish lists. PC-Aero‘s electric aircraft can fly for up to three hours on one charge with a 100mph cruising speed. The charging happens inside a solar-powered hangar included in the plane’s anticipated purchase price of $145,000. → Read More
Those who resist purchasing an electric car because charging stations are less ubiquitous than gas stations or figuring out how to charge your car at home seems complicated have one less excuse to go green. A new system from British startup HaloIPT allows cars to be charge wirelessly using induction.
The wirelessly transmitted power goes to the car’s battery for an ongoing charge, similar to… → Read More
For many people, building with Legos brings back fond memories. For Mike Schropp, the memories are still being built. Schropp loves Legos, often incorporating them into technology. For his latest project, Schropp built a 12-core PC tucked into a custom made case he designed using some 2,000 black Lego bricks. The finished product is not only awesome looking, but also energy efficient. → Read More
Group buying is moving into the commercial clean energy space thanks to Solar@Work, a program designed by San Francisco’s Department of the Environment to make solar panels more affordable for business owners. Businesses have three options for acquiring solar panels through the program: Purchasing, leasing, and securing a loan. A federal grant covering 30% of installation costs is also on… → Read More
Wood-burning stoves aren’t known for being particularly efficient, and their smoke not only contains high carbon emissions but causes health risks to those who inhale it. A portable design from BioLite aims to tackle this problem and turn the stove into a cell phone charger in the process.
The stove converts heat energy into electricity, powering a small fan to improve the wood’s combustion. → Read More
What’s more impressive than a car that can do over a thousand miles per gallon? One that was designed by school kids.
In the UK, students from regional schools and universities took part in the annual Mileage Marathon Challenge near Leicester, England, each team vying to set new gas mileage efficiency records in a race around a track. Cars were allowed to coast, but had to maintain a minimum… → Read More
