Tesla home battery, which is currently produced for SolarCity's home energy storage system...

The same lithium-ion battery technology that powers Tesla’s electric vehicles will be used to develop a battery for the home, according to a statement by CEO Elon Musk during a recent conference call with analysts. The batteries would be used by homes and businesses to store excess energy generated from solar panels during the day, and drawn from at night when panels sit idle.  Read More

The energy-harvesting tree collects energy from light, temperature differences, and vibrat...

In January, the VTT Technical Centre of Finland unveiled its decorative, mass-producible organic photovoltaic (OPV) leaves designed to capture energy from interior lighting to power small devices and sensors. Now, the company has followed the logical path and come up with an energy-harvesting tree that generates electricity from a variety of sources.  Read More

Brio can tell the difference between a kid's fingers and an electrical appliance

Most of us have a number of power outlets dotted around the house, and each one is a potential hazard to inquisitive little fingers. Brio promises a safer and smarter power outlet that can tell the difference between a kid's fingers and an electrical appliance, only turning on the juice for the latter.  Read More

The Envirotouch switches can replace standard switches and outlets and automatically shut ...

The modern home is chock-full of electrical appliances, many of which remain on standby when not in use and add unnecessary bulk to our energy bills. Thankfully, those looking to trim down on power usage aren't exactly short of options, with many devices emerging over the years designed to shut off our appliances at the wall. The Envirotouch is the latest take on the smart, energy-saving switch, relying on one-touch timer buttons to cut power to our appliances soon after we stop using them.  Read More

Engineers at Penn State University have produced an ammonia-based battery that captures an...

As modern power generation methods are designed to squeeze the most power from the least amount of fuel, engineers are constantly looking at techniques to improve efficiency. One way to achieve this is to scavenge waste energy left over from the production process to capture and convert low-grade heat into usable energy. In pursuit of this goal, engineers at Pennsylvania State University have produced an ammonia-based battery that not only captures and converts waste heat economically and efficiently, but is claimed to do so at a greater capacity than other similar systems.  Read More

Dr Shahriar Hossain is developing a wind turbine that uses a magnesium diboride supercondu...

Conventional offshore wind turbines are expensive and complicated pieces of machinery – in a large part because of their complex and maintenance-intensive gearboxes. Dr Shahriar Hossain from the University of Wollongong in Australia is looking to slash production costs and drastically improve efficiency replacing these gearboxes with a superconducting coil.  Read More

Natural vibrations caused by two surfaces with different work functions repelling and attr...

Electrical energy is normally generated through heat, motion, nuclear transformation, or chemical reactions, but now scientists at VTT Technical Research Center of Finland have devised a new method that involves mechanical vibrations. They figured out how to "harvest" the vibrational energy that occurs naturally when two surfaces with different work functions are connected via electrodes, and this energy could potentially be used to power wearables and other low-power electronics.  Read More

Scotland's Whitelee wind farm (Photo:

Scotland is pushing ahead with green energy, with First Minister Alex Salmond claiming that renewables could provide 100 percent of Scotland's energy by 2025. And last month, Salmond's push for wind farms appears to have borne fruit – wind power alone generated some 126 percent of the energy needed to power every home in Scotland in what the World Wildlife Foundation (WWF) is calling a "bumper month." Even solar fared well despite the chilly conditions, with domestic solar PV panels chipping in around a third of the domestic energy bill.  Read More

The world's first solar bike path is set to open in the Netherlands next Wednesday. The SolaRoad will run through Amsterdam's northern suburb of Krommenie and will feature concrete slabs embedded with solar panels to convert energy from the sun into electricity for the grid.  Read More

Researchers at the University of Utah have created a jet-fuel powered fuel cell that runs ...

Engineers at the University of Utah have developed and built the very first fuel cell using jet fuel that operates at room-temperature without the need to ignite the fuel. Using enzymes to help produce electricity, these new fuel cells have the potential to power everything from portable electronic devices to cars and off-grid power systems.  Read More
