Cheaper, Silent, Bladeless Wind Turbines

Cheaper, Silent, Bladeless Wind Turbines

In 1940, the newly built Tacoma Narrows Bridge began to vibrate violently and soon collapsed in windy conditions. Ever since, engineers have focused on ways of stopping their structures vibrating in this way. Now, a group of Spanish engineers is working to harness the energy potential of vibrating structures. Instead of using the wind to […]  Read more »

Energy-saving Smart Facades

Researchers and designers at Germany’s Fraunhofer Institute have developed a building façade element which uses the sun’s energy to shield the building’s interior from the sun.  Read more »

Hybrid Supercapacitors Promise Large Storage and Fast Charging

Hybrid Supercapacitors Promise Large Storage and Fast Charging

Scientists at UCLA have developed hybrid supercapacitors that can store as much charge as a lead acid battery, yet can be recharged in seconds compared with hours for conventional batteries.  Read more »

Fueling Vehicles with Hydrogen from Corn Waste

Fueling Vehicles with Hydrogen from Corn Waste

Researchers have found a way to make hydrogen fuel by a biological method that uses cheap and abundantly available corn stover (the stalks, cobs and husks) and greatly reduces the time it takes to produce the fuel.  Read more »

Aluminium Battery – Safer & Cheaper Than Lithium

Stanford University scientists have developed the first high-performance aluminum-ion battery that’s fast-charging, long-lasting and inexpensive.   Read more »

Packing Peanuts Provide Power

Packing Peanuts Provide Power

Scientists have developed a heating process that converts the “peanuts” used for packaging into carbon anodes for lithium batteries.
As well as eliminating waste, the technique produces batteries that recharge much faster because the carbon anodes are only a tenth as thick as their commercially available counterparts.  Read more »

Electric Cars Could Reduce Temperatures in Cities

Electric Cars Could Reduce Temperatures in Cities

Researchers have shown that replacing conventional cars with electric ones could not only cut emissions from cars but it could also lower emissions of carbon dioxide by cutting the use of air conditioning.  Read more »
