Amazing Quantum Levitation Technology Could Open the Door to Floating Vehicles!

Levitation isn't just for Houdini anymore. A team of researchers at Tel-Aviv University has discovered a way to make objects float in mid-air using a process called quantum levitation, and they think the tech could even lead to floating alternatives to traditional gas powered vehicles. More ...

Lithium-Ion Batteries Made Faster With New Process

The latest development by German engineers is inspired by nature. To fill the porous electrodes of lithium-ion batteries more rapidly with liquid electrolyte, they use a physicochemical effect that also provides water transport in trees. The new process increases the throughput of battery production and reduces investment costs. This and other innovations will be presented by KIT at the eCarTec International Electromobility Fair in Munich from October 18 to 20. More ...

Bricks made from sewage cut carbon emissions

The making of traditional cement, the primary component of concrete, accounts for five to ten percent of global carbon dioxide emissions. By combining ash from incinerated sewage with a vegetable oil based binder, UK based Encos have introduced masonry blocks and bricks that reduce greenhouse gas emissions by estimates of 160 percent for blocks and 120 percent for bricks.

Can hot air be the free fuel of the future?

For centuries, architects have taken advantage of rising heat to help cool some structures. Solar chimneys allow the rising air to go out of the building, taking the heat with it.

Today, Australian entrepreneur Roger Davey wants to take advantage of that phenomenon -- with a twist.

He wants to create, capture and control hot air to help power cities. He plans to build a huge solar updraft tower, 2,600 feet tall, in the Arizona desert. As the hot air moves into the tower, it would turn 32 turbines, spinning them fast enough to create mechanical energy, which generators convert to electricity. More ...
