Ingo Burgert and his team at public research university ETH Zurich and Swiss Read more about These researchers in Switzerland can get electricity by compressing wood[…]

‘Wearable microgrid’ uses the human body to sustainably power small gadgets using sweat and motion

Nanoengineers at the University of California San Diego have developed a “wearable microgrid” that harvests and stores energy from the human body to power small electronics. It consists of three main parts: sweat-powered biofuel cells, motion-powered devices called triboelectric generators, and energy-storing supercapacitors. All parts are flexible, washable and can be screen printed onto clothing. Read more about ‘Wearable microgrid’ uses the human body to sustainably power small gadgets using sweat and motion[…]

Two Companies are Turning Airborne CO2 into Diamonds

two companies are selling diamonds made in a laboratory from CO2 that once circled the Earth. […] Each carat of a diamond removes 20 tons of CO2. That, he said, is more invisible gas than the average person produces in a year. With the purchase of a 2-carat diamond, Shearman pointed out, “you’re essentially offsetting Read more about Two Companies are Turning Airborne CO2 into Diamonds[…]

Scientists turn CO2 into jet fuel

Researchers may have found a way to reduce the environmental impact of air travel in situations when electric aircraft and alternative fuels aren’t practical. Wired reports that Oxford University scientists have successfully turned CO2 into jet fuel, raising the possibility of conventionally-powered aircraft with net zero emissions. The technique effectively reverses the process of burning Read more about Scientists turn CO2 into jet fuel[…]

Korean artificial sun sets the new world record of 20-sec-long operation at 100 million degrees

Iron Powder Passes First Industrial Test as Renewable, Carbon Dioxide-Free Fuel

While setting fire to an iron ingot is probably more trouble than it’s worth, fine iron powder mixed with air is highly combustible. When you burn this mixture, you’re oxidizing the iron. Whereas a carbon fuel oxidizes into CO2, an iron fuel oxidizes into Fe2O3, which is just rust. The nice thing about rust is that Read more about Iron Powder Passes First Industrial Test as Renewable, Carbon Dioxide-Free Fuel[…]
