UCLA researchers have designed a device that can use solar energy to inexpensively and efficiently create and store energy, which could be used to power electronic devices, and to create hydrogen fuel for eco-friendly cars. "This could dramatically lower the cost of...read more
Novel approach utilizes high mobility two-dimensional electron gas, boosting thermoelectric conversion efficiency. D electron gas (2DEG) More than 60% of the energy produced by fossil fuels is lost as heat. Thermoelectric energy conversion has attracted much attention...read more
Electronic devices such as computers generate heat that mostly goes to waste. Physicists at Bielefeld University have found a way to use this energy: They apply the heat to generate magnetic signals known as 'spin currents'. Spin Caloritronics In future, these signals...read more
This car is not a pipe dream it is a reality. It overcomes Simon's range anxiety, but may have created a new one with a $200,000 price. The new Tesla Roadster Performance Ferrari recently said it was not interested in electric cars. This will take a share of their...read more
There are other differences. While traditional 3D printers build parts from computer files, the cold-spray machine uses digital scans of actual jet engine parts to accurately reconstruct the broken part.read more
GE has the ability to print parts as large as 1 meter in diameter directly from a computer file.read more
The process looks something like a hi-tech sewing machine weaving an emblem onto a garment.
But soon the pattern begins to rise and swell, and a nose, constructed using a bio-ink containing real human cells, grows upwards from the glass, glowing brightly under an ultraviolet light.read more
