By all measures, graphene shouldn’t exist. The fact it does comes down to a neat loophole in physics that sees an impossible 2D sheet of atoms act like a solid 3D material.
A team of scientists from Imperial College London have proposed a laser model that can could heat materials to temperatures hotter than the center of the Sun in just 20 quadrillionths of a second. That’s 10 million degrees Celsius almost instantaneously.
A home battery that is cheap, durable, safe and as big as you like that could store solar or wind power is closer to reality. Harvard University researchers report that they have tested a “flow battery” that uses cheap and abundant chemical elements, can be operated with plastic components, will not catch fire and can operate at 99 percent efficiency.
The Wave Solar is a home energy generator that makes electrical power, heat, hot water and air conditioning from a solar thermal panel. The system is backed up by natural gas or propane for cloudy days or if the power goes out at night.
Wave Solar is one of the featured exhibitors at the DaVinci Inventor Showcase. The Inventor Showcase will take place October 10-11, 2015 at the NoCo Maker Faire. You will have a chance to take a look at the Wave Solar and many other amazing inventions.
According to Florida State University (Tallahassee) a new formulation for light-emitting-diodes (LEDs) could make lighting systems using the as cheap as incandescent bulbs, . FSU has come up with an inexpensive single layer combo-organic/inorganic material formulation that can glow red, green or blue (or all three together for white LEDs).
