Swedish media, including the website of the Dagens Nyheter daily, reported Thursday that Mohamed Altoumaimi had found a formula to explain and simplify the so-called Bernoulli... [read more]

Brunton makes a good range of flexible solar cells that use CIGS (Copper Indium Gallium diSelenide) instead of the usual silicon. The Brunton Solaris 26 is a flexible solar charger that generates 26 watts but measures only 21.5” by 37.5″ and folds down to 11″ by 8.5” by 1”. Solaris chargers can charge a laptop or digital video camera. They can power a satellite or cell phone. It takes between... [read more]

Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond. The scientists also calculated that another material, lonsdaleite (also called hexagonal diamond, since it’s made of... [read more]

A new carmaker has a plan for cheap, environmentally friendly cars to be built all over the country An air-powered car?

  A company called GreenCore Air has released an air conditioner than can be powered by a single 170 watt solar panel. The GreenCore air conditioning unit can heat and cool a 600 square foot room. It runs on DC power, so there is no need to put an AC inverter between the solar panel and the air conditioner. This eliminates the power losses associated with converting AC to DC.   When the... [read more]

Abstract Can a book that doesn't come from comprehensibly materialized textual means still be considered a book? What happens when, in the form of an electronic publication on the World Wide Web, a typical book-type volume is designed to be networked and includes multi-media? As the physical object itself disappears, one of the conditions required for the existence of book science faces extinction... [read more]

There have been pen phone concepts before, even a few working products, but none as slim and small as this one sent us by an anonymous tipster. He told us this "design A" is not a finished product yet, and added that the undisclosed company he's working for wants to gauge interest in such a device. While most users will connect the phone to Bluetooth earpieces, those two target-shaped areas on... [read more]

In 1878 Thomas Edison invented the first electric light bulb. This single invention proved to be so popular that it caused a major recession in the oil industry. Since 1856 kerosene lamps were used in homes and street lamps. Historians state that the introduction of kerosene initiated the oil industry. Sales and production of kerosene trickled to a standstill as electricity and the electric light bulbs... [read more]
