Micro petrol engine

New mini petrol engine

New mini petrol engine

SCIENTISTS have built the smallest petrol engine ? tiny enough to power a WATCH.

The mini-motor, which runs for two years on a single squirt of lighter fuel, is set to revolutionize world technology.
It produces 700 times more energy than a conventional battery despite being less than a centimeter long ? not even half an inch. It could be used to operate laptops and mobile phones for months on end ? doing away with the need for recharging(...)

Aerial ropeways: automatic cargo transport for a bargain

Aerial ropeways: automatic cargo transport for a bargain

These days, we use them almost exclusively to transport skiers and snowboarders up snow slopes, but before the 1940s, aerial ropeways were a common means of cargo transport, not only in mountainous regions but also on flat terrain, with large-scale systems already built during the Middle Ages.

Cargo tramways can be fully or partly powered by gravity, and some deliver excess power that can be utilized to generate electricity or to drive cranes or machinery in nearby factories. Some innovative systems have been constructed in recent years.

A brave new world of fossil fuels on demand?

A brave new world of fossil fuels on demand

In September, a privately held and highly secretive U.S. biotech company named Joule Unlimited received a patent for “a proprietary organism” – a genetically adapted E. coli bacterium – that feeds solely on carbon dioxide and excretes liquid hydrocarbons: diesel fuel, jet fuel and gasoline. This breakthrough technology, the company says, will deliver renewable supplies of liquid fossil fuel almost anywhere on Earth, in essentially unlimited quantity and at an energy-cost equivalent of $30 (U.S.) a barrel of crude oil. It will deliver, the company says, “fossil fuels on demand.”

This Solar Charger Runs Devices Directly

"According to Suntactics, its new PC5 unit is different from other portable solar chargers in that it doesn’t send power to an internal battery that then charges your device. Competing products, Suntastics says, “are literally charging a battery from a battery. The solar panels on them are too weak to charge the USB handheld device directly.” Not so with the PC5: “The PC5 solar charger has 5 watts of solar power potential as compared the ~2 watts in most of the other chargers. The PC5 will not only charge the USB handheld device, it will run it on dead batteries.”

Deep Green Underwater Kite

Deep Green Underwater Kite

Swedish company Minesto's underwater kite resembles a child's toy as it swoops and dives in ocean currents. But since seawater is 800 times as dense as air, the small turbine attached to the kite — which is tethered to the ocean floor — can generate 800 times more energy than if it were in the sky. Minesto calls the technology Deep Green and says it can generate 500 kilowatts of power even in calm waters; the design could increase the market for tidal power by 80%, the company says. The first scale model will be unveiled next year off the coast of Northern Ireland.
