EnergySail promises wind-solar combo for cleaner shipping

Many shipping companies are experimenting with adding sails to cargo vessels. Here's a design in which the sails are also solar panels.

EnergySail is a concept by Japan's Eco Marine Power that harnesses and stores wind and solar power to reduce fuel costs and pollution. It would work as an additional source of power to a ship's main engines.

The devices would be fitted on anything from large bulk ore carriers to cable-laying ships, ferries, and coast guard patrol vessels, according to the company. An automatic control system would orient the sails and panels to catch the … Read more

Samsung solar-powered school shines in rural South Africa

There's something new(ish) under the sun in the rural South African village of Phomolong, where Samsung has built a gadget-laden solar-powered classroom -- in a renovated shipping container.

The Solar Powered Internet School -- a product of Samsung's corporate-social responsibility initiative -- has solar panels on the roof that can generate nine hours of electricity a day. That power's needed to juice the electronics inside -- a 50-inch electronic board, Samsung Internet-enabled solar-powered notebooks, Samsung Galaxy tablets, and Wi-Fi cameras.

Titan supercomputer debuts for open scientific research

Forecasting for weather like this week's "Frankenstorm" may become a lot more accurate with the help of the Department of Energy's Titan supercomputer, a system that launched this month for open research development.

The computer, an update to the Jaguar system, is operated in Tennessee by Oak Ridge National Laboratory, part of the DOE's network of research labs. Researchers from academia, government labs, and various industries will be able to use Titan -- believed to be one of the two most powerful machines in the world -- to research things such as climate change and … Read more

Recycled-plastic Levis: Do these bottles make my butt look big?

Your next pair of Levi jeans may include black trays, brown beer bottles, clear water bottles, and green soda bottles. The new WasteLess collection uses polyester fiber made from crushed plastic recyclables. The bottles are collected from municipal recycling programs around the country.

Both jeans and trucker jackets will be available. Plastic pants don't sound very comfortable, but the plastic parts only take up about 20 percent of the cloth. The recycled fiber is mixed with cotton fiber so you get a pant that feels like regular denim.… Read more

Government-funded battery maker A123 files for bankruptcy

A123 Systems, a lithium-ion battery maker that has received hundreds of millions in government support, filed for bankruptcy protection today.

The move makes A123 the latest government-backed energy company to file for Chapter 11. Many of these companies have struggled to make money as demand slows for their products. A123 received more than $250 million in state and federal funding to help it run its operations providing batteries for electric cars and other products. But it has also faced many problems, including defective products.

A123 today said Johnson Controls will help finance the filing by buying A123's automotive business … Read more

Nest 2.0: Slimmer, sleeker thermostat smarter than ever

When the "Father of the iPod" Tony Fadell unveiled Nest, the "learning thermostat" last fall, it was likely the first time anyone had ever thought of a thermostat as sexy.

Researchers unveil ultra-thin electronics that dissolve in body

The same researchers who last year developed "electronic tattoos" that bend and stretch on skin are now unveiling similar ultra-thin electronics, only these dissolve when their job is done.

Made of silicon, magnesium, and magnesium oxide and surrounded by a protective layer of silk, these "transient" electronics aren't built to last but rather to melt away and, in the process, reduce the need to pass or surgically remove tiny medical implants, researchers from Tufts and the University of Illinois write in the current issue of Science.

The researchers -- who have begun using their devices … Read more
