We've seen electric bikes before, but we've never seen anything like the Boxx.

This contraption, which looks like an oversize suitcase that sprouted handles--or a MacBook Pro on wheels, if you ask me--is actually a new all-electric bike made by a Portland-based company called Boxx. Its unique design certainly makes it stand out from the crowd, but so do its eco-friendly features.

The Boxx, is an emissions-free vehicle, can be charged using a standard household outlet system. It comes in two configurations: one with a standard Core power system that provides up to 40 miles of travel on … Read more

Startup SeaMicro first packed lots of low-end Atom processors into servers to save power and space. Now Intel's beefy Xeon server chips are also getting the low-power treatment.

SeaMicro today announced its SM 10000-XE server, which it claims is the most energy-efficient Xeon server ever built. It consumes one half the power of a server with comparable computing muscle, takes one third of the space, and increases the available bandwidth twelve times, the company said.

The company is one of few companies that have taken a radical approach to server design by using arrays of less powerful processors, called &… Read more

They say one man's trash is another man's treasure, and this certainly seems to be the case for Chilean artist Rodrigo Alonso.

Alonso is the mastermind behind the geeky chairs pictured above. They're made from pieces of old tech donated by Chilean recycling company Recycla.

The graphic designer creates the stools by pouring epoxy resin into a mold filled with the e-waste; the legs are made from cast aluminum. Alonso produces the chairs in limited editions, but he also takes special orders. Since no set of e-waste is alike, each piece is original and dyes can also be added to the resin to add color.

For Alonso, the project is more than just a piece of furniture or work of art. The chairs, which are called N+ew for No More Electronic Waste, is also about recycling e-waste. Though consumer electronics companies are slowly becoming more eco-conscious and more recycling programs are being put in place, the amount of e-waste is still expected to rise exponentially by 2020, especially in developing countries. … Read more

SOUTH BOSTON--From this grungy warehouse converted into a startup incubator, Sam White and Sorin Grama plot how to chill milk for poor Indian villagers.

The four-year journey of their startup, Promethean Power, has included several trips to India and dramatic engineering detours. Now finally, their rapid milk chillers, which feature a novel energy-storage technology, will be installed at three milk processing centers in India in the coming months.

The two company co-founders had originally intended to build a solar-powered milk chiller that would improve the lives of Indian farmers and advance renewable energy. But despite engineering some nifty power electronics, … Read more

DOE researchers are going to the nanoscale to pack more energy into fuel cell vehicles.

Lawrence Berkeley National Lab yesterday detailed research plans for a three-year, $2.1 million Department of Energy-funded project to develop materials that would improve hydrogen storage. The basic research will include technical contributions from the National Institute of Standards and Technology (NIST) and General Motors.

Storage is one of the main technical barriers to hydrogen fuel cell vehicles. Today hydrogen gas is compressed to very high pressures and pumped into onboard tanks, but that method doesn't match the range of gasoline-powered cars. Also, energy … Read more

U.S. government-backed battery supplier Ener1 has filed for Chapter 11 bankruptcy, the third U.S.-backed energy company to file in as many months.

Ener1 posted a notice today stating that it "has reached agreement with its primary investors and lenders on a restructuring plan that will significantly reduce its debt." This action will pave the way for up to $81 million for recapitalization, the company said.

A "pre-packaged" Chapter 11 case was filed in U.S. Bankruptcy Court in the Southern District of New York. Ener1 is planning to complete the restructuring process within … Read more

Carmakers' pursuit of fuel efficiency and sustainability is moving to auto interiors.

Ford said today that its upcoming Escape SUV will sport door bolsters made of kenaf, a flowering tropical plant. The company estimates using a plant-based material will offset 300,000 pounds of oil-based resins this year.

The door bolsters will be 25 percent lighter and so help improve fuel efficiency as well. They will be a 50-50 mix of kenaf and polypropylene and be made by Indiana-based supplier International Automotive Components.

Kenaf plants grow long stems like bamboo. The fiber can be processed into different materials, such as … Read more

Startup Oorja Protonics has dodged some of the traditional barriers to fuel cell vehicles, at least with forklifts. In the future, its hybrid approach could be used on cars and trucks, too.

The Fremont, Calif.-based company is in the process of raising funding from corporate partners to ramp up production of its product. The venture-backed company is also profitable, something that few other fuel cell companies can claim.

Rather than use hydrogen as a fuel, Oorja Protonics converts the liquid fuel methanol into electricity in fuel cells. And its onboard fuel cells are designed only to provide a trickle … Read more

Qualcomm has acquired display startup Pixtronix, which has developed technology applicable to smartphone and tablet screens.

Andover, Mass.-based Pixtronix's Digital Micro Shutter technology integrates MEMS (Microelectromechanical systems) and TFTs (thin-film transistors), providing "differentiation, while leveraging proven manufacturing equipment, processes and materials," according to the company's Web site.

Hallmarks of the technology listed by Pixtronix include low power, high-speed light modulation, Digital TFT backplane, backlight efficiency of 60 percent (a claimed 10-fold advantage over LCD), utilization of existing TFT-LCD equipment, processes and materials, and elimination of high cost, performance-limiting liquid crystals, color filters and polarizers. … Read more
