We may be closer to harnessing the power of the sea and air. The world's first hybrid wind-current power generation system will be installed off the coast of Japan later this year.

The Savonius Keel & Wind Turbine Darrieus (SKWID) power generation system being developed by Mitsui Ocean Development & Engineering Company (Modec) is a floating system that shares a vertical floating axis. On the company's Web site (PDF), Modec says the concept will generate double or more power from the same sea surface area as a conventional wind turbine. … Read more

When you pedal a bicycle, the kinetic energy is channeled into propulsion, but what if it could be used in other ways? Architect Michael Strain isn't the first to think of using pedal power to charge your gadgets -- in fact, there are products on the market that already allow you to harness that excess energy -- but his concept bike, has a few other tricks up its suspension.

The bike, called Levitation and designed for the 2013 Hi-Macs Annual Design Contest, looks like a more low-tech Tron Cycle. It features an on-board generator and battery that stores the power collected while cycling. The power can then be used in two ways: charging small gadgets via the USB port on the bike's handlebars, or sending it into your home's power supply via a drain cable to alleviate grid usage. … Read more

Tesla, the electric car maker, has been in talks with Google about the development of a self-driving car, the former's CEO revealed Tuesday.

In a Bloomberg interview, Tesla CEO Elon Musk said that his company has "had some technical discussions with Google" about the search giant's self-driving car technology. However, he pointed out that the technology that Google uses, which is based on laser sensors to detect what's around, is too expensive to be feasible anytime soon.

Instead, Musk told Bloomberg, he'd like to see a camera-based system that "sees" what's … Read more

Following a bicycle down the runway at Moffett Field in Mountain View, Calif., a solar-powered airplane took off on a coast-to-coast voyage across the U.S. this morning to promote the message of clean technology.

Piloted by Swiss aviator Bertrand Piccard, the Solar Impulse HB-SIA set off for Phoenix, Ariz., on the first leg of its Across America journey that will also take the slender craft to Dallas, St. Louis, Washington, D.C., and finally New York in early July.

The goal is to go from one end of the country to the other without using a drop of fuel. … Read more

Kitchen showrooms are full of massive, shiny appliances meant to be strewn liberally about in a large kitchen. Most of the world, though, doesn't have that kind of space to spare for ovens, microwaves, refrigerators, kitchen islands, stovetops, and the like. The Clei Ecooking kitchen minds its manners and limits itself to a very compact space.

The Ecooking station is sleek, modern, and modular. It was created by Italian designer Massimo Facchinetti for Clei, a company specializing in transformable furniture. The company's creations are intended to make the most of small spaces like apartments and lofts.… Read more

Humans have a lot in common with magpies. We gravitate toward shiny things.

It's easy, then, to see why the Glowing Plants project on Kickstarter has more than doubled its goal and still has 38 days to go. It's a fascinating mix of botany, science, and unexpected glowing things.

Some people can boast a green thumb, but very few people can boast a glowing green thumb. For a pledge of $40, Glowing Plants will send you 50 to 100 seeds to let you raise your own glowing plant at home. The project's creators say that this is a one-off opportunity and the seeds will not be available commercially later on.… Read more

Tesla announced today that it would offer its high-end Model S Performance edition, with an 85 kilowatt-hour battery pack, and the Roadster as loaner cars for when owners' cars are being serviced. As Tesla sells cars directly to owners, the company, rather than a dealer, handles all service and loaner-car issues.

No matter what Model S version is in for service, owners will have their choice of the Model S Performance edition, which retails for $87,400, or one of the older Roadster models as a loaner car. Further, Tesla said it will let owners who would like to upgrade … Read more

The last time I'd found myself astride an electric bike was over four years ago, when CNET reviewed the Schwinn Tailwind in March of 2009. That bike was jerky and awkward, very heavy, and a bit of an eyesore.

Fast-forward just under half a decade to April 2013, when I find myself standing in front of the sleek, red frame of the new Specialized Turbo. Electric bike, you've come a long way, baby.

Design The Specialized Turbo is a good-looking bike. Period. And I don't just mean "good for an electric bike."

The bike blends … Read more

There's the possibility that Tesla may be looking to make its luxury all-electric cars a tiny bit more affordable. The company's CEO Elon Musk tweeted Thursday that Tesla will announce some big news on Friday.

Announcement of new @teslamotors strategy tomorrow. Tesla owners will like this.

While no further information is given, this tweet does offer some clues into what Musk may be suggesting. The fact that he mentioned it will be something "Tesla owners will like" harkens back to a similar tweet from last month.

After tweeting about an … Read more
