Fuel cells are amazing things but, just like any portable energy source, they occasionally need topping up with juice. This one, however, can keep on going even when it runs out of fuel. What kind of sorcery is this?

Tomato juice, Bud Light, home electronics—is there anything clam won't work well in? Everybody's favorite bi-valve is now an essential part of an experimental engine—it's the battery.

The idea of using insects and other small creatures as data-gathering devices has always been hampered by the need for short-lived external batteries. But what if you used the animal's own metabolism to continuously power their sensors?

Fuel cell outfitter Horizon is now offering a personal hydrogen power plant for use with its MiniPAK and HydroSTIK products. Although it isn't cheap, the system will (cleanly!) charge all of your small devices using the same water you drink.

In today's Remainders: things lurking below the surface. Literally, a fuel cell-powered fish. Less literally, ISP's seething contempt for the FCC's new National Broadband Plan. Also: Samsung's David Lee Roth tablet love and a helicopter with rocket-powered blades. Yikes.

The Bloom Box is the latest energy miracle that sounds too good to be true: Debuting with a wide-eyed segment on 60 Minutes, it promises to be clean, cheap and backyard-friendly, the solution to our energy problems. What is it?

As mentioned last week, Toshiba's first batch of 3,000 direct-methanol fuel cell (DMFC) chargers—the first from a major manufacturer—hit Japan on Thursday. The IDG News Service has been testing one, and here are their first impressions:

The Dynario fuel cell charger from Toshiba will launch in Japan on Oct 29, bringing with it direct methane fuel cell injection that lets you charge two cellphones simultaneously.

Sony's new concepts for fuel cell batteries come in some interesting flavors, like these speakers-with 70s transistor radio look-that can recharge your phone or multimedia player. Or the fuel-powered, completely-wireless, coffee maker-looking home theater speaker.

Chemical engineers working at the University of Illinois at Urbana-Champaign have developed a hydrogen fuel cell that measures only 3 millimeters across. That could mean longer lasting, eco-friendly power for your gadgets.

Congressman Eric Massa of NY tried to drive a fuel cell car from NY to DC to make an environmental point and to show how great fuel cell cars are. He failed at both.

This has been years in the making, but it seems we will be able to get our own fuel-cell-based USB charger by the end of 2009. I still wonder if the FAA will allow these.

The original Horizon H-Racer hydrogen fuel-cell toy just got an update: Before, you could fill it with water and let 'er rip. Now, you can actually steer the bastard.

Panasonic's latest fuel cell breakthrough is the world's smallest designed for notebooks—270cc, about the same size as the existing lithium ones. They use highly concentrated methanol, similar to ones designed for the military as the fuel source, though 200cc of juice will give you 20 hours of power—or a whole one…

Scientists at Korea's S&P Energy Research Institute have worked out a way of manufacturing hydrogen that's 20-30 times cheaper than current methods. Typical electrolysis methods in use take about 4 to 4.5 kWh of energy for each cubic meter of H2 gas but the new Korean method (apparently a chemical process) takes just…

I'm all for hydrogen-or any alternative fuel source for that matter (Shai Agassi, my man, let's get cooking already!)-but if you're going to heavily promote your cross-country trek as the "first ever" for hydrogen-powered vehicles, at least make sure large, 1,000-mile stretches of it did not involve having the…

Horizon Fuel Cell Technologies have launched the the Bio Energy Discovery Kit, a product that they are calling "the fuel cell industry's first direct ethanol product." The kit directly converts alcohol into electricity and can run non-stop for days on end. The purpose of the kit is to introduce fuel cell technology to…

Australian researchers have developed a new fuel cell prototype that could lead to much cheaper, more efficient fuel cell vehicles in the near future. Scientists at Monash University in Melbourne created a new cathode that could bypass the need for expensive platinum nanoparticles, which adds about $3500 to $4000 to…

Oxygen and hydrogen are both excellent energy sources, and we've got tons of both on Earth. Unfortunately, that energy is mostly tied up in water molecules that require still more energy to split apart. But what if you could split water molecules with a modest electric current, under conditions you can duplicate on…

Part giant Segway, part car, part Tron light-cycle, part whirling glass-walled deathtrap...think of it as you will, the Ozone is actually a pretty interesting concept vehicle designed by Ozkan Koral. Accessed by rotating doors within the wheels, the passenger cabin is actually inside the wheelbase. It's powered by…
