Robojelly: The Hydrogen-Powered Robot Jellyfish (Video)

robot-jellyfish

What you see in the above picture is Robojelly, a robot jellyfish designed by the researchers at Virginia Tech, which could be very useful in the future for underwater surveillance or search and rescue operations. You might be thinking that there is nothing new about a robot inspired by nature, but the robot jellyfish has a new trick up its sleeve. Theoretically, the Robojelly will go on working without ever running out of energy, as long as it’s in water.

Researchers Find New Composite Material for Storing Hydrogen

Compared to gasoline, hydrogen is lightweight, has a higher energy density and has a variety of potential sources, like biomass. It sounds great, but there are a few drawbacks. Hydrogen-air mixtures can ignite with very low energy input. If air and hydrogen were to mix in an enclosed space, like a parking lot, a hydrogen leak could easily lead to an explosion if a flame was sparked. Due to hydrogen’s low energy ignition, hydrogen must be safely and densely stored.

Energy Technologies CZ a.s., small, independent research and development company in the Czech Republic announced a breakthrough in hydrogen fuel generation. According to a company press release, they’ve found a way to produce hydrogen fuel from water “cheaper” than any fossil fuels we use today; 790% cheaper than the current cost of gasoline or diesel in the U.S., and 1400% cheaper than in the Czech Republic.

Horizon fuel cell charging devices available for pre-order

Horizon

Fuel cells are not some crazy technology from the future. They’re not inaccessible to the average Joe either, because pre-orders are now being taken for the Horizon MiniPAK, HydroSTIK, and HydroFILL products. These “alternative energy charging solutions” should offer plenty of juice for your mobile devices in a greener kind of way, even if the color scheme is largely black and blue.

Hydrogen fuel cells power hybrid bus on Vancouver’s Island

Having grown up in Vancouver, I’ve already been accustomed to the majority of the city buses running on electricity. They tether themselves to the overhead lines and move the commuters around town. Over in Victoria, they’re testing something so much better. They’ve got the “most technologically advanced bus on the planet.”

Instead of relying on those overhead lines, the new hybrid-powered bus gets its juice from a fuel cell.

H-Cell 2.0 Hydrogen Fuel Cell System for RC Cars only, sorry

h-cell_04

The new fuel cell power kit for model scale radio controlled racing cars is being announced this week at the International Toy & Hobby Fair in Nuremberg. Horizon has developed an H-Cell 2.0 battery adapter kit that sits above the battery on the chassis of the car.  Quite different then the H-racer we saw a […]
