Robotic Jellyfish For U.S. Navy Powers Itself With Seawater

Manufactured from a mixture of silicone and varied high-tech supplies, the Robojelly uses oxygen and hydrogen gases in seawater to set off a chemical reaction that causes its synthetic muscles to contract. The muscular motion copies that of the moon jellyfish, which permits water into its “bell” after which closes the bell to push the water out and create a jet that strikes the creature along.

All-wheel drive means all-wheel fun on dry days because it spreads the automobile’s energy by way of all four wheels. That means the automotive can shift power to the wheels that want it via the curves. On the R8, up to 35 % of the power will be shifted to the entrance wheels, giving it better grip irrespective of the weather.

If all this talk of being “mild” and “quick” appears type of imprecise, let’s put it into perspective. The 2004 Porsche Carrera GT boasts over 600 hp, but it surely weighs in at about 3,200 lbs (1,450 kg). That’s greater than a half-ton heavier than the Elise. Even an Enzo Ferrari, with 650 hp, is a heavyweight at 3,200 lbs (Motor Pattern, Oct. 2004). In a straight-line run, that horsepower would put the Elise to disgrace when it comes to prime pace. However on a tight, twisting highway course, hydraulic motors manufacturers the $40,000 Elise could outperform cars that cost a whole bunch of 1000’s of dollars extra.

For optimum driving vary, a “regenerative” characteristic reversed the main motor on braking to exchange some of the ability used; a transaxle “coastdown” characteristic gave a similar impact when coasting on flat surfaces or when or descending hills. Recharging was by a 220-volt stand-alone unit or a 110V onboard charger. Recharging took 12-14 hours with the onboard unit, about three hours with the 220V equipment.
