clipper's remarks: Eden Energy, through its wholly-owned U.S. subsidiary Hythane Company, has announced it has received a U.S. patent for its cryogenic storage vessels for liquid hydrogen. Among the applications, the new technology will advance the practicality of hydrogen cars by optimizing energy storage, reducing or eliminating the need for bulky lithium ion batteries.

The main use for this technology, called Superconducting Magnetic Energy Storage (SMES), will be in the automotive industry. Whether used for traditional hybrids, electric cars, or hydrogen combustion engines, SMES will capture and use energy from the vehicle braking system to reduce or eliminate the use of large, expensive batteries. By combining fuel storage and the battery into a single unit, the range and efficiency of alternative fuel vehicles will be increased, and fuel can be stored in a much smaller space.

Biofuel: Major Net Energy Gain From Switchgrass-based Ethanol

ScienceDaily (Jan. 14, 2008) — Switchgrass grown for biofuel production produced 540 percent more energy than needed to grow, harvest and process it into cellulosic ethanol, according to estimates from a large on-farm study by researchers at the University of Nebraska-Lincoln.

clipped by: Kauaiguy
clipper's remarks: First practical way to motorize your bicycle.

Clip Source: www.revopower.com

25cc two-stroke engine; 1 HP or 0.8 KW power maximum output at 7500rpm;

The Wheel is driven by a series of sprockets & chains which drive the engine (and the wheel) around a fixed axle

20 mph (32 kph) over flat terrain; normal bicycle brakes are sufficient to stop it

Standard two-stroke fuel (a mixture of normal gasoline and oil)

Over 100 miles per gallon

Less than 15 pounds (5 kg); 12 pounds net of additional weight once the original wheel is removed

Less than 65 dB at a distance of 7.5 m; very quiet operation

Extremely low; using the latest technology, it meets EPA and CARB regulations; The Wheel stops when you stop, eliminating idling and emissions caused by idling

Automatically engages when engine is running

Single user interface of throttle and starter; User must pedal to start the motor; no idling possible

clipper's remarks: I'm sure these cars will be popular in Europe, Japan, etc.. I don't think they'll take off in the U.S. until gas is $25 a gallon.
