The Russian Fire Hedgehog

English Russia � The Fire Hedgehog

Anyone else look at this and think "death blossom"?

During the WW2 Russian Army was using a “Fire Hedgehog” - the set of 88 Tommy-gun alike machine guns loaded into a plane. It was used at low attitude flights to effectively saw off hundreds of enemy soldiers. When the pilot got above some Nazi crowd the pilot of started fire, then the doors in the plane’s bottom were opened and this Fire Hedgehog was coming into play, eighty something non-stop firing machine guns could really look like the Hedgehog from Hell.

The $2,000 street-legal electric motorcycle

Modded electric motorcycle is street-legal, costs under $2K - Engadget

With video.

Ben Nelson's electric motorcycle manages to retain some of its original two-wheel charm while using only a penny of juice per mile -- roughly the equivalent of 300mpg. Nelson bought the bike for $100 and swapped out the original engine for a Briggs and Stratton 8HP DC motor he picked up on eBay for $500, using four $160 Optima Yellowtop lead-acid batteries for power. Nelson says he can get the rig up to a top speed of 45MPH, and he's got a range of about 20 miles before he needs to plug in -- enough to run errands around town. Best of all, the state of Wisconsin willingly registered his bike as a "hobbyist" vehicle, which means he's free to (silently) roam the streets at will.

Power assisted luggage

grinding.be -- Power assisted luggage

The PA series of checked baggage features a 12V NiMH rechargeable battery pack supplying power to the wheels when the handle is gripped and the bag is tilted. The bags weighs 10.6kg (23-pounds) which is about 3kg (6.6-pounds) more than standard hard luggage, according to the manufacture. The cases are good for about 1.5 miles of assisted travel under a 32kg load. Of interest, the bags are now 2.6kg heavier than the original case which also featured a more powerful (and possibly exploding?) Lithium Ion battery pack capable of 2.5 miles on a single charge.
