Tweel – a lame name for a cool concept

Michelin has invented the rather stupidly named ‘tweel’ – a wheel without air in it. The video in the link shows how it is mounted under a car, and has a few other applications for it as well.

The airless wheel might take a bit of getting used to, but it helps with suspension, simplifies the tyre by not needing air and a vent, damage to sidewalls becomes a non factor and no worries about whether the tyre is at the right pressure.

Car to car communication

This consortium has a whole load of car manufacturers in it trying to create a decentralised network of road cars which beam each other driving information using 802.11 built in networks. The idea is to beam information about driving conditions, accidents, traffic jams, etc to cars within a few hundred metres.
Nice idea, but how are you going to limit the spread of messages between cars from the point of interest and limit the flow of conversation? Another one, considering the ease of hacking any 802.11, is how are you going to stop people with laptops from clearing roads for themselves by injecting “road closed for construction” messages into the network from a whole host of fictitious cars?

Tesla Motors

Tesla Motors has an electric car which looks cool and has the performance to match. It does 0-60 mph in something like 4 seconds and has a range of 250 miles. As it’s electric and has no transmission, accelleration is smooth throughout the speed range. They’re trying to qualify it for road use in the US now and expect it to be sold in the US towards the middle of 2007. Unfortunately they plan on not selling it outside of ConUS. Pricing totally unkown.

Giant crossbow to shoot man 20 miles into the air

Brian Walker, mad scientist and all around crazy person, plans to shoot himself 20 miles into the air in a homemade rocket launched from the world’s biggest crossbow. The rocket, which has a jet turbine with 1,350 pounds of thrust, will shoot off the track of the giant crossbow shown above, which is equipped with a 24-foot carbon-fiber bowstring. At the peak of his flight he’ll be traveling at a comfortable 10 Gs, and he’ll be wearing a $15,000 surplus Russian space suit to stay safe, because everyone knows the Russians will sell anything for a price.

Hit Air Jackets

This jacket is like an airbag for the motorcycle. Once the cable connecting the jacket to the motorbike is disconnected, the jacket inflates pockets in the jacket with gas, protecting the spine and other areas. The gas is released after a few seconds (hopefully after the impact) allowing you to move freely again. You can then replace the gas canister for re-use, if the jacket hasn’t been totally fucked up by then.
