Severe injuries from road accidents = 36,000 jumbos crash landing {{em}} this is reality of road transport. Likelihood of being killed on the road is something like 1 in 200 (need to find ref). Number one killer of young people [http://www.who.int/mediacentre/news/releases/2007/pr17/en/index.html] and by far the leading cause of accidental death [http://www.notsoboringlife.com/ramblings/top-10-causes-of-accidental-death/].

* Land use in cities. Roads cover a huge percentage of urban land (need to find figures, probably about a third). A more space-efficient transport network (like PRT) would allow for more greenery

Electric/fuel cell vehicles are finally catching up with the performance of petrol cars. The Tesla Roadster proves this: cheaper to run than an ordinary car, 125mph top speed, 0-60mph in 4 seconds, 244 mile range, 3.5 hours to charge.
+
 
+
The main issue is [[Energy#Storing_energy|energy storage]] - how do you store energy in a way that's as dense as the caloric energy in petrol? Batteries? Ultracapacitors? Flywheels? Fuel cells? Compressed air? A combination of these? Batteries have environmental issues of their own, and need to get lighter. Ultracapacitor technology is getting better, but still is nowhere near the density of petrol; nanotech will help here. Fuel cells have high energy density; ultracapacitors have high power ddensity, so perhaps a hybrid (like the one Riversimple are working on) is the most promising.
+
 
+
The other issue is energy efficiency. Regenerative braking technology is now pretty good. Carbon fiber is 4 times lighter than steel and 5 times stronger. It is 14 times more expensive, but you would make that back in fuel costs coz it's lighter. Carbon fiber is progressively getting cheaper and being used more and more in cars. Third generation photovoltaics in windows and paint will allow cars to produce their own energy on-the-move.

Cars

Financial cost of road traffic accidents estimated at over $120 billion in the US and over $193 billion in the Europe Union. (Found in slideshow from Delphi Automotive Integrated Safety Systems - need to find source).

Efficiency

Third generation photovoltaics in windows and paint will allow cars to produce their own energy on-the-move. The roof of a car can hold about 1m2 of solar cells, which might receive a thousand watts a day.

Driverless cars

Center for Automotive Research Stanford (CARS) doing a lot of work in this area, including cars that are driven by humans, but have smart systems so they "cannot crash"

Aviation

  • The "Green Flight Challenge incentive" is a prize of $1.65m for electric planes that get 200 passenger-miles per gallon equivalent or better. This is about 4 times more efficient than a typical plane.
  • http://www.synergyaircraft.com
  • The Skylon spaceplane, as well as making speaceflight cheaper, aims to fly from anywhere to anywhere in less than 4 hours.
  • Personal aircraft. These will be needed or areas not served by road or rail. Persona helicopter travel has been the exclusive preserve of the mega-rich, but in an era of open-design + digital manufacturing, there is no reason why this should continue to be the case.
    • Flying cars 11px-Wikipedia_logo.jpg. VTOL would be best.
    • FlyNano is a 70kg personal flying machine with an airspeed of 140km/h. Can be all-electric. Being sold for just €27000, released later in 2011
    • Autonomous helicopters already exist like this mini-helicopter designed at MIT. Hummingbird Unmanned Rotorcraft is autonomous and has a much better fuel-efficiency than any other helicopter and also goes at a higher altitude, which would be better for solar power. Other unmanned helicopters include the RQ-7 Shadow. Bell Eagle Eye is an unmanned tilt-rotor vehicle.
  • Sub-orbital passenger craft
  • Free flight
  • Skycat - a hybrid airship/hovercraft
