**The main issue with zero-emission cars seems to be 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.

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
