Compressed air cars

By Murray Bourne, 11 May 2006

There are 2 very promising inventions that use compressed air as the energy source. The first, from France, drives a piston engine (which does not require any ignition of a carbon-base fuel).

Di Pietro engine
The second, which seems more promising, is from Australia and it drives a light (13kg) and simple rotary engine.

The compressed air is held in tanks made of carbon fibre. Why? If the tanks are damaged in an accident, a metal-based tank would explode and cause a lot of damage. Carbon fibre will split and cause little damage. besides, it is light and very strong.

This is a small vehicle powered by the Di Pietro rotary engine.

The current high price of oil means these alternative energy source proposals can get a serious hearing - and the oil companies have less impact on the US & other high polluting governments.

There is more info on similar engines at Quasiturbine.

Bring on the alternatives to gas guzzling cars!

HTML: You can use simple tags like <b>, <a href="...">, etc.

To enter math, you can can either:

  1. Use simple calculator-like input in the following format (surround your math in backticks, or qq on tablet or phone):
    `a^2 = sqrt(b^2 + c^2)`
    (See more on ASCIIMath syntax); or
  2. Use simple LaTeX in the following format. Surround your math with \( and \).
    \( \int g dx = \sqrt{\frac{a}{b}} \)
    (This is standard simple LaTeX.)

NOTE: You can mix both types of math entry in your comment.
