More About Ethanol

Here is an update to my last post about Ethanol.

Murray Dobbin's latest column on rabble.ca is entitled Last Stage Of Denial: ethanol will save us!
In the article, Murray sites more evidence about how ethanol is not the answer and will not only NOT reduce pollution, but will threaten our food sources. A quote that caught my attention from Fidel Castro: More than three billion people in the world are being condemned to a premature death from hunger and thirst ... The sinister idea of turning foodstuffs into fuel was definitely established as the economic strategy of the U.S. foreign policy on Monday, March 26th last.

The Air Car

The Air Car - zero pollution and very low running costs


Pros
- no pollution - operates on compressed air
- 1/10 the cost to operate of a gasoline car
- oil change > 1 litre of vegetable oil for every 50,000 km.

Cons
- top speed of 68 mph
- needs compressed air stations/compressors
- small production means not readily available
- to compress the air, energy is needed, so there is some pollution from whatever the electricity generation gives off

... unless of course the compressed air is produced with compressed air (which is produced with compressed air, which is...)
