Untitled[edit]

Just because an energy source is renewable does not mean it does not produce Greenhouse gases. Biomass energy is renewable because is derived from plant matter, but the burning of biomass produces carbon dioxide.

The article also implies that nuclear power contributes to greenhouse gas emissions, which is incorrect.

Some numbers on the efficieny of compressing air using grid power to run these cars would be useful. How does it compare to the efficiency of using battery powered cars? —Preceding unsigned comment added by 129.177.48.53 (talk) 15:52, 7 January 2008 (UTC)

Technology[edit]

Assuming electricity is the same at the plug, it must be compared to the other technologies in terms of:

  1. Cost to build, cost to run
  2. Charge/discharge efficiency
  3. Power density (power over volume) / specific power (power over mass)
  4. Energy density (energy over volume) / specific energy (energy over mass)
  5. Maintenance, reliability, failure modes, etc.

The environmental impacts also need to be quantified:

  1. Emissions and energy consumption due to manufacturing
  2. Emissions and energy consumption due to vehicle operation
  3. Emissions and energy consumption due to disposal

Environmental technology template

I'd like to replace the Environmental technology template with one that matches the standard navbox style, i.e. horizontal instead of vertical, collapsing and typically placed at the bottom of article pages. I've done a mock up of what this would look like at {{User:Jwanders/ET}}. Figured this was a big enough change that I should post before going ahead with it. Please discuss here--jwandersTalk 22:03, 17 February 2008 (UTC)


Disadvantages[edit]

The article currently says "disadvantages are less well known because these engines are in pre-production phase". Then how in Hell do we know the advantages? There were several disadvantages listed a couple days ago, and they're gone, but the advantages section is intact. Both advantages and disadvantages can be known from pre-production testing, and you can't know one without the other. I'm going to revert the article, because this sounds like environmentalist agenda to me. Notice I am not going to delete anything from the advantages section.

CORRECTION: My bad, the section I saw was in Compressed-air car, not vehicle. These sound like articles that should be merged. The problem still remains, if the disadvantages are known well enough to be included in the car article, they can go in the vehicle article as well, until the articles are merged (if they are). I will copy the section to this article. Professor Chaos (talk) 20:42, 17 March 2009 (UTC)

Three mechanical engineering students from San Jose State University[edit]

The paragraph about the air-powered motorcycle built by the mechanical engineering students doesn't seem notable or well-sourced. I think it should probably be deleted. Any objections? Dansan99 (talk) 07:42, 13 March 2015 (UTC)

Yes, I'd go further and get rid of every entry that is not supported by RS, except torpedoes and fireless locos. Greglocock (talk) 10:52, 13 March 2015 (UTC)
