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[edit]

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)

Forest as a habitat[edit]

The head paragraph, stated a forest as something that the ethic is trying to preserve. Conservation doesn't strive to preserve forests. Conservation strives to conserve the natural processes of life, INCLUDING if a forest were to change into a swamp (for example) as long as humans didn't have anything to do with it. --FUNKAMATIC ~talk 18:19, 11 January 2010 (UTC)

WARNING (to the editor): There are some problems with the added paragraphs in the introduction: >>> 0px|High energy advertising in Shinjuku, Japan.]] Text is incomplete at the end: "Energy conservation is often the most economical solution to energy shortages, and is a more e" — Preceding unsigned comment added by Iwnit (talkcontribs) 06:21, 13 January 2010 (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)
