Click For Summary

Discussion Overview

The discussion centers around MDI's Compressed Air Technology systems (C.A.T's), focusing on the feasibility, efficiency, and environmental impact of using compressed air as a power source for vehicles. Participants express skepticism regarding the technology's practicality and potential as a clean energy solution.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants express doubt about the efficiency of compressed air technology, suggesting it may be a scam and questioning its viability as a clean technology.
  • Concerns are raised about the practicality of charging a vehicle to 4,000 psi, with one participant noting that it would take significantly longer than the claimed four hours.
  • Participants compare the range of the compressed air vehicle to electric vehicles, with some arguing that electric cars are more efficient and practical.
  • There is skepticism about the car's design and aesthetics, with comments on its appearance being unappealing.
  • One participant highlights the potential inefficiencies in the energy conversion process, questioning the overall feasibility of the technology.
  • Another participant notes the lack of functionality in the provided links related to thermodynamics and mileage, suggesting a lack of thorough information.

Areas of Agreement / Disagreement

Participants generally express skepticism and disagreement regarding the effectiveness and practicality of compressed air technology for vehicles, with no consensus reached on its potential benefits or drawbacks.

Contextual Notes

Participants mention various assumptions about energy conversion, efficiency, and the environmental impact of the technology, but these remain unresolved within the discussion.

After ten years of research and development of pollution-free engines and cars powered by compressed air, MDI is proud to present:

I haven't studied this yet but to me this seems an unlikely technology. This must be terribly inefficient. It even strikes me a bit as a scam - clean technology? Comments?
 
Engineering news on Phys.org
Given how long it takes a decent air compressor to charge a 60 gallon tank to 125psi going to 4,000psi should take far more than 4 hours and instead more like 4 days. And after meeting people damaged by exploding truck and tractor tires at a mere 90psi, or even unplugging an air hose and having it whip around kicking up dust, I would be hesitant to jump to using a 4,000 psi filling rig by hand.

Efficiencies and issues of generating, storing, and transferring the compressed air aside, this still seems very optimistic. 124 mile range at 60MPH that effectively puts it on a level playing field to the EV1?? My guess is that the energy density of the lead acid battery and efficiency of power conversion with an electric motor & controller should easily be able to beat this setup hands down.

Why don't we just all build a H2 fueled steam boiler? Can't imagine what rush hour would look like in the morning... :-)

No, I agree that it does not sound like clean technology. It requires electricity to run the compressor (unless it is on a hydro electric or windmill system).

I don't see it getting that kind of range either.
 
And it is a pretty ugly car too!

I think electric cars have more potential, are more efficient, practical and perhaps even better from a environmental point of wiev, if good fuel cells are developed. However there must come something good out of this research too. Perhaps in a couple of years...
 
Unless I'm really missing sopmething, it looks like total BS.
Just do a simple compressed ideal gas energy conversion, this
thing certainly can't propel a car to any reasonable distance,
let alone 200 km. And if you compress the air using a chemical
engine then you've gained nothing and just got more efficiency
decrease of the whole thing, let alone converting chemical
energy into electricity and then into the compression energy.
French people... :biggrin:
 
That car is uglier than the Honda Element. And that's one ugly car. If you ask me feul cells are the wave of the future.

Note that the Thermodynamics and Mileage link doesn't work at the home page. http://www.theaircar.com/howitworks.html

It is getting plenty of press. I wonder if we aren't going to have a lot of egg on the faces of technical editors, sooner or later.
