New concept car could possibly get 106mpg

Your title, New concept car gets 106mpg, is unsupported BS, as the article itself shows.

Next time, RTFA! :roll:

That's the idea behind the compressed air car, a vehicle its backers say could achieve a fuel economy of 106 miles per gallon.

It is possible to power a car with compressed air, but the mileage claim is "at the edge of possibility," said John Callister, director of the Harvey Kinzelberg Entrepreneurship in Engineering program at Cornell University's College of Engineering.

Another expert expressed concern about the amount of energy it would take to generate the required air pressure: 4,500 pounds per square inch, or more than 120 times the pressure inside the tires of a typical four-door sedan.

"That is above what you normally find even in an industrial setting," said William Bulpitt, senior research engineer at the Georgia Institute of Technology's Strategic Energy Institute.

"That takes quite a compressor to do. ... It takes horsepower to compress the air up to that pressure."

If you count that energy, it's hard to believe the car would be that much more efficient than an electric vehicle, Callister said.

Ok, I changed the title since one alleged "expert" is skeptical and a Cornell professor said "it's on the edge of possibility". :roll:

Something tells me you have an affinity or severe dislike for motor vehicles in general to get so mad over an article like that...

Somehow I think it'd be hard to make such an efficient car look like a Murcielago.

Would anyone here buy these? If they were proven safe, I may get one for my 30mi/day commute. It's pretty dam cheap at 18K.

At least a Lotus Elise.
 
Will never get off the ground. The oil companies will get US law makers to not allow the cars on US roads due to the dangers posed by such highly compressed gas in the cylinders.
 
this reminds me of that article about that hick with the 88 5.0L mustang that got 100 mpg and 400 hp that was around a month ago... come on now
 
Watch

They use cylinders made of carbon fiber underneath the chassis. If the carbon fiber cylinder gets punctured it just loses it's air and not explode. Since the engine is basically a piston engine using compressed air instead of gasoline you can still have pulleys on the front of the engine driving an AC compressor, alternator, etc. I think you could also have a compressor that partially refills any of the tanks as they run out of air with an isolator type setup. You would still need to have either an onboard engine that operated a compressor or be able to stop and refill the tanks. This represents a much less expensive alternative to hybrid electric cars.
 
This has been discussed many times over and over again here, for the past few years. Overall, they just update the exterior picture and move back the release date, that's all.
 
Anyone notice how ATOT attacks every alternative fuel source, while at the same time deriding our dependence on fossil fuels?

in that situation air pressure around the compressed air chamber rupture would rise quickly and then quickly equalize with ambient air pressure.




btw i love how people are so ignorant, that whenever they hear some BS story about some kind of car that runs on some kind of abundant resource (air/water) that they think its magic and will solve all of our gas problems.

in this case you would need an onboard compressor running off of a gas motor that you would need to refuel. or an electric motor in which case you would need batteries and the ability to recharge those batteries. take either of those and add the air tanks to store highly compressed air and you've got a 10 ton POS that probably cost more to maintain and run then a regular car does. And it certainly wont be more efficient.

even if you could compress the air offsite and just refil the air tanks... do you really want air to become a commodity and have to pay for air? air? really? come on folks...

With that much pressure forced out in an uncontrolled manner you could have a rocket type situation. Like hitting a air compressor tank with a ax.

 
Um FYI that compressed air is the most expensive type of utility except for maybe steam, but I think it still wins. Air compressors are not efficient.

a scams a scam, even if its a green scam.

there are many http://www.wired.com/cars/futu...gazine/16-04/ff_zapped

n/m the fuel saver addons for cars...
60 minutes even once had a show segment all about a magic shaped cyclinder head banged out by a mechanic in india that massively increased efficiency just by its shape😛 course that basically went no where.

Oh, and I can't resist... did I mention the article is full of hot air?
