Green Electric Cars

OK, maybe they haven't been perfected yet, I don't know, but here are some more links...

According to some sources, they have much better mileage than gasoline vehicles. (Air Cars can travel 200 kilometers for just 1.5 euros)

one of a handful of planned Air Car models, can hit 68 mph and has a range of 125 miles. It will take only a few minutes for the CityCAT to refuel at gas stations equipped with custom air compressor units; MDI says it should cost around $2 to fill the car’s carbon-fiber tanks with 340 liters of air at 4350 psi. Drivers also will be able to plug into the electrical grid and use the car’s built-in compressor to refill the tanks in about 4 hours.

achieves over 100 gas-equivalent mpg and over 90 mph, has zero to low C02 emissions,

And after I leave the driveway?

Jesus fucking christ, 4350 psi! Have you any idea how dangerous that is?

Hey, but they are safer for the environment. I wonder if we can get some hydrogen powered cars on the road soon. Can you imagine the fireball after two of those babies run into each other?

Compressed air tanks for paintball guns can run in the 3000-4500psi range. Granted they are around 68 cubic inches, not 340 liters. Minor detail really.

I saw a video the other night of some kid who was killed when one of the paint ball canisters failed. A bit blew off and hit him in the neck.

Sounds like he may have had a faulty burst disc. It's a little piece of safety equipment installed on all compressed air and co2 tanks that is designed to fail when the pressure inside the tank becomes dangerously high, releasing the gasses from the tank quickly and preventing a hazardous over-pressurization. If that malfunctioned and did not fail as it was designed to, then some other part of the tank must have eventually succumbed to the over-pressurization and catastrophically failed, sending pieces of the metal or fiberglass tank flying at high speed no doubt.

Paintball is a very safe sport if safety guidelines are strictly adhered to. All you may end up with at the end of a hard day playing are some bruises/welts and minor scrapes from crawling and sliding around on the ground. When players and field operators/owners/refs neglect their safety equipment like facemasks, barrel blocking devices, gas system, etc., serious injuries, and in this case death, can and do occur. That said, this could have been entirely not the kid's fault. Could have been a cheap tank, not hydro-tested recently, or the fill station operator damaged/overfilled the tank placing this kid in harm's way. I will definitely encourage my future kids to play paintball. It's an exciting, physically demanding, team-building sport that is statistically safer than many other popular sports when safety standards are adhered to.

I have no idea what it even means. I am stupid about the mechanics of cars. Explain to me please why it is dangrous. Thank you.

I watched this show on NOVA last night about the cars of the future. It was very interesting. http://www.pbs.org/wgbh/nova/car/

It is just a discussion about taking a potentially flamable glass and putting it into a container under great pressure. PSI = Pounds per square inch.

The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/in² or lbf/in²) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch:

1 psi (6.894757 kPa) : pascal (Pa) is the SI unit of pressure.

Gases or gases in a liquid phase which become pressurized are potentially more dangerous in that state than at atmospheric pressure.

Is compressed air a gas then?
