Fuelless Flight with Air Submarine?

Posted by michael on from the in-this-house,-we-obey-the-laws-of-thermodynamics dept.

An anonymous reader writes "Using the same physics principles as submarines, a new company is planning a fuelless air ship. Recent advances in ultra light and strong materials are making this concept a practical reality." There's no question that changes in buoyancy can be used to propel a vehicle, but "fuelless" is going to be tricky.

    Apparently, these people have never heard of the Second Law of Thermodynamics...or, in layperson's terms, "The Idiot Filter."

    How is that informative?

    " a trillion trillion trillion gallons of fuel" ? WTF? AV, are you REALLY telling me that dev costs are going to be equivalent to the cost of 1 x 10^36 gallons of fuel?

    Yet again, Amsterdam Vallon posts some useless crap, follows it IMMEDIATELY with a A/C post asking for a "+1, Informative" - and some fool obliges.

    Gentlemen: use your own sense of perspective. There is nothing insightful or informative about this post. It is factually incorrect, and is pointless. If you happen to notice that some less-than-perceptive moderator has succumbed to AV's weak attempt at karmawhoring, please use your own points to correct the problem.

    Thanks.
