Any sales process that involves haggling means the seller is a crook. Period. They are trying to sell it to you for higher than the market price, or they would just offer the market price to begin with. And then when they try to use their ill-gotten gains to make potential competitors illegal, that's just textbook… » 10/24/14 11:42am Today 11:42am

Kinda. The X-37B (the Air Force vehicle) uses hydrazine for fuel, which besides being toxic, is also highly carcinogenic. Thus the suits to keep the USAF personnel from all coming down with lung cancer. The original NASA version (X-37A) was to have used non-toxic (but explosive) high-test Hydrogen Peroxide, but USAF… » 10/17/14 11:34pm 10/17/14 11:34pm

Except hydraulic hybrids are not really cheap or efficient. High-pressure hydraulic hybrids require even more maintenance than a conventional diesel truck, and even then make a very inefiicient vehicle into a somewhat inefficient vehicle. An electric truck would draw nearly all its power off the mains (at a tiny… » 10/07/14 10:54am 10/07/14 10:54am

And where are they going to get the magical money to pay for such things? Airport authorities are always broke, and can barely keep up with things they actually need (like air conditioned jetways at PHX), let alone frivolities like preparing for tornadoes in Phoenix (that only occur every few decades). You have the… » 9/28/14 9:02am 9/28/14 9:02am

Because the RPG is travelling from much farther away. The RPG is probably launched from further than 250 meters away, thus giving the vehicle longer than 1 second to react. The vehicle only needs to be a few meters different than its projected position to miss the RPG, so it's only a few m/s2 acceleration needed for a… » 9/07/14 1:21pm 9/07/14 1:21pm

Here in Boulder, capital of the greenie-weenies (many of them flush with cash from their tech startups), the Leaf is by far the most popular electric car. I see almost as many as Priuses. The Model S is a strong second, and not much else (I might have seen iMiEV, once). So, in the microcosm of hipster techie… » 9/05/14 9:54am 9/05/14 9:54am
