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 Friday 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.

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
