$1.5M?
Can anyone really design and build an aircraft like this for no more than $1.5M? They'll probably cost that much to buy one.
I would hate to run out of biogas in mid-flight.
US space agency NASA has announced a competition for green aircraft designers, in which low-carbon flying machines will contend for a $1.5m prize at a contest to be held in California in two years' time.

It seems to me we are just talking about gliders with enough power to take off to a suitable altitude here, as such one would expect them to be extremely quiet once airborne. Even if this is not the case, noise is just escaping energy, therefore any vehicle that wants to be as efficient as possible must as a part of that efficiency drive reduce noise...
Oh yeah, and I'd rather run out of biogas in a glider than a flying car! ;o)
