You don't want see the elementary facts then invent ridicoulus and very expensive for us conditions.
Then why with your hallucinatory thermal theories don't reply elementari facts :
with Asps PNN (with batteries .. and remote control) if on a scale we have thrust in a direction ... at 180 degree we have rotfl thermal ANTI thrust :-)
we repeat this many times :-)
so you must invent and DO something of realistic to explain such MANY facts ................. such the follow two days ago : With more than 15 minutes of power Sub321n4 reach on scale more than 20 grams of thrust ... reproduce this this "thermal effect" with a coax cable that power a dummy load :-))))
the pnn only needs time to take off and of course an adequate system of solar panels. The thrust curve is similar to this
All newtonian and realativistic theories are comic and have no meaning in the PNN field :-) www.asps.it/pnnsubitam.htm
