I asked  asthexiancal for a drawing of me upgrading my motorike prototype. He is a mecha fan and he can put amazing details of mechanisms.

Technical data : This prototype is powered with quadricyclane (Q) and norbornadiène (N) . The heat generated by conversion of Q into (N) is transformed in current by a thermoacoustic converter. The current is send to synchronous electric motors placed in the wheels.
