There is not really a thread for R&D so I will post some interesting news here. You all may have seen a few posts here from a lady named Sebbie. I was allowed to see a demo of a prototype system she was working for her Masters degree. Its a gasoline powered machine gun. Actually its a slaved manifold gun to a gasoline engine. No brass, no powder, no primers. She used it to cut an old telephone pole in half in a mater of seconds. I am not allowed to show pictures until all is patented. Its a brilliant concept. Her idea is for ground support aircraft. More projectiles, less weight and logistics. The thing spits bullets at a furious rate of fire! Its nice to be related to a genius.
