I fondly remember watching him on the TV doing those demonstrations. I was lucky enough to attend some of his RI Xmas lectures. In one of them he could easily have shot a member of the audience with an electromagnetic gun. The projectile - a substantial metal rod which I think was made of alternating bands of copper and iron was fired at a thick target of multiple sheets of blockboard with audience members behind it. The projectile penetrated the full thickness of the target but fortunately remained wedged in it. John |

I never did actually see the damage but a lot of people were talking about it. |

Hmm, you do get a force when you flip a gyroscope. Whether you can harness that force to give continual movement in a particular direction is the problem. Its not as though he was trying perpetual motion like most cranks out there. |

Whether you can harness that force to give continual movement in a particular direction is the problem. Its not as though he was trying perpetual motion like most cranks out there. I wasn't being critical of him, but rather critical of the 'establishment'. He was/is one of my tech heroes, ever since I saw him on the Christmas Lectures and the Open University. |

Lonely Psychotic Senile Ozzie Troll Alert! LOL
On Tue, 4 Dec 2018 05:03:58 +1100, cantankerous trolling geezer Rot Speed,
the auto-contradicting senile sociopath, blabbered, again: I fondly remember watching him on the TV doing those demonstrations. Striking how much better the video quality is now even with the cheapest phones. Striking how you REALLY keep following up on EVERY SINGLE link that will get posted here, you useless senile idiot! G -- Bill Wright to Rot Speed: "That confirms my opinion that you are a despicable little ****." MID: |
