Firing the Lorentz Plasma Cannon
LightningOnDemand

LightningOnDemand revives a pulsed Lorentz plasma cannon, using modern capacitors to extend its range and increase the delivered energy. It is a high-voltage, high-current hobby demonstration.
HN users suggest it to anyone who enjoys extreme high-voltage projects and big capacitor-bank discharges.
