The Lightning Foundry by Greg Leyh — Kickstarter via jwz.

What is the Lightning Foundry?   The Lightning Foundry is a project to re-create super-long discharge effects normally found only in lightning.  Two 10-story Tesla Coil towers will fill an area the size of a football field with lightning-like discharges hundreds of feet in length. If we trigger super-long discharge effects the arcs could strike considerably further.

Wow! These folks get our Tesla coil badge once we get them in stock
