The sport of drag racing has been with us almost as long as the automobile has.
Over the last decade, advances in high-power lithium-ion batteries have given rise to a new variant: electric drag racing.
But before modern batteries existed, how could you possibly make a competitive electric dragster?
Well ... how about with a monstrous Allison V-12 engine, a generator, four starter motors for jet engines, and two spools of thick, high-capacity electrical cable?
That's exactly what drag-racing legend E.J. Potter (aka The Michigan Madman) built in the late 1960s, as detailed in a 2012 story on The Kneeslider.

He called it "the Super Slot Car," after the (now largely-vanished) sport of racing tiny electric model cars around a grooved track.
Potter had previously created a series of drag-strip motorcycles known as "Widow Makers," for their Chevrolet small-block V-8 engines mounted in Harley-Davidson frames.
He dragged the bikes for 13 years, eventually reaching 190 miles per hour and setting a Guinness World Record in the process.
But after some injuries, he turned his attention to the idea of blinding acceleration without internal-combustion engines.

He attached an Allison V-12 airplane engine to a generator, and mounted the assembly on a trailer, along with two large spools of electrical cable.
When performing at drag events, he'd unspool the cable down the quarter-mile length of the drag strip.
A natural-born showman, Potter took his time (about 3 minutes) in driving his pickup down the track to unspool the cable, and then firing up the massive Allison engine.
The Super Slot Car itself was the stripped shell of a small MG 1100 front-wheel-drive two-door sedan, with four 200-horsepower electric jet-engine starter motors, one per wheel.

Two electrical pickups on the bottom of the car carried electricity to wiring that distributed it to the four motors--just how a slot car works (with fewer motors).
The car's lettering even said "Smog Free Performance" on the trunk.
After the crowd was fully engaged, Potter would just flip a switch--sending his car rocketing down the track at triple-digit speeds.
The Super Slot Car reportedly ran the quarter-mile in the low 10-second range, with a trap speed of 120 mph. Not bad for half a century ago.
Potter never found a sponsor for his unique concept.

He later blamed hot-rod magazines for a lack of coverage, saying their publishers didn't want to antagonize advertisers selling parts for conventional gasoline-powered drag cars.
Potter died at 71 in April 2012; an obituary in The New York Times not only mentioned his "Michigan Madman" moniker but eulogized him as "a legend of the American drag strip."
As Left Lane News noted in a cover of the story, "Today, though, the burgeoning electric drag racing community considers Potter to be one of their pioneers."
