“Do you have a minute?” Jessica asked Elon Musk the next morning. 

“Actually no but make it brief,” Her boss replied.

Jessica had already spread the blueprints and material specifications on a conference room table while Elon Musk was still snoring on its couch, exhausted from yesterday’s world-saving.

“Dammit. I’ve never seen anything quite like this, but it reminds me of the supercapacitors back in Stanford. Back then I was sure they’re gonna save the World…”

“Partial credit.” Jessica was pleased to note that Her boss was on the map. “But look closer at this.” 

She pointed Her delicate finger at a detail magnification between the thin alternating foils that made up the capacitor’s cathode and anode. “What do you make of this?”

“Looks like some kind of a dry-cell battery. Wait a minute… Are you telling me…”

“…that by making the capacitor’s electrolyte into a battery with these specs, you can store about four kilowatt-hours in a one-kilogram battery,” Jessica interrupted. “Yep, that’s what I’m telling you.”

“That’s like twenty times the energy density of the current Tesla batteries. If that’s true…”

“It’s true all right. The more important question is: can you manufacture it?”

“Sure. We’ll have a working prototype in three days and full-scale mass production in… say two weeks from now. I’ll tell my engineers to stop wussing around and do something for their salaries. Say… could you arrange half a dozen hammocks here in the conference room? The guys won’t sleep at home until the line spits out a hundred thousand of these babies an hour. 24/7.”

“There’s still the other question,” Jessica interrupted Elon Musk who was already on his way out with the plans, completely forgotten what he had initially planned for the morning. 

“Which is?” asked Elon Musk, eager to get out of the room.

“We must open-source this,” said the thick-lipped Viivi Pumpanen -lookalike. “Our ethical guidelines prohibit us from providing any competitive benefit to a single company. Anything that’s done in God’s name is by definition public domain.”

“Tell that to Jehova’s witnesses,” Elon Musk grinned. “Or Catholic priests, for that matter.”

“Is that OK with you?” Jessica insisted. “Can the design be signed by some Tesla engineer and then be set out in the public domain?”

“Yeah, yeah, do it. Send out a tweet,” said Elon Musk and fled the room with the divine paper rolls.
