It already takes a few hours for each process, even with speeding it up it’s unrealistic. Possibly just build the onion’s skeletal features, it’s cooling coils, and then apply the foil layers by hand. Or spray them onto it. Or more likely spray the insulator, and layer the conductor.

Our pleasure, Aaron. Got a revised sketch at http://energymadecleanly.com/anode1.pdf

Henning, the biggest single challenge of building onions in any quantity is going to be to get an indexing drum within a 2 powder laser sinterer or 2 material CVD machine without ‘overspray’. Given a mochine that can do that, we put several thousand of them in the 2M sq ft Government Motors plant up in Grand Rapids that Brian, Rematog, and I were discussing about a year ago. No reason not to build on the east side of that building and prove along the west side, away from housing and traffic, but closest to those 6 regional transmission lines that we could tee into 12 lines by putting transmission transformers in the west parking lot.

Given the state of the art as I understand it, we’d need to put several thousand CVDs shoulder to shoulder, passing off in a continuous series of vacuum locks without losing registration or browning out that part of the city.

Keep your eye on the toolmakers’ trade shows. No telling what we get for Christmas this year 😉
