Vapman is a conduction vape, the mica got nothing to do with convection at all, this is a myth a reseller put in the world years ago. The mica shielding is a protection for the wood, even it reflects the heat better than the plain wood, it has nothing to do with convection.
So, it was 'on the web'? Must be true. How can you possibly say otherwise.........
A place I worked at years back had a real us/them thing going between Production and Sales. Sales (AKA 'the suits') could only sell stuff we couldn't make. We were making, among other things, a shipboard RADAR tracker (for anti collision, not easy when it takes 15 minutes to do an emergency right angle turn......). It used two knobs, one for the bearing of the ship you wanted to track, the other for the range it was from you (polar system, like the RADAR sweep you see in movies). But the military versions (that cost 20 and 30 times more....) used trackballs to move a cursor. Real sizzle at the time. Very hard to do 'on the fly' with the then available state of the art 8086 processors (we already used 3).
So I get the duty to move a completed unit to the Photographers for flashy brochure photos. Takes hours, very fiddly, I hated the duty. This time was different. We did the usual glamor shots (lots of Polaroids and lighting shifts, dusting and such). About the time we were ready to pack it in (I thought) and asked if I should have the guys from the shop come back with the truck, the OM (Old Man, owner) turns to the Graphic Artist (yes we had one full time....) and as 'did you bring it?' She said yes, and produced a shoebox with half a tennis ball painted black. Seriously. They'd scrubbed the fur off somehow and painted it black but that's what it was.......until it hit the panel, when it became a trackball.......
I freaked out, as you might imagine, having been part of the meetings were it was discussed in great detail how difficult it was, how expensive and how many pitfalls there might be. The OM looked at me, smiled, and said 'but we've already sold two of them.....'.
And he was right, it was on the new sales brochure. Which came out not long after, and about two years before we finally made it happen. By then we'd sold a couple more of course. Never worked well, overheated on hot bridges (not all have AC, not all of that works right all the time). Because we didn't Beta test well we didn't find out until we'd installed a dozen or so. We had to meet every one of those ships where ever they made port long enough to go aboard, cut holes for four fans in the back and vents under the toeboard in front. Very expensive way to do business. But popular with suits......who are only after commissions.....
Sorry to ramble, but it's a fun memory.
