ask the McLaren F1 team what they had their GTR gearbox meshes made out of. You know the ones, they took the 612bhp raw engine power and reduced it from 7500rpm on the redline to 2800rpm and shoved that through the diff, thence to the wheels. Sure, you're not doing that with thermoplastic printed parts.
You'll probably find it's a nickel steel such as 300M/S155, which is extremely hard wearing and when tempered, extremely durable in high temperature/friction situations like the inside of a gearbox.
When you pour a billet of 300M/S155 into a mould and cool it (ie tempering to shape), it sets in form and becomes bloody hard - to the point where once it's set, it's actually very difficult to unform it. A bit like a binary epoxy. So where do you start?
If it were me, I'd use a low temperature wax print head and 3D-print my mould, and use that in investment casting. Thing is, with a 3D printed mould rather than a rubber form wax cast, what you're getting with the printed form is IDENTICAL moulds EVERY SINGLE TIME. You're also not having to worry about splitting your rubber cast after x number of forms. For the printer, all you have to worry about is running out of wax.
I'm aware of the foibles of the US legal system between State jurisdictions and the fact that something legal in one state is illegal in the one next door (to take the example, marijuana). Bonus that if you take a legal substance across State lines into a State where it's not legal, you fall afoul of Federal jurisdiction as well. Double whammy. Pays to know what you can carry where.
I can see an instant application for this, obviously using a lower ratio: hand winches.
Same principle as a block and tackle. For every turn of the crank, you can reduce the ratio to something like 1 in 100 and lift (theoretically) 100 times the crank load 1/100 the outer circumference of the spool. For a motor-driven winch, you could use a low voltage, low torque, high speed motor (like you'd get in a Dremel), spin that at 10,000rpm, reduce it in one of these blocks by 1/1,000 and end up with (again, theoretically) 1,000x the torque at 10rpm.
How many plants per pot? How old is each seedling before it is counted as a "plant"? I can make an aragula seed shoot in two days. I'll be harvesting in three weeks. In one square metre I can have well over a thousand plants on the go. I've done this. How many plants can I produce in a year? How many seeds ya got?
There're lots of examples of prior art local to me, if anywhere else that has a mains electricity supply, and that's pot farms.
Here, they tend to explode as people use halogen lights at silly power densities (like 6kW/sq.m) and lag the shit out of their lofts in an attempt to conceal them from police helicopter FLIRs, then wonder why they catch fire.
During the DotCom bubble, I hardly ever "slept". I used to take catnaps, probably ten minutes out of every hour. People still wonder why I have a tray of pennies on the floor next to my desk.
My first hack: built a motorised table for my mum's Singer sewing machine, came complete with foot operated beltdrive for the flywheel. My second hack: built an automatic typewriter head cleaner, which was basically similar to an electric toothbrush. It would "walk" the keys one at a time, cleaning the heads as they came up.
More recently, I've just finished building a server inside a wooden footlocker. Weighs a LOT but boy, is it ever quiet - even considering it's got five fans and five hard drives in it.
if I had an SSD instead of a spinny thing, I'd be running all swap ops on an SD card. They're dirt cheap (8GB for what, three quid these days?) and swapping out a dead one is a simple case of press until it clicks and wait until the spring ejects it. Hell, you don't even have to power down to do it.
I already use such a system on my home terminals. Everybody has their own SD card (a key, if you like) that contains their OS-of-choice and workspace. No matter which system they plug into, their dekstop and settings look identical and even if they were plugged in remotely, if there's an internet connection available they'll connect to the home shares. The exception is my laptop and my netbook, both of which have internal persistence (hard drives) necessarily because I also administrate the file services through them.
Just needed the comma, for dramatic *puts on sunglasses before heading off to the kitchen to dress a turkey and returning with a batch of freshly squeezed raisin juice*;)
and if you'd read better, you'd see that I utterly refuted that claim, as Magic: The Gathering has been going strong for two decades averaging four new expansions per year and the trade in individual cards is doing better than ever.

uh, no.

1.2 trillion per year.

a lot of dependencies in the answer:

Were you BORN that DUMB? Or did you have to sit an exam?

it's difficult to roll an office chair through rail bedding.

oh I stand corrected - the Department of the Treasury.

it's 12 in Vatican City.

They are all right, according to their own moral compasses and social norms.
no, QE is a form of fake liquidity.

I still get 0x124 bugchecks - but that's because I run the snot out of my hardware so it likes to overheat.

funny you should ask that, a Greek friend of mine just popped up and said that his local store is now accepting Bulgarian Lev.
That's left me in fucking stitches!
(before you take the piss, the Lev is tied to the Euro).
I'll wait for SystemOfADown.
I'll be here all week.

Game Gear was huge in the UK, M:TG is still going after what, twenty years?
I don't want to live in a world where I can't watch DVDs out of the box through Media Center.
