A while ago, I was commissioned to design something called a "Mana Turbine". It was supposed to be a machine somewhere on the level of a hydroelectric generator, but it used the directed flow of "Mana", or life-force, to generate electricity. Since I wasn't given any guidlines besides that, I decided to be a bit fanciful and go for the trilateral design, just because I thought it was perty. Given the integrated catwalk encircling the main enosculation-chamber, it's fairly easy to tell tell that this bad boy is over 3 stories tall and around 40 feet wide at it's greatest diameter. This thing weighs in at over 45 tons.
Also, this WAS a commission piece that has yet to be paid for. My commissioner has recently decided to flake, given that he has stopped responding to any of my messages. While this is easily copied, it isn't in the desired delivery format.
Also, remember, this is İDoomsday-device, so don't touch it.
