Scot, why don't we start tinkering with a Lotus Elise?
Great idea! Let's make it remote controlled!
Yeah! And radar too, let's make it into a kind of UAV!
Why don't we ditch that funny japanese engine, and replace it with a decent fuel-cell powered brushless engine?
And fit some waterscrews at the back, so we can use it as a boat!
Nah, the crappy Lotus doors would leak too much, but we can make it into a submarine.
Let's go to work!
