First, the radial-engined motorcycle built by Jesse James. What's even cooler-but-crazier, if you read the comments on this article about an alternate take on the radial-engine concept, some guy (see the second comment) is thinking about building a motorcycle with a rotary¹ engine. Not rotary as in Wankel; rotary as in WW1 rotary aircraft engines, where the entire cylinder array spins around a fixed crankshaft.
And, for a different kind of cool just because it's such outrageous snake oil, check out the miracle hydrogen-power solution to the world's energy needs from the guy who's invented the "very unique¹ elecrolysis process" that turns H2O into the magic wonder-gas HHO. Just think, if he used his wonder-gas to run a generator to drive his electrolysis machine, he could have a perpetual motion machine!
(....Not.)
[1] Dammit! I used the word 'rotary' three times in this post. And each time, I consistently typo'd it as "rotaty". And somehow I only spotted ONE of the three typos each time I checked it........ each time I fixed one and glanced at the others to make sure I'd got them right, the others looked OK.
[2] Last I knew, the formal definition of "unique" was something like "there exists precisely one such". Does something that's "very unique" use a smaller than usual value of "one"?

1) It ain't running off water, it's running off electricity. "HHO gas" is just a way to make a conventional engine run off electricity.
2) It reduces our dependency on fossil fuel to the extent that electricity can be generated from other sources.
The *real* question is whether electrolysis/combustion is more or less efficient than charging batteries. I suspect it is much less. The electrolysis part is efficient, but the efficiency of a heat engine is easy to beat with an electric motor and battery.
(plus, where do you store the gas? I seriously doubt he is pouring water into his test car... if it runs off HHO to any great exent he's got tanks of gas, hopefully H2 and O2 in separate tanks...)
I wonder if there are different kinds of singularity, like there are different kinds of infinity...

Man, the stuff I remember from college....

1: The Continuum Hypothesis would state that c = aleph1 = 2aleph0.
2: This is how we got into the Continuum Hypothesis and transfinite set theory (which Hilbert called the "paradise of the infinite").

You own a hotel
it has infinite rooms
on Day 1, an infinite number of guests check in
your hotel is full
on Day 2, a second batch of an infinite number of guests check in
..you ask all the guests from day 1 to move up to their next even-numbered room
..the new guests check into the odd-numbered room
everyone gets a room
your hotel with infinite rooms and infinite guests is still full.
repeat as neccessary.
granted, that's a purely integer example, but it's a nice way to answer kids who (like we all did) ask questions like 'whats infinity plus one?'
