Fun fact: the experimental contraption produced hydrogen which was burned off in a dedicated chamber. About 5x3x2 meters or so. Or in retard units I guess 15'x10'x6' or some such.

A couple of years back I participated in building an experimental gasifier. Sort of a huge wood gas generator, only modern. I designed the structural parts.

Oh, I have dreamt for many years of making an “A tractor”...

Last time I traded in a car the dealer asked what I wanted for it.

My method is “It’s 10k. Oh, you want to haggle? Then it is 12k.”

I have heard of instances where someone took a V8 and converted one bank to a pump, effectively driven by the I4 on the other side.

Agreed. I used to hate Volvos mostly out of principle (as a SAAB guy) but I have a hard time finding fault in them these days.

A few thousand RPM per second is the derivata of RPM and thus appropriate if you speak of how fast revs rise and fall.

Small town Sweden, 1980 or so. Everyone drove a Volvo 140 or SAAB 99 or some such.

I concede that you have a point. Points, even.

HD suffers from two problems: the douchebag stigma, and that most of their bikes look like an unbalanced assortment of components that do not really belong together.

Oh wow - that is absolutely gorgeous, and I don’t even like cruisers. They did HD better than HD here.

Good looking stuff, but unfortunately Harley carries a stigma of being for douchebags and old men, that they will die with.

Not cars, but motorbikes: my parents live on a Greek island named Kalymnos, and the (ca 10000) citizens there have a delightful contempt for earthly things such as vehicles.

I mean, have you ever been driving around and gone “Blimey, I was revving 2200 rpm before, but now it is 2300!” - just why is that information continuously presented, what am I going to do with it?

Rad/s is the proper ISO unit. Radians are convenient, because they remove the need to use conversions.

Fun fact: Sugga means sow in swedish. As in mother of piglets.

Water is unfortunately not ideal for this, as it absorbs enormous amounts of energy when going from liquid to gas.

Oh, Peltier elements? Hm. Interesting.

That is a good question, and I do not really have an answer, but I suspect it is because of the same reason as for gas turbines: that energy is fairly high entropy = low concentration, diluted to low temperature in a large quantity of medium. Meaning that it takes a lot of effort, equipment, space, cost to gather.
