Another method to implement continuously variable behavior is what locomotives and many garden tractors use - instead of connecting the engine to the wheels, they connect it to a generator (for the locomotive) or a hydraulic pump. The output of the generator is connected to electric motors to drive the #train, or the hydraulic pump to a hydraulic motor to drive the tractor.

This is durable and simple... but it's hideously inefficient, there's lots of loss at every stage.

Most common CVT designs use a variable diameter pulley system.

If you're familiar with #bicycle derailleur gearing, you'll know that when you have the chain on a small sprocket up front, and a big sprocket in the rear, your pedals will spin fast relative to the rear wheel, and when you have it on a big sprocket up front and a small one in the rear, your pedals will spin slow relative to the rear wheel. VDP CVTs simply use adjustable width pulleys to get this effect, usually with a rubber belt.

So I feel like talking about power-split transmissions, as I think they're a really clever way to get continuously variable behavior.

Wew, my projected Verbal score blows surprisingly hard

I'll take the Math diagnostic later

A mighty war rages across the multiverse. It is the war between

MATHLIKE PARENTHESES

and

LISPLIKE PARENTHESES

Who will win? Who SHOULD win?

1. Mathlike parens! As seen in, eg, combinatory logic.

(a b c) means (a , (b , c))

2. But Lisp says NOOOPE! to that. In Lisp,

(a b c) means (a , (b, (c, NIL)))

and if you want the first type you have to say

(a b . c)

with an extra dot that you have to parse and omg wtf

BUT it's also pretty great for lists!

This war sucks but will never end.
