Yes even modern engines can surge at high load in, for example, air outside the acceptable working temperature and the compresser temporarily stalls,...
Yes but low pressure sodium puts out about three times more lumens per watt and the blue needed for phototropisms is a tiny fraction. If stuck a long...
One efficient light is sodium or high pressure sodium , very yellow in the low pressure type. You can grow lettuce in that almost monochromatic light...
What interests me is the range of forces on variable geometry. If you set a target of lifting a few tons per board at say 5 knots and then sailing at...
I am just an engineer, but I think the better question is about inertia. Is inertia a thing? This is at the heart of equivalence and is separated out...
Ha! I get that too and react the same. In UK many say “mate” which I think came in from “down under” with soaps. The French/Belgian equivalent to wee...
It is possible to use human power to get onto foils and there is an MIT record. I was involved in human powered races and you need to generate about...
Because it is a racing formula, the rules are tight, but still the design variations are quite large thisyear. The hydrofoil wings for exammple vary...
There has always been a non-intuitive element to being able to sail faster than the windspeed and now we can see how close we are to sailing directly...
