Why do golf balls have dimples?
Back in the day golf balls used to be perfectly round. Golfers noticed old beat up balls flew farther. Why? Turns out the imperfections create a turbulence that in some situations let the object fly farther due to the less drag.
What does this have to do with turbos?
Lots.
Nikola Tesla improved the bladeless turbine back in 1913 and his improved invention the Tesla Turbine was said to be 95% efficient. Today's bladed turbos are about 70% efficient.
How does a bladeless turbo spin?
It is counterintuitive but think of wind like you think of water. As water sticks to whatever it touches so does wind. As air blows over a surface the first molecules stick to it -this force is enough to get the blades moving and is called the boundary layer. His first motors spun at 35,000 rpm. The materials back then could not handle it.
Could this old technology lighten today's dark age?
Are we living in a dark age?
Yes. Look back to the engineers and scientists 100 years ago.
Niels Bohr- Explained atoms.
Albert Einstein- Discovered energy and mass were the same thing.
Nikola Tesla- Invented A/C motor and thought about Free Energy.
Rudolf Diesel- Invented diesel engine.
What do we have today to compare. Google and a crappy two wheeled scooter.
