Very interesting! Good to know that not only Apple, Google, Microsoft making some innovation.
Write more about innovation in different area of Science
thank you
Whenever metal touches metal of course you have friction.
The more cylinders and size equals more power and yes more friction and less efficiency.
The few cylinders and fewer metal parts touching provide higher efficiency.
Efficiency is one goal, but being effective is a necessary goal as well. An engine must be enduring and last a long time. When you have one cylinder or 2 or few the engine is becomes much more difficult to keep balance in its vibrations. Vibrations and engine produce frequencies can wear out and tear a engine apart.
So it is a trade off of more cylinders or less. Making an engine is a very real engineering science.
I look forward to read more about this articles engine in the future. It reads promising!
