Engineering: Mechanical Flywheel Batteries

For thirty plus years I've been wishing the USA would invest in mechanical battery technology.  Unlike chemical batteries, flywheel batteries don't wear out and are extremely efficient.  As far as I can tell the only drawback is they take more engineering to build.  Really ?  

So uh duh ?  If that is true then all we need to do is invest in micromachine manufacturing technology and we can have zero emission cars that run for a hundred years.  Seems like an obvious choice to me.  Are you listening China ?
