Most answers are out there you just have to look. Are you looking to answer my questions posed on this form? You must engage to succeed in your careers.

What could be done with an energy storage medium having the energy density of batteries
and the temperature insensitivity
and burst power capability of a spring?
For high-power applications, springs could be released in groups; for low-power applications,
energy could be released gradually through a ratcheting mechanism similar to the
spring-driven escapement of a mechanical clock.
One potential application might be portable home tools that currently run on gasoline engines.
For example, after winding up your
spring-powered leaf blower, you could clear leaves more quietly and cleanly than with a gas-powered blower.
Spring-based energy
storage may also have advantages for leak-free long-term backup power supplies.
