6 FAQs about [The high voltage cabinet outlet spring has no energy storage]

What is spring based energy storage?

Spring-based energy storage is common in toys: jack-in-the-box, snake-in-a-can. I've heard of the opposite system - a concrete block on springs, say, a sidewalk paver in a busy city. As people walk on this block, it compresses the springs underneath it and - something-something, kinetic energy is stored for later use.
