Deep Quote by Hermann von Helmholtz
“A raised weight can produce work, but in doing so it must necessarily sink from its height, and, when it has fallen as deep as it can fall, its gravity remains as before, but it can no longer do work.”
About This Quote
Source Treat: Lectures on the Theory of Heat, 1867
Energy can be extracted from a raised weight only until it reaches its lowest point; after that its potential is gone despite unchanged gravity.
In simple terms: Work stops when height is lost.
Key Takeaway
Use energy before it’s depleted.

A Different Perspective
Even with same gravity, no more work can be done without height.
![“I've used the Phoenix Centrifuge to replicate what the body's going to go through on the flight up. I've also done some gravity tests with ZERO-G [a charter-flight service in Arlington, Va., that uses modified Boeing 727s to simulate weightlessness], which went great.” quote by Richard Branson](https://sms4smile.com/quotes/img-quotes/aa1/richard-branson-256_adventure_i-ve-used-the-phoenix-centrifuge-to-repl_903.jpg)
