Reply to New harvester amplifies electric power generated from human walking motion by about 90 times. Since the power generation performance can be improved without increasing the device size, the technology is expected to generate power to drive small wearable devices from non-steady vibrations by Wagamaga
The latest high-quality content on /r/science: perpetual motion! You put in a little bit of energy and this special device “amplifies” the power and gives you 90x as much energy back!

Reply to Water line from house to barn lost pressure! Please help!? by Castle_33_
FYI it is possible for water pressure buildup from a broken line to damage a basement foundation wall, i.e. to crack it and cause it to start leaking - if you’re going to let it run for a long time hoping to make a big puddle somewhere out along the line, just make sure to check periodically for signs of water right up against the house.
