Some ideas if been kicking around…..free and reliable energy….adapters for power tools that are either missing its battery or that battery is no longer made.This adapter would be able to latch on to the tool and securely and provide power in the form of leads with super magnets on the ends to attach to the terminals of the tool locking them in place and providing power. Magnetic joints that do not touch-wear out the point of contact because there is no contact! Strategic points that enabling them to move from one position to another, by turning on and off these magnets u can manipulate the arm into any position; with no friction they would last longer and have a larger flexibility and would be easier to service those components. Moving parts that would be unaffected by wear would last longer and require less to maintain and or change its function all-together!
