Hamburg-based Alexander Weber, a "Program Manager and a Software Architect by day and tinker with electronics by night," lives up to his self-description by showcasing the Almost Useless Machine, a solar powered contraption to cut 20mm wooden rods.

This little machine uses a so called solar engine to drive the motor. This solar engine is able to collect tiny amounts of energy over time and stores it in large capacitors. When the voltage reaches a certain level, it opens up and uses all the stored energy at once to drive a motor.
