Some scientists from the University of California discovered that you can create X-rays by unrolling a roll of scotch tape. It needed to have a strong current so it only worked in a vacuum (airtight space) because of the moisture in the air. Before, scientists had discovered that unpeeling tape could produce light. The tape is technically a mini X-ray machine! Now these scientists face an even higher challenge: "there's the possibility of nuclear fusion. If the energy from the breaking adhesive could be directed away from the electrons to heavy hydrogen ions implanted in modified tape, the ions would accelerate fast enough so that when they collided, they could fuse together and give off energy — the same process that lights the sun." I also think that is quite similar to solar panels. Solar panels have electrons blasted off by the sun; nuclear fusion has the hydrogen atoms blasted off by electrons. source: nyt
