Maybe once a year, the internet throws up something that is so cool, so incredibly amazing, that you sit back in silent awe. As a young child working out that I would turn 13 in The Year 2000, I wondered what kind of futuristic madness might be available by the end of the first decade. I could never have imagined this.
Behold:
Unlike a standard speaker that uses magnets/paper/plastic etc, this plasma speaker uses the non-gas, non-liquid, non-solid, "fourth state of matter" plasma to create compression waves. The pitch is altered by the constantly shifting intensity of the plasma arc at a frequency response range at 200Hz to 12kHz.
When asked if he ever considered selling his device the creator replied, "A lot of work to do before I could consider selling - the safety aspect for starters..." Fair enough, considering that the universe will be destroyed if two of the plasma speaker beams cross. Yes. Ghostbusters was scientific fact.
