A piece of wood by any other name...
Hardly a brilliant invention, using magnets to float things off the ground is a common thing, particularly in regards to maglev trains. Besides in order to work on the street you'd need magnets implanted into pavements/sidewalks. Yeah, that'll happen, just to make skaters more entertainedThen all great inventors have a difuncional mind. I to am also inventor, invented the skateboard without wheels, follows: invented a flat magnet that repels magnets we're below the skateboards.
Criticising someone's idea doesn't require the person doing the criticising to have an alternative idea. Plus it is better to realise one hasn't got a good idea than to have a bad idea and go around extolling its supposed virtues. Something no idea is better than a stupid one.Would I not I sneer of an invention of yours.
