Make you own Island Printer Friendly Version
As the population booms, overcrowding is becoming an ever increasing problem. So, why can't we make our own land? Now I've seen this done, I know that they did this in Japan for a new airport... I think. Can't they do it on a much larger scale, to make a land-mass? It would be a big project and take a long time, but I don't see why It can't be done, I think we have to consider this option before we think about moving to mars!

Automatic Toothbrush Printer Friendly Version
I did a science fair project on this one... A tooth brush that had tooth paste in the handle which would dispense through a tube into the bristles. Of course to market such a thing it would either need to be disposable or refillable. I had a proto-type at the fair and everyone liked it. What do you guys think?
Reward: Just the satisfaction that I had a good idea.

Rotating Cone Helmet Visor w/Stationary Wiper Blade Printer Friendly Version
Suzuki_girl saw a post of mine and emailed me about her university project involving a helmet with a reciprocating windshield wiper blade. Below is a drawing of an alternative that I came up with. I ride motorcycles and would like to see something like this on the market.
Reward: Send one to Suzuki_girl
