Inventions

[the joint]

When I have ideas for practical inventions, I often wonder what others think of them, or if they've already been thought of.  This is a thread where you can post any ideas for new inventions or products, or to provide feedback for others.

I'll start with a few of mine:

1) A refillable, concentrated caffeine spritzer built into a mechanical pen/pencil for long work or study nights.

2) Natural-looking, synthetic firewood, refillable with flammable liquid that is released externally at a controlled rate to simulate burning of real wood.  No more chopping/buying firewood, disposing of ash, or cleaning chimneys.

3) Small hole built into driver's side of vehicle that sucks cigarette smoke and ash and dispenses it cleanly outside of the vehicle.  Smoke in rain or snow with the windows rolled up without hot-boxing the interior.

I like the faux-log idea!

I've always wanted to build a 3d where waldo world, except be evil and not include waldo.
