Video Party Printer Friendly Version
This may sound nuts. But i have an idea for an invention for parties. Not that we dance or anything at the parties I go to, but what if videos or DVD's were sold of music videos. While they are playing, bright lights flash. Strobes, colors, anything. Kinda a rave thing. But I figure why rent lights or have to make mix CD's most TV's have good sound or a surround sound system. I'm not saying this is going to be popular for epileptics, but everyone else should survive. Just a thought. If you don't think it will work, turn on Cop's turn off the lights in your house, and look at the walls when they pull someone over. It gets pretty bright. Tell me what you think.

Maintenance-Free Shade-Trees Printer Friendly Version
They've already discovered maintenance-free grass (requiring no mowing). Now, how about botanists developing a tree whose growth can be controlled to a certain height, and which either has evergreen leaves, or else leaves that aren't a pain to rake. I think the honey-locust may have more manageable leaves, but can it grow in cool climates, too? In hot weather it's energy-efficient to have shade trees cooling the house, but they're such a PAIN to maintain. If only there were a solution!
Reward: Best of all the worlds, labor-free shade.

Free Clean Energy from Garbage/Trash/Biomatter Printer Friendly Version
Garbage/trash dumps and also biomatter from farms etc. create heat in large dumped volumes. If a water contaner were to be placed into the center of the mound of trash or bio matter or coils of piping were placed in the center of the rotting mass, hot water could be produced for washing, or house heating for poor populations living nearby.
Reward: Free for the greater good on the condition that it's acknowledged Greg Jones is the originator of the idea.
