- thermal battery for A/C and heating - wind-up battery - flocking navigation system for airplanes (to save on fuel) - hybrid hot water heater - pre-heats water to ambient temperature in an uninsulated water tank and then heats the rest of the way on demand with a tank-less water heater (someone told me that already have such a system at their cottage) - forced air BBQ heat exchanger - 3D house plotter: someone else had the {link:same idea|http://www.discover.com/issues/apr-05/features/whole-house-machine/}.\\ - smelter / baking produce heat exchanger - electro-magnetic transmission using {link:Ferrofluids|http://www.carolina.com/physics/aboutferro.asp}. The magnetic forces wouldn't need to be strong enough to hold the gears, mearly strong enough to harden a thin film of Ferrofluids (liquid magnets which become solid when exposed to a magnetic field) in order to make a physical connection. If the gears where cone shaped and running along side each other in opposite directions then you could probably make a continuous differential gearing system by controller where you create or aim the magnetic field. - cell-phone cradel for providing land-line like service to POTS phones {link:already done|http://www.celldock.com/} - SAM - Sequential Access Memory - ideal for MP3 players - eccentric gear for recumbent bicycles - laptop palm-pilot, kind of like {link:this|http://www.everymac.com/systems/apple/messagepad/stats/emate_300.html} or {link:this|http://www3.alphasmart.com/professional/index.html} - sculptable keyboard with movable RFID keys (and other components) - gene-spliced "cornucopia tree" which bears multiple species of fruit (and many "vegetables" like tomatoes and peppers which are also actually fruit) - spherical robot with no moving parts - driven by controlled activation of electromagnets lining the inside of the sphere - only works on metal surfaces - fuzzy micropayment system makes small payments viable by using probabilistic money (others came up with this idea first) - a computer mouse which remaps my keyboard layout when it detects that I have my hand on it. When using my mouse with my dominant hand my keyboard would be remapped into "mouse mode" where the keys under and around my non-dominant hand would change to things like: arrow keys, delete, backspace, tab, cut, copy, paste, home, end, page-up, page-down, etc. - RF shielding on the inside of my clothing pockets so that when I cary around things like cellphones I'm not radiating myself. {link:related|http://www.sciencedaily.com/releases/2005/03/050328182920.htm} 2006-01-04 15:40:07.777 2005-04-09 12:01:39.632
