Child Drowning Necklace Alarm Printer Friendly Version
A necklace that needs to be out of water periodically or it sets off an alarm that is installed by the pool. Now that would save some lives. Something colorful that the kids would wear.
You could calibrate it by having the child staying under water as long as they can, then setting that as a maximum time before alarm goes off. Thanks. Please, somebody get rich with this idea for the sake of the kids.
Reward: hearing that the government has made these mandatory for children in pools because they save lives.

Solar Tiles Printer Friendly Version
Base - Solar panel - Between cover glass and transparent adhesive places luminiferous additions which makes solar emission stronger in air-bubbly cover-up.
Appearance - Form will be as a tile; color can be changed - Can be placed in different types of tiles, but the most effective is as showed on picture, because during whole day panel can collect right solar emission. To change color is able to put active (reactive) colorants out of they can outstay high temperatures, their lifetime is really long and they aren’t very expensive.
Price - Not more than 35$ - For 1 tile which produces ~ 30W of electrical energy. The person who buys the product can easily calculate how many tiles he needs so not to waste more money on useless. The buyer can save some also because he shouldn’t buy usual tile in place of my product (For my home I’ll need ~100 tiles and it will pay for it-self ~ after 1,5 year)

Jet Engine Energy Recycle Printer Friendly Version
The basic idea is to harness the energy created from the thrust of a commercial jet engine. You would place another turbine behind the main turbine that is propelling the jet forward, except this turbine will not be pushing it forward, instead it will be harnessing the energy created from the thrust of the main engine. As the main turbine is powered by the engine and is running, it creates a powerful stream of air that will turn the second turbine and still let the air flow through. It may lose a minuscule amount of thrust, so it will not make much of a difference in regards to power. Thus, as the second turbine turns, it will create energy that could be fed back into the plane to power anything, like possibly the electronics in the plane(A/C, lights, t.v., etc.).
