Smart-phone weather station Printer Friendly Version
Add-on feature for any smart-phone to read and record wether data. From temperature, humidity, barometer, and wind speed ... to even maybe a point-and-read thermometer. Simply plug into your phone and gather more accurate data then any weather station can offer.
Include a simple user-friendly app that pools all of the data into useable information for anyone to access. This could someday make weather stations obsolete with millions of readings being recorded.

Energy production Printer Friendly Version
If we are able to make small hydro power generators that we can easily generate power from very small streams in our neighborhood and even from a water tank. Let the water, being pumped into the tank, flow on a fan (fixed inside the tank) which can produce electricity. Thus we can generate almost the same energy spent for pumping water into the tank. That means energy used is generated the next moment.
Reward: I would be happy if I get such a product for my own use. Please let me know if it is already in use.

One CPU, one screen, two users Printer Friendly Version
Why can't we create a computer with a front and back screen with a single cpu. The CPU would have two hard disks which works for both screens individually. So that two people sitting opposite of each other can work independently.
