Ha. I was so bored in the class that I actually come out with something that I would like to do/have in the future.
a. Convert the wavelength of the sun radiation which is ultraviolet to infrared and use them as heat to generate power/ convert the infrared radiates from the earth to ultraviolet so it will not be so hot and reduce the green house effect. No sure whether the conversion will help or not.
b. A portable anti-virus device with usb port. Just plug in the device into your computer via usb, and it will clean up the virus. Then, we do not need to install anti-virus and our computer acan operate faster.
c. "Screenless" television. An adjustable width, space-saving and ultraportable television.
d. Simply drill 100km inside the earth and get the heat there and generate electricity.
e. "Living" volcano. Use for power generation also.
f. Electric shield. Simply create lays of electrons and protons in certain arrangement to create a shield. This shield can be use for multi purposes such as accident safety system and even nuclear bomb preventation system. Still have to figure out how to arrange the electrons and protons though.
I haven't started my programming!!! Lalala.
