How can i sell my invention?

you can try but ideas are a dime a dozen. The real value is in implementing the idea and actually selling it.

First - see if it works (create a home-made prototype, if possible). If yes, go to the patent office immediately! Then, you have 2 opportunities: a) go to a big company and sell them the rights to manufacture it in exchange for percentage of the profit. Positive - easy way, cus having a large corporation as an ally is good; Negative - if it is very smart, they may steal ti from you (consult a attorney to protect yourself). b) start your own private business and produce it and sell it. Positive - all your profit is for you; Negative - too risky; if you fail, you will bankrupt and lose even what you have (if you took a loan, which is often needed to start business). Choice is yours! Think well and ask people for advice. Be confident, enterprising and vigilant! That's how many dreamers turned out millionaires... :)
