Do you have any idea of an invention that is not made yet

How about inventing a machine that exudes happiness! You have to stand on it, just as in a weighing machine and inhale some air of happiness. You can buy specific quantity for a specific amount, like 500 bucks of happiness, 1000, 2000..it could be of different denominations. Once we use up all we can go for another session of inhaling. The machine would calculate the emotional quotient and calculate the amount we would need for that point in time. This would surely make life more easier, bala. *giggles*

I don't know if anyone will give you a direct answer for this one. If someone has thought of an invention, I bet they're keeping it to themselves so that they can try to patent it and make some money.

I would like to invent a device that could tell me..what the fellow sitting in front of me...is thinking....so I could act accordingly....LOl! Good Post!

Yes, I have one that I am in the process of getting together with a patent agent. Hopefully it will be promising... :-)
