What ideas of inventions do you have?

Question

i want o invent something, and seel it!have any interesting ideas?

Answer 1

you could build a perpetual motion engine, which is impossible. if you can do that you are totally awesome...

how about a car being powered purely by water? there are actually flaws about the invention of cars that use water as their source of energy...

reusable condom...? :D

a spaceship that could make a wormhole, that sounds interesting...

a warp portal or teleportation device...

if you want to invent something and SELL (not seel) it, you yourself should think about it, you must be the one to develop the idea. if you can't then even if we give so many interesting ideas, you just can't do it. besides you can't say that it is purely your invention since it's not you who made the idea.

if i were you, look on the things happening around you, look for problems that occur right now and check if you could change them or improve...

Answer 2

Here's one you can have.  The coin operated headstone.  So when you visit a cemetary you could drop a quarter in and the deceased could give you some advice, or tell about his hobbys, whatever he felt like saying.  The proceeds could be used for the maintenance of the grounds.

Answer 3

Big part of inventing is coming up with the ideas.

Also learn how to spell.

Answer 4

Well, currently I have more than 20 ideas for inventions. Three I have prototypes for. I just never follow through with the patent part of it. Most are tools.
