I must admit, I always tape it so I don't miss it. It is always interesting to see some of the ideas that some people come up with. Some of the inventions are brilliant while others are a bit...well...dumb? Always entertaining, I wish I could think of something too.
I invented the electric motor when I was 11 unfortunatley I did not know it was already done, I invented teh flying ring only to find it had been done, I nvented the "Trumpet mirror"as I call it but it was already in the xray scope so that was out...but the one I rally laugh at was a thrust paddle for a boat the opened and closed as you pushed and pulled..I saw it in a Chinese wood print thousands of years old..
Add to that my patten attorney talked me out of pattening my wrist worn calculator 30 years ago I think inventing is simply not for me... its fun but I have never made a quid out of it..not saying you cant but you really have to be strong to not give it in.
