Have any of you tried to get an idea published and not succeeded?

I have. I got doofed by Dave Gorman's "Genius" page on the Radio 4 web site (see Genius ).

My ideas included (ideas I might add, which are potentially lucrative, which involved lifetimes of dedicated research, which were inspired by one off lightning bolts from God him/herself) (Did I get a reply? did I? hunh? I think you can answer that for yourself(ves!)?)

So here we go here's my brain spillage:

1) A machine that changes things.
It is endowed with the ability to sense things that need to change and, with various motors and pipes, will implement often subtle but necessary changes to it's surroundings.
For instance if placed in a field full of land mines, it would use it's feng shui database to clear it.

2) Time powered machine
How about a device that's actually powered the time component of the space-time continuum itself. As time progresses, a series of highly efficient temporal energy extractors provide power for processors or actuators to display the time on a digital counter or numbered dial according to how many minutes, days, hours, or seconds have passed.

3) Tree bag extractor
Do you know, Dave, just between you and me: what should be done about plastic bags that end up in trees as straggly tatters? I had a brainwave about it the other day but I didn't write it down. Can I get back to you when I've thought it through and remembered it properly?
Cheers, Hugh

4) 'Bookture'
Excuse my ignorance but they put pictures in books, but why don't they put books in pictures?
The "Bookture" is, you've guessed it - a book and a picture combined. A specially converted frame allows the pages to be turned via an ultra-compact flanged ratchet mechanism.
No need to hurry through a book turning page after page trying to get to the end as quickly as possible. Just stick it on a wall and read a word or a sentence or even a paragraph completely at your leisure whilst perusing around your house and gandering at your picture collection.
No need to squint at a piece of abstract art trying to interpret it's meaning through it's abtruse and raciondite symbolic language - the page says it all–in plain english!
Throw away all your pictures, burn all your books and buy a "bookture"! One for the bathroom, two for the stairway, three for each bedroom, that's twelve, four for the living room-you won't need the TV- that's sixteen, and you could have a cookery bookture in the kitchen, that's seventeen! And let's say £45 each, that's going to cost you, ooooh, £765, I'll knock it down to £700, for you, Dave, I'll bring them round tomorrow, yeah?

Have you had any ideas that you've tried to send into Dave Gorman's "Genius") page? and failed? Why not stick it here? I don't mind taking the credit, if it's significant enough... Go on, send it in. Give it a good airing on my friendly Blog page!
