Eyes for the blind Printer Friendly Version
Here's a big one:
Do you have the technical skill or know someone who has?
I live in Paris. In the halls of the metro station underground at Duroc station, I was walking behind a hand-in-hand couple who were blind. They talked endlessly and tapped tapped tapped along. The corridor turned off to the left. The couple followed along in the middle, like not even thinking about it - with the curve. How did they know that? Ahh! because they heard it turn. They had not tapped the wall, they just eased along in the curve.
Then I thought of a flying bat. He has no eyes, but he avoids problems and finds small flying insects at night. He emits a radar sound that the return of which he uses to judge, by the Doppler effect, to tell distance and form.
I imagined....Imagine a blind person with a pair of spectacles with antenna at each end that emits a series of waves, the return of which he uses to calculate automatically, as a bat, distances and forms. The doppler effect, if you don't know, and excuse me for assuming you don't: is that the shorter the return of a sound the higher the pitch: listen to a train coming and how the sound rises at the approach until it passes. If we can use doppler, and we do, to explode artillery shells and kill people with shrapnel, surely we can figure out how to do this. I'm isolated and seventy-nine or I would do it myself!
Reward: I've had a lot and now I have nothing: I'm the Poorest guy in Paris, which might be better than being the poorest guy in Peoria, so if you can use this and I hope you can, Appropriate dried or boxed food would be gladly received.

Sticker Printer Friendly Version
A sticker, with a clock print. 1-12, with a plastic needle that can be turned. This way, one could stick it on medicine packets and turn it each time one takes their medicine and remind of the excact time it's been taken. It helps, to get reminded when to take it next.

Paracetamol in chewing gum Printer Friendly Version
I would like a chewing gum that has paracetamol in it or similar. This would be so much easier to just chew and the body would absorb the paracetamol instead of buying headache tablets and having to swallow them with liquid. Making the product available in similar packaging as chewing gum but to market it where paracetamol is sold in the grocers.
Reward: the company that markets this would give me everlasting supplies
