I think this voice converter is a great idea. Not simply as an electronic toy, but more sophisticated versions would do a variety of other things. Here are a couple of suggestions. Record a few episodes of some of the most famous radio comedy shows and serials from the past eg The Goon Show or whate...

I agree with Rishi - I don’t think sound waves at the kinds of noisy sites you are referring to would carry enough energy to generate economically useful amounts of electricity for everyday situations. But there are probably situations where small amounts of electricity generated from sound would be...

And is there a removable paint - similar to nail polish perhaps, made specifically for glasses, that can be painted onto frames to change their colour to match our clothes and our moods (ranging from dark and doomy to sexy-spectral dazzle!)? (Plastic will dissolve in some solvents so please be caref...

Good idea Movjo! I'm sure children who wear glasses would love to be able to easily change decorations to suit their mood, and many adults too! I wonder if magnetic shapes or characters might be easily knocked off though - perhaps either Rishi's adhesive or else a mini-clamp, screw-on or click-on sy...

Dear Mobius 1 and Michael D, I have enjoyed reading your posts and wish you success with your ventures. Here are some thoughts from a person living in suburbia who will be watching developments from good old terra firma! If you want to fill city skies with personal planes or sky cars, please don’t f...

The idea that my little computer could be wirelessly connected to a supercomputer has a lot of appeal!. I will ponder what significance your idea might have for Computer Earth. With perhaps thousands of people communicating with any one supercomputer at the same time, a big technical challenge would...

Steve says "a huge system of machines that may equally and wirelessly communicate with each other, as well as be freely used to relay communication packages of others without boundaries", and "unlimited connectivity", and Rishi speaks of "A global, boundary free connectivity...

Steve wrote "there are quite a number of countries where these cartons are collected and recycled - the metal plates would put an end to that." Good point, and I think this is easily solved. Firstly, I would be surprised if the carton recycling process doesn't include a range of steps to r...

I wonder if the electrical properties of milk change as it begins to go sour (eg its resistance to the flow of an electric current). It would probably be quite easy to incorporate two small electrode - tiny plates made out of some reasonably inert metal such as stainless steel - into the carton when...

Steve says "If I'm not mistaken, for something to smell there need to be small particles in the air. So as sour milk smells, maybe it would be possible to come up with something sensitive enough to change color even if it's not covered with milk (but just "breathing" the same air)?&qu...

I did a search for "blister pack opener" on Google. I didn't have time to pursue the various leads but there appear to be general purpose blister pack openers on the market and also devices to aid in opening pills in blister packs. I went to this link: http://www.drugtopics.com/be_core/con...

We could call the small relay transmitters-receivers on our rooftops “hoppers”. And there would need to be “island-leapers” - large transmitters-receivers that would communicate wirelessly or by cable across gaps too big for the small rooftop hoppers, eg between continents, and between cities and to...

Thanks Maskone - now I understand your EMP gun, and it sounds like my kind of device. I particularly like the “destroys” bit. And the fact that this device would enable us to put steroes out of commission without having to break and enter! You would need to be able to aim this EMP gun with a fair de...

Steve says in a Comment on the idea “Wireless Digital Camera” by Maskone (posted Thu Mar 25 2004): “There are so many millions of mobiles around, maybe it would be possible to build some kind of walkie-talkie technology into them, so the data could hop from one mobile to the next (and not via the ph...

Dear readers, can I draw your attention to the great idea by Maxokist called Robotic Visual Object Recognition. Maxokist proposes (posted Fri Apr 02, 2004 10:21 am): “I would like to see a small robot with wheels that had a camera. The camera would come accompanied by object recognition software. It...
