h a l f b a k e r yI like this idea, only I think it should be run by the government.

Having trawled the net I could not find this idea anywhere. So here is my first submission to this site.
As the title states, These cycle tyres would illuminate at night creating 2 beautifull halo's for all to see. Obviously increasing visibilty.
The tyre and inner tube would be manufactured
from a clear rubber / polymer , at least the wall of the tyre, but possibly the tread too.
A number of LED's are moulded into the inner tube to direct the emmitted light along its internal wall, with micro thin wire also moulded into the tyre connecting them all together.
The light would permiate throught the clear wall internally reflecting to provide a relatively large coverage of light, also the light would be clearly visible directly through the transparent tubing and tyre, the whole effect being amplified the faster the wheel rotates.
POWER
i/ Batteries mounted in a small water proof casing mounted on the rim or on the spokes
ii/ Power could possibly be achieved by an electro motive effect if more wires were mounted in the tube and a magnet placed near the break blocks
iii/ Or...... A kind of piezoelectric effect where the compression of the wheel generates pulses of energy that could be stored / used in small cells mounted inside the ninner tube
(?) Glow in the dark bicycles.

Notice the luminous wheels sentence ? As in link.Cool ! |

Nice! Well done for doing some research - many don't. I think you'll have trouble with the transparent rubber material, but there's nothing to stop you having a thin, clear plastic wheel rim to put the tyre on which is lit (ok, so it won't look *quite* as cool). As for power, I always loved the old dynamo's. |

Welcome to the Halfbakery. |

Hey [skin] - did you read the last post on the page you've linked? I may have to write to this guy, he and I have big room to cooperate. |
|

ha, ha, ha, ha, that's ...sorry <aside>falls off chair <aside> Yep Wags, got it. |
|

good call. I can't tell you how many
cyclists I've accidently run down in the
dead of night. |

And here I was thinking you were going to do things the easy way, and make the tires out of glow in the dark (photoluminescent) rubber, and then I could crack some jokes about skid marks... |
|

Well, maybe you could. Getting the whole thing to glow without riding around under a lightbulb would be a little tricky. Maybe you could just do the part that is inside the treads, so you'll also know when the tires are too worn out, and if it's photoluminescent all the way through with lights on the inside... |
