best battery powered bicycle lights image
Sexy
I'm looking for either one of the following 2 things:
1. A bicycle light that is powered by the wheel but has a battery that kicks in if you're going too slow for the light to be bright.
-OR-
2. A bicycle generator that can store the generated electricity in a battery that can then be used to power a light.
Thanks.

Generators disappeared from bikes once batteries were commonplace. Now, with LED lights, a couple batteries will last 1500 hours. In any case, here you have a few.

How can i power a kettle with a bicycle?
Q. So I'm in college in Ireland and we're running a green week very soon and for fun I want to see if i could run a few electrical devices with the power of cycling. Anyone any ideas on how I could get my hands on the equipment to do that?
Answer
You really have two choices the '12 volt route' or the '240 volt route'.
There are small kettles that run on 12v that plug into a car lighter socket - so you could charge the car battery from an old bike dynamo and run the 12v kettle from that (by propping up the back of the bike so its off the ground, or (even using a smaller sealed gel battery that could be put into e.g a saddlebag).
To use a mains 240v kettle is more tricky- but possible, here you will need a substantial car battery ( charged from the bike - maybe get hold of an old car alternator and run a pully system off the back wheel? ) and an inverter that will cope with the wattage of the kettle, most modern kettles are very high wattage but you can get 1,000 watt versions. The problem is that a 1000 watt inverter can be expensive, probably around £70 but check ebay?
These are only ideas, don't do it or mess with mains voltages if you don't know exactly what your are doing and can do it safely, better still take the advice of qualified electrician!
All the kit needed can be found on ebay
