I know a guy who has used a device almost exactly like this one for about 15 years now, so nothing new, but still impressive.

Absolutely wonderful. I can actually see many people owning somehting like this.

Our current setup is to charge one DC adaptable device. Including a multiuse, reusable, DC chargeable battery. However, as dslunsford1 suggests, we have discussed a slightly modified version that would allow for charging a device AND the storage of extra power in a battery. Then you could either continue charging the device when you're stopped or to take the battery off the bike for use elsewhere. The core of the idea is really harvesting pedal power for use elsewhere.

My ride to work is only 15 minutes, so charging directly would only provide me a half-hour or so of talk time. However, if I could remove the battery pack and allow it to continue charging, I could probably get a full charge off a single ride to work.

Cool! So if I've got this right, your DC motor (running in reverse to generate voltage) is used for charging gadgets? How about adding a small battery pack to collect excess energy (since the cyclist will certainly produce far more than the device can handle). That way, your devices can keep charging after you stop biking.

i thought a specialiced Generator instead of a dc motor could give more power with less braking effect.

cool idea with the chain like this.. and try light Lithiumi Ion batteries
