I'll have to get back to you guys on this, TJ. I didn't get a chance to talk to the founder of the project for the story. He did contact me a week or so later, so I can follow up and get a more detailed description. Stay tuned.

Elizabeth, Mydesign's question is, I think, how does the electricity get from the charging station to the cell phone?  That was going to be my question at least.

The phrase "maximum power point tracking" describes what the solar cell portion of the system is doing (had to look it up).

Is there some form of non-contact inductive charging going on?  Or is a micro-USB cable so obviously necessary as to be left unsaid?

I'm with Chuck and Cabe. Even beyond bikes, nearly any form of transportation -- including walking -- can generate sufficient energy to charge a cell phone.

I also think they'd get more current using your method, Cabe.

Why not use the bike to charge the phones? Sit on it and pedal, spins a generator.

Yes tekochip I also agree with you,

I think that hand mobile charger is the best option for this matter.

I think that cell phones are probably a little easier to get in some of these countries than solar panels, although I am not sure, tekochip. I imagine they also are on "pay as you go" services, not service plans. But as I said, I don't know for sure. I just would think it might be hard for someone to purchase a solar panel. I live in southwest Portugal and even here I would find it hard to get one; I'd have to go online and have it delivered. And the mail in Portugal is quite bad and sometimes I don't get packages or have trouble receiving deliveries, so I can't imagine what it might be like in a truly impoverished place.

Hi, Mydesign, thanks for your comment. What do you mean "the mode of contact"? I think I am a bit confused by your question.

What's surprising to me is that the potential customers can afford to purchase a cell phone and service but apparently can't purchase a small solar panel to charge the phone themselves. I just checked eBay and a typical panel is about $5. The solar idea is great, I just don't understand why they need a guy to pedal it.
