Yes, a good point.  Your phone has to be working before you can charge it. Wouldn't work for me as I usually don't remember to charge it until it has died on me!

The text message is redundant if the fellow on the bike is there to operate it and monitor who is plugged in but it does offer the possibility of running as an unattended faciity.

P.S. it is not MY idea...I was just trying to figure out how it works from looking it up on their (BuffaloGrid's that is) web site.

The opportunity already exists for an entrepeneur to but a generator (be it hand, solar, pedal) and charge people to use it. The only innovation I see here is to give the cell phone companies a cut by requiring SMS payment. One way of attracting investment for your idea I suppose, but surely better to keep the cash in the local economy? Also, cell phone reception is needed before charging can begin.

After clicking on the link to the BuffaloGrid project it seems that their project is to make available charging boxes and solar panels.

- The man on the bike as an entrepreneur is selling cellphone charges

- the charger is in the white box on the handlebars and has a battery and 8 separate USB ports for plugging in cellphone charge cables

- the gizmo over the back wheel seems to be simply advertising for the service

- the orange frame is indeed a bike stand

- it appears that the charger box is itself charged by solar panel that the entrpreneur receives as part of the package

So when the fellow arrives in a village everyone gathers round to plug in and charge their phones after first sending a text message to pay and unlock a charging port.

A clever and useful small business enterprise.

I will stay tuned Elizabeth; it's an interesting subject!

Good point.  In the photo, the orange structure attached to the rear of the bike appears to be a stand that can be rotated under the rear tire to lift it off the ground.  In fact, such a stand is typically used for transforming a bike into a stationary exercise bike (not likely!) or a generator.

That's a good idea, Cabe. Probably a bit less cumbersome than dragging around the generator on a bicycle. Wonder if the project founders thought of that? I can ask.

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.
