This is a clever idea: A solar-powered charging station for cellphones, pads, and other electronic devices designed as a standalone architectural amenity.
The Street Charge standalone charging station by Goal Zero
Made by Goal Zero, experts in solar powered charging systems, these elegant stations called Street Charge are being shown at events in twelve US cities through Goal Zero's current "Solarize America" campaign. So far Austin, Miami, and Cambridge are scheduled with the other nine still to be selected (if your city or event wants to get in on this, contact Chris Abbruzzese at email@example.com).
Following Hurricane Sandy last summer when power and communications went out for a large section of New York City AT&T installed 25 Street Charges; you can find their locations on the Street Charge map.
The Street Charge has solar panels at the top which charge lithium batteries in the column to provide power both day and night. As an amenity for locations such as parks, conference centers, golf courses, and hotels the Street Charge becomes not only a power oasis but also an information center and, with the addition of a WiFi access point, a communications relay point (which would need its own power supply ... and Goal Zero sells solar panels such as their Boulder 30 and power packs such as their Sherpa 50 that could do the job nicely).
