CL, i was able to see your google map of the free charging hubs. i would still like for people to label them 'justin junctions' so that the google search doesn't turn up the other stuff.
i also believe that google maps is too much overhead to maintain eventually. it seems as though the best place to organize it is in a list file based on gps coordinates or local zip codes.
the biggest issue i can see for an open network of charging spots is the need to maintain security, by the owner of the electric service and property. they need to know who is on their property, and i would even say they deserve to be reimbursed for the juice. even charging a huge 48V60Ah mega pack from 70% discharged back to 0% discharge, which would take almost 15 hours would consume about 2kWh of power, around 20 cents. a small 500Wh charge would be about 5 cents cost to the owner. you should be capable of explaining this to the property owner in simple terms.
it would help for everyone who follows to show respect for personal property rights, and if confronted i would suggest that the person using the plug immediately offer to pay for the juice and explain how much they consume and how much it costs. just the explanation and offer of a nickle or dime may mollify the situation, and reduce the resentment inherent when there is such a nominal trespass of the owners property. they will not see it as trivial, but it will present that bike owner with the opportunity to evangelize the value of electric assist bikes to society and the inherent need of charging locations to support them.
i would appreciate it though if you go back into your user created file and relabel the 'plugs' with a new designation, "Justin junctions" and enable "JJ" as an identical search object too.
it would help if the query would read something like 97202 JJ? to search for a charging plug here in my neighborhood, using the local zip code. the structure needs to be able to handle what eventually will become a huge file which can be reached through cell phones and blackberry devices too.
there is a guy who did a similar map for EV's in copenhagen. he actually has the info barb in the bubble on the map, i lost the link, but i saw it in my evchargernews.com mailbot. they are much further along this track than anyone here, you should get on their mailbot, even though it is just southern california, a lot of people outside of SoCal who are interested in universal charging hubs have posted up stuff there too.
