The 2nd Cleanweb Hackathon NYC took place Friday 9/28 to Sunday 9/30/2012 at AlleyNYC; bringing together software developers, designers and entrepreneurs to brainstorm solutions that address issues with energy/efficiency, waste, water, transportation and global resource constraints.

Teams were be equipped with datasets, APIs, pizza, and coffee, and teams will present their app prototypes to a select panel of judges on Sunday afternoon.

The (optional but super fun) Friday night kick-off social will featured presentations by private sector and NGO leaders to focus developers on solving big issues in key sectors that align with the city's long-term sustainability plan, PlaNYC.

On Saturday morning, everyone met back at AlleyNYC for a briefing on API and datasets before beginning development of your apps.

Sunday, apps were be due at 1PM for judging which started at 2:30, and winners were announced around 4:30 pm. Presentations and awards were streamed live via Greentech Media and available for replay.

This event is part of the Cleanweb Hackathon Series that was started in San Francisco in September 2011 by Blake Burris and Sunil Paul and later mushroomed into a global movement with Cleanweb communities and events in cities throughout North America, the UK and Europe in 2012.
