The event will take place at Sungevity’s headquarters in Jack London Square in Oakland, and will start at 5:30 PT, and run until Sunday evening. The hackers will spend 48 hours, supplied with pizza and Redbull, to build solar apps, and the best solar apps will win prizes at the end of the weekend. More info can be found here.

The “Cleanweb” is the trend of using information technology — software, the web, social media, mobile — to address resource constraints around energy, food and water. Sungevity founder and President, Danny Kennedy, tells me in an interview that they’re using the Cleanweb Hackathon thesis to build a community around trying to get more solar panels connected to grid infrastructure.

Kennedy is expecting between 50 and 100 participants and the Mayor of Oakland is expected to speak.

Sungevity uses the Internet and software to develop sales, marketing and financing for rooftop solar panel systems. The company was founded in 2007 and counts investors like Brightpath Capital Partners, Firelake Capital Management and Greener Capital.

This weekend 14 teams developed Cleanweb tools and we’re live streaming the presentations of these apps. In about an hour, a group of judges will choose their favorite Cleanweb tool and present the winners with cash prizes. I’ll do a wrap up of the events following the live stream as well. Happy watching:

The Awards!:

Best Overall: Team TACO

Audience award: Dr. Wattson

Twilio hackaward: The Freshlist App.

Sexy UI: Winner, Dr. Wattson. Honorary mention, Tomatoe.

Badass Hack: Winner, Tomatoe. Runnerup Toxic Slayar.

The Cleanweb Hackathon demos kick off!

1). GROmunity: The website brings together urban backyard farmers, in a part social network, part community, part economy. The most sustainable food comes from your backyard or the backyard of your neighbor, says the creator. GROmunity brings together backyard farmers in a network where users can barter, network, sell and buy food.

2). Tomatoe: An app that brings together data about energy, health and resources in different visualizations via states.

3). Greenly: A green life cycle analysis tool that small businesses and artisans can use to analyse and put on their green products. Judge Yves Behar says he likes the angle of putting the tool in the hands of the business or artisan, instead of a third party consultant.

4). toxicSlayar: An augmented reality layer to visualize toxic chemicals out there. The EPA collects this info, but its hard to visualize this data.

5). Task Turtle: Taskturtleapp.com. Crowd sourced tasks for food or cash. Smaller tasks, for smaller prizes, targeting homeless people, young people, senior citizens etc.

6). Commute Score: Bringing your commute into the energy equation. Crunching data from GPS cell phones to figure out trends about commuting.

7). Dr. Wattson: A web app that gives recommendations about your energy rates and bill. “Sleuthing out a better energy plan.” Uses Tendril API.

8). A solar investment analysis calculator: Using a variety of open source data about solar and energy, the team created a free tool to offer consumers an easy interface for learning how much solar would cost. They used the Genability API for energy data, Zillow API for solar array, open PV calculator cost for solar array, NREL for solar data, and open APIs for rebates for solar in California. Open source piece of code from David Anderson.

9). Energy Battle: Developers at Tendril, created Energy Battle, which is an iPhone app that uses Genability and Tendril APIs. A social game where you can do battle with other regions in the U.S. Social games applied to the energy space. Built to look like AIMFight. Working code now.

10). Get Tarzan: “Get stuff done, save time, money and CO2.” Trip planner/calender that includes info about sustainability and transportation in real time with traffic data. Can help plan meetings for more efficient transportation.

11). Team Taco: A Google Chrome extension that is pure java script. TACO, total cost of ownership. Used to publicize the overall cost of ownership, including lifetime of energy consumption, based on personal data, onto a retail shop’s website like Lowe’s. If you’re shopping for a TV or lawnmower, you can use the extension to see how efficient the product is.

12). GreenScore: Answering the question how green is your city, or your state? Uses data about pollution, traffic, fuel consumption, to make clear visualizations. Empower the common man to understand the greenness around him.

13). FreshList App: A way to sell anything at its most fresh. Mobile app where you text the word “help” to a phone number to find a local market place. It’s a mobile barter systems between buyers and sellers looking to sell and buy the freshest of food. Also there’s a forecast piece that takes GPS data to forecast when crop will be harvested. The tool is meant to help people find more sustainable food and help farmers buy a market.

14). Kijani Grows: Kijani is Swahili for the color green, website kijanigrows.com. Aquaponics is a way of growing plants and fish together in a highly efficient water recycling system. Using sensor data embedded in the aquaponic system you can connect with other sites like FreshList.

The Hackathon, the brainchild of investor and entrepreneur Sunil Paul, will bring together developers, UI specialists and business execs, to create usable Cleanweb tools over the course of the weekend. The teams will present their tools and Sunday and creators of the best tools will win prizes.

We’ll be checking out Paul’s kickoff talk and the overview of all the datasets compiled (there are a lot of ‘em) on Saturday morning, and we’ll be live streaming and covering the presentations and award ceremony early evening on Sunday. Paul’s group is looking to bring in inspired and talented developers who want to create Cleanweb tools.

Here’s a video of Paul’s talk on the Cleanweb at our Green:Net event earlier this year:
