Mastodon

Winner: Best Hack and Peoplefund.it Prize

The judges say:

Mastodon looks to the future of distributed computing, and is a great example of web-meets-cleantech.

Links

http://www.mastodonc.com/

Description

Don’t let your cloud computing become hairy, lumbering, and extinct. Use Mastodon C to select the most efficient and sustainable location for your job. Continually calculated and updated, to give you the confidence that your data crunching won’t destroy the planet.

The financial cost and carbon cost depends on:

  • Live costs from cloud providers right now
  • Current energy mix at each location
  • Current temperature at each location (low temperature means less cooling needed, so less energy used per operation)

Nanode Ambient Energy Display

https://gist.github.com/1704231

Description

A hardware hack to a Rainbowduino 8×8 RGB matrix display allowing it to display power consumption data as big bold colourful graphics. Data received wirelessly from the Open Energy Monitor EmonTx. Ideal for old folks or visually impaired who may struggle with digital display devices.

One Tonne

Winner: Visualisation Prize

The judges say:

One Tonne was a clear and simple idea that was the most likely to be used and forwarded on to friends. We also liked that “yurt” was listed as a dwelling.

Description

We took one tonne as a memorable round number for the personal carbon footprints we may need to aim for. The question then is.. how much fun can we have for a tonne?!

The benefit of thinking about it this way round, as opposed to many current carbon awareness initiatives which focus more on ‘where we are now’, is that we start to get a feeling for where we need to get to.

Includes search via Ask AMEE.

Play4Decades

http://play4decades.herokuapp.com/

Description

Multi-player simulations can be powerful tools for teaching in classrooms by allowing students to collaborate using a network of devices and displays. For example, the 4Decades Climate Leaders game has been successful in engaging managers in discussions about global climate policy.

However, there currently aren’t any online game engines or frameworks that specialise on this kind of distributed, co-located real-time game play. Custom solutions are difficult to engineer and are often limited to local networks or special hardware. This project set out to build a web-based framework that makes games like Climate Leaders accessible to a large audience around the world, using commonly available, browser-based technology.

Realtime National Grid

http://www.zangtumbtumb.com/nat_grid/

Description

This hack generates a visualisation of the current fuel mix of National Grid electricity. It displays:

  • Fuel mix
  • Current National Grid Power (in GigaWatts)
  • Current National Grid emissions (in tonnes CO2 per second)
  • Current carbon intensity (in grammes CO2 per kWh)

The hack was inspired by: realtimecarbon.org and uses data from here.

The idea is that people have a very poor sense of how their electricity is made. Being able to see how much of our electricity comes from coal and gas and how little comes from renewable sources are used may help people to engage politically to change electricity production.

In the future a similar visualisation may support attempts to develop load balancing applications with meaningful impact on carbon emissions.

The idea of the style of the visualisation is that it is supposed to suggest several streams of different width coming together to make up a single electricity cable. It’s a quick and dirty hack and needs cleaning up visually.

Retrofit

http://github.com/openenergymonitor/retrofit

Description

Retrofit is a tool to explore the effect of different retrofit measures. Starting with a basic model of a house, its possible to explore the implications of adding a given thickness of insulation and improving draught proofing, including predicted energy demand and financial payback.

The next step is to integrate this tool into the larger community energy plan maker application that we have been developing as part of the openenergymonitor.org project.

Carbon Emissions in Minecraft

A mod for Minecraft that adds carbon emissions using AMEEconnect to get real scientific data from the IPCC. When you burn some wood in a furnace, the mod calls out to AMEEconnect to do a calculation, and adds the result to a tracker in-game. As the carbon ticks up, the environment gets more and more polluted as the skies go dark and the clouds come down.

Hackers: James Smith
