Inhabitat has published the 20 finalists in its ReBurbia suburban design competition. Some of my favourites include: 

Regenerative suburban median: Within many suburban developments there is an abundance of under utilized space within residential lots and public rights of way. Many suburban streets are 35-50ft wide; such widths unnecessarily consume ecological, social, and economic resources. We propose a new regenerative median for suburban streets that treats gray water and sewage, produces agriculture, provides a platform for small scale commercial activity and slows down automobile traffic to promote increased pedestrian activity and social interaction within the neighborhood.

Ex Box: There is a movement of reusing abandoned malls for community spaces. EX-BOX will allow the building to be self-sustaining by providing energy and space for public events. It provides renewable energy by maximizing the solar exposure with the use of various angles. By plugging in the programs that add density to the empty space and provides better environment, the space will bring people and allow community events.

Entrepenurbia: Rather than taking the traditional, additive approach to solving problems, the Entrepreneurbia model simply abolishes poorly conceived zoning laws to attract forward-thinking small business owners and start-up companies. The result is a community of entrepreneurs who transform inefficient single-family dwellings and purely decorative landscape spaces into intelligent home-based businesses.

C3 Initiative: The C3 initiative will “re-colonize” suburbs by adding localized and micro versions of retail, energy generation, water efficiency, community organization, and economic development. C3 colonies utilize existing/built environments but look inward and generate energy, water conservation, community and revenue as a sustainable micro-society.

 

The Guardian reports on attempts by scientists to mimic the energy-producing abilities of plants:

Now scientists developing the next generation of clean power sources are working out how to copy, and ultimately improve upon, the humble leaf. The intricate chemistry involved in photosynthesis, the process where plants use sunlight to convert water and carbon dioxide into sugar, is the most effective solar energy conversion process on Earth. And researchers believe that mimicking parts of it could be the ticket to a limitless supply of clean power...

...At Imperial College London, researchers have embarked on a £1m project to study, and eventually mimic, photosynthesis. Part of a project called the "artificial leaf", involves working out exactly how leaves use sunlight to make useful molecules. The team then plans to build artificial systems that can do the same to generate clean fuels such as hydrogen and methanol. These would then be used in fuel cells to make electricity or directly to power super-clean vehicles.

Similar projects are gathering pace around the world: the US is poised to approve a federal research budget of around $35m a year for ideas that could create fuels from sunlight and the Dutch government has allocated €40m for similar research.

According to James Barber, a biologist at Imperial College London and leader of the artificial leaf project, if artificial photosynthesis systems could use around 10% of the sunlight falling on them, they would only need to cover 0.16% of the Earth's surface to satisfy a global energy consumption rate of 20 terawatts, the amount it is predicted that the world will need in 2030. And unlike a biological leaf, the artificial equivalent could be placed in the arid desert areas of the world, where it would not compete for space agricultural land.
