Grass Biofuel Pellets: “The need to find alternatives to fossil fuels and reduce Greenhouse Gas emissions has peaked interest in biofuels by energy specialists around the world. REAP-Canada has pioneered the research and development of biofuel pellets made from switchgrass (Panicum virgatum) for use in space heating applications. Switchgrass, when pelletized, has considerable potential to displace oil, natural gas, and electricity used for heating fuel. This development can significantly reduce greenhouse gases and heating costs and sustainably assist the development of rural communities. Fast growing warm season perennial grasses have been identified as ideal candidates for biomass fuel production due to their high net energy yield per hectare and low cost of production.

A house powered by spinach: “Seattle architecture/design firm Mithun won first place in the C2C Home Competition with their design for a house powered by spinach. The house will be built this summer in Roanoke, Virginia, along with other contest winners.
The competition asked designers to work on work on cradle-to-cradle design principles and create objects and processes that replenish communities, using materials that can be recycled indefinitely.
Mithun’s house takes energy from the sun and uses spinach protein to generate electricity for neighbouring homes and street lighting infrastructure.
The house’s skylight brings in the sun’s rays, and the heat sink stabilizes temperatures, while a highly conductive material produces photosynthetic energy generated from the protein in spinach. The spinach proteins are sandwiched between the core’s glass walls; their chlorophyll converts the sun’s rays to fuel the home. Besides, a vegetated roof system collects and filters stormwater into the building core
