Saran Renewables - sustainable biomass CHP

I want to tell you about the Saran Renewables projects in India. I heard about them on the Community Channel because they won an Ashden Award last year. They are using sustainable sources of biomass to produce a reliable supply of electricity a fixed number of hours a day.

Wood or other biomass goes into a gasifier to be converted into burnable gas and this is cleaned up through chemical processes onsite. The cleaned gas is then fed into a gas turbine which produces electricity.

"The biomass comes from ‘dhaincha’, a local woody plant which can be easily and profitably grown by local farmers. The generator connects to transmission lines to supply small businesses with electricity for a guaranteed 11 hours a day." from here.

This is a really simple clever idea and it struck me that it's great for places without much wind, tidal, hydro or solar potential. It's important not to cause food shortages by turning over land that could otherwise be used for food production to biomass production - but if the land is not suitable for food production anyway, this can be a great use.

There's an exciting local development near us - we have some ancient woodlands in the place where I live. There's a regeneration plan for the area and I started wondering if we couldn't do something similar with the timber products from managing the woodland. I asked a few people and discovered that a CHP plant using the biomass from this area and the neighbouring area has been sketched into our neighbourhood development plan. I mentioned it in my IMAGINE1 post.

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.

Where I will be in ten years.

Ten years from now I will be in a political job assisting with people in the midlands of South Carolina particularly the rural working class and farmers. As the class of people that feed the nation I find that it is imperative that we assist with making sure they produce as much food as possible. I would like to support local scientists as well that are leading in research on how to produce food more efficiently. I will also be participating in missions to foreign countries to help people with…See More

Changes to Charleston

Included are new emergency routes on what will be an expanded highway to allow traffic to flow in the event of an emergency.See More

India Water home

The secret was living on the water via boats common in many developing countries like Myanmar. This is a real Indian boat home made of wood and this provides a shelter for many peoples around the world.
