How much CO2 would be eliminated if every concrete supply chain in the world delivered a minimum of 3000psi concrete? When poor concrete practices produce weak structures they crumble and must be replaced. Rework requires more CO2 producing effort and materials. Since concrete is the second most consumed product on the planet, we should focus on only making it once.

The rivers in mountainous to hilly terrain has very good velocity at surface ranging about 1.5 to 3 m/s which if could be extracted in a section of a river using a series of micro floating turbine could generate enough amount of energy for a rural community. If these turbines can be made floating and by using few locally used material and easily operable can change the life of millions of peoples living in rural areas. The river routed road can be lighten with this power production also.
