摘　　要：Main sources of renewable energy in the tropics are solar thermal and biomass.High-performance concrete(HPC)allows prefabrication of stakes,planks,boards,U-,L-,and I-profiles,prestressed thick-wall cylinders,and arc sectors.They are used to construct fences,level curves,buildings,contention walls,water and anaerobic tanks,and silos.Biomass production is increased by retention of rain water in the soil by level curves,in riparian tanks,and with fertigation.HPC anaerobic digesters produce biogas,biochar,and liquid fertilizer.Biogas is partially washed in medium-pressure vessel to obtain vehicular methane gas,which is partially burned in engine generator sets,whose combustion gases are fed into a boiler of a thermoelectric unit.The cycle is thermal solar regenerative Rankine cycle with heat recovery.Boiler receives hot water from thermal solar parabolic collectors,burns residual biomass and biochar generating steam for a turbogenerator set and combustion gas for condenser dryer silo,whose exhaustion heat goes to anaerobic digesters.
