A Path to Energy Independence for Africa


     Leadership in Climate Change

         Africa’s historical commitment to renewable energy, particularly hydropower, is well recognized.
    Africa already generates a major part of its power from renewable energy.
     Many African governments are rapidly developing many new initiatives in energy innovation, energy efficiency and protecting the environment.
     Africa has the natural assets to be a leader in the use of alternative fuels.
     Africa nations are participating in international policy initiatives to address Global Warming.


Africa’s facing Energy Challenges

    The African economy is growing – the national generating capacity must be increased, according to the government.
     Escalating oil and coal prices as well as oil security issues are threatening to slow the African economy.
     Africa’s push toward renewable energy has been slowed by a number of problems.
     A lack of supply of wind turbines and a rise in turbine prices over the past two years due to rising materials prices.
     Rising PV prices and shortage of solar cell panels due to a shortfall of silicon.
     Increasing costs of large hydropower dam projects.
     Rapid urbanization and industrialization, uncontrolled environmental degradation and pollution are placing increasing pressure on the utilization of freshwater resources.


    Africa has its own Solution

         A significant amount of Africa is covered with rivers, lakes and wetlands.
         Africa is a major producer of hydropower.
         National hydroelectric schemes already contribute significantly to the national generating capacity.
         Africa has a large gross theoretical hydroelectricity generating capacity.
         Africa has used mini-hydropower plants for years.
         Africa has new hydropower dam projects funded and under construction.
         Africa also has large solar and biofuel assets.


        A New Energy Plan

         Use of unharnessed hydropower will quicken Africa’s energy revolution into a renewable future.
         GPW/AGD Energy’s hydropower technology will place river power generators in the largest number of sites in the shortest amount of time.
         They will be mass produced in regional automotive plants just like cars.
         They will be towed or trucked to the sites and placed in arrays in rivers and tidal flows to create integrated renewable energy powered girds.


        Concept: Harness Energy Along  the Length of the River

         Dams capture energy in one site.
         GPW/AGD Energy hydrokinetic technology (patent pending) harnesses moving water over and over as it flows down a river.
         Grid friendly – creates a power grid inside the river.
         The GPW RS Type 1 is an in-river power generator which operates in 4 knots or more of river current producing 50 kW. It has low visibility and is marine life safe due to low RPM operation. It can be placed on site and begin operating quickly. It is scalable for various river width and depths.
         The Type 2 is designed to be placed in residential and rural river sites of 1MW or more.
         The GPW RSBM is designed for population dense river areas. It operates totally underwater without the need for construction on the river bottom. It surfaces for annual repairs.
         A number of GPW RS-50s connected by a “suspension mooring harness” can be placed across a river to form power arrays without the need for costly, time consuming, and ecological damaging construction on the river bottom. A 1,000 ft by 1,000 ft section of river flow (4 knots) could produce up to 4 MW. A 1 mile section could produce up to 20 MW. (Equal to 80 MW of wind power (25% capacity rate.)
         GPW RS DW-50 is a self-contained unit designed to provide water and power to remote villages.       


         GPW RS SE-50 is designed to provide secure power for military bases and remote industrial sites.        


         GPW RS EN-50 designed to restore water quality in polluted rivers using an oxygenation process.       


         GPW RS CA-50 provides a compressed air network for factory and farm tools and machines.       


         GPW RS WM-50 provides potable water through the application of reverse osmosis technology.       


         GPW RS MP-2.5/5 is a self-contained, man-portable, small-scale 2.5/5kW unit.    


         GPW RS RE is designed to regenerate waste energy from established dam structures.   


        Problems to Solve



        Energy Solution

         Small power generators are placed in rivers, tidal currents and oceans.
         Units are connected in small arrays that produce 50 kW to large arrays producing hundreds of megawatts.
         Each power system operates quietly, cleanly, safely and almost invisibly.
         Produces energy quality (EROI, capacity factor, cost), equal to or better than fossil fuels.
         RS-High Density operates in debris strewn and iced over rivers.
         RS-Accelerator operates in slower speed rivers.    



         Each GPW RS-50 saves approximately $130,000 in annual fuel costs.
         Each system operates with minimal impact on surrounding humans and ecosystem.
         Each system is quick to install and operate cost-efficiently.
         Each system improves energy security of host country.
         Speeds rural electrification.
         Supports economic development in remote areas.        


        Water Solution

         All three systems can be modified to include an RO water maker integrated into the unit or installed        shore side.
         1 MW (20 units) GPW RS WM produce approximately 6400 gallons freshwater from brackish per day or 2,300,000 gals/year.       



         Approximately 50% of the cost/gallon of the RO process is energy.
         GPW RS brings affordable and clean water to Africa.
        Conservation Solution

         The GPW RS Developing World Series is composed of hybrid power/water maker GPW RS units that can be towed up river or trucked to a hydro-site and quickly set up to produce significant electricity for a village during the day and evening and then shift to refilling the village’s freshwater tanks during the night. 
         The GPW RS Environmental Series provides an energy free water restoration process that improves water quality promoting fish aquaculture, swimming, fishing and boating. The river’s own hydropower drives an on-board air-compressor which oxygenates the water improving dissolved oxygen and pH levels while killing off anaerobic and pathogenic bacteria.
         The GPW RS Wastewater Treatment Series is designed to provide a renewable energy source for riverside municipal waste treatment facilities. Energy is a major cost of these systems.
         Power blackouts can also cause these systems to fail and pollute rivers and lakes. The GPW RSTW also provides compressed air used for oxidation by these systems.     



         Each GPW RS-50 saves 32,000 gals of diesel fuel per year.
         Brings commercial development to remote villages.
         Cleans polluted rivers improving fish reserves.
         The GPW RS-AG is an array combining the GPW RS-50 to provide clean electricity, the GPW RS-CA to provide compressed air for farm tools and the newly developed compressed air engine powered tractors, the GPW RS-WP to pump water to irrigate the fields and the GPW RS-WM to provide clean water. Is designed for agricultural applications.
         Bring modern energy intensive farming to the Developing World which will help increase food supply.
         Help reduce fossil fuel emissions and waste stream for agribusiness.
         Reduce fuel costs for farms cutting overall food costs.
         Reduces risk of chemical and bacterial contamination.
         Africa will protect the environment while protecting the economy.
         Africa will offer companies going green a chance to reduce their future costs of energy and emissions as well as insure a more stable power grid.
         As fossil fuel prices rise Africa will gain the advantage of cheaper energy costs.
         It will promote Africa as a major user of global renewable energy technology.
         And it will help Africa achieve the low carbon generation regulations of the new green initiatives.
