You need to know up front that you won't find any better source of solar inventions anywhere. Vast numbers of regional jobs can be created and the entire fossil fuel industry will eventually be flattened. Each solar improvment lowers the cost of renewable energy. Every time that the cost of renewable energy is lowered, an oil field goes undrilled or a gas well goes unfracked. It's a virtual certainty that small groups of individuals or one single community can lower the costs of renewables. The only questions are who, when and can you participate. We're focusing 5x normal sunlight through our windows. We put extra sun on the tomatoes and we lose very little heat at night. Nobody else on earth can do this! OUR UNIQUE KSD SOLAR GREENHOUSE DESIGN PACKAGE FOR FARMERS, FOR BUILDERS AND FOR SCHOOLS OR COMMUNITY GROUPS IS READY! **Farmers can build the greenhouse themselves with our assistance; provide local food in winter, and save thousands of dollars in construction and in heating costs.

Most recently, we are offering schools and community groups similar options to build and use the greenhouse for curriculum and/or food production.
