Monolithic dome office
Monolithic domes are constructed following a method that requires a tough, inflatable Airform, steel-reinforced concrete and a polyurethane foam insulation. Each of these ingredients is used in a technologically specific way. This technology was developed by the Monolithic Dome Institute (MDI). The domes can be designed to fit any architectural need: homes, cabins, churches, schools, gymnasiums, arenas and stadiums, bulk storages, landlord dwellings and various other privately or publicly owned facilities. The dome, when finished, is earthquake, tornado and hurricane resistant (FEMA rates them as "near-absolute protection" from F5 tornadoes and Category 5 Hurricanes).

MDI has also developed the technology to build so-called "EcoShells". These are simple structures to provide for the basic needs of a family. They are designed specifically to answer the needs of shelterless people worldwide. They are strong structures that can withstand natural disasters, fire, termites and rot. In underdeveloped areas with hot climates, EcoShells make affordable, low maintenance, sturdy housing. In industrialized nations, EcoShells make superior workshops, garages, storage sheds, etc.

Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available renewable energy on earth. Only a minuscule fraction of the available solar energy is used.

Solar powered electrical generation relies on heat engines and photovoltaics. Solar energy's uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, solar hot water, solar cooking, and high temperature process heat for industrial purposes.To harvest the solar energy, the most common way is to use solar panels.

Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.
