      • Electromagnetic > The Development of the Electric Motor - Credit for development of the electric motor belongs to more than one individual. It was through a process of development and discovery beginning with Hans Oersted's discovery of electromagnetism in 1820 and involving additional work by William Sturgeon, Andre Marie Ampere, Michael Faraday, Nikola Tesla, Thomas Davenport and a few others.

      • Wind > Horizontal Axis > Wind Energy Group - The WEGI-100 offers a variety of advantages over conventional wind generating systems. It is a low rpm, Bi-directional system. Horizontal blades and air baffles maximize the amount of wind velocity directed into the turbine allowing the system to capture more wind. The system can also operate under extremely high wind conditions. (Thanks John Q. Public)
      • Air Conditioning > TermoDeck - An air conditioning system using the building structure as an energy store of surplus heat, in the hollow core concrete floor slabs. The slabs are cooled with night air in temperate climates, or using conventional chillers in hot climates, but with up to a 50% reduction in required capacity. (Thanks John Q. Public)

      • Solar > Solar is the Solution - Steve Heckeroth argues that "our best and easiest option is solar energy, which is virtually inexhaustable. Most importantly, if we choose solar we don't have to wait for a new technology to save us. We already have the technology and energy resources we need to build a sustainable, solar-electric economy." (Mother Earth News; December 2007/January 2008)
