    • Solar powered battery charger 

      Dudley, Jonathan; Krouth, Sheila; Loudon, Michael
      Solar arrays provide clean power, but the amount depends significantly on available sunlight. To achieve sufficient power, mechanical tracking or maximum power point tracking (MPPT) methods are implemented. While mechanical ...
    • Solarizer 

      Brandt, Michael; Green, Michael; Pearce, Shelby; Soileau, Liana
      In developing countries and following natural disasters, there is a need for a portable solar powered autoclave to properly sterilize surgical equipment because there is often no access to electricity or natural gas. Without ...
