Abstract: A device to protect a user from inhaling hazardous atmospheres including an insulated chamber having inlet and outlet. The chamber includes air heating means and air UV radiating means. The combined operation of the air heating means and the UV radiating means is configured for disinfecting the hazardous atmospheres. A cooling means is used for cooling the disinfected hazardous atmospheres. Wherein, the cooled disinfected hazardous atmosphere is then delivered to the user's breathing system.

Abstract: A wind energy device (100) utilizes a cone (102) to concentrate the wind. The inside of the cone (102) has rifling (110) which spirals the wind to more effectively hit the rotor blades (112) adjacent the smaller opening (108) of the cone (102). A convex screen (124) deflects objects from the larger opening (104) of the cone (102). The device has a bottom caudal fin (116) to help direct the wind into the larger opening (104) of the cone (102) as the wind changes direction. The cone (102) can have a top fin (118) as well. The device is equally weight balanced on a shaft (120) and pivots on a bearing (122) to help it rotate effortlessly. This pivot enables maximum efficiency of capturing the wind. The cone (102) can be comprised of sections (136) that open up in a strong wind by hinges (134) and a motor or spring at the front (104) of the cone (102). Solar panels (132) can be placed on the cone (102), the rotor housing (114), the generator (126), and the shaft (120) to generate additional electricity.

Abstract: A thermoelectric unit including thermoelectric modules, cold side fins, a heat sink, a hot side heat absorption element, and an electronic controller. The heat absorption element includes a metal heat transfer structure, phase change material (PCM) and heat exchange medium.
