Abstract: A self-regulating vacuum still (8) has a fluid reservoir (10), a boiler (28), a vapor separator (46), a condenser (33), and a condensate reservoir (58). The boiler (28) receives fluid from the fluid reservoir (10) in liquid form and heats the fluid to generate fluid vapor, preferably using evacuated solar tubes (44). The vapor separator (46) receives the fluid vapor from the boiler (28) and separates entrained moisture. Preferably a packing (50) is provided by structured wire mesh which is disposed in a vapor outlet (49) from the vapor separator (46). The condenser (33) receives the fluid vapor from the vapor separator (46), and cools the fluid vapor to a condensate. The condenser (3) has a collection section (34), a condensate section (35) and an outlet (16) which is proximate to the collection section (34) and the condensate section (35). An airlock (20) is connected to the outlet (16) for venting air and fluid vapor from the condenser (33) when a preselected pressure is exceeded.

Abstract: A system and method for simulating lead of a target includes a network, a simulation administrator and a user device connected to the network, a database connected to the simulation administrator, and a set of position trackers positioned at a simulator site. The user device includes a virtual reality unit and a computer connected to the set of virtual reality unit and to the network. A generated target is simulated. The target and the user are tracked to generate a phantom target and a phantom halo. The phantom target and the phantom halo are displayed on the virtual reality unit at a lead distance and a drop distance from the target as viewed through the virtual reality unit.

Abstract: A method and apparatus are disclosed for sequestering carbon dioxide. Carbon dioxide and a reductant are fed into a combustion chamber and burned. The reductant forms an oxide with oxygen from the carbon dioxide, generating an oxidized reductant and carbon which are exhausted from the combustion chamber and separated. The oxidize reductant is then itself reduced to form reclaimed reductant, which is used to provide the reductant for reducing the carbon dioxide. The oxidized reductant is reduced by disposing the oxidized reductant in an inert environment and exposing the oxidized reductant to electromagnetic radiation of a wavelength for freeing oxygen from the oxidized reductant. The electromagnetic radiation is preferably provided by light having a wavelength which is readily absorbed by oxygen, such as light emitted by a YAG laser. Preferably the reductant is provided by a metal, such as magnesium.
