Abstract: A very low pressure and entirely mechanical sea water desalination device is described, which may be built and operated at a fraction of the current costs for the desalination of sea water. The desalination device is used to purify polluted or otherwise impure water and is a device is easily scaled and can be used in a very small facilities up to the largest facilities for desalinating or purifying water. The device operates with sunlight and ambient heat, and therefore will be very inexpensive to operate in desert and tropical regions; and slightly more expensive to operate in cooler regions, yet still substantially less expensive than the existing systems. The device reduces the cost of potable water made from sea water or other polluted sources to a level which is comparable to or less than the cost of such water received from traditional local fresh-water sources.

Abstract: A manufacture or composition of matter for impact mitigation and injury prevention when used as elements of a helmet for football and other sports, or in other similar impact mitigation situations, which protects the wearer from concussions and other injuries by providing a soft and flexible yet very strong outer surface, and a gel or other viscous interior, held in place against the head of the wearer by the same or a similar yet softer material as on the outer surface; and a helmet which does not have earholes and uses an electronic means to transmit sounds.

Abstract: A very low pressure and entirely mechanical sea water desalination means is disclosed, which may be built and operated at a fraction of the current costs for the desalination of sea water. The said means can also be used to purify polluted or otherwise impure water. Arrays of the means are scalable from a very small facility up to the largest facility which may be possibly constructed and operated. The operation of the means relies on the presence of sunlight and ambient heat, and therefore will be very inexpensive to operate in desert and tropical regions of the world; and slightly more expensive to operate in cooler regions of the world, yet still substantially less expensive than the existing systems. The entire purpose of the invention is to reduce the cost of potable water made from sea water or other polluted sources to a level which is comparable to or less than the cost of such water received from traditional local fresh-water sources.

Abstract: A protective and attractive garment such as a jumpsuit is provided which has the appearance of a normal article of clothing. The garment is particularly suitable for hang-gliding or parachuting and is made from a fabric of two coextensive layers of close-weave material which offers substantial resistance to the flow of air or gas through the material. If an emergency arises which exposes the wearer to the danger of an injury due to forceful impact, the suit is inflated by providing a gas under pressure to the area between the two layers of material thereby surrounding the wearer with a protective air cushion.
