here are some of the 1400 inventions from nasa that help people and industry in the united states as per
WWW LinkTop Left: Athletic shoe design and manufacture also benefited from Apollo. Space suit technology is incorporated into a shoe's external shell. A stress free "blow molding" process adapted from NASA space suit design is also used in the shoe's manufacture.
Top Right: Freeze-dried food solved the problem of what to feed an astronaut on the long-duration Apollo missions
Bottom Left: Insulation barriers made of aluminum foil laid over a core of propylene or mylar, which protected astronauts and their spacecraft's delicate instruments from radiation, is used to protect cars and trucks and dampen engine and exhaust noise.
Bottom Right: Water purification technology used on the Apollo spacecraft is now employed in several spinoff applications to kill bacteria, viruses and algae in community water supply systems and cooling towers. Filters mounted on faucets can reduce lead in water supplies.
Top Left: Process for bonding dry lubricant to space metals led to the development of surface enhancement coatings, which are used in applications from pizza making to laser manufacture. Each coating is designed to protect specific metal group or group of metals to solve problems encountered under operating conditions.
Top Middle: Digital signal-processing techniques, originally developed to enhance pictures of the Moon for the Apollo Program, are an indispensable part of Computer-Aided Tomography (CAT) scan & Magnetic Resonance Imaging (MRI) technologies used today worldwide.
Top Right: Vacuum metallizing techniques led to an extensive line of commercial products, from insulated outer garments to packaging for foods & from reflective blankets to photographic reflectors.
Bottom Left: Cordless power tools & appliances are one of the most successful commercial spin-offs of space-based technology.
Bottom Middlet: Cool suits, which kept Apollo astronauts comfortable during moon walks, are today worn by race car drivers, hazardous area workers, & people with specific health problems.
Bottom Right: A hollow retroreflector, a mirror-like instrument that reflects light & other radiation back to the source, is used as a sensor to detect the presence of hazardous gases in oil development, chemical plants, waste storage sites & locations where gases could be released into the environment.
Top Left: Kidney dialysis machines were developed as a result of a NASA developed chemical process that could remove toxic waste from used dialysis fluid.
Top Right: As a medical CAT scanner searches the human body for tumors or other abnormalities, the industrial version, or advanced computed tomography inspection system, finds imperfections in aerospace structures and components, such as castings, rocket motors and nozzles.
Bottom Left: A cardiovascular conditioner developed for astronauts in space led to the development of a physical therapy and athletic development machine used by football teams, sports clinics and medical rehabilitation centers.
Bottom Right: A hospital food service system employs a cook/chill concept for serving food.
after reading about just the cat scanner tell me that the money being spent by nasa is a waste
