North Star Devices is a private company located in St Paul, MN. It is a charter member of Solar Solutions Team. The company has developed the popular Water Pasteurizer Indicator or WAPI. It is now developing a Solar Pasteurizer for use in poor countries and during emergencies in other countries. Although designed for the tropics, it can be modified to work at higher latitudes.
CLEAN WATER
Polluted drinking water causes more death and disease than any other vector. It also causes malnutrition in people that are getting enough food for normal health. This is because food is being used to combat germs rather than provide energy.
The ideal solution to this sanitation issue is to drill wells. Organizations like World Vision are doing a remarkable job of drilling wells all over Africa. See www.worldvision.org. Organizations like Compatible Technology supply plans for equipment that dispenses chlorine to purify drinking water. See www.compatibletechnology.org
A third alternative uses the ultra violet and/or the infra red rays in sunshine to purify water.
Mr. Bob Nepper and William Stevenson of North Star Devices Inc. are the producers of a Water Purification Indicator or WAPI. It is a clear plastic tube with a daub of wax inside. This is a mixture of varieties designed to melt at about 150F. This is the temperature at which germs are killed by heat. About 90,000 have been sold to people in poor countries.
They have also designed and built 6 copies of a Solar Water Pasteurizer. [SWP] Polluted water is first filtered and then passed through this device to kill the germs. It was designed for use in the tropics but could be reengineered to work well in moderate climates.
These 6 units are working very well and could be replicated for more universal use. A new and better way of fabrication has been discovered. It is a machine for plastic welding. Using this machine would reduce the product cost from about $200 to about $100.00.
The purpose of this crowd funding effort is to solicit funds to do the following:
1. Improve the design
2. Purchase a Plastic Welding machine.
3. Develop user and fabricator instructions
4. Team up with an established organization like World Vision to distribute these devices where needed.
5. Begin fabrication of more Solar Pasteurizers.
The total amount of money being sought is $5,000.00?
BREAK THROUGH! - Low Cost Solar Pasteurizer
· Uses only the sun – No electricity, batteries chemicals or fossil fuels
· Up to 4 gallons per hour (in good Minnesota sun)
· No wood to warp, split or decay
· Kills dangerous pathogens in contaminated water automatically
· Designed for simple construction in user countries – Jobs for local population!
· Sized for airline baggage –- 83” X 25” X 4” (33 lbs swt.)
· No expensive copper tubes to invite theft
· Thermostatically controlled to above 160F – safely above pasteurization temperature of 149F (65C)
· Developed by retired 3M engineers, William Stevenson and Robert Nepper
