Robert Nepper is involved with the Rotary club in a project to manufacture thousands of Water Pasteurization Indicators (WAPIs) for use in projects throughout the world. This has lead to the creation of the company North Star Devices.
- August 2017: New products in development - Robert Nepper announced that North Star Devices has created a floating water pasteurization device known as the SPORTSWAPI 2, and have refined their solar water pasteurizer. The company is currently seeking interested investors. See the North Star Devices solar pasteurizer brochure.
- January 2014: North Star Devices announces a sale on the SuperWAPIs. A year-end sale set to end on December 31, 2013, is to be extended until remaining stock is gone. Regularly $225USD for 100 finished units, the price is now $199USD including extended financing options. Read about the WAPI's latest features: Reusable Water Pasteurization Indicators (WAPIS)
- December 2013: Robert Nepper reports that they have made improvements to the SuperWAPI, which features a heat resistant stainless steel cable.
