Engineering and design capabilities are exceptional because of:

• Firsthand design and manufacturing experience as a machinist and welder since 1963.

• Field experience (installation, maintenance, and repair) with the products under design.

• Strong research, design and laboratory experience.

• Biology background facilitates environmental and human factors engineering.

Leaving college, Mr. Sams started a company; Proko International (1976-1982).
This corporation specialized in designing and marketing recreational products.  Proko would support its overseas suppliers with technology, market information, raw materials, and tooling.  Proko would then have exclusive access to these products for sale within the U.S. Product included: Minolta binoculars, thermoelectric refrigerators, Novurania inflatable boats, and diesel generators.

In 1979 Mr. Sams teamed with David Lehmann and formed Polar Products.  The direction was to manufacture and distribute solar powered refrigerators.

For growth, Mr. Sams pursed other special aerospace and military cooling and power system requirements. Eventually, these cooling and power applications over-shadowed the solar refrigerator activities and the company re-organized into Polar Power, leaving the solar refrigerator tooling and production with Mr. Lehmann and his company, Sea Freeze of America.
