Card On Guard

Card On Guard is a thin and self-sustaining solar cell that
captures, stores and reemits UV and Infrared light from
either natural or artificial sources and inhibits bacterial
and fungi growth. No electricity required. Replacing 50%
- 100% of traditional chemicals, the product has won the
2015 Technology Innovator, Emerging Technology
Awards 2015, Big Innovation 2015 and Red Dot 2016
awards. The design is intended to be as functional as it is
attractive by providing maximum direct contact with both
light and water. The card is held upright in the water by a
set of internal weights and floats so both sides are
exposed to sun and other light and it is moved through
the water and around the pool by the "shark fin" design
that allows it to catch moving air and wind.
