PolyPlus's battery may be just that: Dip the encapsulated lithium pack into a glass of
ordinary water and it produces current that lights up an LED
display at the company's conference showcase booth.
The exhibition also includes First Aid: Homage to Joseph Beuys (1969 — 2017), a
display of first - aid cabinets containing miniature phials filled with
water taken from holy wells and streams, which references both Beuys's ability to endow
ordinary materials with sacred values and the potential healing power of art.
