E 15
The E15 is a totally self-contained 40 psi ellipsoid underground disaster shelter designed to protect 15 adults for long periods or 25 people for short durations such as during tornadoes.  The product was specifically designed and developed to protect  people during and after disasters such as tornadoes, hurricanes, earthquakes, storms, forest fires, power failures, nuclear power plant accidents, nuclear/chemical terrorism, and full-scale protracted nuclear, chemical and biological war.  A tremendous effort has been made to think of every conceivable incident that shelterists could face in the E15 shelter.  Many geometrical shapes were experimented with before finalizing the E15. The E15 includes the fiberglass ellipsoid structure, fiberglass entranceway with stairwell, fiberglass/composite hatch, MCAS-80 air filtration system, 120 gallon fiberglass septic tank, 1000 gallon internal water tank,  fiberglass floor, fiberglass counter, fiberglass shower wall, fiberglass battery housing, toilet, floor, twenty four 12- volt deep cycle batteries, gray water tank,  all wiring, all plumbing, etc.  The E15 requires approximately 1 man-hour to connect the entranceway to the shelter.
