Better design for PyraTENT: why creating an in-ground water pond is critical in storing solar heat

We use several images including infred imaging for the passive China greenhouse to explain why using the entire ground as a water pond with pond liner is critical in containing solar thermal heat in water, the best thermal mass for heat storage.

This time we present a PyraTENT designed for areas that do not have freezing conditions in winter time. In this case, it is possible to use water alone to modulate temperature and humidity in a POD like structure equiped by a double-layer envelope.

Since obtaining PhD in Electrochemistry in 1994 (University of Calgary), I have been through many things, such as post-doctoral research work using STM to study atomic level electrodeposition of Cd on Ag(111) surface at UIUC (Urbana-Champaign at University of Illinois), lifetime free-lance preaching, CEO of TheoLogos Publications and PyraPOD Global Inc, former salesman of diamond tools for Superprem Industries, former director of DiaSolid Kitchen & Bath, finishing carpenter, working for CRE Green, a solar company in Kelowna, BC. After all these experiences, my life motto is this: sharp mind must combine with skilful hands. With my wife Margaret we have three kids - Riley, Grace and Anita.
