Triple Hybrid Water Heater

The plan is to develop a refined HPWH optimized for a home with a PV system in three major ways not found on typical HPWHs. It is significantly more efficient than current HPWHs since it can extract heat from water as well as air, it can store low-cost energy to reduce use of higher cost energy,

TumbleDown Self-Turning Vertical Composting System

The TumbleDown Self-Turning Vertical Composting System repeatedly and thoroughly mixes ("turns") compost without machinery or labor. The design resembles a multiple helix spiral staircase within a silo. The mixture of organic materials tumbles down from one stairstep to the next. “Self-Turning” refers only to the spontaneous tumbling of the compost.

TURBINE with Jet Incision and Turboexpander

This turbine differs that has two additional elements - a turbo-expander in the center and jet cuts on blades. The turbo expander absorbs wind energy. Thus the non-working center of the turbine becomes effective. In some versions, the fairing itself will have grooves absorbing wind energy.

Vacuum Assisted Radiant Cooling

Air-conditioning systems spend most (up to 90%) effort on cooling air. Cooling people is just a byproduct of the whole process. To reduce energy demand we need to implement approaches that reverse this situation and focus on directly cooling people with minimum conditioning of surrounding air.

Based on the ASHRAE Standards,
