Concept Lab
Grounded engineering concepts for systems that don’t quite exist yet. Each study separates what’s proven, what’s theoretical integration, the real numbers, and the obstacles between an idea and a product.
What Concept Lab is: speculative engineering studies, clearly labeled and kept separate from our verified build guides. The components are real and the math is checked; the fully integrated products described are not yet things you can buy off a shelf.
The Solar Thermal Router
Could one solar-powered AC cool the house while heating the water, drying clothes, and warming the pool? A five-ton AC dumps 20+ kW of heat while it runs. We ran the numbers on catching it instead of throwing it outside.
Read the study →The House as a Thermal Battery
Using the building’s own mass, water tanks, and phase-change materials to shift heating and cooling loads off peak — how much storage actually hides in an ordinary house?
Coming soonThe Direct-DC Home
What if the panels, batteries, and biggest loads never converted to AC at all? Counting up the conversion losses a fully DC house would skip.
Coming soonSeasonal Heat Storage
Storing summer heat until winter. The physics that makes it possible and the volume problem that makes it hard.
