Discover low-tech, high-impact off-grid innovations that use physics and sunlight instead of electricity. This course covers hydraulic ram pumps, solar chimneys, thermal batteries, wicking beds, and solar stills — practical designs that build comfort and resilience naturally.
Master the art of DIY renewable design. This course explores simple, powerful off-grid systems — from solar cookers and condensation stills to phase-change storage and wicking beds — turning sunlight and gravity into self-sustaining comfort.
