"coconuts, lemons and modified wood heat and cool home, greenhouse... 100 kg save 2.5 kWh/ day heating or cooling given 24°C ambient temperature... coconut molecules can transition from solid-to-liquid which absorbs energy; or from liquid-to-solid which releases energy... removing lignin from wood opens pores in wood cell walls...  Limonene acrylate transforms into bio-based polymer when heated, restoring wood's strength and allowing light permeation; molecules trapped so energy storage and release"
