The smart thermal battery that captures sunlight by day, releases warmth + circadian light by night
You come home at 7pm in January. No programming, no switches — your living room is already a perfect 70°F and glowing with warm amber light that slowly deepens over 90 minutes. You feel your shoulders drop. Your house didn't just heat itself — it gave you back the sunlight it watched all day.
Installs in your sunniest window. Phase-change material absorbs excess heat during peak sunlight hours.
Automatically releases stored warmth as temperatures drop at sunset, cutting heating bills by up to 40%.
Circadian-synced lighting shifts from warm amber to deep sunset hues, helping you wind down naturally.
