Phase-Change Thermal Plant Dome

Phase-Change Thermal Plant Dome Inventor: Kirk Lim Sang This invention is an automatic thermal battery dome built to protect vulnerable backyard crops and young garden plants from freezing winter weather. The system functions completely on natural outdoor elements without requiring electrical cords, solar setups, or replacement batteries. The device works by using a clear double-wall structure filled with a special chemical mixture made of calcium chloride hexahydrate, during sunny afternoon hours, the dome material absorbs solar heat which causes the internal chemical mixture to melt into a liquid state, when the sun sets and temperatures drop toward freezing, the trapped liquid hits its engineered phase-change point, as it cools, the mixture releases a massive amount of latent warmth while turning back into a solid form, this process keeps the internal air locked at a safe, gentle temperature between seventy and eighty degrees Fahrenheit for up to twelve hours straight, the dome blocks cold air from reaching delicate leaves while keeping the plant safe and warm through the bitterest nights. This creation helps humanity by improving local food security, extending short farming seasons for home growers, and reducing the reliance on greenhouse heating fossil fuels; it empowers families to grow fresh produce closer to home during harsh winter months, lowering food transportation costs and helping the environment.
