In 1948, a physicist named Maria Telkes filled metal drums with a ten-dollar bucket of Glauber's salt and heated an entire house through a New England winter with zero electricity, zero gas, and zero moving parts. The physics was bulletproof. NASA still uses it. But the heating industry had other plans, and this technology vanished from every American home—except the Amish farmhouses where it's been quietly working ever since. I'll show you exactly what it is, why it disappeared, and how to use it to heat any room for almost nothing.

Glauber's salt is the common name for sodium sulfate decahydrate. It can be used to heat a home. it stores and releases latent heat when it changes phases from a solid to a liquid at a specific temperature.
How this works: Glauber’s salt has a melting point of 90.3°F (32.4°C), making it ideal for passive solar heating.Charging (Daytime): As sun shines through a south-facing window, the room heats up. Once the room reaches 90°F near the window, the Glauber's salt melts. During this phase change, it absorbs a massive amount of heat without getting any hotter itself. This keeps the room from overheating during the day.Discharging (Nighttime): When the sun goes down and the indoor temperature drops below 90°F, the liquid salt begins to freeze back into a solid. As it solidifies, it releases all that stored latent heat back into the room, keeping the space warm overnight.

Answers to the questions you're all asking:
• Thickener = attapulgite clay or CMC (carboxymethyl cellulose), 5–10% by weight.
• Borax = 3–4% by weight. It's the nucleating agent, it makes the salt freeze on time.
• Salt = Glauber's salt / sodium sulfate decahydrate, 40–80 lb per room. Buy it as "sodium sulfate" from a chemical or pool supply, $1–2/lb in bulk. The "$10" is a starter bucket, not 80 lb at retail.
• No basement needed — a sunny window or the side of your stove is enough.
