DIY Solar Thermal Water Heater: Free Hot Water For Life - This project is super simple and uses readily available materials, its the kind of things that could easily be scaled up to meet lots of hot water needs. If the power goes out this could produce hot water for showers and even heat a small room. This is a great way to have a cheap tank-less water heater system.

This project is super simple and uses readily available materials, its the kind of things that could easily be scaled up to meet lots of hot water needs. If the power goes out this could produce hot water for showers and even heat a small room. This is a great way to have a cheap tankless water heater system.

How does Solar Thermal work?

Solar thermal heating systems use solar collectors to capture energy to heat water.  There are many designs, however they all make use of the same working principle.  A singular liquid in the panels heats up and is pumped through a coil in the hot water heating supply.  Another approach is to circulate the water to be heated through the actual solar THERMAL panels.

Solar thermal technologies utilise the heat from the sun to off set the water heating demand of a building.  In general, the solar collector absorbs heat from the sun and transfers it to a working fluid (water of refrigerant), which is transferred to the water in a hot water tank either directly or via a secondary heat exchanger.

Solar thermal is a pre-heat system, due to the intermittency and seasonal dependency of the solar resource, additional heating requirement are supplied by a conventional heating source via a secondary heat exchanger.

Bonus: How to Make Pemmican, the Original Survival Food

Invented by the natives of North America pemmican was used by Indian scouts as well as early western explorers.

Native Americans spent a great deal of time on the go and depended on having portable, high-energy, highly nutritious, and filling foods that would last for long periods of time without refrigeration.

Pemmican is a portable, long-lasting, high-energy food. It's made of lean, dried meat that's crushed into powder and mixed with hot, rendered fat. This makes it one of the ultimate foods to have stockpiled for when SHTF or disaster strikes.

How To Make Pemmican: The Original Survival Food - If you're living through a disaster where you're on your feet a lot and don't have time to cook, one of the best foods you can eat is pemmican. It's packed full of fat and protein and can give you lots of steady energy throughout the day.

People really should avert their gaze from the modern survival thinking for just a bit and also look at how folks 150 years ago did it.

These guys were the last generation to practice basic things, for a living, that we call "survival skills" now.
