How Effective is it Really?

You’re probably asking yourself, “how well does this really work?” In the tests shown in the YouTube video, the solar heater construction got up to 140 degrees Fahrenheit. The solar oven configuration created a temperature of 180 degrees. At this temperature, the water inside a black tea kettle reached 158 degrees. The solar oven was also able to cook perfect hard-boiled eggs without needing any water. Instant white rice cooked in 45 minutes, and a lentil stew cooked for five hours and reached an internal temperature of 165 degrees.

In other words, this thing really works! In fact, it works best as a solar oven, but with the solar fans attached, you can definitely warm up a room as well. This is an easy DIY option for going off grid or maintaining heat and the ability to cook during a power outage.
