What About Free Heat?

We’ve covered heating systems where you supply SOMETHING to make it work, electricity or fuel. What about systems that don’t need that? Can we get everything for nothing and can it be done at industrial scale? The Power of the Sun The sun is a massive, nuclear fireball, bombarding the Earth with numerous forms of radiation day in and day out. Nearly all the warmth on the planet comes from the sun. Even in the middle of winter, there is a TON of heat being blasted down on us. Just look at Pluto, which gets essentially no sunlight. It would make the ice planet Hoth look like Miami. This difference means that there is an abundance of energy, it’s just not enough to make the whole area toasty and warm. Air currents and shorter days reduce the total heat delivered and cause an overall lower temperature, but there is still a ton of heat. Think about it. If we have a large window into a well insulated room, the sun will heat that room up, regardless of the season. That’s without using any engineering to make it an efficient process. It’s just the natural conversion of radiation into heat. Thermal Engineering The most important part of a solar hot water system is to squeeze as much energy out of the sun as possible. This comes down to the design of the pipes in the rooftop component, a Thermosiphon, what they’re […]
