“How can we carry waste heat to an end user?”
We have a problem. Residential communities often require heat for their everyday needs. But for each building to have their own heating unit would be very difficult, costly, and inefficient. So how could we use our engineering mindset to solve this problem? Well, what if we were to have a central energy generation location that would heat up fluids which would be transferred throughout a network using insulated pipes? Well, this is the idea behind district heating and is used to warm homes everywhere.
