In Korea, you can get just about anything delivered -- from food and groceries to furniture and household appliances.
And soon, you can add heat to the list.
That's after Hyundai Steel Company, Korea's second-largest steelmaker, completed a trial run of a new heat delivery system that transports waste heat.
During the trial, heat was captured from blast furnaces which are used to melt iron at steel mills.
The heat was then transferred onto a five-ton truck that delivered the recycled energy to a local food waste facility for use as a power source.
Just one of these trucks can hold enough heat to supply power to five households for up to 10 hours.
"Our technology focuses on two things: restoring the heat energy in a short amount of time and delivering it to our clients quickly and at a consistent temperature."
To make sure the heat stays at the same temperature during transport, researchers equipped the truck with an alumina container.
The heat delivery system is being seen as a positive business model for Korea that could also help the environment.
By recycling heat that would otherwise be lost in the air, researchers say the system could significantly reduce carbon emissions and cut the cost of raw materials by more than 90 percent.
In the short-term, Hyundai Steel plans to expand its heat delivery network to facilities within a 40-kilometer radius from its steel factories.
