That’s not a colostomy bag, it’s the first prototype of [Stephen’s] scratch-built closed loop personal cooling system. He must be living in an uncomfortably hot apartment as this is the second cooling ...

MARTHA’S VINEYARD, MA — This geothermal rescue was for a closed loop geothermal system that was seriously overheating during the cooling season. This system had ten vertical loops that served 11 heat ...

Steam is a marvelous way to transport large amounts of energy effectively and economically. That is why Steam has been the cornerstone of campus, district heating, and process systems for the past two ...

Today on Hackaday Dictionary, we’re going to talk about the two basic types of control systems: open-loop and closed-loop. We’ll describe the differences between them and explore the various ...

Researchers have used computer models of closed-loop geothermal systems to determine if they would be economically viable sources of renewable energy. They found that the cost of drilling would need ...
