A geothermal heat pump or ground source heat pump (GSHP) is a central heating and/or cooling system that transfers heat to or from the ground.It uses the earth as a heat source (in the winter) or a heat sink (in the summer).eat pumps can transfer heat from a cool space to a warm space, against the natural direction of flow, or they can enhance the natural flow of heat from a warm area to a cool one. The core of the heat pump is a loop of refrigerant pumped through a vapor-compression refrigeration cycle that moves heat.

Milky Way from Missouri Mountain, Collegiate Peaks Wilderness, Colorado. âWhen the spring of 2013 began I had fourteen Fourteeners to go in my seven-year Sunrise from the Summit project.

The Milky Way is a barred spiral galaxy, about 100,000 light-years across. If you could look down on it from the top, you would see a central bulge surrounded by four large spiral arms that wrap around it. Spiral galaxies make up about two-third of the galaxies in the universe. [Infographic: Our Milky Way Galaxy: A Traveler's Guide] Unlike a regular spiral, a barred spiral contains a bar across its center region, and has two major arms. The Milky Way also contains two significant minor arms, as well as two smaller spurs.
