IBM Solar Collector Magnifies Sun By 2000X – These Could Provide Power To The Entire Planet | Collective-Evolution

A team at IBM recently developed what they call a High Concentration Photo Voltaic Thermal (HCPVT) system that is capable of concentrating the power of 2,000 suns, they are even claiming to be able to concentrate energy safely up to 5,000X, that’s huge. The process of trapping the sunlight produces water that can be used to produce filtered drinkable water, or used for other things like air conditioning etc. Scientists envision that the HCPVT system could provide sustainable energy and fresh water to communities all around the world.

The ScienceDaily article “Greenland’s fastest glacier reaches record speeds” reports:

Jakobshavn Isbræ (Jakobshavn Glacier) is moving ice from the Greenland ice sheet into the ocean at a speed that appears to be the fastest ever recorded. …

This speedup of Jakobshavn Isbræ means that the glacier is adding more and more ice to the ocean, contributing to sea-level rise. “We know that from 2000 to 2010 this glacier alone increased sea level by about 1 mm. With the additional speed it likely will contribute a bit more than this over the next decade,” explains [Ian] Joughin.

Jakobshavn Isbræ, which is widely believed to be the glacier that produced the large iceberg that sank the Titanic in 1912, drains the Greenland ice sheet into a deep ocean fjord on the coast of the island. At its calving front, where the glacier effectively ends as it breaks off into icebergs, some of the ice melts while the rest is pushed out, floating into the ocean. Both of these processes contribute about the same amount to sea-level rise from Greenland.
