Buy From Amazon.com






Tripp Lite SRCOOL12K Portable Cooling / Air Conditioner Stand Alone Spot Air Cooler 120V, 60Hz, 12K BTU Feature


  • 12,000 BTU of cooling power can cool a 500 square foot room
  • Uses R410a refrigerant (Contains no ozone depleting R22 refrigerant which has been banned by the U.S. EPA in new equipment after January 1, 2010)
  • No water collection tank required. A built-in evaporator expels condensate into the exhaust air stream meaning no drain tube, drain pan or water collection tank that needs to be emptied every few hours
  • Cold air output can be precisely directed through a 71" flexible tube to the 'hot spot' for better, faster cooling. (Standard louvered insert is also included for general room cooling)
  • Auto-restart feature retains all system settings and returns the unit back to its last operational state after AC power is restored
  • Compact and portable - ideal for wiring closets and other space-critical locations
  • Compact, portable, self-contained design; ideal for IT, industrial, commercial and similar applications
  • Features top-mounted control panel with LCD temperature readout and LEDs
  • Provides supplemental, emergency and off-hour cooling in IT and other applications
  • Quick and easy installation. Plugs into a standard 5-15R outlet; no adapter required
  • Requires no floor drain or water collection tank and offers 12,000 BTU of cooling power
  • Standard louvered vent for general room cooling and ducted vent to direct cold air where needed
  • Window/drop ceiling installation kit is included for extracting heat



Tripp Lite's SRCOOL12K is a next-generation air conditioner designed for supplemental area cooling, emergency cooling and off-hour cooling applications. The SRCOOL12K uses R410a refrigerant, which complies with EPA standards. The SRCOOL12K has a built-in evaporator that expels the condensed water through the exhaust duct, so there is no need for a drain tube, drain pan or water collection tank. The SRCOOL12K not only adjusts ambient room temperatures, but can also dehumidify and filter the air, providing better air quality with minimal noise and power consumption. Both a standard louvered vent (for general room cooling) and a directional ducted cooling vent (to direct cold air where most needed) are provided. A directional exhaust duct safely removes hot air from the room. A built-in timer enables the unit to be programmed for unattended start-up and shutdown. An included window/drop ceiling kit provides multiple installation options.

The Battery: How Portable Power Sparked a Technological Revolution

The Battery: How Portable Power Sparked a Technological Revolution Review






Buy From Amazon.com







In the tradition of Mark Kurlansky's Cod and David Bodanis's E=MC2, The Battery is the first popular history of the technology that harnessed electricity and powered the greatest scientific and technological advances of our time.

What began as a long-running dispute in biology, involving a dead frog's twitching leg, a scalpel, and a metal plate, would become an invention that transformed the history of the world: the battery. From Alessandro Volta's first copper-and-zinc model in 1800 to twenty-first-century technological breakthroughs, science journalist Henry Schlesinger traces the history of this essential power source and demonstrates its impact on our lives.

Volta's first battery not only settled the frog's leg question, it also unleashed a field of scientific research that led to the discovery of new elements and new inventions, from Samuel Morse's telegraph to Alexander Graham Bell's telephone to Thomas Edison's incandescent lightbulb. And recent advances like nanotechnology are poised to create a new generation of paradigm-shifting energy sources.

Schlesinger introduces the charlatans and geniuses, paupers and magnates, attracted to the power of the battery, including Michael Faraday, Guglielmo Marconi, Gaylord Wilshire, and Hugo Gernsback, the publisher and would-be inventor who coined the term "science fiction." A kaleidoscopic tour of an ingenious invention that helped usher in the modern world, The Battery is as entertaining as it is enlightening.
