PLANNING AND LEADERSHIP FOR A BETTER WORLD
PLANNING AND LEADERSHIP FOR A BETTER WORLD It has been mighty hot here on the East Coast over the past week, with little letup in sight. So I decided to spend a little time looking around for some smart technologies that promise to keep us all cooler during those oppressive, hot, humid summer days.
1. Cooling the big box. Big box stores have become part of the retail landscape. The problem is those big box stores require massive cooling systems to keep shoppers cool. Enter the University of California at Davis' "Western Cooling Challenge," for systems that are efficient and green. Sciencecentric has a story on the first winner of the UC Davis competition: a Denver-based company called Coolerado that offers big box stores more than 80 percent energy use savings.
2. Solar air conditioning. While a lot of solar technologies are aimed at producing electricity, it may be more sensible to aim at what that converted electricity is being asked to accomplish. In the United States (according to MIT), heating and cooling accounts for 60 percent of building energy use. MIT has undertaken a Solar Air Conditioning Systems (SACS) project that will showcase solar energy as a heating and cooling process.
3. Cooling your data center. Data center design in the past has been a hodgepodge of priorities. With a single focus on uptime, you've ended up with designs that use computer servers inefficiently while generating a roomful of heat. Once you have that roomful of heat, you then have to build air conditioning systems to cool down that wasted heat. Sounds crazy? You bet. Computer virtualization may solve part of the problem. One of the more interesting technologies is the return of liquid cooling to data centers to efficiently cool computer servers and related equipment. One approach is to tie in a building's existing water-cooled infrastructure to the computing infrastructure.
4. A cooler hybrid car. Can hybrid cars and air conditioning ever find common ground? This will be tough, as air conditioning units accelerate the battery charge. Here is a good overview, but I'm guessing there is a lot more work to be done trying to come up with a hybrid or all-electric car that can find a happy co-existence with air conditioning.
5. A cooler you. Is there really a technology on the horizon that will keep you cooler? A Wall Street Journal article may have found the answer with a discussion about the return of shade trees and you sitting on a front porch enjoying a cool drink. Now that may be the best way of all to beat the heat on a hot August afternoon.
