Creepily enough, Wal-Mart is cialis generic australiageneric viagra tablets the largest private user of energy in the world. So they're pretty interested in using less energy, especially when it gets them good publicity at sites like EcoGeek.
Well, they've done it again. At a new store in Las Vegas Wal-Mart has installed advanced, low-energy roof-top fluid coolers. These use the surrounding air to cool water, which is then pumped into pipes below the store's floor. The resulting cooling completely eliminates the united healthcare viagra need for air conditioning and, in Las Vegas, that's a huge amount of a store's energy cost.
One problem though, Las Vegas doesn't really have very much water to spare and, unfortunately, these fluid coolers rely on evaporating away many gallons of hot water to leave the cold water, for cooling, behind.
In hot areas with plenty of water, this seems like it would make a lot of sense. But in Las Vegas, where they're pretty certain that there won't be any water left in ten or twenty years, this might not be the best solution.
