That cost comes out of the fuel needed to heat and cool tents on the front lines. However, the trucks that transport this fuel have become targets for IEDs used by the insurgency in Iraq and Afghanistan. According to Anderson, at least 1000 soldiers have been killed moving fuel.
Anderson believes that a simple solution would be to instead spray tents with polyurethane foam, kind of like the foam sealant you would use in your own home. In fact, an active $US95 million contract to insulate tents is producing $US1 billion in cost avoidance, proving it’s both safer and greener than air conditioning the desert. Doing this while also searching for other energy-efficient solutions would save both money and lives.
