A gallon of water is all it takes to keep a tent cool inside

A new fabric developed by researchers at the University of Connecticut has the potential to reduce the temperature inside a tent by as much as 20 degrees Fahrenheit. Tent fabrics today are designed to keep people inside dry and comfortable by blocking out water and wind. However, they tend to work in the opposite direction, keeping hot air inside the tent from getting out.  Even with ample ventilation, the inside of a tent can feel oppressive on a hot summer day. That's great when temperatures drop in the evening. To lower the temperature inside your tent, you can always bring a portable air conditioner, but these require one ingredient, which is often scarce at rural campsites: electricity.  You don't want to have to carry a backpack full of batteries, and a solar panel simply won't be able to generate enough power to run a portable air conditioner or even a simple fan for an indefinite period of time. tent | Unsplash Al Kasani, a researcher at the Center for Clean Energy Engineering at the University of Connecticut, developed a fabric for a tent that self-cools. He was inspired by the concept that "plants wick water from the ground and then sweat to cool themselves."  The fabric has been enhanced with titanium nanoparticles that draw water from reservoirs at the base of a tent and spread it across the fabric's surface, where it evaporates and creates a cooling effect that reduces the temperature inside the tent by up to 20 degrees F. This allows the tent to still be easily packed down. A gallon of water, according to Kasani, can keep a tent cool for up to 24 hours, and the effect can be achieved with water from a stream in a more rural setting or from a faucet at a campsite. In other words, if you don't use clean, purified water, the evaporative cooling won't stop working. The university says that "industry interest in Kasani's technology has been high," and in a few years, if it goes mainstream, it could help make roughing it in high temperatures feel less rough. However, it will be a while before we see this upgraded fabric showing up in camping gear because the material is still in the research phases.
