Staying Warm and Going Green!
In Minnesota, they know how cold it can get, so they’re looking for innovative ways to stay warm. School officials are going deep into the ground to harness geothermal energy, which is then used to create a warmer environment for students.
Got some extra cans sitting around? This PF innovator did, so he made a DIY solar heater. Items that would’ve gone to waste, such as recycled beer cans, are put to good use and become part of a solar home heater!
