EXCERPT: With electricity cost going up and the likes of British Gas hiking up their price, everyone could use a bit of free energy. There are a number of ways to harvest renewable energy including solar and wind, however, the cost of setting up a wind farm can be quite high. [Mr Tickles] has uploaded a video where he has a cheaper DIY method of making a DIY wind turbine. His project uses a commercial ceiling fan as a turbine for converting the wind energy into electricity. PVC pipes are used to mount the entire thing such that it becomes portable. A cardboard fin is used to make the propeller face the wind but there are plans to upgrade it in the future.

He accomplishes this using a rig he put together for only a few hundred dollars. The heart of the system is a Sun Joe pressure washer that he bought for $150 on Amazon. A commercial waterjet cutter costs tens of thousands of dollars. Even a super-low-end cutter, like the Wazer, crowdfunded on Kickstarter a few years ago, sells for $6,0000. Ben’s cobbled-together rig might not look like much, but it does get the job done. In the video, you see him....
