Nikola Tesla's most famous attempt to provide everyone in the world with free energy was his World Power System, a method of broadcasting electrical energy without wires, through the ground. His Wardenclyffe Tower, pictured above, was never finished, but his dream of providing energy to all points on the globe is still alive today.
Green Energy 同 Free Energy 係兩個唔同既概念，如果Free Energy成功，電力公司就收唔到你既錢，利益衝突呀。
