One word of wisdom about water slides. I used to ride “Der Stuka” at Wet ‘n Wild in Orlando (which is “only” 23 m tall) back when I was stationed on the USS Disney World there. The collective wisdom was that you needed to clench while sliding lest the ride turn into “Das Enema” . ‘Nuff said.
Expanciate! Potential to kinetic, I don’t get it.
Converting elevation (the height of the water slide) to kinetic energy (the slider in motion) pursuant to the First Law of Thermodynamics (conservation of energy). Converting the potential energy in turbine exhaust steam to work turning a generator is explained here: http://www.freepatentsonline.com/7987677.pdf Converting computer chip waste heat to power is explained here: http://www.freepatentsonline.com/7980078.pdf
