I appreciate the suggestion because it recognizes the need for a change and that humor is often the best method for making a point. Let me go out on a limb here and just...um...how about, uh, they just come up with a whole new approach? Yes - that's it! Break the mold, march to the beat of their own drum and all that creativity stuff. One could come up with quite a compelling show just focusing on alternative engergy sources. Fuel cells for home power and cars, hybrid cars, flywheels, and what can be done to conserve energy like inflating tires, insulating homes, making cars lighter weight, LED light bulbs, etc. They key, of course, is coming up with a compelling story and core attraction. For example, you could do a Mummy type coaster where the ride has a truly corny theme on energy (song, dancers, everything that makes it cliche) right up to the point where a power outage occurs, and the ride becomes a nightmare (think sudden stop, total darkness, and whistling/steam release like the end of Journey) demonstrating everything that can go wrong when the power goes out (no brakes, no aritifical intelligence control, etc.) culminating in your ending the ride thinking you've just climbed a lift hill and are about to drop when your harness opens...when the lights come on at the exit.
Ok...too much thought for this forum, but the idea is let's go with new and not recycle. It may not be great, but five minutes of thought can lead to a whole mess of ideas!
