I'm told it's because the new one is 75% more energy efficient. But...it's...solar...powered. Why do I care how energy efficient it is as long as it stays off the grid? Doesn't greenness then move to the cost of manufacturing a new ferris wheel, not to mention shipping the old one? Or the chemicals used in manufacturing the 160,000 LEDs used in the new wheel?
My brain is on fire. Can not compute.
