Fringe | Season 4 | Episode 8 | “Back To Where You’ve Never Been”
Frustrated by his supposed allies on Earth-3 (?) at every turn, Peter heads over to Earth-4 (?) to try his luck with Walternate. Of course, things turn out to be more complicated than he’d anticipated.
Very little science to write about this week (unless you want to talk about the spectacular battery technology and gizmos used in the Nissan Leaf). The pinwheel-going-against-the-flow-of-air thing wasn’t followed up on, but it is theoretically possible to achieve this effect with a very weak flow of air coupled with radiation (heat or light) as in the Crookes radiometer.
