Dave Jones of EEVblog debunks the Solar Roadways project, which raised millions through Indiegogo and government funding. He works through the solar generation and LED power calculations to show the idea isn't viable.
Why Hacker News points people here: HN cites it as the go-to debunking whenever solar roads come up, because it does the math.

“Scientific analysis has predictive power.”
How does it increase our knowledge, or ability to do new exciting things, or our ability to "push the envelope"? It keeps resources from being wasted that would otherwise actually contribute to our ability to "push the envelope." It doesn't. It's a waste of time and effort.
