🤐 SPOILER ALERT 🤐

Miles Bron is many things: a tech billionaire, a budding guitar player, a possible murderer. As played by Edward Norton in Rian Johnson’s new whodunit Glass Onion: A Knives Out Mystery, Bron is a sheep in wolf’s clothing — a man who’s grown so wealthy and powerful that people forget just how ahead of the curve he may actually be beneath what Daniel Craig’s Benoit Blanc calls his “minefield of malapropisms and factual errors.” 

One of Bron’s biggest tech gambits is a new form of solid hydrogen fuel made of abundant seawater called Klear, which he’s using to power his entire island villa. The fuel in the movie isn’t quite ready for prime time. But hey, even a broken hourly dong is right twice a day, right? Hydrogen fuel very well could be one of the ways of the future (as long as it’s being supervised by people a little less impulsive than Miles). 

What Miles gets right about hydrogen fuel is its flexibility: It can be used to create heat or electricity with no carbon emissions using a fuel cell or special combustion engine. There’s also a clear path to true sustainability by creating hydrogen fuel by using other green energy, like wind and solar.

For now, however, hydrogen fuel is limited to places with plenty of resources, as it isn’t yet cost-effective. In other words, Miles’ villa is the perfect spot for it — that is, if he didn’t cut corners with safety. In reality, hydrogen gas undergoes thorough safety testing, and some car manufacturers in the US and Japan have been safely using hydrogen fuel cells in their private cars since 2014 without incident. In other words, fear not: The Mona Lisa should be perfectly safe for future generations to enjoy.

Hydrogen fuel will next be used in larger forms of transportation, like public buses, aircraft and cargo boats. Who knows? Maybe it’ll even be in the yacht that shuttles you to your next private island murder mystery party.

Glass Onion: A Knives Out Mystery is streaming now.

Some Netflix sets are already using hydrogen backup generators.
