Two teenagers from Pennsylvania just solved a problem most engineers ignored. Rohan Kapoor and Jack Reichert created the "Go Green Filter" — a 3D-printed device that attaches to your car's exhaust pipe. It doesn't just reduce emissions. It converts CO2 into oxygen. Using microalgae. The same process plants use — photosynthesis. They built a bio-reactor with water, LED lights, and living algae inside. The algae eat the carbon dioxide from your exhaust... and release clean oxygen back into the air. In testing? It cut emissions by 74%. They didn't wait for funding. Didn't wait for permission.
They 3D-printed the prototype themselves. Now it's being deployed in Indonesia. The cost? Low enough to scale globally. If this works at mass scale, it could reduce billions of tons of carbon annually. Two high school kids just did what billion-dollar companies haven't.
It’s important that you understand what happened last night.
Last night, Stephen Colbert interviewed Democratic Texas Senate candidate James Talarico, a candidate who, by all accounts, is on track in the polls to flip Texas blue.
In response, Trump’s FCC reportedly threatened CBS if the interview aired.
CBS caved and pulled the segment, citing “financial reasons.”
In modern American history, no president has been more hostile to free speech than Donald Trump.
But censorship always backfires.
Here’s the full segment Trump didn’t want you to see.
How to Become Stevie Cohen
When I was 23, fresh out of a top university in New York, I interviewed at SAC Capital (later Point72). I remember walking onto the trading floor and seeing Stevie Cohen sitting in the middle-no office, no separation, while traders around him pitched ideas all day.
That’s how trading works. And that’s how you should use X. You don’t need to be an expert in every field-Stevie Cohen isn’t. His edge is wisdom and logic: knowing which ideas make sense.
The key is to surround yourself with people who’ve proven excellence in their fields. Ignore generalists talking biotech or tech. Find true experts, listen carefully, do your own work, and decide. That’s how you become your own Stevie Cohen-at home, with very little capital.
Key Points
•Follow experts, not generalists, people with long, proven track records in their field.
•Treat X like a trading desk: ideas flow in, you don’t accept them blindly.
•Your edge is logic and judgment, not expertise in every domain.
•When an idea appears, slow down: research it, stress-test it, see if it makes sense.
•Ignore noise, hype, and hot takes. Signal comes from excellence over time.
