Earth's biggest energy source: near Grand Canyon (Ad)

The largest energy source on Earth contains 50,000 times every oil and gas reserve on the planet combined - and much of it sits beneath the desert near the Grand Canyon. A drilling crew just hit the DOE's 2035 targets twelve years early, with costs down 50% in 18 months. Google signed on, Gates invested, and the Pentagon made it a priority. One company has been quietly building this infrastructure for sixty years.tc pixel

It’s not about Greenland (Ad)

The petrodollar arrangement that anchored the US dollar for 50 years quietly expired in June 2024. Since then, China has cut its Treasury holdings by 45% from their peak, and BRICS nations offloaded $47 billion of American debt in a single month. The Trump administration has responded with a $12 billion critical minerals stockpile called Project Vault, equity stakes in miners like MP Materials and Lithium Americas, and a push to secure resources from Greenland to Ukraine. Porter Stansberry lays out the full story in a new documentary, including five companies positioned at the chokepoints of what he calls Trump's New Dollar.tc pixel
