Shocking AI prediction from the “Billionaire Whisperer" (Ad)

Marc Chaikin's Power Gauge system flagged Micron before it soared 970 percent, Celestica before a 6,600 percent run, and Nvidia before it climbed more than 50,000 percent. Now Chaikin says a new AI data center technology using 99 percent less electricity, water, and space could accelerate scientific breakthroughs 360-fold, and one company behind it just flashed bullish in his system.

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
