How the Moon Could Quickly Become a Boomtown
Mining the moon for natural resources is inevitable, says engineering professor Dr. Leonhard Bernold. He has created a system that avoids potentially crippling efficiency problems.
What's the Latest Development?
When it comes to mining the moon for precious resources, the question is "when", not "if", says Dr. Leonhard Bernold, an engineering professor at the University of New South Wales. We know the lunar surface contains abundant amounts of so-called rare Earth metals like Yttrium, Lanthanum and Samarium, which are essential to building high-tech products of both civilian and military application. The Moon also contains stores of Helium-3, a non-radioactive nuclear fusion fuel that some believe is the way to meet terrestrial demand for clean energy in the future.
What's the Big Idea?
Bernold reminds all the futurists out there that significant technical obstacles remain because mining on Earth is completely different from mining on the Moon. Because there is less lunar gravity, machines would require six-times their Earth mass to gain traction in the lunar soil or keep from toppling over. That means vastly more expensive launches. Lunar dust, which could jam machine gears and clog vents, also proses major problems. Bernold is working on a solution he calls "suction extraction with pneumatic transportation." The technique is especially attractive because it relies heavily on resources, such as solar energy, already on the moon.

Is it "perverseness," the "death drive," or something else?
A growing body of research shows promising signs that the keto diet might be able to improve mental health.
- The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
- Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
- Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
It's up to us humans to re-humanize our world. An economy that prioritizes growth and profits over humanity has led to digital platforms that "strip the topsoil" of human behavior, whole industries, and the planet, giving less and less back. And only we can save us.
- It's an all-hands-on-deck moment in the arc of civilization.
- Everyone has a choice: Do you want to try to earn enough money to insulate yourself from the world you're creating— or do you want to make the world a place you don't have to insulate yourself from?
