We use about 1/8th as much silicon to make a watt of solar panels as we did 20 years ago. Consequently, energy payback is about 5x faster. (there are energy costs other than silicon) Modern panels use so little energy to manufacture that they could be in the shade most of their

First principles building design is absolutely critical for scaling human civilization. Bad design isn't just killing us on energy costs - it's literally killing us. The risks increase non-linearly as population grows. Airborne illness is transmitted through air as waterborne

The Road to Making Life Multiplanetary: an update from Elon Musk on SpaceX's plan to reach Mars

Jared Isaacman should fly the first Starship mission to the Moon and take Chun with him. US gets back to the Moon and brings the first Chinese astronaut. Cooperation not competition.

We’ve entered the next phase of our flight test program, showcasing piloted Midnight flight, as well as CTOL capabilities. The piloted flight featured a conventional take-off and landing (CTOL) demonstrating the robustness of Midnight’s landing gear which is capable of

Haven-1: The Mission Ahead. Our incredible team at Vast is hard at work turning this trailer into reality next year!

If ever SpaceX needed some love, it's now and I'm ready to give it to them. When I was sick, I got an amazing card from Elon Musk signed by dozens of his hard-working employees, not to mention tons of swag. I love you, SpaceX. You are a great American company that has risked

youtube shorts is the most dangerous brain rot platform with tiktok you know what you’re getting yourself into the second you click the app But shorts shares the same app as youtube so it’s, very easy to want to watch an educational video and get “accidentally” black holed by

This is the only public notice I've seen to date of an RS-25 engine test that took place Friday. According to a source, this particular engine is designated for the Artemis V mission. So NASA is testing engines for missions that the White House has sought to cancel.

NEWS: Redwood Materials, founded by Tesla co-founder and current board member JB Straubel, has introduced Redwood Energy. Redwood Energy's first project will be the largest solar-powered, off-grid data center in North America, and the world’s largest second life (recycled)

"I predict that by 2042 95% of humanity's energy usage will be downstream of solar." — Casey Handmer Casey Handmer

And they would even more if we had cost reflective pricing! We’ve told people for years to turn off their AC when they’re not home to “save energy,” so everybody comes back home at the same time, and everybody’s air conditioners turn on at the same time. Instead, we should be

U.S. Department of Energy Secretary Chris Wright Are we just going to ignore the fact that China can build an entire U.S. nuclear fleet worth of solar generation every year? That sunlight is >99.9% of Earth’s energy budget? That by 2030, China will be able to build an *entire U.S.* worth of generation from solar and storage

Approx SpaceX Raptor engine startup sequence. Timescale not representative

At $51/kWh, you can store 100% of the daily production of a ~$1,000 solar array for just ~$300. You can dispatch that for any demand profile you want. Flat, peaking at night, all over 4 hours — whatever you want. For most things and most grids, demand not only exists during

In reality, the bill says nothing about NASA's science missions that are gutted by the President's Budget Request. So we are abandoning real, existing assets in space to spend billions on missions a decade from now that may very well not fly.

New video in 20 minutes! What do you think? How much performance increase would a Starship yeet produce, how much energy would be required? 🤔 Get ready for one of the most numbers heavy but fun videos I've ever made!

NEW VIDEO!!! "Could We Help Push Rockets To Orbit?" a deep dive on the math, the physics, the potentials and problems of launch assist systems including catapults, maglevs and vacuum tubes. This is a very fun video to watch! Enjoy!!!
