Yasa is developing compact oil-cooled electric axial flux motors without a stator yoke, allowing them to reach record power density. Recently, the announced a 42 kW/kg device: superconducting performance but without even using cobalt or 3D printed parts. autocar.co.uk/car-news/techn…

Since a certain nuclear start-up is talking a lot about synthetic fuels from nuclear, I wanted to take another look at the economics of the whole idea and what it would take to make it make sense. I am basing this all off this paper looking into this idea for carriers. 1/8

The Asteroid Institute's trajectory service was what I used to get the plot of intercept trajectories for Comet I/3 Atlas because other services just gave up.

The Nimitz-class USS Harry Truman transiting the North Sea: youtu.be/5cst2GD3EG0 F/A-18 catapult launches are exciting but so much more goes on daily on this mobile airport.

Early concepts for Hardspace Shipbreaker. I can see how hard it is to depict flames and explosions in microgravity, let alone in vacuum. #space #art by David Perdigon. artstation.com/artwork/D5Y459

The Moon is receding from Earth at 3.8 cm per year. The Earth is drifting away from the Sun at 1.5 cm/year. The Sun is expanding over time too. The perfect alignment that gives us our current eclipses is a unique convergence in time and will be gone in the future.

They seem out of the loop... x.com/ToughSf/status…

Some cool extended footage of the Northrop YB-49 flying wing. The original video only had like two good pixels so tried to resurrect the rest. R.I.P. Ozzy 🤘😎

“The ‘less and less’ attitude has everyone in materials R&D focused on greening the end-of-history tech (steel, cement, plastic, fertilizer) or even moving backwards …. It’s out of touch with the longer contours of history” @salmon_mckay Great piece: orcasciences.com/articles/the-f…

Full mission documentary for the 1982 STS-3 mission, restored: youtu.be/7cR0UsenOcI Shown here are the external tank detaching and payload bay doors opening.

Working away on the first exhibit for our Irish science museum series. We created a rigged 3D model of the Leviathan of Parsonstown in Birr, Ireland. It was the largest telescope on earth for 7 decades and helped us draw the first detailed images of spiral galaxies. This will…

The Lunar War is more than just a depiction of conflict in space, but is also a vision of human expansion off Earth and past the Moon. Watch the latest amazing animation:

The preview of 'Laser Propulsion in Space' has an excellent introduction: books.google.co.uk/books?id=9CfcE… It could offers variable 1000-10,000 Isp and good thrust/watt performance, but its strongest advantage is how the heavy generator and spacecraft can be separated by long distances.

Triple world record for 23,000 tons moved on 800 self-propelled axles: -largest number of axle lines under one load, -heaviest weight moved by SPMT axle lines -heaviest load on wheels transferred onto barges cranebriefing.com/news/new-spmt-…
