Spaceships: Hulls and Indestructible Coating?!

Used in everything from bullet-proof vests to the walls of the Pentagon, polyurea's strength comes from its long-chain molecules.

The crew and the internal fittings might get squashed in a crash, but the hull will remain in tact.

This is useful, since about a third of my starships look like watermelons.

Well, metaphorically, starships are watermelons.

Starships: Engineering and The Halo Drive

How could we one day travel between the stars with real physics? Perhaps the greatest challenge to interstellar flight is energetics - it takes vast amounts of energy to accelerate even small ships to 20% the speed of light. But what if we could steal that energy from where? Perhaps even a black hole. Enter the "halo drive", a video by Prof David Kipping based on his new peer-reviewed research paper on the subject.

Further reading and resources:

► Breakthrough Starshot homepage: https://breakthroughinitiatives.org/i...

* There’s an error in the video at around 8:30, 2 trillion joules is the cumulative energy output of a typical nuclear power station after 2000 seconds, not 20 days.

Starships: Life Support, Engineering and Bill Gates-Backed Carbon Capture Plant Does The Work Of 40 Million Trees

In Squamish, British Columbia, there’s a company that wants to stop climate change by sucking carbon dioxide out of the atmosphere.

It’s called Carbon Engineering, and it uses a combination of giant fans and complex chemical processes to remove carbon dioxide from the air in a procedure known as Direct Air Capture.

Direct Air Capture isn’t new, but Carbon Engineering says its technology has advanced enough for it to finally make financial sense.

The company is backed by Bill Gates — but also by the oil giants Chevron, BHP, and Occidental. These partnerships will bring Carbon Engineering’s tech to market by using the captured carbon to make synthetic fuels and and help extract more oil from the ground.

Will Carbon Engineering’s technology decrease the amount of CO2 in the air, or is it going to prolong our dependence on fossil fuels?

Trees take up too much volume on a spaceship.

A closed system certainly ensures that all the air gets recirculated to a central fan, the carbon dioxide can be captured and dumped into the main fuel tank.

The newly carbonated hydrogen fuel gives an extra pep to the transitional process, and increases the size of the jump bubble.

Spaceships: Hulls and I Waterproofed Myself With Aerogel!

Aerogel has extraordinary properties but it can be tough to work with. This video looks at modifying aerogels to take advantage of their unique characteristics.

Aerogel’s extraordinary properties are due in large part to its structure. Aerogel is a solid but on the nanoscale it has a mesh or sponge-like structure. The struts of this structure are nanoscale, as are the pores at around 20nm across. This makes silica aerogel incredibly light (it was once the lightest solid but has now been superseded by graphene aerogel), transparent and adsorbent.

An ice-cube sized piece of aerogel has an internal surface area roughly equal to half a football field. Aerogel is used in high end museum cases to regulate humidity. Plus it helps maintain the vacuum on the Mars Insight seismometers - it adsorbs moisture and other outgassed volatiles that come from the spacecraft itself. Proposed uses include as a physical insecticide by ‘drying out insects’ reducing the need for chemical and toxic pesticides.'

Seems the way to go with insulation, and if mass mattered.

Spaceships: Accommodations and Central cube sets Paris micro-flat into work/living/rest modes

To create more functionality in a 16-square-meter (172-square-foot) Paris apartment, designers Elisa Nobile and Enrico Bona created a custom cabinet containing two beds, a desk, a kitchen and a bathroom with an unfolding shower. The furniture cube leaves more than half the space clear so it can be used as a rotating bedroom, dining room or home office: a secondary table descends from an adjacent wall offering space for the owner’s model-making interests.

The designers (EDB Studio) wanted the cube’s multifunctionality to remain hidden so they avoided handles, instead relying on a push/pull system to unfold furniture or open cabinets. To prevent fingerprints on the white cabinets, they used a nano-tech material called Fenix which if scratched can be repaired by applying heat.

A modular solution to easily furnish staterooms.

Probably have to ensure that corridors are large enough to just install as one unit, otherwise it will have to assembled in the stateroom.

Starships: Hulls, Armoured Bulkheads, and The UNSC Pillar of Autumn -- The MOST DETAILED Breakdown (ft. Installation00) | Halo Lore

Today, we partner with Installation00, an excellent Halo Lore channel, to breakdown the PIllar of Autumn - the modified Halcyon Class Heavy Cruiser used to transport Master Chief to Installation 04 in Halo CE.

Like all UNSC Capital Ships, the Pillar of Autumn sported a massive magnetic accelerator cannon, thick titanium armor, but was also augmented with distinct modifications. We'll look at it all on today's Halo Capital Ship lore video.

Spaceships: Hulls and The Mars Homes That NASA Awarded $500k

AI SpaceFactory's "MARSHA" Mars Habitat just won NASA's 3-D Printed Habitat Challenge. Compared to others, their design looks downright luxurious. It has multiple floors, spacious living quarters, and plenty of windows to gaze upon the Martian horizon.

I'm not too sure how this would fare on atmospheric reentry, or possibly exit, but it seems a fast and neat way to get a cheap hull for a spaceship.

Spaceships: Engineering and Beam Powered Spaceships

Sign up with Skillshare for 2 months of Free classes: https://skl.sh/isaacarthur11
In order to get into space, we require either huge amounts of rocket fuel or dangerously powerful energy sources, making personal spacecraft a technology limited to science fiction. But by harnessing beamed power sources to run engines, we may be able to create a spaceplane cheap enough and safe enough that anyone could have one in the future.

https://www.youtube.com/watch?v=Wol8EU6Rtbk



1. I remember first reading about beam powered transports in one of those Amazingesque pulp magazines that I picked up in yard sale; technically, it was a hall, since yard sales there were an alien concept. Power was beamable to at least inner system spacelanes, and possibly to the outer system; I suspect beyond near orbit this doesn't become possible.

2. With laser (ground) based propulsion, it was The Mote In God's Eye, which depending on the economics, probably an option inner system and upto a centiorbit for commercial interstellar vessels.
