Need to make the power modular to start. Super micro uninterruptible power supplies for essential infrastructure. Alpha and Beta Voltaics paired with a variety of other energy storage and generation methods can create uninterruptible power supplies that can isolate from each other on a circuit board level up to large battery arrays paired with solar and eventually nuclear and even chemical fuel cells or turbines from Sabatier reaction methane. I'm super optimistic for gasification for waste stream recycling and chemical manufacturing for 3D printing too. Flash graphene has huge potential. Microgravity may have advanced applications for graphene manufacturing for quantum computers and advanced solar cells with excellent durability and thermal resiliency. Habitats should incorporate permaculture principles to paraterraform in orbit with simulated gravity or in a domed Crater. Ecosystem architecture has huge potential for Earth applications to mitigate local effects of climate change and reverse desertification. The natural symbiotic economy within ecosystems is very efficient and can supply another circular economy with hydrocarbons for polymers and fuel with biomass and atmosphere

I've been very encouraged by the development of alpha and beta voltaics. Small continuous power supplies can be installed on circuit boards to give them some amount of uninterruptible power supplies. A single alpha/beta voltaic cell inside a larger lithium or sodium ion battery could allow it to trickle charge such that it can be restored from zero charge if it is left in a power saving mode. I think combination hybrid power systems offer the most resiliency capabilities over time. 3 or 4 separate power supplies/storage combined to make a robust microgrid in space could overcome the long lunar nights and missions to deep space

This institute has not the slightest idea. Neither about physics nor about gravity. If they really want to be useful, they should not be thinking about gravity but about inertia. Because that's where the crux of the matter lies. You have gravity between masses as well as artificially generated gravity. You can conceal the effects of gravity with suitable arrangements. The effect of inertia, however, controls you mercilessly, without you having any chance of circumventing it with any trick. This is the curse that we humans cannot get under control with any technology. It will prevent us from being able to operate outside of our narrow solar system.

This was a great presentation. I'm most optimistic for long term development of space infrastructure to tap the abundance of energy and resources to Off-World toxic industries like electronics/chips factories. Space stations to support Mars colonization with Hilton level luxury hotel rooms that could simulated Earth gravity in orbit of Mars would catalyze the development of asteroid mining for sure. Artificial gravity may be useful for metal refining as well to separate molten metals. Ultimately large factories in space give Earth incredible resiliency. I do wonder about the impact of increased traffic in and out of Earth's orbit. What is the impact of reentry on upper atmospheric composition? If we develop the capacity for large scale manufacturing in space, what is the best method to return mass to Earth?

I think a space port may be a bit more attractive term than a space town. It would be great to work on establishing international standards for hatches to be compatible. A rotating high tension cable with truss lattice connecting a Ferris wheel style port for simulated gravity and connection points at the center axis for microgravity experiments.

How about two vehicles that are connected when accelerating. And, once they coast, they have a means to winch apart with a cable. Such that if they start by rotating, they could winch apart some rather great distance because it is merely a cable that connects them, allowing the final distance between being so grand that it allows for a very slow rotation and hopefully reduces Coriolis sensations? A cable seem reliable, effective, inexpensive, allows for a quick means to winch apart or back together, and might allow for huge diameters. And, as I say, if a planned acceleration is due to happen soon, winch back together. Balance between these two vehicles is important I suppose.

I'm most optimistic for the near term use case for a Mars life support habitat. It seems likely that the costs associated would propel everyone to just endure microgravity or lunar gravity near Earth. Mars may require a permanent orbital life support habitat for people to live in perfect comfort in orbit while doing periodic surface missions while building the base on the surface. In my opinion long term we will a unirail circular train of life support habitats on the surface to recreate 1G in between doing time in the native Martian environment on the surface. Once the Mars habitation gets started it will compel the space industry to support the settlement and develop the capacity for large O'Neal Cylinders that I'm most optimistic for long term offsetting land use to allow for the Earth to return to preindustrial conditions. It seems to me that lunar development will be more beneficial for humanity but Mars settlement will rapidly force people to devlop artificial gravity. Lunar development may not require people in space at all. China is going straight to robotics which may give them all the advantages of resource exploitation without the costs of life support infrastructure. Im most optimistic for the space industry to redefine itself as a solution to climate change. I argue that carbon and other greenhouse gas removal can be integrated into the space industry through carbon neutral rocket fuel like from Terraform Industries. Other advanced carbon based materials like graphene and graphite can be developed and advanced chemical manufacturing can be developed for a space economy based on 3D printing polymers. Advancing this tech for space will advance it on Earth as well to replace the petrochemical industry and accelerate the circular economy of near perfect recycling with plasma gasifiers and flash joule heating. Biodynamic regenerative agriculture systems can be developed in orbital facilities with biochar charged with microbial and mycological soil amendments from Earth to innoculate regolith or orbital terrariums. I think humans in space is romantic and compelling and ultimately necessary to motivate the difficult task of "domesticating" space, but we have more to gain through focusing on lunar and asteroid harvesting than Mars. Nonetheless, going to Mars will make all of the rest inevitable. We may try and fail to commercialize space for money, but if we settle Mars for the advancement of the spirit of exploration in the name of the light of consciousness itself, then our path to restoring Earth to Preindustrial conditions with the unlimited resources and energy of the solar system is almost inevitable. So we need artificial gravity to settle Mars in my opinion for an orbital life support habitat.

Send up 3 or more starships and connect them with a latice of high tension cables and trusses. Spin it and test in Cislunar space. Then send it to orbit Mars to serve as a life support habitat for Martian expidetions so they can go up and down with a convienient source of 1G and full amenities as the Martian base is developed. Should have a fuel depot in orbit and 2 redundant return crafts for emergency evacuation.

In terms of Newtonian Mechanics it may be appropriate to call this "artificial" gravity, but in terms of General Relativity it is a simple consequence of the entire mass of the Universe rotating around the space habitat. It is therefore natural, not artificial.

Wasn't this established long ago ? 250m radius rotating at 1.9 rpm. Approximately 1g and low enough rotation to avoid vestibular problems. I remember a 3 spoke design that had a habitat at the end of each spoke and elevators inside the spokes and all the transfer systems in place and even fully pressurised from fixed spine to the rotating elements.

This "fraught" (h/t Courtney) but vital conversation provides a roadmap for respectful dialog leading to compromise and accommodation. This framework could be applicable to a host of questions that will need to be answered if we're to be truly successful Beyond Earth.

artemis is over. nasa threw away 3billion dollars on a landing system that's never going to happen. spacex is going to kill it in the space yacht market, though. invest early.

What a great topic. If we accept that Earth has been mistreated by our industry, and if we accept that all interred human remains are sacred...both of which we have now done...we must face the clear historical parallels here. We have begun our colonization of other worlds in much the same manner as usual: forging ahead and planting national flags without thought of our purpose as a species, and leaving trash everywhere we go. Here's our chance to set a new path, but we're already blowing it in our eagerness to get there. Exploration is great: so is conscience. What have we learned? Thanks for having the discussion, it's vital.

Promo*SM 😒

Sounds good. Hopefully some of the sessions of your conference will be webcast or otherwise made available.

A good book on the spin subject is "Mars Close to Home: The Case for a Mars Simulation in Earth Orbit" by Gerald W. Driggers, 2015, 128 pages. The Space Studies Institute has been advocating for a G-Lab since 2012.

Some more points. 1. So glad you all are working this. 2. Government policy: prepare for disappointment. 3. Given ~100kyr human engineering experience in g vs ~0 in microgravity, I wonder if Lunar research centrifuges in the Artemis outgrowth will provide data sooner than orbital facilities. 4. Given the timespan for approval, funding, development, flight article completion, and launch scheduling for an effective variable-g orbital facility, it’s even money Musk will do the experiment first-at least for .38g. But again, thank you and good luck!

Excellent point about asteroid material refining requiring centrifuges. Synergy.

Thanks for a great discussion. Could you please post the 'slide pack' section as a separate piece as it gets a lot across in a more digestible manner. Thanks again

Paragon CEO coping hard. I wouldn't invest in them that's for sure

Other than developing fuel depots another major key that will open up economic growth in cislunar space will be drastically reduced cost to orbit

The video doesn’t appear on the channel. Did you intend for the video to be private?

Very nice presentation. Any chances we can access to Tory Bruno's slides? Thanks

I'm like 99% sure Tom is just Steve wearing a fake beard

Awesome presentation and awesome mustache!
