How to Build in Space — for Life on Earth | Ariel Ekblaw | TED
Is space the “final frontier” — or the perfect place to revolutionize life on Earth? Space architect Ariel Ekblaw reveals how self-assembling structures could build orbiting real estate in space dedicated to solving humanity’s greatest dilemmas on Earth, leading to scientific and medical breakthroughs only possible in zero gravity. (Recorded at TED2025 on April 11,…

The Controversial Climate Tool Funding Real Change | Sandeep Roy Choudhury | TED
If a company plants trees to offset its pollution, is that climate progress — or is it greenwashing? Critics of carbon markets say it’s the latter. But Sandeep Roy Choudhury, who’s spent two decades financing climate projects from rural cookstoves to coastal forests, says the real failure is discouraging companies from even trying. Hear his…

How to Be a Great Listener | Maegan Stephens, Nicole Lowenbraun | TED
Have you ever left a meeting thinking: everyone talked, but nothing was achieved? Chances are that people were listening to each other, just not in the same way. Listening experts Maegan Stephens and Nicole Lowenbraun unpack the four different ways to listen, sharing a practical framework that could change how you respond, build trust and…

Have you heard of aphantasia? Here’s what it is — and how to know if you have it #TEDTalks
Picture this: a rocket ship crash-lands on a planet, and an alien approaches the spacecraft. What do you see in your mind when you visualize this scene? For Alex Rosenthal (and many others), the answer is: absolutely nothing. Exploring the fascinating science of aphantasia, or the inability to generate mental images, he shows why our…

Why cant this environment be simulated with AI? I think this might be vulnerable to an EMP from a rouge nation, killing everyone onboard as the magnets separate. Something like this would require humanity to actually commit to setting our differences aside and working together. Some type of utopia on earth before we try to create it in space or on other planets. Its like trying to create a tower with a foundation built on sand at the beach, while waves lap at it, we have all done that as children.

All the more with remote-controlled-robotics and super-sustainable food systems (hydroponics + waste-water?) for orbital visitors – those can also have colossal benefits on Earth in the near-future, if done well,
but even more – it is already rock-bottom-easy to make or hire someone (or a team) to help make illustrations, animations, and on into digital / virtual worlds for proposals,
for development, refinement, testing, stress-testing, optimization, peer-review, teaching & training via game-characters + a.i. characters & etc., demonstration, investment / crowdfunding,
I would think Project proposals + game-world development & optimization would be beneficial, all the more with more collaboration amongst teams working in the same directions.

You just have about 100 drones and a hollowed out asteroid with the Bessemer process in it
And the drones have arms to grab, with laser and particle welders, and can plug into a computer
So they just assemble whatever
From a blueprint, when I press “send”
But I use r/c drones to get up to that scale
They’re not self assembling
They get designed, by people, the drones, by people, the software, by people, the original work that the drones move based on

Interesting talk, but where’s the analysis on how much money went into subsidizing these private companies?

Also, what open innovations have these companies contributed that didn’t already originate from NASA?
Concepts around modular space modules and robotic assembly have been around since the 1960s What exactly is new here?

I created a space based solar energy concept in 1984 when I was 14, including a computer graphic simulation on a BBC Micro B machine. It was based on a repurposed SDI or Strategic Defence Initiative programme, also known as Star Wars. A series of interconnected on-orbit solar collectors and down links to earth-based collectors connected to world-wide energy grids. 24 hour solar energy. I’m disappointed that now I’m 55, this concept I came up with as a young teenager has not been made real.

We won’t be able to live normally on earth. We’ll not be humans anymore, unless you build the same gravity artificially. So yeah, I believe, these stations should be used only temporary.
@merion297
June 20, 2025 at 11:15 am
Wow, now that’s what I call an innovative concept! But here’s a thought: maybe this brilliant scientist should first focus on developing (using similar engineering principles) a finely-tunable sunshade that we could deploy in space. That way, we could precisely control the amount of solar energy reaching Earth, slowing down global warming and buying us some time to actually tackle CO2 emissions and get the Earth’s climate back to pre-industrial levels. There’s no point in building self-constructing space stations if we’re all gonna fry here on Earth.

The concept is great, at least as an intermediate technology for human settlement in orbital space and for enterprises requiring no gravity environment.
Futurewise though, when thinking of long term habitats, the problem of gravity must be resolved. This will probably require large structures, that will revolve around their own axis. In such instance this technology will not serve its purpose, as it is not designed to form large toroidal shapes.
But every city starts with building the first house on the first street, so I am holding fingers crossed for this concept.
