Dr. Ben, the idea that "making materials in space" will save "Carbon" or even "energy" is so asinine, it is hard to take you seriously. Before you make a video touting all the "supposed" advantages, don't you feel at all obligated to get some proof that such concepts are based in reality? At least, something to "prove" your claim that sending a rocket into space to make 1 kg of diamond crystal will save "energy" as opposed to simply being "near impossible" because of gravity. Instead of all the "Buzzword" marketing that seems so common these days, why not just call it what it really is... a very expensive process for making very very near perfect crystalline structures that will be sold to the highest bidder. This "could" have been a great video. But instead of focusing on the amazing technology and the benefits of the purity of crystalline products, there's always got to be some ridiculous claim thrown in about saving carbon and energy, when that has almost nothing to do with it. It's about making products with a purity that otherwise couldn't be made on Earth. Until technology allows for sending objects to space at "extremely low cost", we still have to pay for the fuel and rockets to get the materials up there and safely back, which is very very expensive.
Having said all that... when they finally do find a cheap reliable way of sending tons of carbon into space to make diamonds, sure, maybe it will be worth it. But advertising this as a way to do that now (near immediate future), using the current method of sending up rockets, is simply unproven at best, unless you can truly demonstrate the data.

Ben, I love the idea of space manufacturing, and the fact that it has the potential to make it possible to do useful things that simply cannot be done on the Earth's surface. However, the goal of reducing CO2 emissions is crackpottery. The best scientific evidence shows that CO2 emissions are beneficial, not harmful. If you'd like to see the evidence for yourself, you can find my contact info by clicking my picture/handle, then clicking "About."

What is the per kilogram carbon emissions for all launches successful to orbit or not. Is carbon generated as a returning vehicle enters Earth's atmosphere. Reg the unknown mass of a de-orbiting space forge, unmanned, no booster rockets, love to see the MSDS for all materials contained within a free falling mass entering our atmosphere, during initial re-entry vehicle is uncontrollable and mission control will not know if vehicle is plummeting in the general direction needed for the mechanical fins to deploy and should each of these little mechanical fins work correctly, this still supersonic mass is to be pointed, not guided, pointed towards a splashdown area just off the coast of England, actually not England, why well England's West Coast parallels Ireland's East coast with Irish see separating each coastline, the distance coast to coast across the Irish Sea is a short one. It's little better on UK's east coast facing France, Netherlands, Germany and Denmark but with territorial rights and the bad weather and the incredible currents of the North Sea seems problematic. So splashdown would be off coast of Scotland naval traffic, oil rigs, wind farms fishing fleets are issues as is the marine traffic of south coast of Ireland and UK, and should any one of many points of failure do just that, then this returning mass will require onboard explosives to destroy it, ok no explosive onboard during launch, orbit and reentry, good idea, then this out of control mass needs contact with a guided missile, preferably several hundred mile out in Atlantic, because the thought of it impacting a populated area, aircraft, Marine traffic, oil rig etc etc is unconscionable terrifying. Has anyone considered the volume of all traffic and movement around the coast and up to cruising altitude about the British Isles. So even if this space forge returns and is with a few kilometers of ???? Where you thinking of earmarking some area, very difficult to fence off and there's always someone who didn't get the memo or hear the bell. This concept is worthy of humanities attention but keep in mind just as with humanity mistakes have and will continue to happen, pun intended without remorse. If developer's and powers that be with in UK want to launch and return capabilities then let it happen on their own soil. And as mentioned to date technology ability to track small supersonic masses de-orbiting is not a tried, true nor perfected enough to be pointing it at your damn coastline. Best wishes, stay well and always curious. Respect.
