Which means that they have nothing to compete on other than patriotism when Chinese companies do the same for less. For example, I believe ... 06:30 < kanzure> ... MakerBot changed their extruder design for one that was suspciously similar to something one of the Chinese manufacturers came up with. Then their parent company Stratasys sued that company to stop them selling their printers, claiming the extruder infringed a patent of theirs via some, errm, creative interpretation of the patent claims. Buying MakerBot printers doesn't even help fund the companies that do the original R&D - it helps ... 06:30 < kanzure> ... fund someone that's trying to sue them out of business.

I agree with you, there are several factors at play in what happened to MakerBot. I believe Bre learned the wrong lesson -- going closed might have looked like the obvious solution to their drop in sales.

Not sure how the landscaping fares while this expansion is happening. ... 18:59 < kanzure> ... I’ve noticed that after the heyday of High Frontier, there’s been a lot of focus on incremental expansion with continuous occupancy. Peter Kokh designed helical structures with this in mind, and I’ve seen a banded tori design with a primary mirror which constantly grows in area as new tori are added. I had never thought lack of incremental expansion in the 70’s designs was much of a problem. When things get crowded, you ... 18:59 < kanzure> ... build a second habitat, and about half your population immigrates. Repeat as needed. But lots of people seem to see a need for continuous expansion of the original structure, and this seems another example. I’ll have to admit, building a newer, much bigger pressure hull inside the smaller existing one is quite a trick. They claim this technology could support the same land area as a Stanford Torus with only 6% the mass of the ... 18:59 < kanzure> ... aluminum hull of that design. Ultimate scale: 16 km diameter torus (there’s a gorgeous piece of artwork illustrating that). They seem to agree with the more-recent assertions that the Summer Study underestimated shielding mass requirements. Water bags are used in the separate (and only very slowly rotating) radiation shield. The light-pathways seems rather complex. I think this is a consequence of their assertion that the chevron ... 18:59 < kanzure> ... shields would be inadequate. (They cite only 1 inch thickness of aluminum; I thought I remembered there being at least a few feet of shielding thickness in there, but it’s been a while since I read that study.) But I seem to remember telling somebody that we should not concern ourselves with the arduous travails of the photons, so I guess that’s not a valid objection. Their objection to the mirrors of Island 3 concern the ... 18:59 < kanzure> ... energy requirements of moving mirrors under multiple G loads.
