I have some ideas in mind how to structure content in a way that is more adequate for skimming. Long texts are simply not really navigable in the finer portions (only in chapters and subchapters), and that makes them unadequate for serving in a workplace for content (snippets of scientific work etc.) and as a storage for content that is indexed in the mind.

Some ideas for structuring:

  • all traditional means: title, headers, sub-headers, paragraph headers
  • Line headers, for summarizing the content of a short paragraph
  • making much greater use of symbols (using street sign symbols as a well-known reference set)
  • foldable paragraphs, like in mindmaps: there is a title, but the content appears only after clicking on the title
  • hypertext
  • paragraphs that appear when hovering over them with the mouse
  • diagram languages
  • using structured language, e.g. for todo lists, inspired by programming languages incl. their choice of indentation
  • formula typesetting

In all that, it is important that this kind of content is producable in real-time, just like long texts.

Two or three days ago, I had an idea what to do to stop the flow of oil from the Deepwater Horizon incident in the Gulf.

Just entered it into the public suggestion form that you can reach via deepwaterhorizonresponse.com: Suggestions. And as sort of a “yes I was (virtually) there” souvenir, here is the idea:

This idea is a modified “top kill” variant to cap the flow of oil from the well: instead of pumping drilling mud etc. from the top down into the well, the idea is to use a long metal tube for that.

The tube, perhaps half the diameter of the well bore, would be inserted from the top into the well. The tube should be as long as technically feasible, even up to several hundred meters if possible. If necessary it should consist of multiple pieces that are connected to each other before insertion.

The advantage of this technique, if feasible, would be that it is more like what will be done via the relief well drilling (intercepting the well bore at some depth). In contrast to the “top kill” method, the drilling mud would hopefully accumulate in the well bore more easily, as it can be inserted without pushing against the flow of a gushing well. Means the chances that this works could be better than with a top kill. The advantage over relief well drilling is, it can be deployed immediately, not needing several month of preparation.

Note that, if this method successfully seals the well, it should also successfully have sealed the insertion tube, as that tube will be full of cement also. The tube can be left in the wellbore therefore.

And here is the “proof” that I was there: 😀

Remember my futuristic, utopian blog post about the sovereign community concept just some days ago? Now just yesterday I found out there is one approach for such a high-tech enabled power community underway. I was seriously bedazzled. May I introduce: Factor e. It took me the whole night (literally) to read and watch all the interesting stuff on their website.

Here is the most interesting stuff that I found on the web about them:

The challenge: finances. It is easy to imagine that a not-yet-autarkic community that in addition to autarky first of all needs to acquire autarky by creating the toolbox for it, needs more money than it has itself. While autarky brings independence from money, this is not the case on the road to autarky … . So if you like what they do and share their vision, you can surf over to their “True Fans” page and from there, join their “1000 True Fans – 1000 Global Villages” campaign and join by contributing a monthly USD 10 for two years. If we want to enjoy an open-sourced equipment for autarkic living, we somehow need to make that happen first …

Browsing the Internet, I had an idea.

There are currently prototypes of “3D printers for printing houses“. As an extension to this, and especially interesting for the developing world: how about a robot that can autonomously dig a house underground, consuming just water and electricity and needing nothing in addition to build the full house? It would be able to create no-cost housing anywhere.

Here is how:

The digbot / underground 3D mill will use a water jet cutter for cutting the soil, maybe photovoltaics for electric energy, and be totally autonomous, controlled by a CAD drawing. It will harvest stones from the cutting area, cut them with the water jet also, and use them to build the walls and ceiling (employing a vault for stability). It should be a self-moving tracked vehicle. It should also be able to carry the cut-off material to the outside itself, or this should be delegated to another self-moving tracked robot.

The underground facilities produced that way can be living space in developmnet countries; in many parts of Africa, no inner anti-groundwater equipment is necessary, as the groundwater level is below 30m; else, a waterproof full inner plastic sealing, insulation and pump is the simplest form. The bot also should be able to create its own abrasive for water jet cutting from hard stones it finds, and to create sand etc. from the stones for mixing concrete, and to apply the concrete for connecting stones (only if necessary) and for creating some. It is no problem if the bots operate quite slow, as it is an unattended, unmanned build process.

The first step to realize this invention would be a tunnel-cutting robot, which can be a shield-shaped one using sprayed concrete and transporting the cut-off stuff on a band conveyor, and receiving concrete, abrasive, electricity etc. likewise in tubes.

Oh, by the way: here are some prices for used water jet cutters.

People’s all-time favorite spare time activity is socializing; either in reality (bars and clubs and homes) or in virtual reality (Facebook, MySpace, …). Now many nerds and geeks, like me, have a problem with that: it’s idle, nonsense activity, just about joking and being cool (if not drinking), but without any substance. It’s non-creative.

Here’s the solution: the hackerspace. By definition, a hackerspace is a common facility for all sorts of hacking, something like a third place (the Ray Oldenburg term) for hackers.

But what caught me is the “feel” of it. It’s very close to that of my imagined power community.

The image above is from a stylish Radar nineteen video about MakerBot. Remember, it’s the Open Source 3D printer I blogged about before. Now the about text of that video tells us that “Makerbot came out of NYC Resistor, a hackers collective offering shared knowledge and camaraderie.” Now what is that? And when watching the video linked above, catch the feeling of the hackerspace: nerd-friendly atmosphere, plenty of resources and intelligent people, freedom to create anything you want. Be sure to also watch this video of a Norway fab lab, with the same spirit but even longer. Wow! I am deeply impressed that this world hosts something like a geek community. I marvel at it and I’m happy that this world hosts more than just the scarcity that I experience currently. And even … this stuff is so close to my own community ideals for the “power community” 😉

(Note: This image is a screenshot of a super stylish video about the MakerBot, and is permissible as a small image quotation under Fair Use of Copyright; since MakerBot Industries is based in New York City.)

And it gets even better:

  • Wikipedia gives us a lot of background information on the hackerspace.
  • Wikipedia article on NYC Resistor.
  • There is hackerspaces.org, a global website about hackerspaces, including a global list.
  • And according to that list, there are even some hackerspaces next to where I live and want to live.
  • And there’s a blueprint: Jens Ohlig: Building a Hacker Space.
  • They are reported to offer a broad sense of community, also internationally: when you are a member of a hacker space, you are a member of the worldwide hacker space, wherever you go.
  • There is MAKE magazine, a DIY lecture for hackers (but not overly cool or challenging).
  • There is a market for geeks to sell stuff they make: makermarket.com. And of course to buy other’s. Not yet that cool items on it, but this might develop.
  • Yea, and there are women in hackerspaces! Saw some in the video. That’s an essential ingredient of social hacking 🙂

To conclude, a collection of the best video clips on hackerspaces that I found:

As many hackerspaces use CNC lathes, 3D printers, lasercutters and the like: it seems that a Fab Lab and a hackerspace are largely overlapping concepts! Where hackerspace defines more the social / community side of the thing, and fab lab the technical side (the methods how hackers can make anything they want).

The Internet contains a subculture for everything imaginable. Here is the Fabber subculture. This is especially cool that such a thing exists, as I envisioned something in that direction, esp. also for EarthOS. Here it is: the culture of creating your products yourself.

They have, so far:

  • the public inventory list for the “official” MIT fab lab specification
  • the FabCentral tools list for fab labs
  • the Makerbot, a fully open source plastic 3D printer to build yourself, backed by a company
  • the Bits from Bytes RepMan V3.1, an affordable, high-quality 3D printer for building yourself (based on RepRap Darwin principles)
  • the Bits from Bytes BFB 3000, the first fully assembled 3D printer for under  GBP 2000 (based on RepRap Darwin principles, but improved, and seemingly not that “open” as Makerbot / RepRap Mendel etc.)
  • the RepRap project, aiming at creating a self-replicating 3D printer machine, can also be built at home
  • the Fab@Home project, also an open source 3D printing (and also robocasting) project; currently, mainly printing with silicone, either direct objects from that or molds for filling in Epoxy
  • the Machines that Make project from the MIT Center for Bits and Atoms; I especially like the “fab in a box” project, which is close to the fab lab concept I have in mind
  • upcoming lower-cost commerical 3D printers, like the HP Designjet 3D printer for 13,000 EUR
  • the Thingiverse, which is like the Fabber’s SourceForge, containing downloadable data for products to mill, lathe or 3D print, tool descriptions, supplier registration for products etc.; one can already find hundreds of geometry files to download to make ones own products. Nice examples:
  • open source 3D modeling software like Art of Illusion
  • the Mobile fab lab, kind of what I want for my A-2 equipment
  • a first fab lab in Germany, open to everybody
  • FabAcademy, something like the online university for digital fabrication (as of 2010-04, they offer self-accredited certificates and diplomas, but no officially accredited Bachelor or Master yet)
  • YouTube videos on the fab lab
  • MIT index of more material on the fab lab

Some background knowledge from Wikipedia:

Ok, and what do I want to do with this stuff when I have my own fab lab? Research, how to use it. What to do with it. Make my own things. Design my Equipment System so that many things of it can be made in the fab lab. And: check if development countries can profit from fab labs. There, transportation and logistics is a big problem, so making all the parts instantly in place when demanded would be a solution. I imagine a hackerspace in Africa where people help themselves to build everything up. Inspirations:

The printed plastic parts can even be re-used to make new ones. This would be about adding the intelligence of a fab lab to local materials, to create wealth out of nothing, in an autarchic community. It would include working with stone in a 3 axis CNC mill, or even on a CNC angle grinder for cutting stone. I currently have a draft for such a machine in my TEQ4 Equipment System notes, which can create CNC-cut, LEGO brick style stones to build houses and many other structures from. Very durable stuff, made from cost-free material that just lies around!

Something happened today that has not happened for a long, long time since I know the Internet. I was seriously bedazzled. Totally speechless. I read through complex scientific texts for hours, understanding less than half, and still wondered if all this is just a big fat joke.

Fact is, I found a blog of a guy who claims to have done nuclear fusion at his home … a star in a jar, including a 200 million degree plasma. And now he attempts to build a fusion reactor, at home. And there are several other hobbyists, approx. 24 worlwide [source], who also achieved nuclear fusion at home. I have read about home-made electron microscopes etc., and that would not be stunning to me any more … but nuclear fusion? This is so awfully crazy … hope he succeeds with the reactor 🙂
