Methane from Sun+CO2
Catalytic coated carbon nanotubes use sunlight to convert CO2 directly to Methane: http://www.physorg.com/news155471367.html http://pubs.acs.org/doi/abs/10.1021/nl803258p (subscription link). This new process produces conversion rates 20 times higher than previous attempts, and they've shifted the s...

1) Look at your own picture. Imagine a small tangential force on one of the tori, from whatever source. Now add a large axial magnetic force on the same torus. This is a classical buckling problem. The torus will rotate and the four columns will buckle and collapse. ADD the damned diagonals! The li...

You must remove the semi-circular loops because: 1) radial outward forces will break them. 2) they provide an electron loss path. 1) Not if they're not the primary supports and are just acting in a lateral support capacity, as shown in the previous post. 2) This is really the only concern. I'm curi...

Scupperer's idea here will put the semicircular "nubs" into massive bending due to the 60 Tesla magnetic forces you stated earlier, The "nubs" would break from the bending and the whole assembly would fly apart. 60 Tesla, WB-6 was 1.25 Tesla. Am I correct Tom Ligon? Remove all the semicircular loop...

I can't speak to the physics, Scupperer, but I can tell you that getting coolant to those nubs is a hairy business unlikely to succeed. Without coolant, they are useless. If the nubs are capable of providing some support, then the coolant could still be provided from a cantilevered standoff - the s...

http://www.ehlinger.com/scupperer/wb-7x.png Forgive me, I'm just a caveman, and understand very little of what is discussed here, however much I enjoy reading it, but I love geometries. I'm curious what effect reshaping the "nubs" as pictured above might have on the fields. Will changing their inte...

I'm not looking for animation. I'm looking for CAD & 3D engineering modeling. I already know autocad well and a little inventor and I want a legitimate up to date copy. I'm just a little concerned about this particular website. The full version of Autocad has 3-d modeling, and versions from 2000 an...

Thermodynamics is really a limiting analogy for economics; its provides only reductive explanation, and really says nothing about new growth. Personally, I'd go with a self-organizing system to describe it; then one can better explain the positive and negative feedbacks that happen within, as well a...

A guy from VRB Power Systems called me the other day, after I left a request on their web page for more information. Apparently, these people have licensed the technology from the Australian University that developed it, and they hold the license for most of the developed world. After talking with h...

Idiotic. It is the markets that have decided to be where we are today - with no Pollywell and the atmosphere and the seas accelerating towards catastrophe and mountains of radioactive material buried under the floorboards. Safe. If there is only one lesson from the the whole of political and econom...
