It's Iron Oxide. Specifically a magnetite-based composite.
And I don't understand how precipitation of iron oxide followed by phase transformation etc can be applied to the silicon used in photovoltaics. It's not like the two (Fe and Si) have the same chemistry.
You must secretly be an asshole, waiting for your day to shine. Power attracts certain dysfunctional personality types. It's not that good people are so rare but it is so rare that good people find themselves in powerful positions.
This is the most unfortunate problem inherent in any democratic system. The rule of the petty tyrants.
And it's easy to understand why: good people find better use for their time than power games.
I have a document in my backpack; my personal ToS. It states that everyone who shakes my hand must give me $20. By shaking, they agree.
Even if they were it still fails for lack of consideration: the other party suffers a detriment both in paying $20 and in shaking your hand, so the consideration only flows in the same direction... twice.:p
Easy fix: switch the places between the hand and the ToS... put the hand in the backpack (detach it if necessary) and offer the ToS to be shaken.
There are all kinds of CNC mills and routers. A lot of the really cheap ones are mainly good for working on wood or plastic, or are kits. Lots of people find an old mill/router and convert it to CNC. If you want a plug-and-play desktop mill or router there are a ton of options. Here is a fairly typical one that looks like it is capable of some serious work, $700.
Thanks, mills I found plenty in the price range. However, no lathes for under $1k.
Nah... US will return to the moon in 2015. Just after NASA builds a vehicle to replace the retired space shuttles, in 2014; it will be called "Crew Exploration Vehicle". And, once on the Moon, the Americans will start building a permanent base there, as an avant-post for manned missions to Mars.
Nice re-reading science-fiction classics, especially George W. Bush.
On the other hand, I can't deplore enough the change in the mind-set. From

to why send humans when you can just send robots... in only 50 years.
Thank you indeed. After searching the net for such, I sorta reached the same conclusion... good to see it confirmed (i.e. not caused by my inability to find the correct places).
Same for the lathe. Ether tiny or very old.
Confirmed. CNC lathes are even more expensive than mills: nothing under $1k, in $1k-$2k range I found only something I'd classify as "micro" - 20 mm max diameter, 135 mm center distance.
Further than that, realize that all of this energy stored in anything "grown" is from the sun so you can put an upper-bound on maximum POSSIBLE yield by determining how much energy the Earth receives in sunlight, multiply that by the efficiency of a plant storing this into whatever the input of some "process" is and...
What surface of vegetation would convert (by photosynthesis) the same amount of solar energy as the one consumed?
* Solar constant: for simplified calculation, 1kW/m.
* a flat patch "stuck" to the Earth surface captures during the day only 1/PI of the incident flux (assume equatorial position; take the "cosine law" and integrate between "dawn" and "dusk". Divide by the whole duration of the day). For an year, the "effective exposure time"=365*24*3600/PI= 1e+7 "full sun seconds".
* Photosynthetic efficiency: for simplified calculation, 5%
Equivalent power needed: 4.60548E+20 J/1e+7 "full sun seconds"=4.60548E+13 W=4.60548E10 kW.Because 5% conversion efficiency, we actually need 9.211e+11 kW. The surface needed to capture that much: 9.211E+11 m=9.211E+5 km. For comparison: Amazon jungle area=5.5e+6 km.
... and you will likely realize that this is completely impossible since we are currently burning more than one day (probably some number of years) of "stored sunlight" (oil) per day just to live our current lifestyle.
Let's try a Reductio ad absurdum: suppose a nation made of the sole "rich child Stephen Hawking" and 299,999,999 uneducated others. By your "scientific" methodology, to reach 50%-50% proportionality with the other countries, the poll would need to take the (sole) genius and a single other person. Because of the presence of the genius in the poll, the ranking of that country will be the highest possible. Question: does that (highest) ranking offer any value in assessing on how well the country will fare as a "leader" in the future?
This just means that the US has extremely rich kids, who are smart, but their smartness doesn't matter since they have no need of it to live comfortably.
And extremely poor kids, who are dumb, so their willingness to overcome the poverty - and, side effect, contribute to society - doesn't matter, them being locked into their dumbness
Extended your statement with their logical consequences. If you are rich... err... smart enough, draw your own conclusion (while your socio-economic class still exists)
But for a given question, what grounds are there to privilege the viewpoints of those whose expertise is not in a field of direct relevance to that question?
The capacity to apply critical thinking? Which probably leads to conclusion of "I don't know enough" - if the scientist attempting this is outside the area of expertise required - but nevertheless will show what other things need to be known to reach a conclusion. BTW, critical thinking is something that most of the politicians don't show/use in their exercise.
... would any machine running Windows be attached to or associated with anything that was critical to the operation of a power plant?!
Just in case you are scared about power plants failures - don't! There are much better things to be worried about.
For example - only a bit more that 4 years ago, the UK Navy finished retrofitting its nuclear subs with... Window XP and 2000! For sensors and weapons control no less. At the time,/.ers coined a new meaning for the BSOD.
Afterwards, we can privatize the health care entirely (mental included) and let the corporation pay/manage the police force... errr... (delete! delete, I say!!! never mind)... mental health workers. Any other idea on how to deal with the other executive powers? (ummm... say... attorneys. Too many of them enforce the laws too strictly and can be quite expensive to bri... pardon me, I'm not entirely myself today... I mean, quite expensive to support, and one can't create enough jobs with them poking their nose around).

If nobody has jobs anymore we better transition to an economy where everything the robots produce is free.
If nobody can pay for what the robots produce, the robots will produce only soylent green.
