The scale of this operation with 17,000 workers making small appliances is staggering.

Bridge Girder Erection Machine
Very cleverly designed machine cantilevers out to install a preformed bridge section.

Closer look at picking up and transporting the bridge sections:
And how about this Dutch machine where a robot 3-D prints a bridge in mid-air as it spans the river!

Why Porsche engines fail
IMS Bearing - The Full Story | Oregon Region Porsche Club of America
Camshaft bearing failures in model years 1999-2008 are a problem to be wary about, according to this article. Note that he points out that a gently-used car may be more prone to this failure: " Although there is limited data, the general trend is that lower mileage vehicles with infrequent oil changes or driven light-footed (as in run at low speed/engine rpms) are most likely to suffer a failure rather than those cars that are driven hard and well-maintained."

Strange words for a common thing.
Cullet is fed into the dog house, sheared into a gob, pressed into a parison, held over a deadplate, then cooled in a lehr.
Any idea what these words refer to? If not, watch how these things are made.

Clever stove generates electricity
Not only does this stove recirculate air to burn far cleaner, but it generates electricity with a thermoelectric generator.
http://www.biolitestove.com/products/biolite-campstove
However, reviewers are skeptical of its advantages. It is heavy, and it takes hours to recharge a battery...far longer a time than you would need to cook your meal. So it uses up excess biomass in the wilderness where resources are limited and human impact should be kept low.

Teff in Injera
Isn't it a shame that when an ancient grain from a country suddenly gains popularity, it only serves to accentuate poverty and malnutrition in the very country that should benefit most from its newfound popularity.
http://www.theguardian.com/global-development/2014/jan/23/quinoa-ethiopia-teff-super-grain
However, the article below makes a nice counterpoint...that the above article can undermine the good that is coming from a grain's newfound popularity if people are convinced to stop buying it for ethical reasons.
"It’s OK To Eat Quinoa Don’t buy the media’s hand-wringing about Bolivians who can’t afford quinoa. The real effects of Western demand are complicated.
..."The Guardian calls it "... a ghastly irony when the Andean peasant's staple grain becomes too expensive at home because it has acquired hero product status among affluent foreigners.

"There is, in fact, a ghastly irony here. It's when media stories discourage people from buying imported quinoa in the name of solidarity with the locals. But instead of helping, such reports threaten to kick the legs out from under one of the most promising industries in one of the world's poorest places."
