If burning metal powder as fuel sounds strange, the next part of the process will be even more surprising. That rust can be regenerated straight back into iron powder with the application of electricity, and if you do this using solar, wind or other zero-carbon power generation systems, you end up with a totally carbon-free cycle. The iron acts as a kind of clean battery for combustion processes, charging up via one of a number of means including electrolysis, and discharging in flames and heat.From Dutch brewery burns iron as a clean, recyclable fuel
“Humor often involves identifying contradictions and revealing new perspectives, which suggests that the less you are in touch with reality, the less likely you are able to identify that something is amiss. This is because rational thought often depends on the ability to view a situation from multiple angles to get a less biased overview. If you are practicing self-deception and blocking out certain angles, however, you will fail to see the contradiction and therefore fail to enjoy the humor when these viewpoints are challenged. Leslie Savan, writing for the Nation, has speculated that Donald Trump is likely to be highly self-deceptive because he is almost never seen laughing. But what’s good for the goose is also good for those on the other side of the political spectrum, and I would make the same point about some of my colleagues in the cultural anthropology department whose apparent inability to detect any sort of humor gave me the idea for the study in the first place.”From How America Lost it’s Sense of Humor
Pick your core business competencies and goals, and do those in house. If you’re a software company, writing excellent code is how you’re going to succeed. Go ahead and outsource the company cafeteria and the CD-ROM duplication. If you’re a pharmaceutical company, write software for drug research, but don’t write your own accounting package. If you’re a web accounting service, write your own accounting package, but don’t try to create your own magazine ads. If you have customers, never outsource customer service.Joel Spolsky, In Defense of Not-Invented-Here Syndrome
