The spelling with more legitimacy is Aluminum. Sir Humphrey Davy, its discoverer, called it Aluminum when he published his work Chemical Philosophy in 1812. Some anonymous dilettante (anonymous to this day!) thought, upon reviewing said boo

Almost half the country's voting-age population already doesn't vote. The ones who don't vote are hardly part of the solution.

Not sure what the reasoning behind it was, but it now displays 11% less information per pageload, with no improvement (for me at least) to readability. Hopefully they can either justify it (no pun intended) or better yet revert it.

Did HN just get more whitespace between rows?

The trouble with most endothermic reactions is they involve far less energy absorbed per kg than exothermic reactions tend to emit (and their reaction rates much slower than you'd like). As a runner I'd not be too enthused about

Thanks for saving me the trouble of tracking down sources. The claim was inartfully stated at best. However, it all ends up going back to your definition of "net positive". I read "net positive" as getting more out tha

Oil is not a net positive on the energy; gasoline consumes more in electricity during the refining process than it contains; it's just in a much more useful form.

As an interesting aside, the leading use for hydrogen today, with over 50% of all hydrogen used, is in oil refining. That hydrogen (along with almost all the balance) comes from steam-reformed natural gas. It's also true that more ele

If you're not still encumbered by student loans from your first degree, then maybe taking some out isn't so crazy. With Math & Physics in particular, given that you're starting a bit late (even 18-year-olds struggle might

You're probably too late to get space in one, but a Chez JJ or similar airbnb where you sleep 6 to a room of like-minded individuals can be interesting (and a pretty cheap deal versus a hotel). Visit Hacker Dojo, Google's campus,

While the motors may be REE-free, I wouldn't be so sure about the rest of the vehicle. Many models of LED's, lasers, displays, headlights, and power circuits use trace but nonetheless essential amounts of rare earths. The motors

Procedure was straightforward. First, decide on the minimum accommodation you'll be able to live with (shared bedroom, own room, own room with own bathroom, studio, 1br, 2br, pets, no pets, etc.). Second, determine the hourly value of

Startups (ones that will eventually grow) need funding. There's arguably more startup-accessible funding available in the bay area than the rest of the world combined. There's a half dozen other factors, but most of them end up r

Solar panels can be regularly gotten for under $0.80/watt these days. You'll have to spring for over 150 watts to get that price range.

It's been posited that people would live on average to 200 just from unnatural causes of death (accidents, etc.) The way to live forever is to not die of something first. Aging is merely a combination of natural processes we're o

That's just it- the alternative is never wasting the electricity; you wouldn't invest thousands to millions of dollars in half a system. Well, I wouldn't. Compression or liquefaction don't address the storage density is

With a number of companies, this already happens when you go through recruiters. You don't see how much money you're paying, as it's factored in before you see the offer. If you look at it from the perspective of the employe

Concentrator cells make a number of tradeoffs in order to make their performance as high as possible (and keep from melting, etc.). I would guess around 22% efficient in one-sun AM1.0; that's about what other concentrator cells in thi

In practice it's pretty bad; Hydrogen, even compressed, takes up a large amount of volume. A 10 gallon tank stores about 1.5 gge of compressed H2. The energy to compress H2 is again as much as it takes to create H2, and you don't

Two tests- 1) Is your idea so great that not only you'll be making money with it, but someone else would want to knock it off so they could make money with it? If not, don't patent. 2) Are you prepared to seek funding for, develo

If I was a recruiter in the bay area, I'd guess you could find some B-grade talent who could knock that out for about $80k/yr., and A-grade talent for about $150k/yr. There's a whole litany of variables here, like where
