A single average-sized car puts out 4.75 metric TONS of carbon every year


Density of gasoline: 0.73 kg/L
Typical gas tank capacity: 57 L
Typical number of fillups per year: 52

0.73 * 57 * 52 = 2200 kg/year.

Gasoline contains various different organic molecules starting from hexane and running up through decane. Hexane is C6H14, so the carbon makes up 84% of the mass. Octane is C8H18, so the carbon makes up 80% of the mass. Call it 82%.

A single average-sized car emits 1800 kg of carbon every year. Less than 2 metric tons.

Numerous Methane Leaks Found On Atlantic Sea Floor 273

Posted by samzenpus
from the bubbling-up dept.
sciencehabit writes Researchers have discovered 570 plumes of methane percolating up from the sea floor off the eastern coast of the United States, a surprisingly high number of seeps in a relatively quiescent part of the ocean. The seeps suggest that methane's contribution to climate change has been underestimated in some models. And because most of the seeps lie at depths where small changes in temperature could be releasing the methane, it is possible that climate change itself could be playing a role in turning some of them on.

I have no doubt at all that Oracle committed fraud and lied a lot. I have no doubt Oregon's project management failed to give adequate oversight to the project, failed to adequately specify the project, and repeatedly changed what little specification they provided.

Neither matters. I have no doubt this lawsuit will ultimately fail, because the Oregon attorney general doesn't have the technical ability to prove the fraud and lies. The state has already proven they don't understand what they're doing. We're about to get a second demonstration.

Is there no end to the Elon Musk worship on this site? Once again, SpaceX does something perfectly normal and ordinary that's been done for decades and the fawning by corporate shills starts immediately.

What corporate shills? SpaceX is not publicly traded. They're privately held and self-funding from their own profit. What is said about them on random Internet discussion forums has absolutely no affect on their continuing success or failure. They will have to have a satisfactory explanation for the contracts people who have put down heaps of money to buy launches, but none of those conversations will involve random Internet discussion forums.

We're spectators, having a rather short and noncontroversial discussion about a small explosion in the sky. What are you, that you feel obliged to shit on the subject? A corporate shill perhaps? Employed by a SpaceX competitor?

Probably not. You're just a random Internet misanthrope.

The weight of lithium is pretty irrelevant. There are no currently existing battery technologies where Li is more than 10% of the total weight of the battery, and standard battery types are significantly below that.

He was probably referring to the elemental weight, not the weight used.

Some new game changing battery/supercapacitor breakthrough might be just around the corner. If so, all that investment in the battery megafactory could get wiped out. Ditto with investing in lithium mining.

It's not much of a risk. Every single battery chemistry has been played with, at one time or another. And by that I mean rigorously and exhaustively scientifically investigated. In consequence, not only has everything been tried, but we now know what works and why it works. That's why it's science, and not merely engineering.

Lithium will always remain a preferential element because it's the element that is the strongest reducing agent in the periodic table, short of hydrogen, which is too hard to hold on to. The stronger the reducing agent, the higher the voltage a cell can develop and the better a battery can be. At the other end, you want a strong oxidizing agent. Fluorine would be ideal, if it wasn't such a viciously strong oxidizing agent that it eats your whole battery, not just the electrons you want it to. Presumably this situation is what the spokesdroid was referring to, without explaining what the hell he was talking about.

Lithium is the cathode of choice since it's a metal that can be conveniently nailed down while still possessing a very good electrode potential. As an ion, it's nicely compact, being the lightest of metals, so it migrates through a battery most conveniently. What to pair it with is a little more complicated, and the subject of much research. This is where manganese, cobalt, and carbon come in. Various combinations of those elements and their immediate neighbors on the periodic table are used to make anodes. Some work better than others. Some may work better yet depending on how they're assembled.

Rest assured, whatever develops in terms of battery assembly, lithium will remain the cathode, and much of the macroscopic assembly will be the same or close enough to the same that the gigafactory will always be busy. The assembly and packaging to be done is fairly common, regardless of chemistry.

You're probably correct, at least for the prospects of an initial outpost. Except for freezing sewage. I can't imagine they'll ever have excess sewage to freeze. All that water gone to waste. Not to mention valuable nitrogen and readily metabolizable organic material. More likely it will get processed and its constituent parts reused, and fairly quickly. Yes using human waste as feed stock for food plants is a little risky, but the chill and near vacuum conditions allow for industrial processes that could mitigate the risk rather cheaply. It certainly won't be an option to once-through all that material. A closed cycle will be required.

Cubes do seem to be likely, for an extended period, despite the issues with pressurizing them. Ease of precise assembly and speed of assembly will be the watchwords for building pressure vessels.

In any case, it'll be Elon Musk making the real decision. I suspect hexagons will get short shrift.

Notify customers of these big ISPs that within two months they will no longer be providing the full service via that ISP.. sit back and watch the ISPs customers leave in droves.. of course, this is just turning the tables on the ISP net neutrality rules, but when the ISPs are already playing hardball and have their own man in charge of the FCC, then it's time to give them a taste of their own medicine.

You forget who Comcast owns. They wholly own NBC and Universal Studios, two major sources of Netflix content. And they're already screwing with the availability of NBCUniversal content on Netflix. If Netflix tries to play hardball, a whole boatload of shows and movies will just vanish out of their catalog.

A media company that owns the last mile is an abomination, and the FTC should do something about it.

Nobody has been able to explain what correct usage is, however.

The Chicago Manual of Style has detailed explanations of correct comma usage. So does Strunk and White's Elements of Style. You can also look up individual recommendations. Things like the Serial Comma have Wikipedia articles that quote both of those sources as well as half a dozen more.

Commas to delimit prepositional phrases have only recently been deprecated. I was taught to use them as well.
