Re: 1779: "2017"

... and probably every new year forever will just get worse and worse until i just die Well, yes. Even apart from the particular oppressions that have come over you, each of us will die, and so will everyone we love. Hope is a two-edged sword. Primo Levi (The Drowned and the Saved) describes hope a...

Re: energy currency?

sometimes it's impossible to find anyone who would be willing to give you anything at all for your energy because there is an abundance of supply but no way to store it. Negative energy prices, which are a symptom of nobody willing to buy energy for anything more durable, happen all the time and th...

Re: energy currency?

The point is efficient use of resources. That's the point of trading things, right? That's what currency is. An energy-backed currency is all about the efficient use of energy as a resource. The depreciation is tied to energy storage. This is what improves efficiency. If you can find a productive us...

Re: energy currency?

@Zamfir, you're right, I don't have an answer, I was just going back to the fundamentals of currency. Okay, how about electronic tokens valid for "today only", "this month only", and "this year only". Backed by a government that used tax money to build a big solar elect...

Re: energy currency?

first read about how the current system of currency works Honestly, that's where this is coming from. Karl Polanyi, "The Great Transformation" (1944), is about the three fake commodities that the market system is built on (labor, land, and money). The Wikipedia articles are a little thin ...

Re: 1742: "Will It Work"

The phrase 'depends on the phase of the moon' is in fairly common usage among engineers to describe an unexpected dependency, mostly due to its having been included in the Jargon File From which one caveat deserves to be quoted: However, beware of assumptions. A few years ago, engineers of CERN (Eu...

Re: energy currency?

So, at 3AM I can get energy coupons for free, because energy is usually for free at that time, and 3PM I can go shopping by using them? Fair objection. If you built an economy on "consumable currency", it would look pretty different from our present economy. People have suggested self-dep...

Re: energy currency?

Separate from the storage problem, I think it's very valuable to think of "money" as a consumable, rather than as something persistent. Our most basic need is for food, an incarnation of energy, which needs to be continuously produced to keep us alive. So our needs really look much more li...

Re: Should We Try Solar Radiation Management?

According to the following article 1 kg of SO2 can offset the warming effects of several hundred thousand kilograms of CO2: That article is somewhat short on numbers and references. However, it does lead to a presentation that includes some numbers: http://www.cfr.org/content/thinktank/GM_CFR_brief...

Re: 1742: "Will It Work"

I hate seeing App Store on the likely end of the "will it work scale". I want to yell, "yeah, and you know why?" Because it's not working for you . It's working for the plutocrats who gave you a closed platform that you don't control. You bought it. Now it's working. You're worki...

It's nice that programmers get to be the real adults for a change:

Re: 1737: "Datacenter Scale"

I don't think this is true: the remaining lifetime for a working bulb currently in a fixture is the the same as the total lifetime for a new bulb that could be installed in the fixture. They definitely age. You can see the dimming by installing a new tube next to an old tube. My kill-a-watt meter te...

Re: 1732: "Earth Temperature Timeline"

On the subject of liquid fuel for transportation, I forgot to mention that the Mars 2020 rover is now supposed to include a one-cubic-foot demonstration that will break Martian CO2 into O2 and carbon monoxide. It'll analyze the O2 for purity before venting it back to the atmosphere. Of course, the b...

Re: 1732: "Earth Temperature Timeline"

Transportation is about 1/3 of overall energy usage (the other thirds are, approximately, the electricity grid and home heating). Stored energy density is certainly what drives transportation towards liquid fuels. Zero carbon probably does mean you have to get by with a lot less transportation, but ...

Re: 1737: "Datacenter Scale"

The fluorescent tube example works because those things age at a definite rate. After a few years, a 40W tube will draw closer to 22W and be pretty dim. You can use a Kill-a-watt meter to measure that. I'm not sure the mean-time-between-failure for computers works the same way. Yes, they tend to go ...
