To Scale: The Solar System

spawnflagger says...

a few (perhaps dumb) observations:


  1. good thing Pluto is no longer a planet
  2. This video would've benefited from being shot in 4K
  3. Was a nice touch to show the orbit of Uranus as a giant fart cloud

How to drift a bathtub on a Hillclimb Race!

The comments on the Jalopnik article are completely full of these:

  • We need to shower this guy in praise.
  • It's a pretty clean build, that's for sure.
  • I wonder if he drained his bank account on it.
  • It was probably a wash.
  • I soap-pose anything’s possible.
  • etc.

Our Greatest Delusion As Humans - Veritasium

Real Time - Dr. Michael Mann on Climate Change

Asmo says...

Heh, no, I said we are capped at 5 KW/h input, our product midsummer is around 35-40 KW/h @ 8 cents per, or $2.80 paid to us (assuming no rain/clouds, winter is closer to 5-12 KW/h per day). Then from 5pm-about 6am, we buy energy back at 36 cents an hour. And as the wife and I are both working during the day, we use the bulk of our energy between 5-12pm, meaning any profit we make during the day is completely overwhelmed (eg. 20 KW/h @ 36 cents = $7.20). I live in Australia where the days of 45 cent feed in tariff are long gone (and further, it's a false economy where non solar users are subsidising that tariff for the few fortunate enough to take advantage of it).

Even with the 4 grand gov. rebate (my system ended up costing ~$12,000 AUD for 6KW), it's not likely to make the money back prior to the end of life for the panels (25 years) if electricity prices keep rising without the feed in keeping pace. Add a battery system so you can load shift from daily production to cover nightly usage (where the real cost kicks in) means that you'll be running at a significant loss over the same period, as you'll probably have to replace lead batteries at least twice over the life time of the panels. Even if hydrogen fuel cells or some form of Li Ion battery becomes far cheaper, it's still loss making for the owner, subsidised to boot and the cheap manufacturing is because the panels are produced in China where even the most efficient of factories are utilising enormous amounts of carbon resourced energy, materials that are carbon intensive to make and manufacture etc.

I'm not saying solar is bad because I want it to be, I'm saying it's very easy to sell to people to make them feel better, but like any "too good to be true" story, there's a hell of a lot more beneath the surface than most people realise.

As for nuke and hydro, yep, they have downsides, but they are the most effective sources of energy in terms of return on energy invested that we have available to us at the moment. And the damage of hydro, if it replaces coal burning facilities, might be significantly less than the damage from allowing GW to continue to run unabated.

I don't understand. If you are selling at 5kw/h during daylight, why are you seeing only slight decline in your bill? It should be near zero, if not a check written to you if you are careful to not use much at night. I went from $4-500 per month electric bills (we have an electric hot tub that sucks major juice) to $30 bills in summer, and under $100 in winter. My system cost around $40K, and I got back around $5K (and lost out on tons more because when I bought it the tax rebates didn't roll over and I didn't use them all). I live in N California, where it's incredibly foggy, and it still took under 9 years to pay for itself in savings. Had I been able to use all the rebate (like you can now, it rolls over until you use it up) it would have been a year earlier paying itself off. Since the system should last 20 years, that's a great deal, even for you at 11-15 years to pay itself off, that's still 5-9 years of free juice, and 20 years of never losing power (if you have batteries).
Another benefit is from decentralizing power production. That makes you immune from most failures or any possible attacks on the system.
I do agree, it's not a perfect solution, and not 100% pollution free, but it's a great solution for most, if done right. The carbon costs are relatively small, and a one time event.

I'm all for nuke if done responsibly, which means not on coastlines, built with failsafe design features that don't require power to halt the reaction and store the fuel, and not experimented with to get a bit more power out (which caused Chernobyl and 3 mile island as I understand it).

Hydro, on the other hand, is always incredibly damaging to rivers, which along with providing the water we need, feed what little wildlife we have left. I am against any new hydro projects and advocate removing the failing one's we have now. They are short lived under the best of circumstances, but the damage they do is often permanent.

That's certainly possible, but I can think of other plausible explanations:


  • Spain's problems mainly involved real estate and non-productive investments. Maybe Greece was doing a better job of employing the borrowed funds, and therefore lost more with their removal?
  • Spain's austerity program started in 2010, their bailout was in 2012 but they left the program in January 2014. You can clearly see the dip in GDP during that timeframe, although as you say it does seem suspiciously small. Perhaps the effect of austerity was actually greater in Greece because the initial recession was deeper and the period of austerity was greater?
  • Spain's economy is more export focused, which helped offset the impact of reduced domestic demand (although at 33% of GDP vs 28% of GDP it's not enough).

radx said:

Take a look at these two charts, if you have a minute.

Spain: left scale is GDP (green) and industrial production & construction (black), right scale (inverted!) is unemployment rate (red)

Greece: same data, same scales

Unemployment tracks industrial production & construction in Greece and Spain, as you would expect. And so does GDP in Greece, but not in Spain.

Why?

It's too big a difference to not wonder if someone's fudging the numbers here to make it like austerity did the trick for Spain.

Is Climate Change Just A Lot Of Hot Air?

bcglorf says...

Or maybe we tackle this from 180 degrees.

As opposed to what is happening, or how likely, we may find common ground on what it is we should actually be doing.

I've already made the suggestion of electric vehicles and fission, fusion or renewables in place of coal as the road away from emissions. Specifically improving li-ion batteries as Tesla is doing is a major step. Researching sodium-oxygen batteries would be even better as they can hold 4-5 times the power and have cheaper materials and recent results have us close to making them viable, so I'd like to see gov money directed there.

For power solar and wind are currently only cost-competitive because the scale is small enough that we get away with treating coal plants like giant batteries covering our baseline. They simply aren't cost effective to scale up for base load yet, and not likely to be for another 10-20 years. We can have a lot of nuclear plants built in that time. With electric cars coming into the picture, we're also going to need that extra electric capacity. I again would strongly encourage more gov money going into French style large scale nuclear power deployment. China's already doing it, even they've had enough of their current coal literally blocking the sun in the sky on them and nuclear is part of their clean air push. We should be encouraging that and following suit out this way.

I also wasn't kidding about Lockheed-Martin's fusion research. A lot of new ideas are out there for fusion confinement plans and Lockheed has publicly declared their intentions to have a demonstration reactor in 5 years time. I'm hopeful, and if that pans out, the roll out of truly cheap and clean power will start in the next decade for the sole reason that fusion under cuts coal for price.

Part of me reason for these measures versus more drastic ones is we need to keep our economies growing because regardless of what we do the next 30 years, the oceans will continue rising that entire time and the mitigation measures we're going to gradually be spending more and more on are gonna required us to have the money to do them.

If anybody's got better suggestions I'm all ears.

Welsh... mental language.

Seriously, look at this town name: Llanelli.

Looks like it should be LA- NEL-EE, right?
Nope, it's clan ech li. Goddamnit Wales, there is no 'c' or 'g' in Llanelli!! You cannot go around making up spelling!
