I think you just destroyed your own argument.

Since I live in the middle of a agricultural district (Partly for this reason) I don't need to worry too much about long term stuff - I'm surrounded by assorted fruit, veg, chewable animals and freshwater in case anything biblical happens. Laid up in the garage I've got 10 day's worth of long life food, 3 days worth of water and 120 litres-worth of water treatment tablets (There's a small river 2 minutes walk away, so I'm not going overboard on bottled water. If it ever looks like drying up tha...

If anybody wants it, BTW, I've still got the Excel sheet I worked it out on. PM me....
I've spare you the math (mainly 'coz I can't type up the equations very well on DU) But the trick is to finding a balance between the gravitational pull of the sun, vs the pull of the earth, plus the force of the sunlight, plus the centripetal force. Which is fiddly, because the size of the sunscreen (and therefore the mass, and also extra variable in the sunlight pressure) varies as you move it around (if it's going to cover 2%, it needs to be bigger as it gets further sunwards) Anyway, it ba...

The low CO2 we've got today - or had - is mainly down to carbon capture: Generally speaking, Carbon spewed out from volcanic activity is gradually soaked up by plant life. The jumps in CO2 on the graph coincide with bouts of planetary flatulence: these are followed by a more gradual reduction as it get sequested into fossil fuels. The similar pattern we've got today just happens to be caused by monkeys, not volcanoes, but it too will get soaked up over the next 30,000,000 years or so. On your s...

I do like wind power, honest. But I got so fed up about the endless "we can get all out energy from wind" posts that ignore still days, I decided to price up the most likely non-hydro storage.
Since it's data that no-one seems to want to talk about, I've been trolling through meteorological records looking for non windy periods, and pricing a backup for wind power. What did I find? Wind power is almost free, but reliable wind power appears to cost at least $36 billion per GW. switching the US to just wind power would cost over $15 trillion. I'll be turning into a fan of PV at that rate... :) Now, these costs may be based on inaccurate data, but perhaps someone else would like to ...

Throwing this in as a glorified bookmark. I googled the current CO2 bulk scrubber cost, and applied that to the atmospheric CO2 over 180 ppm. Puts my mortgage payments into perspective, I can tell you...
Because cleaning up sites and disposing of wastes is actually possible, we get to bear the cost: If we were to remove the excess CO2 from the air and bear that cost - and with existing scrubber tech, ~$200 Trillion is ballpark figure - people might just realise just how cheap nuclear power is. For some reason, though, most people would rather shit in the bedroom rather than pay for plumbing. Rather disturbing, if you ask me.

If you're feeling suicidal, go and read the pointless non-thread that this came from. It'll help. I'm sticking this in the journal as a reminder that some people will believe anything, not matter how weird or wonderful. FSMism has nothing on this..
I used to post a bit on www.evcforum.net, where people with the time and patience attempt to spoon-feed creationists with a smattering of basic physics, chemistry, biology and math. It was hard work, because rather than make any attempt to educate themselves they would expect to have everything explained to them, in full, whenever there was something that required logical thinking. At first I used to think this was due to some deep-rooted desire to have all the facts, but as the questions got m...
