Where do I get TCO heat? I only have the typical BTU heat here.

You really don't have to prove that you're a dumbshit. We all know you're a lefty.

Are you worried about mind control rays and chemtrails?

There's tons of shit about that online too,

fink knot.

octane condenses at about 125C water at 100C and butane at -1C How is there butane mixed with octane under the sea?

certainly not by a successful $500 experiment.

To a chemist it's organic, but to a paleontologist or geologist it's inoranic.

If you claim is right your colclusion isn't just make the collector 4 times bigger. and two stops down is still plenty.

yeah, thus, silicon panels work fine down to the near infrared somewhere are you trying to mkae a point?

So, octane condensed first, the oceans came right after that,

There is also a pressure issue, butane is soluble in water, it is heavier than air and will stay on the the surface.

There may be other reactions, or other reactions in the process of it appearing in the form we see now. I had a car running on LPG, in winter a mixture of propane and butane so it will stil burn...

But our chemical Ph[D] refused to give his 'pinnion for less than a zillion cents,

Some butane could come from deeper in the earth ... Or it could have come down with with the H2O.

You just wait and see, give it a few thousand years, or maybe the species will simply go extinct before that,

But from plants? You gottobe a believer (not a rare thing among homapiens). And wtf do I care No use arguing with 'religious beliefs'.

That explains it (not).

We have a pumped storage system here in Missouri. They have a lake on top of a mountain, 800 feet above a lower basin and river. They pump the top lake full every night, and generate power from the water coming down every day. The facility got wrecked some years ago when the overfilled the top lake and it broke down the wall atop the mountain. They have rebuilt the system, so obviously it was still economically viable. They had to pay a HUGE fine for their screwup, too.

Pumped storage has been around for year. It's still expensive.

was started in 1974 and has been running since 1984. Efficiency is about 75 % - it costs you about 130 kilowatt hours of power to pump up enough water to generate 100 kilowatt hours of power when it flow back. It is currently used as a STOR (Short Term Operating Reserve) system to cover the brief sur ges of demand between TV programs, when millions of viewers all put the ket tle on at roughly the same time.

So can all "organic" chemicals! This was first proved beyond all doubt in 1828 when Wohler synthesised urea CO(NH2)2 by reacting silver cyanate with ammonium chloride in a double displacement reaction.

AgNCO + NH4Cl -> (NH2)2CO + AgCl

Thus knocking on the head the vitalism theory of organic chemistry.

We just find it a lot more difficult as synthetic chemists to make the right pure stereo isomer when compared to natural living systems.

Although it is true that hydrocarbons could be formed directly from inorganic starting materials the resulting fossil fuels would not have the preferential signature concentrations of lighter isotopes of carbon present in the products of photosynthesis. Looking for fractionation of isotopes is one moderately reliable test for the existence of life.

It is this stable isotope ratio coupled with GCMS that enables oil from different sources to be distinguished. It can also be used to find wines aldulterated with C4 cane sugar rather than grape juices.

It is however just about plausible that some simple hydrocarbons like methane and ethane in the deep Earth predate organic life. Plenty of methane and ethane on Titan and there is no evidence of life there. UV light and/or electrical can generate more complex compounds from these starting simple starting materials as in the Miller-Urey experiment.

The mass spec experiment on the comet lander would have been very interesting in terms of how dirty a dirty snowball actually is.

Hadn't heard of these--'flow batteries.' A-H capacity is set by storage volume of aqueous electrolytes, hence easily scaled.

Filling stations could change out your electrolyte, quickly charging a car.

I wonder what would be the energy density compared to gasoline. I'd suspect it to be really bad. Gasoline is burned 100% and the oxidizer component weighs nothing. And you can dump the waste products overboard.

The liquid battery has to carry both reactive components around, and their solvents, and has to lug the waste mass, too.

Energy density is unlikely to be impressive. On the other hand "dumping the waste products overboard" is what has given us anthropogenic global warmin g. John Larkin doesn't believe it in (though he does believe in evolution, alb eit a much clever version than anybody else's) but it's a real problem and not buring gasoline in cars is going to be part of the solution.

All true, but do you want a planet you can live on or a car with a long ran ge between refills?

Why not work it out for yourself? By the time twits like you have had to re cognise that burning fossil carbon for fuel is a bad idea, we may have got flywheel storage working, so working out the details of what we might do to day is something of a waste of time.

I was thinking of it compared to LiIon. This flow battery has 167 watt-hours/ liter versus 233 for LiIon, but the flow batt replaces lots of metal with water. Could be lighter. Maybe.

But it looks especially interesting for the thread topic. PV would be a lot more interesting if there were storage.

A home flow-battery unit with zinc and iodine in solution sounds pretty tame, cheap, capacity expanded at will with using larger storage tanks. They'll have to fix the dendrites problem.

Cheers, James Arthur

Batteries tend to destroy themselves. The liquid thing sounds good, if the membrane and electrodes can hold up.

But home storage (and home solar) don't make sense to me. The economy of scale is awful. There's a reason why few people have a coal-fired steam turbine generator in their garage.

-Lasse

Gasoline is rated at about 9 KWH/liter, about 50x better than that flow thing. Given the energy efficiency of an engine, we're in the guesstimated 20:1 ballpark.

tame,

A domestic gas-fired gas-turbine driven generator might make more sense, bu t they do tend to be noisy. They are being peddled in Europe as combined he at and power packages for apartment blocks and factories.

Solar panels on the roof do make sense. Adding sun-tracking, even on one ax is probably doesn't, unless somebody can invent a clever flexible mounting that flexes, rather than rotating a a shaft.

Home battery packs, if they could be made reliable and a very low maintenan ce - comparable with a domestic gas-fired central heating boiler - could al so make sense. About half the cost of the electricity I buy is paid out to the distribution system, rather than the generating companies. Cutting out that particular middleman would make solar power commercially viable right now.

The economy of scale involved is in the mass-manufacture of the parts, not in the size of the parts manufactured.
