Yup, but for two big factors - CO2 in the depression would be heavier than the O2 in the surrounding air so the O2 wouldn't naturally flow in to displace it, and the instant the igniting torch hit the depression, the heat would have started mass-producing local CO2 from the sublimating block. So, no O2 in the area unless it was somehow broken apart from the CO2 in the block itself.

From Wikipedia
Diesel engine runaway is a rare condition affecting diesel engines, where the engine goes out of control, consuming its own lubrication oil and running at higher and higher RPM until it overspeeds to a point where it destroys itself either due to mechanical failure or engine seizure through lack of lubrication. For instance, a 1800 rpm engine can run to 4000 or 5000 rpm or beyond.
Several ways to stop a runaway diesel engine are to block off the air intake, either physically using a cover or plug, or alternatively by directing a CO2 fire extinguisher into the air intake to smother the engine.[

Acetic acid (C2H4O2) is what is most likely going to form for the extra CO2 absorption in the atmosphere into the oceans. And just like the egg here, it will dissolve the shells of microorganisms or prevent them from extracting calcium carbonate( CaCO3) from solution (ocean water)

If people don't want to plant vegetable gardens, then what about habitat for something to live in? Lawns are a wasteland for native plant, animal, fungal, and bacteria species.
Also, I don't buy the carbon sink thing. Powered lawnmowers put out a lot of CO2. Also, a lot of cut grass decays... and that releases greenhouse gasses as well.
Oh.. and 'pesticides' were mentioned, but what about herbicide and fertilizer run off?
OhX2... and lawns are reeeaaaally ugly!

Indeed, I am all for reactor simplification, the reactor I want to see constructed could theoretically be nearly completely made on a factory line then shipped and installed very simply. The molten salt reactor concept is just a bunch of pipes with a graphite core. Most of the Gen4 reactors have this goal, and while large construction projects do mean jobs, usually good jobs...they are also costs, and if we want China and India to adopt greener power systems, they need to be cheaper than coal.

I am going to sift this after I post, but it is a short look into reactors in general, and why the MSR and other potential Gen4 concepts could eliminate that huge capital and labor cost. And nearly completely eliminate radioactivity problems to the general public.

300 billion is actually not to much money when you get down to it. Each year, the global economy spends up to 10 trillion dollars on dino fuel technology. Considering the reliability of NPPs and the nearly 90% load rate over the course of many years...those costs are really really good! Typically speaking, when you consider the costs of decommissioning, waste transportation, nuclear generally ends up being about on par with coal...mostly because nuclear plants last so darn long, over 60 years for some of our gen2 plants in the US and still going strong! Compare that to the 150 billion or so Germany has spent on solar project to their total ACTUAL output and it is a very telling tail. Even more so when you look at total carbon emissions of Germany compared to France.

Waste is actually what made me anti-nuclear myself. My introduction to caring (negatively) about nuclear was the Fukushima Daiichi incident. But after learning more about that situation, I actually really started to appreciate nuclear more. No one died as a result of FD failure, the containment building stopped most of the most harmful radiation, and the stuff that did get out is the really mild stuff (stuff with the million year half lives). I don't want to downplay this, it is still a very serious industrial mess to clean up, but compared to the 20 thousand people who died in the Tsunami and the tons of fuels, trash and other crap that got souped around in Japan as a result, the old reactor help up respectably, and is a credit to the operators (all of whom are currently alive an well).

I had a common misconception about radioactivity, I thought something with a long half-life was bad because it was going to be radioactive for a long, long time. That is mostly wrong. What that means is it is going to be hardly radioactive for a long time, elements that are short lived are VERY radioactive, but disappear very fast. I don't want to mire you in most of the gritty details, but the fission products reactors produce don't last very long, most only hours, a fewer some decades, and only a few longer than that. Stuff that has billion year a billion year half life...well, you don't really need to worry about it at all, it just isn't that radioactive. Most of the worry is based around "transuranics". That is just fancy speak for "stuff heavier than uranium". This is the stuff like Plutonium and Curium ect. The great thing about modern, Gen4 reactors is they don't really make those things...the thorium reactor I like starts with thorium, which is a long, long way from making anything heavier than uranium (less than 1% theoretically possible). So micrograms per year...not really that much to worry about (there is also no way to really get that to go into the environment because we don't use pressure vessels, but I will leave that to Kirk to explain).

I don't want to make it sounds like there isn't any risk or anything, but the risks have been way overplayed by political interests and not technical ones. For instance, many of the exclusions zones for FD were way overblown, they were no more radioactive than my home in the mountains ...but that isn't want you heard in the news.

But I think I will leave it like that. Nuclear has a bunch of mystic joojoo around it. Don't take my work for it, please, give "bill gates nuclear" a google, or other "gen4 reactor" stuff a chance before you completely write off nuclear as a green option for the future. I personally think it will have a big role to play if we want to stem off CO2 production AND bring more people into a western quality of life. Thanks again for the back and forth.

KnivesOut is correct, yet keep in mind that "clean coal" does next to nothing to reduce the amount of CO2 released from coal combustion. It also does nothing about the dangers of mining coal, as mentioned by Sagemind, and does nothing about reducing the contamination of the environment via mining.

Wouldn't the dry ice they're using bring the water temp. down so fast it would throw the fish into hypothermia or shock?


Not to mention raise the CO2 level to suffocate the fish.

Commercial application is all about the intersection of increased profitability for a business and the factors people want to pay for.

Fast is a factor but only one factor. People want faster but they are also scared of fast, but likewise they'd rather flights we're cheaper, had more leg room, had better amenities etc. Businesses want to move more people at a time at less cost - especially if they are going to start paying for CO2 and increasing fuel costs.

You get so far and then improving a single factor just has diminishing returns unless you totally disrupt the whole model.

So the land development, building and fueling/mining of a nuclear power plant is free of emissions? What about waste disposal and decommissioning? Bremnet speaks the truth, albeit in a markedly sarcastic way. Car emissions come from energy production. Electric cars simply have their energy production out-sourced. Things become interesting at a local level with electric transport because you can potentially choose how your energy is produced. But you'd better believe that coal and oil is still powering all things electric in the majority of households, including recharging batteries.
I am a huge proponent of nuclear power, though I really wish LFTR's would come into production especially considering it's organic safety features and relative fuel abundance.
Since we're on the subject of electric cars, don't forget that the production of batteries and electric motors is very expensive. I'm not necessarily talking about monetary costs, but rather cost in resources and energy. Again, I support the development and usage of electric vehicles but dare not ignore their true cost.
>It seems the only answer that comes up is carbon credits and absolute emission limits.
You have so much more power to control your resource usage than the government. Don't rely on them for a solution. You can choose what you eat (agriculture is a huge resource spender), how you travel (walk or take public transport), what and why you buy (industry is another big spender), and your home resource usage. Don't pass the buck and blindly empower the government when it's our responsibility.
Now if only the planet was run on pancake power. Then, surely, I would be the true master of Earth.

Well, nuclear is there to make electricity and vehicles emission free. If the greens hadn't worked so hard to ensure that nuclear power was stopped the 41% for electricity and whatever chunk of transportation is vehicles would all be gone.
But fine, is you wanna be sarcastic how about you chime in with a better solution. You hear plenty of chicken little's running around crying it's time to panic. You hear plenty of talk about reducing our emissions. You don't hear nearly so much about how to do that. It seems the only answer that comes up is carbon credits and absolute emission limits. Without nuclear power for electricity production and switching large parts of transportation over to electricity, what is left? Are we just to stop using transportation and electricity all together I suppose?
>> ^bremnet:
Yes, so true. Just look at all of the countries signing up for new nuclear power plants. Oh, and of course, those who generate their electricity today with that peskily cheaper natural gas from shale gas will likely just shut that down. Forgot to ask, how do we generate the electricity to charge our batteries? If you say anything that involves rubbing balloons in ones hair, well that's just too clever! Let's see - in 2009, 41% of global CO2 emissions were from the generation of electricity and heat, and only 23% for transport per the IEA report (that's all transport - cars, trucks, buses, seagoing vessels, trains, planes) so let's call your 30% a rounding error. By 2015, it is estimated that the total CO2 emissions from seagoing vessels will surpass that for all land based automobiles, so can we get a video of an electric cargo ship instead of this car? Pretty sure they have those, right? If we have electric vehicles, and have to generate more electricity ummm... (head explodes). Top marks for enthusiasm, but I'm afraid we're going to have to keep you back for another year to re-teach math and energy balance.




But just how much can you realistically reduce your emissions by through changed behaviour? I doubt even 50% is realistic. Now, how about getting our entire society to do the same, are people gonna voluntarily give up everything they need to drop 50%? Not a chance.

If electric cars can be improved enough to be desirable over gas, then a switch over to nuclear for electricity production can drop emissions nearly 50%. More importantly, it happens by consumers buying something new because they simply want to, and government/corporations making money off selling nuclear energy to run everyone's new cars.

Short of putting guns to peoples heads and telling them what they can and can not eat, how far they are allowed to travel in a year, and enforcing that across the globe, emissions ARE NOT going to be lowered. Electric cars and nuclear power are the only viable options out there and they are either ready now(nuclear) or will be very, very soon(electric cars).

Good news everyone. The climate change problem has been solved!

Seriously, with electric cars so near to eclipsing gas we are very close to a landslide change of technology. Batteries are getting good enough that electric cars will very soon be better than gas in every way. Once that happens, gas and therefore oil, consumption will drop near to zero. Human CO2 emissions will drop by almost 30%, and for no other reason than people buying that new car they want. Any nation willing to adopt nuclear can at any moment drop off another 80% of what is left.

The technology stop human CO2 emissions is coming or already here, and people will adopt it without needing to frighten, scare or coerce them into it.

http://www.nytimes.com/2012/07/30/opinion/the-conversion-of-a-climate-change-skeptic.html?_r=2&pagewanted=all

Speaking of, here is a new modeling based in a statistical model instead of climate models directly. They concluded that warming is indeed happening, perhaps not as large as other models though. They even attribute the last 250 years of warming as man made, even as they were previous warming skeptics. Ironically, climate and weather are some of the hardest things model and yet, most important for continued life on this planet. With more and more studies showing CO2 being a large issue, it is a cry that is quickly becoming hard for the skeptic to ignore.

On that note, did you know that without the atmosphere, the earth would be −18°C? The Greenhouse effect keeps us alive, but as we can see with Venus, it can also make us dead. But there are about 8123918237912837 *citation needed* things that effect the weather/climate as well, so always best to be vigillant in that area.
