[@csdn4483]

Just a note on nuclear power - what comes out of a reactor is not waste, it's actually spent fuel. The reason it is called that is if you look at what makes up the spent fuel, about 0.5% by volume is actual waste (can't be used for anything). 95% of spent fuel is usable fuel (some U235, a lot of U238, some other fissiles created by neutron capture of U238, typically this is Pu239, but can get other things like Pu241, Am, and others). 2 to 2.5% of the spent fuel is usable isotopes in industry uses. 2 to 2.5% of the spent fuel is usable isotopes for medicinal uses. 0.5% of the spent fuel is waste that cannot be used for anything and typically has half lives that are 100 years or less. The actual waste can be safely contained for a 1000 years (we know how to do it) and after 1000 years it's no longer radioactive as it's decayed away. Source - my degree in Nuclear Engineering

[@MrTaxiRob]

@@seanhewitt603 because it's everywhere already, we don't need to build it out.

[@AndrewBlucher]

Hi Cn Dn, given your background perhaps you can respond to my concern: spent fuel is a small proportion of the waste, the bulk is contaminated equipment. Is this a reasonable position? Regards, Andy

[@secretnewmeta1981]

A physicist in Australia developed a method to remove nuclear waste from spent fuel using lasers. The patent was filed and immediately after was classified. We have the tech they just want it to be secret presumably for nuclear proliferation reasons.

[@csdn4483]

@@AndrewBlucher That depends. The largest bulk of radioactive materials is low level waste; this is things like gloves, wipes, etc that is used to clean up and/or used in medicinal/industrial use cases. The bulk of high level activated items cam be dealt with and stored as well, but it won't have near the long lasting effects that actual non-processed spent fuel.

Another home run from JMG, and the Event Horizon team, with this Robert Zubrin interview. Always, and I do mean ALWAYS, interesting to listen to Zubrin’s enthusiastic ideas about our future beyond the earth. Much admiration for Robert Zubrin’s ongoing and longstanding efforts to pull humanity into the future. A future that some human naysayers seem to resist, kicking and screaming as they go.

We're not going to colonise mars. There's not enough gravity to live there.

The big problem is how constant 1/3rd Gravity is going to affect human biology, particularly human reproductive systems. We currently have no idea how they will be affected. Assuming that there won't be negative effects is pure silliness. If we have to build O'Neil habitats to provide a 1 gee environment to reproduce in and raise children to near adulthood, that's a major complication.

[@peterplotts1238]

That's right. As far as I know, there is so far, no solution to the huge problem of long term human exposure to the low gravity environment. That doesn't mean we shouldn't pursue a mission to Mars, but that has to be solved before there is anything like a colony.

The idea that we're going to adopt a less regulatory, heavy nuclear energy model with a increasingly unpredictable climate sounds insanely dangerous. I think I'd rather see us throw way more money and manpower into earth based and space based solar energy.

[@secretnewmeta1981]

Nah. Every nuke accident was caused by under engineering or complacent oversight. The japanese built their reactor to withstand a tsunami which would happen once every 100 years instead of spending 5% more to make it good enough for once every 1000 year tsunami. This change happened because of politicians while the engineers screamed for greater durability. If we actually commit to nuclear and over engineer it then there would be no more accidents ever. The future is nuclear. Space based solar will happen as well and should happen but has just as many weaponization concerns as nuclear. Once we colonize out past jupiter we need nuclear for power. The light out there is just too weak. May as well develop it now.

[@secretnewmeta1981]

Self sustaining nuclear desalination plants will absolutely be essential in our future. These plants separate the deuterium from ocean water and burn it to finish the desalination process. Our fresh water is running out and these will be absolutely essential unless we depopulated to 10% of our current levels which may happen as well seeing as birth rates are plummeting worldwide.

Two problems: 1. Massive amounts of radiation on the surface of Mars, and nobody wants to live in underground caves/bunkers, or locked inside of artificial shelters for their entire lives. Perhaps there is an architectural and designing solution to this, but no matter what, you can't spend much time outside. This isn't easy to solve. 2. Lack of gravity. There's been little research on the effects of low gravity. We don't know exactly how much gravity the human body needs to remain healthy, or what the effects of low gravity might be on reproduction. We can't live in a giant centrifuge without vomiting all the time. Gravity issue may well be insurmountable.

[@laurencemoore8519]

Spot on. Mind you I`m sure that "genius" Musk will come up with solutions by just thinking them away. Your comment displays more thought than the entire broadcast by Zubrin. I notice he doesn`t even mention these problems. .

[@JohnMichaelGodier]

We live in a global culture where places like the upper slopes of Mt. Everest are littered with several hundred tourist bodies. Or the bottom of the ocean, the Titanic recently claimed more victims. Or the bases in Antarctica that are manned year round. Or the international space station which is a sealed environment where people live in space. Seems to me lots of people are fine with living in bubbles in extreme environments. As to doing it for life, well, that's not really the plan right now. The plan is for back and forth trips, and that's what the infrastructure is being designed for. It won't be for most people, but there will always be a contingent that will do it. .

[@laurencemoore8519]

@@JohnMichaelGodier I`d love to see a Mars mission, but its not going to happen any time soon no matter what Musk and others say. There are just too many obstacles to overcome. To go back and forth as you put it requires 7-8 refuel rockets per 10 or so people. Its just not feasible atm. And what physical state will those people be in after prolonged exposure to zero G`s or 1/3g for at the very least two years? So far if memory serves the longest anyone has stayed in space continually is just over a year and it took them some 18 months to fully physically recover. What will two years do to a human body, we just don`t know atm. Then there`s other considerations, just the caustic dust problem alone seems very difficult to overcome. Yes people might go to Everest, or the Antarctic but they don`t live 24/7 in space suits when they are there, they breath oxygen. If they go to the bottom of the ocean or a space station its a sealed environment how long do they stay there? Certainly not for two years and most certainly not for a lifetime. The nearest equivalent on earth to a mars mission is a tour of duty in a submarine. For every one sailor that serves another 100 apply but are filtered out due to physiological profiling. And by comparison that`s an absolute cakewalk compared to a 25 month mission to mars.

Sometimes scientists just need to look outside of their own field when promoting their technology.

In that scenario, the problem is tsunamis in the North Atlantic, not fission power generation. No one is saying that New York City is a looming disaster just because the ocean is going to overtake it eventually; the problem is the rising ocean, not the city. So what's the solution? Move them. Why don't we? Because of people who insist that tsunamis in the North Atlantic aren't the issue.

A Kilo of granite having more potential power than 100kg of oil is an incredible statistic. I live half a mile away from the biggest granite quarry in Europe. That's one hell of a lot of potential non CO2 producing power right there.

[@sjsomething4936]

I’m not questioning his math or the facts behind the claims about how much uranium exists in granite, but that doesn’t mean it is practical to extract it from granite for use. The other possibility is that the granite is just more valuable for use as a building material. I believe that most of the uranium produced today is extracted from relatively soft rocks or soils (often a kind of sandstone) and of course it is mined, exactly like every other resource. Mined (typically) from large open pit mines and leached out using a chemical process. There seem to be a few separation processes, but one involves sulfuric acid to separate the uranium from the non-valuable material. So while the _use_ of nuclear fission is non-CO2 producing, the mining and production of the fissile material most certainly is not, nor are the thousands of tons of concrete used to construct the nuclear power plants. Overall I’m a proponent of nuclear energy, but I am always angered whenever supporters of given energy technology X, Y or Z conveniently ignore the entire production chain that makes the power possible. Yes, lithium (for batteries) mining & production has issues very similar to uranium production, but overall it is cleaner than oil extraction and consumption, and is recyclable almost indefinitely as far as we currently understand. Yes solar panels are non CO2 emitting but they too must be made from mined materials, but also are recyclable. And nuclear energy is also non-emitting except the part where the mining requires plenty of energy input to obtain and concentrate it. All of the means of producing energy must be measured by the sum total of the CO2 they introduce into the atmosphere *plus the potential other nasty environmental effects they might have* from cradle to grave in order to get a true picture of their impact.

Most of this talk was great, but the one thing that made no sense to me was that, after dismissing current SETI methods, at 36:30 he suggests the best way to detect intelligent aliens is to detect artificial stars within 1000 light years. Personally, any technological civilization within that distance is 50/50, but an advanced one? Maybe he is talking about galactic time scales. Perhaps a number of these have been made over the lifetime of the galaxy, the civilizations that created them may have died out, and they are still orbiting the galaxy, and at least one is passing within detection distance of us. If so, I wish he had spelled that out. It is worth a look, I suppose.

Я думаю, ядерная энергетика на Марсе начнется вначале с урановой и на МОКС-топливе версии, а уже потом может перейти на ториевую версию. Для получения урановой версии АЭС на Марсе у нас уже все есть, за исключением некоторым специфических для Марса проблем (теплоноситель на углекислоте, отдача тепла в грунт). А ториевые версии АЭС еще нужно только разрабатывать и проектировать и строить, сначала на ЗЕмле, чтобы все отработать, и потом только на Марсе. В конечном итоге перенос части ядерных материалов на Марс позволит повысить безопасность ЗЕмли, потому что ядерные материалы, особенно плутоний, которые может быть более успешно использован на Марсе в составе МОКС-топлива, чем на Земле, может быть использован в военных целях. На Марсе же пока воевать некому и не за что, там угроза ядерной войны если и возникнет, то еще очень нескоро, через сотни лет, если там вообще возникнут разные государства. Ториевая ядерная энергетика должна возникнуть на Земле и заменить ядерную и потом перейти в космос и на Марс, это несомненно. Еще я думаю, что малые АЭС на ЗЕмле и на Марсе должны использовать для преобразования энергии из тепла в электричество поршневые паровые машины, а не турбины. Турбины для получения достаточной эффективности требуют более высокого градиента нагрева активной зоны реактора, что резко снижает срок службы топливых стержней и реактора в целом. Для поршневых паровых машин такой градиент заметно ниже, и их использование позволит продлить срок действия одной топливной сборки на порядок или более. Той же цели служит размещение АЭС в местах с холодным климатом, что позволяет повышать эффективность выработки энергии по той же причине - понижение температуры активной зоны реактора и топливных сборок и продление срока их службы. На Марсе это случится само собой по естественным причинам - там холоднее, чем на Земле. А на Земле мы должны строить новые АЭС только в местах где холодно - в США это северные штаты, Аляска, в Южной Америка - Патагония и север Чили и так далее. А вот в таких местах как Турция и Иран АЭС не нужны совершенно, и мы можем однозначно признать, что строят там АЭС по одной единственной причине - получить ядерное оружие, а не с целью получить дешевую энергию.

Thorium has the same issues as Uranium for a proliferation issue. The supposed comment from those saying we can't use Thorium for weapons, but the fact of the matter is this, if someone really wants the weapons grade material.

If we find out Mars has life exactly like ours (same dna), that would be incomprehensibly insane on so many levels. Some how organisms had a way of migrating across space, meaning life out in the universe, could be insanely vibrant. 😮

Art had great conversations with him.

I wouldn't want to live on a planet/moon with less gravity than Earth.

[@charlescook5542]

Even though astronauts exercise for hours each day their bones lose mass in no time. There’s no way humans are living on mars without genetic engineering which we don’t have yet.

[@robertadsett5273]

@@charlescook5542 we have data on zero gravity and 1G. We have literally no data on extended stays at values in between and AFAIK, no good theoretical model either. While certainly a concern that needs addressing it’s not a given that we cannot adapt to some lower values of acceleration

@@robertadsett5273 one of the highest altitudes people live at on earth is in south america at some silver mine, just from the lower air pressure they suffer unique health consequences, we didn’t evolve to survive everywhere

[@robertadsett5273]

@@charlescook5542 no joke, but that says nothing about how much gravity we need to maintain health. For that we only have two data points. We don’t need full atmospheric pressure, certainly 0.6 atm isn’t for everyone but the tibetans manage it so it’s within the human adaptation range, can probably go lower with oxygen enrichment. The question is how low (and how high) can gravity be for minimal affect on human health. Currently we don’t know, we only know that short periods of even zero gravity are fine, but long term zero gravity is a problem. Do we need 70% of earth gravity or is 10% sufficient, perhaps with additional exercise if we want to return to one g environments. I don’t know, neither does anyone else, although I can understand someone being very cautious of very low gravity given what we do know and we should be careful about lower than earth gravity until we have gathered data about the effects of low gravity on human health.

I agree with Dr. Zubrin, life on Mars, or any other terrestrial body in the solar system, is gonna be deep underground. I’m pretty confident it’s there. Rudimentary life only needed like 800 million years to exist on Earth, it’s almost like it happened as soon as it could, life is seemingly eager to exist. I think microbes could be common, but we have to dig for it. Scraping around in the surface regolith is a complete waste of time, in my opinion.

Dr. Robert Zubrin is such a quack

I enjoyed this and find the speaker interesting but disagree with a lot of his historical takes on the opposition to nuclear power in the past. He doesn`t even mention Chernobyl.. Here in Europe that event triggered a LOT of opposition to nuclear power, not some fly boy in a suit bribing others to make a buck. Then there`s the idea of the deliberate pursuit of malthusian politics in India and Ireland? i`ve studied British history for 50 years (and have a degree in the subject ) and have never heard that advocated before or even discussed in English universities. It may be in America but its sim0listic, plain wrong, nieve and flys in the face of recorded British history. In truth i find his historical analysis of America and the "new societies" on Mars generally wrong on a number of points. As regards Mars in ten years? Even a small team? Not a chance, there are too many problems and Musk is a marketer of genius but that doesn`t extent to other fields and hes certainly no rocket scientist(he pays others to do that for him). I find his HOPES on solving problems in the future to establish a colony on Mars (synthetic food-the new mana from heaven, AI advances, ect ect ) are just that, Hopes not fact. Then there is the effects of zero and low gravity on humans, which is a real problem, and he doesn`t even mention that. To my mind the only solution to colonising the solar system, and Mars, is to build O`Neil or Torus stations in lo orbit. Then the falcon heavies would come into their own, and everything is far more simple. Then once built they can be moved out to start colonies on Mars. Think of them as cosmic Galleons.

[@markp4967]

No, we CANNOT live on Mars. No gas stations, no bars, NO GROCERY stores, no liquor stores... Get the picture???

[@friendlyone2706]

Years ago I shared on a youtube site that some of the Martian rock deposits looked identical to drumlin deposits left on earth by ancient glaciers. Not long ago I heard a Martian expert talk about "ancient Martian glaciers" as though the acceptance of them had become standard. Perhaps the remnants of glaciers and old massive water sites are clues maybe someone (or something) terraformed Mars in the very ancient past?

[@CIVILDEFENSEBUNKER]

We literally have the solution already it's been around for 45+ years. TRIG Thermo radioactive isotope generators. These can be made small enough to charge electric cars, augment home power , home heating etc..
