    Yeah, I should have said "stress" instead of damage. In moderation, the liver can handle the load without trouble. But drinking a 64oz Big Gulp every day could lead to problems.

    I also switched to drinking water many years ago. I still drink fruit juice, but only in very small amounts. (I can make a 12oz bottle last a week.) I might say I have a semi-low-carb diet, if it weren't for all that beer. ;-)

    if you eat less, you will lose weight.

    Maybe so, but that doesn't mean your weight loss will be 100% FAT loss. On the contrary, consuming less calories can also cause your body to store up MORE fat, to compensate for the food shortage. Numerous studies have shown this effect... you just end up with a smaller "fat" rat than the control subject.

    Another factor that often gets overlooked in this debate is the role of sugar in our diet. (Here's a written summary of the video.)

    Last spring, the convenience stores in my area started stocking fresh fruit, so I switched my habitual breakfast from coffee and a Snickers bar to coffee and a piece of fruit. Around the same time, I saw the video linked above, and started actively avoiding sugar whenever it's convenient. These are the ONLY changes I've made to my lifestyle, but since then I have lost about four inches off my waistline.

    Sugar is toxic. Do yourself a favor and avoid it. (Did you know that a 12oz can of coke does as much liver damage as a 12oz can of beer?) And artificial sweeteners are even worse. They mess up your insulin response profile and impede the signals which tell your brain when you've had enough to eat. (If you have a diet coke with dinner, you'll likely eat more food.)

    The BBC did a four-part series on the "weight loss industry" earlier this year. It does a pretty good job of exposing the hype and marketing BS behind our current situation. Worth a look.

    I'll be surprised if there aren't tourists on the moon long before 2030. SpaceX's next-gen "man-rated" Dragon capsule will be flying in a couple of years, and the gap between that and a lunar landing/return capability is pretty well understood territory. It's not quite "off the shelf" yet, but there are plenty of folks working on the necessary technology.

    Although I fully support and applaud this effort, this is not the only way to get the job done. Permaculture design can achieve similar results with much smaller inputs, as described in this video.

    The most important concept of permaculture is water management. If you only get 8" of rain per year and it all comes within a 3-week window, you'd better have your land "sculpted" to optimize retention of water on the surface for as long as possible. Such improvements last for generations, and continually add fertility and biodiversity to the land.

    If we seriously applied these principles worldwide, we could make the entire globe flood-proof and drought-proof in less than a decade. Seriously.

    the known Uranium supplies are plentiful

    What? Although Uranium is fairly plentiful, the vast majority is U238, which is not fissile. The only Uranium we can reliably "burn" is U235, which is about as plentiful as Gold or Platinum. (That's why we "enrich" the stuff, to increase the portion of U235 over U238.) If we keep going at status quo, the current fleet of reactors will burn out the "usable" Uranium supply in a few decades.

    The big "revolution" in the next few years will be the transition from solid-fuel to liquid-fuel reactors. Liquid fuels can be reprocessed on-the-fly but solid fuels cannot. This is a HUGE advantage, because it allows us to burn the fuel completely with very little waste. Whereas the current LWR uses only 0.5% of the energy in the fuel rods, leaving hundreds of tons of long-term waste to deal with.

    Furthermore, a molten-salt reactor can be configured to use spent nuclear fuel as a fuel source.

  15. Re:Why livestock? on AgriRover Brings Mars Rover Technology To the Farm · · Score: 4, Informative

    There's a variant of no-till called pasture cropping which solves some of those issues by combining livestock with row crops. The field is grazed down once, then again a few days later, before the grass has recovered. This double-punch puts the grass in a semi-dormant state, so you can plant directly into the sod. As your row crops sprout, they'll have head start on the pasture plants, eventually shading them out. (They'll still keep growing, just very slowly.) After harvest, you can graze again or mow for hay, and the pasture will recover normally.

    As for livestock, robots wouldn't be my first choice either. FTFA:

    A livestock paddock, for example, may look uniform, but under the grass there’s a great deal of variability of soil and conditions. Levels of potassium, sulfur, and acidity can be very different even within a single square meter. The main reason is that livestock don’t pee or poop in anything like a uniform pattern

    A simple solution to this is raising complementary species in managed intensive rotational grazing as described by "Omnivore's Dilemma" author Michael Pollan in this video (10min). In a nutshell: the pasture is divided into paddocks which are grazed intensively for a day or two, then rested for a few weeks. The trick is to bring poultry into the same paddock a few days after the ruminants. Chickens (for example) will go after the cow patties and kick them apart to get at the maggots inside, and in doing so, they spread the manure very effectively while also keeping the fly population down. There's no need for an expensive robot to do this job when you can have another livestock species (ie: another revenue stream) do it for free.

    but it is still experimental

    LFTR is a variation of the MSR Experiment that ORNL ran in the 60s. The MSR ran smoothly for years and was found to be quite reliable. Most of the issues you raise were addressed in that work.

    having a liquid serve as both fuel and coolant doesn't sound like that great an idea

    It's actually a good idea, for many reasons. The ability to reprocess the fuel "on the fly" while the reactor is online is a huge one. It allows for near-100% fuel consumption and extraction of valuable isotopes. In an emergency, it allows you to rapidly move the fuel to a special tank designed to prevent reactivity and to passively cool the decay heat.

    graphite moderator has a nasty habit of burning in an accident

    It would take a core breach to get air in contact with the graphite. In that case, I guess you could flood the core with a heavier-than-air noble gas to snuff out any flames. Most of the discussion about graphite concerns other issues, like expansion, brittleness, and the reactivity feedback you noted. They would probably end up replacing the moderators on a 2~4 year cycle.

    the fluorides being suggested are significantly toxic

    A lot of industrial chemicals and processes are hazardous. OTOH FLiBe has the advantage of being a solid at room temperature. In a worst-case scenario (say a tomahawk missile strike) where the fuel salt gets blown out into the environment, it would be much easier to clean up, as it would solidify and fall to the ground. It's radiation signature and "unnatural" color would make it easy to find.

    I'd much rather have the coolant and moderator be the same thing, so that if you lose your coolant you're also losing the ability the sustain the fuel reaction

    I'd rather have the coolant and the fuel be the same: if you lose your coolant you're also losing the fuel (and the moderator too, if you think about it).

    Bottom line: MSR is a technology that has worked in the past. I see no reason to doubt we can get it to work again, and much better this time with all the knowledge gained in the meantime. Are there challenges? Yes, of course. But these strike me more as engineering problems than showstoppers.

    If you're going to "do" nuclear, at least do it in a sensible way. IE: Do NOT use solid-fuel LWR technology, that is just f**king stupid. If you use a liquid coolant that naturally turns to a gas at BELOW the working temperature of your reactor, you have a stupid f**king design. An "average" LWR has to operate at 100+ atmospheres of pressure, just to keep the coolant (water) in liquid phase. This invites a host of engineering challenges that would be completely unnecessary with a design (such as LFTR) that operates at ambient pressure.

    Unfortunately, the energy "marketplace" is dominated by big-capital players who are quite happy to suckle at the government teat to cover their outrageous overhead. Sadly, this is one area where "capitalism" has failed, big-time.

But methanol can use a somewhat wider range of feedstocks, and has the advantage of being a liquid, which is a better fit with existing infrastructure.
