is that really any worse than working in a building that houses star-hot plasma contained only by the grace of an electrically generated magnetic field?

well the total amount of star-hot plasma in the system at any given time is only a couple of grams, and if it did breach containment you'd just get a big flash of light and then nothing. i'd rather be in the room with the tokamak than the room with several tonnes of molten metal loaded with all that kinetic and thermal energy

that plasma just seems so ethereal whereas i know (relatively) what a mass of molten sodium looks and would probably feel like

total number of people killed by manmade fusion: i dunno maybe like 1 or 2 from h-bomb related cancers total number of people killed by molten metal in steel mills alone: uh, like tens of thousands

this is a surprisingly stupid middle school argument really, the critical failure modes for either are basically instantly fatal. thanks to our unending hubris i'm sure many people will get to enjoy one or the other

three words: internet of things as long as your water filtration system is maximally invasive and tweets/instgrams/logs and uploads everything that passes through it there's plenty of data for target hungry advertisers plus you can gamify water consumption! now with facebook integration

Its final core was an experimental, light water moderated, thermal breeder reactor and is notable for its ability to transmute (inexpensive) thorium to uranium-233 (the latter being the fissile material that fueled the reaction within the reactor core).[4] The reactor was capable of an output of 60 MWe. hahahhaha That plant still has two active reactors but they're PWRs.

I'm more amazed by the fact that any mechanical thing can rotate a metal shaft with 1 gigawatt of power I'm guessing a gigawatt nuclear plant has multiple turbine+generator pairs or something how the hell does that even work, like how do the turbine blades not get blasted off their welds? that's some serious loving torque, what with an entire Manhattan's worth of electrical load pushing back on the generator

so someone mentioned agricultural land restoration projects and yes yes yes 1) biochar. gently caress yes biochar. increases cation exchange capacity, water retention, has a shitload of carbon so throw a lil nitrogen on that bitch and u got urself some beneficial microbes going. do a biochar 2) loving great green wall bitches. basically acacia trees have real deep roots AND they fix nitrogen?!?! holy mother of gently caress these things are awesome already. but then THEN they totally LOSE THEIR LEAVES AT A TIME WHEN AGRICULTURAL CROPS ARE IN ACTIVE GROWTH. so u can plant MUTHAFUCKING CROPS under these trees and they wont gently caress with the root system, get fuckin NATURALLY FERTILIZED and can still get sun and poo poo?!!? plus ur CREATING MUTHAFUCKING JOBS AND DISTRUPTING THE AGRICULTURAL ECONOMY b/c u gotta harvest those bitches between trees and aint no loving big-agri mass producution machines doin' that poo poo. http://en.wikipedia.org/wiki/Great_Green_Wall 3) and gently caress this documentary is awesome even if it gets all preachy at the end http://www.symphonyofthesoil.com/ loving soil (it is not dirt IT IS NOT DIRT) bitches, keeping things alive

Sagebrush posted:it's more amazing to me that a modern gas turbine-generator set can turn better than 60% of the heat energy in the steam into electrical power, entirely mechanically gas turbines don't use water, except in combined-cycle (brayton + rankine) systems that use waste heat from the gas turbine to generate steam . the ideal brayton cycle has a thermodynamic efficiency around 45% and the ideal rankine cycle is under 40%. These can both be increased with various funky arrangements (multistage systems and combined cycles) but neither is going to hit 60% solo, and that's before considering the mechanical -> electrical conversion (which is pretty drat efficient but not perfect). from what I can tell, real-world fuel to electricity numbers for the combined cycle are in the 50% range. Sagebrush posted:just imagine the existential question posed by working in a facility with a turbine with molten sodium flowing through it at 2000 degrees and twice the speed of sound "what kind of bad sci-fi book am I in?" sodium-cooled reactors don't use sodium as a working fluid (which is insane), but as a coolant and heat transfer medium. from what I can gather sodium velocities are on the order of 10 m/s.
