people are happier, work harder and pull together more when they feel they're part of something bigger, doing something grand.
the race to the moon was just that. Something remarkable.
A generation of kids grew up wanting to be astronauts or to build rockets: something of huge value when so many young people don't really know what they want to do or be.
a bigger telescope or a some slightly better motors might be of more scientific value but they only make a rare few dream of being anything or doing anything.
It wasn't just the steel but also some methods of treating the steel which became useless and were lost after the mine went dry. there could have been other mines with the same impurities which nobody ever realised were there.
"Like I said, it depends on the application you have for it. Not everything can be made of diamonds, rubies and single crystal superalloys."
in real terms the cost of making a turbine blade (tens of thousands) or a sword in a similar manner is probably lower than the cost would have been to make a really good sword back in the day. steel was insanely valuable and blacksmithing was slow. really really slow.
what have diamonds to do with anything? single crystal superalloys aren't made from some rare crystal. they're items made of a single metal crystal grown without flaws or weak points.
from your comments I'm guessing you make your money through IP in some way but not at the coal face actually creating stuff, rather off to the side leeching money away as some sort of manager, lawyer or similar. Copyright, trademark and patent law aren't all one homogenous mass, they've very seperate covering very seperate things and what can be good in one industry can be toxic in another: like patents applied to software. IP law isn't whatever you want it to be or whatever would let you get a bigger house.
No he damn well shouldn't be able to any more than he should be if you reference a book which blatantly plagarises others.
sure it's good to capture that kind of stuff when possible but don't worry too much. almost nothing is ever lost forever. If master craftsmen 1000 years ago could figure it out then master craftsmen today can figure it out again.
there's a lot of mythology around many such things. having a few pints with an old master blacksmith can be interesting. there's a number of master blacksmiths who spent years figuring out how to make blades which were almost indistinguishable from wootz but the point to keep in mind is that the challenge was to figure out how they did it with tech of old. not how to make superior metal.
The best blades ever produced in ancient times wouldn't hold a candle to the best that could be made now by the best engineers now. If you made a blade using single crystal superalloys like they use in jet engine turbine blades it would make a mockery of the best of the best in ancient times
Even if we lose the skills there's lots of bright people who'll either figure it out or figure out a better solution.
unless their presence allows someone to save energy in some other way.
if the map in your glasses mean you don't take a wrong turn and end up having to drive 15 minutes back then they've just saved lots of energy.
if the cell phone you carry allows you to call the delivery guy and let him know the order has been cancelled before he gets somewhere with a landline then you've just saved the energy cost of moving a truck miles.
if that computer system in the warehouse tracks items better than a human operator then you've just saved the energy that would have been wasted when the paperwork for a pallet full of stock is lost and it goes bad before anyone notices.
that video link and high bandwidth connection may take a bit of energy but if it means one engineer doesn't need to catch a plane out to fix a problem in a factory somewhere then it's energy cost gets paid back a hundred times over.
He may have gone a bit far with saying it should be done in a different state (due to time constraints) but improper blinding is just bad science.
if someone it testing something and believes and it's not properly blinded then their results will tend to reflect their beliefs.
nobody in the lab should ever know that sample 1234ABC43 is a sample from "the jones case". They get sample 1234ABC43. they give the results for 1234ABC43.
failing to do this would be flawed science.
They may not mean to, they may think they're doing everything perfectly but without proper blinding they almost certainly aren't.
no, I use small words because you misuse terms as if you heard them in a meeting one time and have no idea what they mean.
I can only assume that you're the child of someone important who got you a cushy job where you got to feel important while the people around you roll their eyes and try to get on with the real work.
"In the UK, where light very rarely ever shines full, and overall, most areas on the moon would have higher yearly solar insolation, even with two week long nights! There's no atmosphere to contend with, and the moon is closer to the sun roughly half of the year, which means more sunlight and more power."
lets put this in small words. really small words since you seem to be having trouble with this concept. it's not the total power input which matters. it matters how much you can store. you could have infinite energy thrown at you but if you can't store it it's useless.
yearly solar insolation is useless to you if you need power half way through the 2 weeks of night.
36Wh per hour. *50 *336 *number of people on the base.
604800 watt hours to keep one person with food and oxygen for 2 weeks.
lets say we use the best lithium. 200 watt hours per kilogram
that's over 3 tons of batteries.
with ultracapacitors that would be 17 tons BTW.
per person. so lets say we have only 10 people on the moon. that's 60 tons of batteries before you do anything else. before you account for any other power they'd need for that 2 weeks.
Utilizing which battery chemistry? Might want to rethink that statement, pal. Plenty of battery chemistries that charge efficiently and do not lose power. (Oh, like ULTRACAPACITORS.)
Right now there are expensive cutting edge ultracapacitors that store something like 35 watt-hours per kilogram
You're the expert.
from TFA: "to grow enough food for one person we need 50 square meters of agriculture to provide both food and oxygen life to support one human"
so. with LED's how many watts of electricity do we need to grow 1 square meter of plants for one hour?
now multiply that by 50. now multiply that by the number of people on the base. now multiply that by 336. then you have now many watts you need to be able to store. "ULTRACAPACITORS" because "ULTRACAPACITORS" have a crappy energy density vs regular batteries. you'd be thick to try to store your power in unltracapatitors. Lithium-ion has an energy density 4 times that of "ULTRACAPACITORS"
"Also, it has plenty to do with DC, since your solution above would propose converting from DC to AC, then back to DC "
you don't seem to understand batteries. no they do not need alternating current. you can charge with direct current and draw out direct current. the losses are in the form of heat when you do either.
"Yet my research facility operates on solar and batteries just fine"
on earth. *on earth*. not on the moon with 2 week long nights.
by chance did you have a relative who got you your current job, one who told you that you were very very special.
"Yet we just had a BBC special regarding our technology that grows plants utilizing ZERO LIGHT"
they're called mushroom farms. they've been around for a while. they suck at producing oxygen though which would be kinda important.
it's like saying "magnets" when someone asks for a electric motor as if that's an answer.
As pointed out trying to run it off tesla batteries would be supid. you'd need something like 10 tons of batteries per person for the 2 weeks even with LEDs.
"Why not power the LEDs via STRAIGHT DC ONCE IT'S AT THE BATTERY? LEDs *ARE* DC devices, after all."
I hope to god you're just making up your claimed job because if someone like you conned their way in there's no hope for wherever you're working.
when you store power in a battery and then get it out again a few days later you lose about half of what you put in. that has nothing to do with using DC.
Farming may be practical with some other energy source like an RTG but trying to use batteries to store enough power from solar for both farming and *everthing else the astronaughts need for 2 weeks* is pretty braindead.
Synthetic hydrocarbon fuel: same problem as batteries.
Methane (SNG Synthetic natural Gas): ditto
Mechanical storage: not enough free water.
Thermal storage: not practical over 2 weeks.
so no. not really. waving at energy storage systems is not a sollution because you have to store so much and everything has to be shipped up from earth.
I occasionally drop 10 bucks on DwarfFortress. But that's because it's unique, there's nothing out there like it and I'm paying to see it keep getting made.
yes you have to deal with the face that the lunar days are 28 earth days but storage can deal with that.
You say that like it's nothing.
1: you piss away half your energy converting to battery and back again.
2: no it can't. try running an indoor grow house off batteries for a week solid. it's not a trivial task. you don't just need light but also heat.
you wave away massive problems. 2 weeks of darkness kills solar dead unless you want to ship many many many times the weight of a reactor up in the form of batteries.
An innovation can be as small as a neat new way of handling some user interaction which nobody has done before or a heuristic which solves a hard problem but at the same time people from buisness or management backgrounds or courses do set an insanely low bar for what they consider "innovation".
If you were to believe buisness grads then "innovation" includes their "ideas" along the lines of "a website like *only better*" or "that thing which everyone is already doing but which I think is my neat new idea"

a Google search uses just about the same amount of energy that your body burns in ten seconds but if you save a trip to the library or avoid a pitfall in some project as a result it can save a massive amount of energy overall.
