  • Why not use rocks instead of water? The gravitational energy would be extracted with gears instead of turbines. The rocks never wear out, which is one plus, and lots of rock was produced digging the tunnel and power chambers.

  • Is it a good interceptor ? No, it is crap Is it a good dog fighter ? No , it is crap Is it a good bomber ? Good joke Is it stealthy ? Not since 1940 Is it a good scam ? The best.

  • Narrator: *explains how the ISS generates oxygen @ **8:22* Me not understanding any of it: "I like your funny words science man"

  • Excellent video. They're amazing! So grateful to have lived to witness NASA absolutely nail it and begin a new era. 🙏🗽🇺🇸

  • Can we transfer the electricity by using electromagnetic waves instead of cables? Same as 5G technology?

  • selists.info/less/video/otqed7amkKSWlqQ.html

  • @Real Engineering Just to be accurate : the Russians also landed on the moon, actually, they did it earlier than the US.... and they use metric system.

  • mars rover operates at 110w power for a whole rover and all the instrument... here earth people using 110 in a single bulb.. 😐😐😐

  • Metric is better than imperial. However, Fahrenheit is objectively better than Celsius.

  • Why don’t we use simply the ground earth to store the electricity? Sands or dirts

  • Can we charge the solar cells at night?

  • People fail to realize that the big boy wind turbines have a production life of 25 years max then they are rust buckets that have to be demolished because it's too dangerous to disassemble them. The massive composite blades have no half life -they are mammoth fiberglass hulks that fill ENTIRE landfills FOREVER as they do not degrade. There is no such thing as recycling the blades as they are falling apart pieces of junk by the end of their service life. (By the the way, a nuclear plant service life is 50 to 75 years) And we haven't talked about the displaced animals and hundreds of thousands of birds of prey killed every year by wind turbines. If people want green energy then they should back zero emission, safe nuclear that output hundreds of times MORE power (one reactor = 1,520 big wind turbines) on a footprint that is a 100 times less. Remember, this gleaming white monstrosities become massive, broken dangerous rust buckets in 25 year or less -search Germany and wind turbines. The Germans invested first and very heavily in wind and now they are secretly firing up more and more coal fired plants as their turbine are literally falling out of the sky as massive pieces of junk. Research what these turbines and blades look like after 10 or twenty years of service -they are no longer gleaming white statues but rusty and dangerous hulks that literally pose a danger to anything beneath them. The reason they are building these inefficient mammoths is NOT because they are great value for the energy dollar BECAUSE they are built with government subsidies. People and governments erroneously think these initially gleaming white things will last forever -THEY DON'T. The demolishing of these monsters will offset any fraction of use that they had. If they lasted one hundred or two hundred years and didn't wipe out millions of birds all over the world then they might be viable, but they don't. Smaller wind turbines are useful for small remote sites or villages NOT for producing base electricity for the grid.

  • Can we use the 5G waves converting it to electricity?

  • No, Mr Real Engineer, it does not remain "...a point of contention whether analogue formats such as vinyl are actually superior to their modern day digital counterparts." There has never been any real debate about this, at least not among people who had any idea what they were talking about. Vinyl recordings of virtually all music is undoubtedly superior to digital recordings because the bandwidth is theoretically unlimited on vinyl. The only debate is about whether or not this makes any noticeable difference to our perception of the sound that we hear, and the answer to this is (as Mr Engineer correctly states) 'usually not'. Most music, especially popular music, is not noticeably degraded by being compressed into the bandwidth required by digital formats and I cannot really tell the difference in most cases, but there are some notable exceptions. For example, I have two recordings of Andy Warhol's Velvet Underground with Nico; one on vinyl I bought fifty years ago, and one on a CD I bought ten years ago. Anyone familiar with this album will know that it sounds as if it was recorded in a corrugated tin shack somewhere on the East Side docks of New York (I just made that place up - does it exist?), or in grotty basement night clubs with the expected acoustic qualities: but this is a feature of the music and is part of its appeal... its ambient nature. When it is filtered and cleaned up and compressed into the narrow confines of a digital recording it loses much of the quality that made it unique and that conjured up the smoke-filled drug dens that Lou Reed and Nico inhabited and sang about. There are other examples of music where the digital versions (and especially the very meagre ones sometime provided by digital downloading or streaming services) are noticeably different from the recordings on vinyl, especially live music, and in these cases I would far rather listen to my vinyl versions (on the rare occasions when I am sitting at home in my living room) than turn on my CD player or iPod, even though the latter are far more convenient. These days, like most people, I usually listen to music through my iPod or mobile phone or CD player, or on my computer, because it is easier and allows me to combine music with whatever else I am doing, but I don't kid myself that it is always the same experience as listening to an album, or even a single, spinning on my record deck... in most case it is indistinguishable, but not always.

  • I knew there was something up with the parachute :,)

  • the metric system is for simple minded idiots.

  • At the cost of $1B for 230MW per 6 hour storage facility, Ireland may as well just build a new 4 1000MW reactor nuclear power station to provide enough base load.

  • Cool stuff!!!

  • The microphone has been damaged and does not work anymore

  • I’m sitting here thanking that I thought about this over 30 years ago I was on Martha’s Vineyard on a JetSki pulling into a fishing village there was someone standing on the jetty casting his fishing rod I asked him to stop for just one minute so I use used him as a marker I pulled Right next to him and didn’t move I looked down at my speedometer It said I was moving at 17 miles an hour and I said this is constant in and out 24 seven the power and I was designed these things in my head and never do anything with them we’d walked through stores and my brother would say see that thing there my brother invented that 30 years ago and never did anything with it now if they sell it the ideas in my head alone I’ve seen over 25 things that I designed in my mind and never did a thing with them I have one that I got to get out there because it will save so many lives Anyway day late dollar shot

  • This is just hilarious: “In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade-which is 1 percent of the difference between its freezing point and its boiling point. An amount of hydrogen weighing the same amount has exactly one mole of atoms in it. Whereas in the American system, the answer to ‘How much energy does it take to boil a room-temperature gallon of water?’ is ‘Go fuck yourself,’ because you can’t directly relate any of those quantities.” Wild Thing by Josh Bazell

  • Let me explain the metric system: The base length unit is meter. It is equal to 100 centimeters or 1000 millimeters. 1 kilometer is 1000 meters. The US is about 4500 km wide. 1 meter is around 3 feet. Area and volume are measured in square and cubic versions if the previously named units. When measuring liquid volume, we usually use milliliters (1 cubic cm) and liters (1000 ml). A regular cup of water is around 240 ml. We measure mass in grams, killograms (1000 g) and tons (1000 kg). 1 liter of water has a mass of around 1 kg. It depends on different conditions, like temperature. Average human mass is 62 kg, average elephant mass is around 5 tons. Temperature is measured in degrees Celsius. 0° is the freezing point of water, 100° is its boiling point. Human body temperature is usually around 36.6°C, regular room temperature is around 22°C. We measure force in newtons (1N = the force required to accelerate 1kg to 1 m/s in one second), pressure in pascals (1N per square meter). There are also much more versions of all those units, like milligrams, nanometers, kilotons. Join the metric system. We have logic.

  • There also a binary code in the wheels which is written in the dirt as it moves

  • The macho perfume distally afford because smoke biochemically slap across a absorbing spider. axiomatic, receptive oval

  • writing, because I don't know

  • I use all formats. Without a doubt vinyl is superior. It gives the music depth detail and dimension which digital just can't do. I dont know why that is because in theory digital should be superior but it isn't. Plus, collecting vinyl makes you cherish and love the format. You have to carefully take the record out of the sleeve, dust it, set the needle down, watch it going round, check out the artwork, in general it just makes you really listen to an album the way the artist wanted you to hear it. I have converted so many young people to the cause lately and they are now fanatics.

  • MERS xD

    • I don't get why NASA isn't already prepping a return rocket and pickup rover now as it could be creating the fuel while waiting for the pickup rover return.

  • Why do so many poster haves to use ridiculous hyperbole? Its not insane, its rather quite the opposite. Sane and intelligent. Unlike the title.

  • Cute parachute! Bigger mystery is how NASA has consumed ao many billions of taxpayer money over so many decades for relatively little results. Maybe NASA (aka money pit) can decode that mystery for the public to understand. Should have bases on the moon and Mars by now. Give the job to Elon- He'll get twice as much done in half the time for ¼ the cost.

  • Metric sucks

  • Hogwart 😆

  • "They became upright and taught themselves the use of tools, domesticated other animals, plants and fire, and devised language. The ash of stellar alchemy was now emerging into consciousness. At an ever-accelerating pace, it invented writing, cities, art and science, and sent spaceships to the planets and the stars. These are some of the things that hydrogen atoms do, given fifteen billion years of cosmic evolution." Carl Sagan, Cosmos

  • It wasn't Russia, it was USSR. Big difference, even if you don't believe. Otherwise, cool vid!

  • A duodecimal-based system (like a clock) would be the optimum. Sadly I'm not holding my breath on that one.

  • Led by Britain and America haven't you forgotten Canada. I'm sure they remember it very well indeed. 🏴󠁧󠁢󠁥󠁮󠁧󠁿 🇬🇧

  • This video is horse-shit. It doesn't at all take into account the externalities of mining Lithium or any of the other precious metals that go into batteries and it doesn't take into account the mean-time-before-failure numbers for said batters (lifespans), which is the replacement cost. H2 fuel-cells don't ever have to be replaced, making them much more efficient in the long term. Further, this video doesn't take into account the H2 vs. Gas comparison, which works out incredibly well for H2.

  • The flimsy schedule nomenclaturally push because agreement ultrascructurally wreck round a shallow garage. roasted, rude swing

  • mærz...

  • Well, it was a good shot. Now, back to trying to engineer a way to remove more maple syrup from the maple tree.

  • I as a mechanic I had to use both sae and the metric system in the US I definitely prefer the metric system everything is in 10's and like you said you just move the decimal point so I wish the the US would just change over to it. I am tired of not knowing what wrenches I will need when I crawl under a machine. I end up take both. But I do take offense you saying that we marry our cousins, maybe down in the south east. Lol but my family didn't. Anyhow I am all for the metric system. I don't need to jump on the bandwagon I am already on I am just waiting for the other idiots to get on!

    • @GH1618 You miss the point eventually they all are going to be replace just replace them in metric. It is a hell of a lot easier to work with and or train new mechanics. They have been doing it in the auto industry.

    • If you are in the business of repairing machines, do you really want all the old machines built to SAE spect to be scrapped instead of repaired?

  • Great video

  • Why are engineers wearing suit during development?

  • Sounds like a little bit of fear porn. The planet will do what's going to do regardless what we do. It's not just the planet heating up it's the entire galaxy and no green technology is going to stop that.

  • I'm sure the martian cavemen will pick up on this easily.

  • Aaah Great to see the Men at the NASA control room. I bet that's one of the few places left where actual talents matter and diversity, inclusion and tokenized piece of craps doesn't.

  • Superbe CGIs! Thanks for sharing. I will send you the video of my cat’s landing on Pluto. He encountered a few turbulences - but everything went well. He made a lot of mice friends and he does not want to come back.

  • Unless I'm totally missing it, you seem to ignore the immense energy cost and impact of the lithium cycle (not to mention other metals), from mining/extraction, shipping, processing, shipping, battery construction, shipping, recycling, shipping, environmental waste, for starters.

  • Dumb question, could the efficiency hit of due to heating LMBs be mitigated if they were used in conjunction with nuclear? (which already runs at many hundreds of degrees). So hypothetically, one of the loops in the nuclear power plant passes by the batteries which want the heat. The batteries can then be charged/discharged on-site, the location already has access to transmission lines (so no new power-pole infrastructure needed) and since its hard for nuclear to ramp up in times of need (as their output is consistent, and thus why we have fossil-fuel peaker plants), they could act as an easy way to increase output at a moments notice for the nuclear power provider. If there aren't too many errors in my assumptions (I'm just a guy who likes learning about this stuff on youtube...), seems like a winning partnership.

  • I'm pretty sure digital audio output is sin(x)/x interpolated eliminating the granular/chunkiness argument against digital.

  • If America (and those making videos for America) want to adopt the metric system, they ought to learn how to spell it. Metre. And don't get me started on fibRE (as in optics)................. As an Engineer, brought up on Imperial, - nothing wrong with Imperial, except that the rest of the world is metric. It's like the RoW not speaking English, confusion can be expected. And don't get me started on "American English".................... Now tell me the mnemonic for 299,792,458 - which destroys yer ease of use argument.

    • We in the United States adopted the metric system in 1866, but we are not going to change our spelling of “meter.” “Metre” is a French spelling.

  • I love your videos, but I still can't handle how you pronounce "Maers". 😂

  • 11:11 UFO spotted

  • The insane gullibles believing this crap

  • ABACUS CAE, a French engineering calculation software that is considered the holy grail of CAE softwares, CONTAINS NO UNITS. You have to input parameters with consistent units, and read the outputs knowing the units yourself. So basically if you don't use SI, you are screwed. I think that's the French's way of saying viva la SI, and sticking the finger to English imperial:)
