      @@Me-vz1rl so what I was in college I rented a basement apartment and it had a Natural Gas hybrid fireplace radiator meaning there was a window in a metal box they could show you the flames. There was no exhaust. However so all of the carbon monoxide was going into the room. The homeowners wanted me to just open the window a little bit for oxygen but having oxygen is useless when carbon monoxide bonds to your red blood vessel. So back then Yellow Cab did not have any Priuses and you could ask for an even car more car if you know what I mean. I don't know if that was necessary that day but once I did that to move all my stuff and I was successful but because I had live so far off campus I had to call taxis fairly regularly. Anyway I went to Walgreens and bought an electric radiator. The difference between the two heaters is that the electric radiator would overheat very quickly and I wasn't with it back then enough to be brutal and have a fan blowing on the radiator at least when I wasn't home. This is going to get really good in a minute so please don't give up on the boring comment here he quite yet. so I turn the thermostat all the way up and left it on all month long at which point my landlord's complained about the $70 jump in their electric bill. Remember this is about three times as much power as this light that you're complaining about and the light is only about 50 lumens per watt so there is very little talent in the cost engineering behind this project. The sourcing of farts and overall design is a proof-of-concept level despite the long gestation. Our former well what is it called well always lame past and forever goon talks about smaller windows and no windows. This is a ceiling light for people who live in Condominiums. you need to put your solar panel on your balcony and those panels are about what this led consumes except you don't need all the control circuitry that both LEDs and solar panels normally require but you do need to have a friend match up the solar panel and the LED that you use very precisely because you're going to be doing augmentation. Like a pedal-assist bicycle. you don't need to have the trade speed nearly horizontal. People are very cheered by noon Sun the problem with sleeping late is that by the time you get through out of your shower it's already set. Moving into the basement I increased my lighting bill by 2/3 you might say because previously I had use the single light bulb in the ceiling 2 lamp fixture knowing I would get far more light from a single 300 W filament then to 150 bulbs. as a test engineering price point this is providing 22000 lumens and has a very low CRI after the soapy water LOL. a sunnier fixture is available at Home Depot delivered for well under $200. in fact they raise the price $5 recently. It's very lightweight and durable and if you have like many kitchens have an outlet on the top of the wall by the sink with the cord plugging in and then hanging from a hook in the center of the room above the dining table kind of braided through a metal chain to support a kind of umbrella fixture you're good to go.
      Anyways that's going to give you over 50% more light without any glare so you can be seated around the table working on a card game or using clay with your grandchildren anything at all that you are working on on that table in the center of your kitchen 4 let's be honest less than a penny an hour. that fixture is obsolete. they have light bulbs now that have much higher density so you could put them in a say eight bulb bathroom vanity if you upgraded the wiring to handle the current as those are generally spec that 60 to 100 watts each. Again you were going to save so much money on your heat lamps in like a year!
      So I got through the winter in that basement and even the summer my father visited me for a few days in fact but my living room was more like a dungeon having an unfinished floor Etc. we didn't use carbon monoxide alarms back then but they claim that the gas company inspected the heater and found it hunky dory. you know because the owners of that house where elderly back then it's kind of unbelievable to me to know that they are long dead but anyway they got the revenge when they left for the summer and rented the house out without telling me. Apparently they investigated my defense about how they were likely not running their oil burner anywhere near as much as I kept my window shut all winter instead of open all winter even if the likely radon gas common in basements might end my days down long before I'm their age back then. the oil burner had a pump that made a huge high frequency squeal which is another reason I moved out besides the radon and the cardinal rule about never doing laundry during sleeping hours being broken.
      we make choices in life. it's politically correct to spend tens of thousands of dollars on ground Source heat pump Heating infrastructure just on the demand side hey K within the home instead I'm buying all the cashmere you can possibly enjoy Plus enough of light to grow your own broccoli because watching your broccoli grow as well as the finest cherries not just the Exotic spinach by The Bushel so everybody you know is supplied beats all of the engineering goals of this video.
      Taxpayers by the way that means people using resistance electric heat to chill themselves into hundreds of dollars a month of icy existence forcing evaporation on their skin more than any warmth. 300000 lumens is more like it not under 30000 but tenfold more. that's the way to not get depressed under the covers in the dark. It requires printed materials to read if you're stinking rich and don't have people to play with or work to do with your eyes and helpers.
      Nobody pays quarters per watt for inefficient solid State emitters unless they're more interested in wowing then actually pleasing with the results of the project.
      I had a lot more in the anecdote but my dictation is poor if anybody replies I will provide more buying instructions for the ultimate winter indoor solution Bliss wise.

      We wont be making trips in space long enough for this to be needed I dare say never but at least not anytime in the distant future. We realistically don't have the tech to go far enough away from the sun that you would miss it, in fact the sun in space is quite dangerous as too much direct exposure is deadly as you are getting direct sunlight with no filtering which is not good. Would be great for bunkers, maybe even really helpful to those that can't be exposed to direct sunlight on earth for various conditions.

    2) a “filter” to mimic sky soft box that is a cloudy day

    I’ve actually built this with a 100W LED and a 90cm wide sat-antena:
    Upsides:
    - it really looks like daylight, amazing.
    - relatively cheap
    Downsides:
    - it takes lots of space
    - the cooling fan for the heat sink is loud enough so that it’s annoying and a reminder that the light isn’t sun light (I just ordered an ultra quite fan, let’s see what happens)
    - a 90cm wide antenna will give you an illuminated area of just about 0,6 m2, which is not much, and if you put a squared window in front with the nanoparticles solution, it will cut the corners and make it even smaller.
    The powerful LED, the big SAT antenna and the water cooling really make sense: more light, less noise. But it still has the space consuming problem.
    All in all really cool thing and I don’t regret building it.

      @@TemporalOnline I think the big one would. But it would have it’s limitations f stop/d.o.f wise - and you would only use it to simulate sunshine. Something I’ve done maybe half a dozen times in 20 years... So good for that particular effect if the videos any indication but it’s not something most people are going to use very often. I guess you have to way that up...
      To achieve a similar effect I lit the white studio walls and ceiling with gelled light to work as my big blue sky reflector for the colder shadows, and use a snooted head with a grid spot, at high ceiling level, to simulate the sun. Once you get the balance of brightness and colour right, that worked well (although long shadows lost focus a little too quickly). I used that technique to shoot a family and photoshop them into a field with dad’s arm around a cow - yes, a milk campaign. : ) The designer was sceptical at first, but it worked well in the end. But I really had to fine tune the lighting to match the previously shot cow. The sweet spot was surprisingly small. Adjustments were down to tenths of a stop before it looked right.

      You should be able to get a upside-down umbrella 30000 lumens lightweight fixture ready to plug in to the regular outlet all set up totally complete on clearance for 50 bucks. If you must have it by there for tomorrow just spend about $155 which is the now 2 or 3 year old full price for the down 30000 Lumen from any hook. You can even hang it from a clothesline that you run from one side of the ceiling to the other by using shower curtain rods against the wall to securely attached to the ends of the clozeline to the ceiling. If you want special light colors you can put whatever films you want under that lamp. This isn't complicated. When the light light is not bright from outside day or night you don't need to pump the heat out of your house you need to convert the electrons to photons and depression cares about a glare but not about what Toshiba and other scammers Shout. You have to trust me on this.
      For under $100 at Home Depot I think they have a 300 watt regular light bulb socket bulb. I tested that bulb in the Home Depot using one of their common table lamps as a fixture. Yeah that bulb was 170 Watts but the equivalent of a 500w discharge high intensity plasma output it's speciously claimed.
      Again I'm talking about stuff that's been available at retail for years. inside the box is a mogol lamp adapter since that's what people normally have on their ceiling LOL but the bulb itself is as I proved two employees that were just in shock despite technically knowing the facts it would work and work so well the one dude that help me out almost slapped me when I said you can put it in a 3 lamp table fixture LOL or even as I mentioned 8 bulb vanity every city in the world has in their dumpster at most thrift stores.
      Before most of the people on the planet were born the Germans were talking about the theory of s a d depression being relieved by photons. it's what you do in the light that cures you because being tortured at the light will not give you as much joy even if brighter. I normally mock government Regulators regarding lighting but this project seeking the highest wattage old school projector bulb available ineptly redeems the shift to sourcing based upon lumens instead of wattage. we cannot detect collimated light. I have that denim Recycled Fiber shipping insulation because it's wrapped in mylar on the floor by my divided light door and there is a nearly privacy but transparent curtain which has Sunshine shining out the gap on the bottom and that the d call mates the Sunday meme sunlight gloriously so it bounces off my popcorn stucco ceiling in the center of my long Studio which is quite large by the way just a few square inches of sunlight bounced off marlar kicks ass but that's because I'm not in Germany or even Michigan or Illinois Etc.
      that's what copper is good for you can very inexpensively connect solar panels to diodes and for those who want actually engineered equipment and our spunky enough to spend a fortune on even used appliances please go to B&H they have an excellent app if you're not in New York City. with what you save on your heating bill pick up a pair of rad binoculars but always check their you Jim and Tori of used items in whatever category first! it's their used inventory that has me endorse them and their app, don't hire an interior in director decorator save the fortune and spend real money on quality Hollywood grade if absolutely by Hollywood fetishistic nonsense awesome unbelievably awesome works of art no less when it comes to lighting. there is one more thing to say. Going to the landfill as we speak and for several years now are billions of dollars of Mercury and sodium vapor discharge systems. they have been on Public Surplus for a dollar each when still brand new.
      Blame RUclips. Walter Cronkite is a school but without any news organizations to hire the graduates lives are in fact being lost as entire medical school libraries are hauled off to landfills despite India being willing to fly them overnight to wear the price of light does not involve nonsense at night

      @Asdayasman 4 года назад +77

      @@mr.blackhawk142 Cancer is a fault in DNA in such a way that the DNA creates cells that lack the instruction to kill themselves when they get too old and faulty. These immortal cells expectedly break over time, but instead of dying and being reabsorbed into the host body, they selfishly live on and do nothing useful, only creating more faulty copies which waste resources.
      One of the ways in which the DNA can come to lack this instruction is by being modified by an external energy source. Most forms of energy which we come into contact with on a day to day basis - sound, visible light, ambient temperature, etc., are either too low energy, or don't penetrate the body's defences enough to cause any damage to living cells.
      The exceptions are things like natural sunlight, which contains a good amount of ultraviolet light, which _does_ penetrate our epidermis, the outer layer of skin, and affect the living layers. Evidence of this is stuff like sun tans, and skin cancer. This is why you don't get a sun tan from regular room lighting - it contains no UV wavelengths.
      Naturally, if the sun was an instant cancer death ray, humans would have died out as soon as we shed our fur, but we can actually tolerate quite a bit of it. Some of us who evolved in sunnier places can tolerate a lot more, evidenced by darker skin. Like you said, it's not harmful if we don't overdo it.
      Sunscreen is literally just "black" UV paint. In the same way that black paint absorbs most visible light, reflecting very little, and appearing black, sunscreen contains chemicals which absorb most UV light, not allowing it to penetrate your epidermis as much, essentially causing each second in sunlight to count for less, extending the time for which you can safely be exposed. When looking at someone wearing sunscreen with a camera that can pick up UV light, it looks like they're wearing black or dark brown bodypaint. I believe Veritaseum has a video on this. Unsurprisingly, this mimics the natural protection the aforementioned people who evolved in sunnier places have.
      I don't know where you got this idea that "sunscreen causes cancer", but it's completely false. If the cancer threat vector is prolonged sunlight exposure, sunscreen _prevents_ cancer.

    OK Here is an extra challenge for you! Instead of the Blue sky, how can we mimic the more colourful tones of a sunset? Because many times film makers need to shoot a scene when the sun is going down. And either the weather is not quite right. Or otherwise (regardless of that) there is only a very limited amount of shooting time available during that time of the day. Or they are not coordinated or ready to be setup in time to catch the sunset. Can you solve this problem and create an authentic looking sunset? It is perhaps the most beautiful and best time of the entire day.

      For many, the circadian cycle is already disastrously impacted by improper use of light emitting devices a.k.a. monitors.
      Generalyze this statement to technology at large and you've got the source of all our global problems : we use technology improperly.
      You feel I am exagerating? Well you are blinded by ignorance and/or egocentric priorities. Look at technologies that spread fast and wide. They all created large scale problems. Not cause they are themselves a problem, but because we use our knowledge and inventions like donkeys. Our moral and social evolution are eons behind our scientific and technical capabilities. We mostly don't deserve what we have.
      We do not ALL need such a lamp in our home. That's a techno-enthusiastic donkey point of view. We do ALL need sunlight. We could extract, transform, fabricate, assemble, transport and power millions of such lights. At the cost of so much resources. OR. We could instead make a society where homes, schedules etc. offer access to sunlight.
      What is efficiency when we are an entire race of consumers? Shortterm satisfaction of personnal desires or longterm satisfaction of collective needs?

      but anyway, personally i would still like to have this device, bc i live in a climate where we get maybe 5 hours of daylight in winter days and it's not even proper direct sunlight, it's a pale gray glow from getting filtered through a permanent gapless blanket of clouds. i think most of the people who would want a device like this are those like me, who live so far north that no amount of housing or scheduling will summon sunlight that isn't there. i wonder what impacts on our collective mental health this device could have.

Very convincing and likeable character, with great quality, smooth cinematic type content, so no surprise being influencial!
      A "kit" like this would be well over $1000+ for a decent sized window using a large fresnel lens. You'd be paying for the "idea". So more like $2000-3000+! (cheap end). LED skylights can cost several hundreds which is essentially a $30 LED panel LOL...... (with a few tweaks)
      For this build, if you source all components yourself, around $1000. If made by scrap, you can save hundreds on the lens Itself!
      Diy is the way to go! 👍

      it does matter as the future astronauts will need to maintain their circadian rhythm, as well as make chores and have a way to know when to wake up and stuff like that, maybe the project would have to be applied to the whole facility as a way to mimic day cycles, mental health in space could be highly degraded without routines and days, the thing that they would want to avoid is the feeling of being locked up in a building.

    We have four hours of light midwinter here so thank you! (We also have a midnight sun in summer which is lovely.) I’ve never felt light deprived though and love my aero gardens which help. Good lighting really helps and meditation chases any blues away so it’s never affected me. I’m an artist so your design really impresses me and it would be incredible just for painting. How wonderful if would be if you could find a way to develop and market this and do it in a way everyone could easily and safely use anywhere! Maybe even in space. ☀️

    If you look for nanoparticles, I suggest you looking into Ludox, a colloidal suspension of silica nanoparticles in water. You can also buy polystyrene nanoparticles almost everywhere: 30-50nm should be the optimal size in water, if you want to go for the highest realism; they can be quite expensive, but 10ml should be enough for your window. If you are able to get your hand on aluminium nanoparticles, you can also embed them in a resin matrix. Nanografi.com looks like a good place to start searching.
