    Even if it were actually doable, this a dumbass idea. It doesn’t take a genius to recognize that night/darkness are necessary for life and that we already have enough environmental problems related to artificial light pollution.

    “By precisely reflecting sunlight that is endlessly available in space to specific targets on the ground, we can create a world where sunlight powers solar farms for longer than just daytime, and in doing this, commoditize sunlight.”

    I was actually thinking 🤔…hmm this would be the best way to tell some other civilization that we live in this planetary system…get a mirror big enough to point a beam out of its normal trajectory in some sort of non random fashion. Basically smoke signals using a mirror.

      I think this would take way to long to travel somewhere where things acutally live the light will probably only reach them long after humanity is gone.

      Humans on Earth have been transmitting radio waves into space for over a century now through various means: television broadcasts, radio communications, and radar signals.

      A laser would work better. Over vast distances, a giant mirror would eventually scatter the light, not to mention would be super inaccurate.

      Speaking of inaccurate, even if we could shine a mirror or a laser, it could be millions of years until that light reaches any other civilization, then they would have to travel millions of lightyears to reach the point of origin of the “smoke signal”.

      I say “point of origin” and not “Earth”, because our galaxy would have also travelled far from the spot we were in when we fired our laser. The Milky Way travels at over 2 million km/h, so even in a measly million years, that puts us over 2 trillion km from where we started. (see edit)

      You can probably see where this is going.

      I’m of the mind that we are undoubtedly not alone in the universe - the sheer scale and endlessness of it tells us that there are an infinite number of possibilities. There most likely are other worlds that formed and evolved in the exact same manner as ours, maybe even under conditions so perfect as to cause them to follow the exact same path as us.

      Though the unfortunate truth is, we probably will never encounter another species. There could be an infinite number of ourselves, but we are forever separated by the ever expanding breadth of space and time.

      EDIT:

      My math was totally wrong, just realized that I was basing my estimates on how far our galaxy travels in an hour, not a year. The distance we travel in a million years would be closer to seventeen quadrillion five hundred twenty trillion kilometres.

        To be fair if they’re able to locate the point of origin they’re probably able to calculate the time it took to get there as well as the current position of our galaxy.

    It’s like that episode of futurama - the mirror wernstrom put in space to reflect sunlight, which gets tapped by a little space rock, and tilts into a solar powered death beam

    I watched a video yesterday about the laser range finder on a tank. The interesting thing is that at long enough ranges, the laser expands into a cone that may be bigger than the target and give inaccurate readings.

    Anyway, I look forward to this totally real and feasible technology.

      You just need perfectly rigid solar mirror technology that you can store in a rocket while being launched.

      Exactly, a laser pointer, while casting a millimeter-sized dot of light at short distances, its light easily gets meter-sized when they reach flight cruise heights, shining airplane’s cabins and interfering with the pilot’s vision. However, as by inverse square law, the power is distributed across the beam.

        I can’t tell if you’re being sarcastic or not, but it’s unfamothably stupid.

        Think, for a second: we already have way too much energy in the system, with too much heat that can’t leave easily. You really want to add to that? REALLY?

        Because that’s painfully fucking dumb.

        I just feel like we at least can, in theory, keep the shit we do on/to earth under control.

        Space is a different world entirely and not only do we not know what effects our shitty pollution projects have out there, we don’t even really care about it as far as I can tell.

          We aren’t even doing it NOW though… Not even close.

          Space will become so littered with high speed debris that within our lifetime it will be no longer safe to launch.

    I don’t even want to imagine the environmental studies and hurdles they’ll have to jump through to artificially alter an areas day/night cycle. There’s a laundry list of environmental concerns that I’m sure any homeowner or eco-activist worth their salt would jump on. Not to mention glare and impacts to air traffic, on and on.

    Would make my solar panels pretty darn effective though. Would probably be great for SAD in winter too. Clever idea. Not sure I can get behind it though.

      Oh Mr X guy, so you want to fly a Teslas into space? Are there environmental impacts? Oh. Yes, one more million. Okay looks like you’ve covered all the possible impacts, you have our go for launch!

        Sending a rocket on a ridiculously stupid task with no useful purpose is not even remotely close to having the same negative impact as this has the potential to. It’s so far apart that it is honestly quite stupid to even attempt to compare them.

            Honestly if X guy could please hurry up and buy this company.

            I need them to go bankrupt or have become illegal before they send some actual junk into space. And if they do send something it needs to have stupid decisions by a higher up so it cant actually remain up there and ruin the nights further.

    How will launching mirrors of the size of your entire farm (if not hundreds times larger) for extra 30 min of sunset ever be more cost-effective than simply adding a small percentage of extra PV panels

    This is this year’s single biggest understatement

    Might be fun for novelty on a concert venue or ball game, but I can’t imagine it’d be economical for solar farms.
