won't miss any future videos do you have any idea how much power the
sun sends out into space it's over 380
yada watts nearly the equivalent of 92
billion megatons of tnt every second i
mean just think about how many hot pockets that can microwave but seriously
though only a tiny fraction of this power actually reaches the earth and
while this is a good thing in some respects i mean we'd all be vaporized if
that much energy hit us all at once the sun's energy is responsible in one
way or another for basically everything on earth so wouldn't it be cool if we
could harness all that potential well probably but this is basically the
definition of easier said than done i mean the best we've come up with here
at techwiki is maybe covering the australian outback and solar panels but
another idea that's been kicked around quite a bit is the dyson sphere
and no i'm not talking about the ball shape thing on an overpriced vacuum
cleaner a dyson sphere is a shell source built around a star like the sun to
capture its energy output so it can be used later for just about anything and
if you're sitting there thinking nope enough Techquickie for me today because
this is clearly science fiction i can't really say i blame you because
it is not only is there probably not even
enough matter in our entire solar system to surround the sun with a big eggshell
thing but because of the way gravity works when the sphere surrounds an
object there wouldn't be anything to keep it from bumping into the sun which
would be a galactically awful disaster for what i hope for obvious reasons
but other dyson-esque solutions could help us solve our resource crisis one
day and make everything from more powerful computing to paying just a
nickel on your power bill every year possible in the future now one idea is
to put a bunch of energy collectors into orbit around the sun forming a dyson
ring really not all that dissimilar to how we currently have tons of man-made
satellites orbiting the earth now these dyson satellites would be fitted with
large energy collectors similar to solar panels now obviously we've had visible
light solar power for quite some time now but recent scientific development
has produced infrared collectors and since over 90 of the sun's emitted
energy is in the form of either visible or infrared light it isn't absurd to
think we could have collection technology one day efficient enough to
grab huge amounts of it other proposals call for building
multiple dyson rings around the sun to form a cage or a swarm of sorts or even
using structures called solar sails that are so thin and reflective that they're
actually pushed by the sun's radiation but also pulled inward by the sun's
gravity at the same time rendering them stable solar cells have actually already
been deployed for other applications but of course while all of this is at least
technically feasible unlike the hollow sphere we discussed earlier there are
still large obstacles to overcome ignoring the challenges of getting all
the energy back to earth and everything from tethers and space elevators with
giant wires to beaming concentrated sunlight directly back to the earth's
surface and hoping it doesn't turn into a giant death ray has been proposed
actually collecting the construction materials is also a massive undertaking
one popular idea involves sending robots to mercury to mine useful raw materials
like iron that could be used to manufacture energy collectors which
would in turn provide more energy to expand the dyson structure further
now something like this would obviously still take quite a bit of time to
accomplish but the hope is that as more and more dyson collectors were built
production can ramp up exponentially or at least that's what we would plan to
tell the emperor if he shows up displeased with our current lack of
progress and speaking of a lack of progress are
you tired of your internet connection not progressing through the locations
you want that was a terrible segue but anyway tunnelbear vpn it lets you tunnel
to 20 different countries allowing you to browse the internet and use online
services as if you're in a different country they have easy to use apps for
iOS Android pc and mac and also a chrome
extension just choose a country in the app turn tunnelbear on and watch as your
bear tunnels your internet connection to your new location so when you turn
tunnelbear on two things happen first your connection gets encrypted with aes
256-bit encryption second your public ip address gets
switched so you can show up as if you're in a different country tunnelbear lets
you bypass all the annoying details that typically come with using a vpn for
personal use there's no need to mess around with port configurations dns or
any other router settings tunnelbear handles all of that in the background
they also have a top rated privacy policy and do not log user activity and
right now you can try out tunnelbear vpn with 500 megabytes of free data with no
credit card required tunnelbear.com Linus alright guys thanks for watching
techwiki like this video if you liked it dislike it if you didn't leave a comment
with your ideas for future videos and let us know if you'd like to see more of these sort of speculative futurology
future tech kinds of videos or maybe if you want to say
hey stick to things that aren't dyson rings that we actually can use right now
then let me know that too and don't forget to check out our other channels and to hit subscribe
