thanks for watching techwiki for more great videos explaining everything tech

00:00:03.919 --> 00:00:10.080
click the subscribe button then enable notifications with the bell icon so you

00:00:07.759 --> 00:00:16.400
won't miss any future videos do you have any idea how much power the

00:00:12.400 --> 00:00:19.760
sun sends out into space it's over 380

00:00:16.400 --> 00:00:23.279
yada watts nearly the equivalent of 92

00:00:19.760 --> 00:00:24.880
billion megatons of tnt every second i

00:00:23.279 --> 00:00:29.519
mean just think about how many hot pockets that can microwave but seriously

00:00:27.279 --> 00:00:33.040
though only a tiny fraction of this power actually reaches the earth and

00:00:31.599 --> 00:00:37.760
while this is a good thing in some respects i mean we'd all be vaporized if

00:00:35.600 --> 00:00:41.600
that much energy hit us all at once the sun's energy is responsible in one

00:00:39.840 --> 00:00:45.600
way or another for basically everything on earth so wouldn't it be cool if we

00:00:43.600 --> 00:00:50.719
could harness all that potential well probably but this is basically the

00:00:48.079 --> 00:00:54.320
definition of easier said than done i mean the best we've come up with here

00:00:52.640 --> 00:00:58.239
at techwiki is maybe covering the australian outback and solar panels but

00:00:56.640 --> 00:01:03.359
another idea that's been kicked around quite a bit is the dyson sphere

00:01:00.960 --> 00:01:07.920
and no i'm not talking about the ball shape thing on an overpriced vacuum

00:01:05.280 --> 00:01:11.680
cleaner a dyson sphere is a shell source built around a star like the sun to

00:01:09.840 --> 00:01:15.680
capture its energy output so it can be used later for just about anything and

00:01:13.920 --> 00:01:19.439
if you're sitting there thinking nope enough Techquickie for me today because

00:01:17.280 --> 00:01:23.119
this is clearly science fiction i can't really say i blame you because

00:01:21.759 --> 00:01:27.200
it is not only is there probably not even

00:01:24.960 --> 00:01:32.320
enough matter in our entire solar system to surround the sun with a big eggshell

00:01:30.080 --> 00:01:35.920
thing but because of the way gravity works when the sphere surrounds an

00:01:33.920 --> 00:01:40.960
object there wouldn't be anything to keep it from bumping into the sun which

00:01:38.240 --> 00:01:45.520
would be a galactically awful disaster for what i hope for obvious reasons

00:01:43.280 --> 00:01:49.360
but other dyson-esque solutions could help us solve our resource crisis one

00:01:47.280 --> 00:01:52.799
day and make everything from more powerful computing to paying just a

00:01:51.119 --> 00:01:56.960
nickel on your power bill every year possible in the future now one idea is

00:01:55.200 --> 00:02:00.399
to put a bunch of energy collectors into orbit around the sun forming a dyson

00:01:59.520 --> 00:02:06.000
ring really not all that dissimilar to how we currently have tons of man-made

00:02:03.759 --> 00:02:10.800
satellites orbiting the earth now these dyson satellites would be fitted with

00:02:08.399 --> 00:02:15.440
large energy collectors similar to solar panels now obviously we've had visible

00:02:13.680 --> 00:02:20.480
light solar power for quite some time now but recent scientific development

00:02:18.080 --> 00:02:25.360
has produced infrared collectors and since over 90 of the sun's emitted

00:02:23.200 --> 00:02:28.800
energy is in the form of either visible or infrared light it isn't absurd to

00:02:27.680 --> 00:02:32.879
think we could have collection technology one day efficient enough to

00:02:30.800 --> 00:02:36.640
grab huge amounts of it other proposals call for building

00:02:34.560 --> 00:02:42.480
multiple dyson rings around the sun to form a cage or a swarm of sorts or even

00:02:40.000 --> 00:02:47.040
using structures called solar sails that are so thin and reflective that they're

00:02:44.640 --> 00:02:51.519
actually pushed by the sun's radiation but also pulled inward by the sun's

00:02:49.040 --> 00:02:56.560
gravity at the same time rendering them stable solar cells have actually already

00:02:54.160 --> 00:03:01.200
been deployed for other applications but of course while all of this is at least

00:02:59.120 --> 00:03:05.440
technically feasible unlike the hollow sphere we discussed earlier there are

00:03:03.120 --> 00:03:09.360
still large obstacles to overcome ignoring the challenges of getting all

00:03:07.200 --> 00:03:13.920
the energy back to earth and everything from tethers and space elevators with

00:03:11.200 --> 00:03:17.440
giant wires to beaming concentrated sunlight directly back to the earth's

00:03:15.599 --> 00:03:21.599
surface and hoping it doesn't turn into a giant death ray has been proposed

00:03:20.080 --> 00:03:27.280
actually collecting the construction materials is also a massive undertaking

00:03:24.640 --> 00:03:31.440
one popular idea involves sending robots to mercury to mine useful raw materials

00:03:30.000 --> 00:03:35.920
like iron that could be used to manufacture energy collectors which

00:03:33.599 --> 00:03:39.920
would in turn provide more energy to expand the dyson structure further

00:03:38.159 --> 00:03:43.519
now something like this would obviously still take quite a bit of time to

00:03:41.280 --> 00:03:47.599
accomplish but the hope is that as more and more dyson collectors were built

00:03:45.200 --> 00:03:50.560
production can ramp up exponentially or at least that's what we would plan to

00:03:48.879 --> 00:03:53.840
tell the emperor if he shows up displeased with our current lack of

00:03:52.480 --> 00:03:57.519
progress and speaking of a lack of progress are

00:03:55.680 --> 00:04:01.920
you tired of your internet connection not progressing through the locations

00:04:00.080 --> 00:04:06.480
you want that was a terrible segue but anyway tunnelbear vpn it lets you tunnel

00:04:04.799 --> 00:04:10.239
to 20 different countries allowing you to browse the internet and use online

00:04:08.319 --> 00:04:15.599
services as if you're in a different country they have easy to use apps for

00:04:12.400 --> 00:04:17.600
iOS Android pc and mac and also a chrome

00:04:15.599 --> 00:04:21.919
extension just choose a country in the app turn tunnelbear on and watch as your

00:04:19.919 --> 00:04:26.080
bear tunnels your internet connection to your new location so when you turn

00:04:23.520 --> 00:04:30.800
tunnelbear on two things happen first your connection gets encrypted with aes

00:04:28.440 --> 00:04:34.960
256-bit encryption second your public ip address gets

00:04:32.880 --> 00:04:38.800
switched so you can show up as if you're in a different country tunnelbear lets

00:04:36.720 --> 00:04:42.320
you bypass all the annoying details that typically come with using a vpn for

00:04:40.479 --> 00:04:46.880
personal use there's no need to mess around with port configurations dns or

00:04:44.960 --> 00:04:50.800
any other router settings tunnelbear handles all of that in the background

00:04:48.960 --> 00:04:55.759
they also have a top rated privacy policy and do not log user activity and

00:04:53.759 --> 00:05:00.880
right now you can try out tunnelbear vpn with 500 megabytes of free data with no

00:04:58.240 --> 00:05:04.880
credit card required tunnelbear.com Linus alright guys thanks for watching

00:05:03.040 --> 00:05:08.160
techwiki like this video if you liked it dislike it if you didn't leave a comment

00:05:06.720 --> 00:05:14.880
with your ideas for future videos and let us know if you'd like to see more of these sort of speculative futurology

00:05:12.560 --> 00:05:18.720
future tech kinds of videos or maybe if you want to say

00:05:16.160 --> 00:05:22.560
hey stick to things that aren't dyson rings that we actually can use right now

00:05:21.039 --> 00:05:27.400
then let me know that too and don't forget to check out our other channels and to hit subscribe
