0:00:05 > 0:00:06Welcome to Technobytes!
0:00:06 > 0:00:08Not quite as long as your normal Technobabble
0:00:08 > 0:00:10but just as tech-tastic!
0:00:10 > 0:00:12So, without further ado, let's check out
0:00:12 > 0:00:15the randomly named tech app to get out first tech teaser!
0:00:15 > 0:00:19Vlogster, how will we generate energy in the future?
0:00:19 > 0:00:23Oh, good work, Noah! That's a great question. So...
0:00:23 > 0:00:25Who shall I ask to check this one out?
0:00:25 > 0:00:30Eeny, meeny, miny, moe... my mate Marcus has to go!
0:00:32 > 0:00:34MARCUS SNORES
0:00:35 > 0:00:37Oh, Marcus?
0:00:37 > 0:00:40Marcy-warky?
0:00:42 > 0:00:44Hang on, Technobabblers. This should do it.
0:00:44 > 0:00:47- WAKE UP!- What...
0:00:47 > 0:00:49Help me! Mum!
0:00:49 > 0:00:52Ha-ha! Got you! Second time this week as well!
0:00:52 > 0:00:54You should know better, Marcus!
0:00:54 > 0:00:58Oh, Vlogster! I was having a well good dream! Trust you to ruin it.
0:00:58 > 0:01:00What do you want anyways?
0:01:00 > 0:01:02Up and at 'em, Dreamboat.
0:01:02 > 0:01:04We've another of the 'babblers' questions to answer.
0:01:04 > 0:01:06All right, fair enough.
0:01:06 > 0:01:08But do us a favour, put the kettle on.
0:01:08 > 0:01:11- I'm useless unless I've had a little bit of caffeine.- Perfect!
0:01:11 > 0:01:14Because today you're going to be learning about bioenergy
0:01:14 > 0:01:15that comes from waste coffee grounds.
0:01:15 > 0:01:19First stop, a local coffee shop where you can make yourself a cuppa.
0:01:19 > 0:01:20Oh, and while you're at it,
0:01:20 > 0:01:23I'll have a tall, super-skinny, extra wet, soya,
0:01:23 > 0:01:25cappu-mocha-choca-ccino-latte, please. Thanks.
0:01:30 > 0:01:33I'm going to name this the "Marcus Coffee". Let's go!
0:01:35 > 0:01:37Put a bit of pressure on it.
0:01:39 > 0:01:41I washed my hands, don't worry.
0:01:44 > 0:01:46And that is a perfect coffee.
0:01:48 > 0:01:52Delicious, but more importantly, this is what we're left over with!
0:01:52 > 0:01:55Bingo! And that's where your next mission comes in!
0:01:55 > 0:01:57Now that he's had his caffeine fix,
0:01:57 > 0:02:00I'm sending Marcus to a nearby university to meet techy
0:02:00 > 0:02:04Techspert Arthur Kay, who is one of the brains behind bio-bean,
0:02:04 > 0:02:07they make energy using coffee.
0:02:07 > 0:02:08Pretty cool, huh?
0:02:08 > 0:02:12This sounds crazy! Energy from coffee! Explain yourself!
0:02:12 > 0:02:13I know, absolutely!
0:02:13 > 0:02:17I mean, coffee is a strange thing to get energy from but it has
0:02:17 > 0:02:21a huge amount of energy contained within the waste coffee grounds.
0:02:21 > 0:02:24OK, so you get used coffee and instead of throwing it away,
0:02:24 > 0:02:27you make diesel and fuel pellets from this?
0:02:27 > 0:02:29Yeah, absolutely.
0:02:29 > 0:02:31So coffee also has a really high oil content
0:02:31 > 0:02:35so the oil like you put in your car, for instance, for powering
0:02:35 > 0:02:38transport systems and then the rest is a little fuel pellet.
0:02:38 > 0:02:39Instead of wood or instead of coal,
0:02:39 > 0:02:43you can use this renewable energy which can then heat your building.
0:02:43 > 0:02:45We're even looking at how it can be used as a jet fuel as well,
0:02:45 > 0:02:48which would be really cool. The first coffee-powered plane.
0:02:48 > 0:02:50I'd love to see how you make this happen.
0:02:50 > 0:02:53Well, what we have here, if you can see the little...
0:02:53 > 0:02:56The top here, there's a tiny little bit of coffee in that there
0:02:56 > 0:02:59and what's happening here is we have a solvent
0:02:59 > 0:03:02which is being warmed up and being passed through the coffee
0:03:02 > 0:03:06and taking the natural oils out from the coffee grounds.
0:03:06 > 0:03:09That process then turns it from, essentially a vegetable oil,
0:03:09 > 0:03:12into a diesel which can then be used in your car engine or your
0:03:12 > 0:03:13bus engine to get you to school.
0:03:13 > 0:03:16How do you think we're going to be making energy
0:03:16 > 0:03:17in about 20 years' time?
0:03:17 > 0:03:20What we're really doing here is, we're turning something
0:03:20 > 0:03:22that's wasted into something that's useful.
0:03:22 > 0:03:24Most of your viewers like a chocolate every now and then
0:03:24 > 0:03:27and chocolate waste can actually be used to turn into these
0:03:27 > 0:03:29fuel pellets and oils as well.
0:03:29 > 0:03:31So that whole process makes this oil here which you
0:03:31 > 0:03:34then turn into the fuel. Check that out, Vlogs.
0:03:34 > 0:03:36Biofuel!
0:03:36 > 0:03:38I don't know about you, Vlogster,
0:03:38 > 0:03:41but after all that talk about coffee, I think I need a...
0:03:41 > 0:03:44Hold that thought, Marcus, because researchers
0:03:44 > 0:03:47at the University of West England or UWE for short,
0:03:47 > 0:03:49have developed a urine-powered battery!
0:03:49 > 0:03:53- Are you serious? - Wee-ly serious! Ha-ha!
0:03:53 > 0:03:56It's all down to tiny microbes that produce electricity when they
0:03:56 > 0:03:58eat organic matter like urine.
0:03:58 > 0:04:01Right now, the battery creates enough electricity to charge
0:04:01 > 0:04:05your mobile phone but could soon power a bathroom shower or light.
0:04:05 > 0:04:08- If it's yellow, let it mellow.- Exactly.
0:04:08 > 0:04:12Now, Scottish scientists plan to harness energy from the sea
0:04:12 > 0:04:15using giant oysters. These buoyant flaps are fixed to the seabed
0:04:15 > 0:04:18but move backwards and forwards in the waves,
0:04:18 > 0:04:21pumping high-pressure water that drives hydroelectric turbines.
0:04:21 > 0:04:23Does it make an electric current?
0:04:23 > 0:04:25You know, ocean? Current?
0:04:25 > 0:04:27Don't go there.
0:04:27 > 0:04:30Now, ever wondered what a bladeless wind turbine looks like?
0:04:30 > 0:04:31Well, this is it.
0:04:31 > 0:04:35Spanish techsperts think this wobbly way to harness wind energy
0:04:35 > 0:04:39- will be smaller, cheaper, and more powerful and silent.- Shh!
0:04:39 > 0:04:42Brilliant, Vlogster, but I'm really bursting, all right?
0:04:44 > 0:04:47Erm, thanks, Marcus. Moving swiftly on...
0:04:47 > 0:04:49Oh! Saved by the bell!
0:04:49 > 0:04:53It's another tech-topic coming in from one of our Technobabblers!
0:04:53 > 0:04:55Will we ever be able to record our dreams?
0:04:55 > 0:04:57Dreamy question, Taya.
0:04:57 > 0:05:00Let me access my archive drive.
0:05:00 > 0:05:03No-one really knows why you humans dream.
0:05:03 > 0:05:05But to be able to record them,
0:05:05 > 0:05:07first you need to know how much data you might be dealing with.
0:05:09 > 0:05:13Scientists think the human brain is made from around a billion neurons.
0:05:13 > 0:05:16Cells that hold and share information,
0:05:16 > 0:05:18a bit like a computer hard drive.
0:05:18 > 0:05:23The average brain can store close to 2.5 petabytes of memory,
0:05:23 > 0:05:27enough to hold 12 million Technobabble episodes.
0:05:27 > 0:05:28All my favourites.
0:05:28 > 0:05:31Here's a word that you might not know...
0:05:33 > 0:05:36An oneironaut is someone who can tell they are dreaming whilst
0:05:36 > 0:05:40they're asleep then take control of their dream.
0:05:40 > 0:05:43This is known as lucid dreaming and a company in America is
0:05:43 > 0:05:46developing a way to help you do it.
0:05:47 > 0:05:50When you go to bed, a special headset detects when you're asleep
0:05:50 > 0:05:52and the device uses sound and light
0:05:52 > 0:05:55to make you aware that you're having a dream.
0:05:55 > 0:05:58The idea is that then, you can take charge of the dream.
0:05:58 > 0:06:00Imagine!
0:06:00 > 0:06:02You could go anywhere, do anything,
0:06:02 > 0:06:04pretend to be someone amazing!
0:06:04 > 0:06:06Like me.
0:06:06 > 0:06:09Recently, scientists in Japan have found
0:06:09 > 0:06:11a way to tell what people are dreaming.
0:06:11 > 0:06:15By hooking you up to a special brain scanning computer,
0:06:15 > 0:06:17then showing you lots of different pictures,
0:06:17 > 0:06:21scientists can map how your brain reacts to each image.
0:06:21 > 0:06:23When you go to sleep,
0:06:23 > 0:06:26the computer compares the dreaming brainwaves to the ones your
0:06:26 > 0:06:29brain made when you were awake and looking at the pictures.
0:06:29 > 0:06:30If the brainwaves match,
0:06:30 > 0:06:34the computer can guess what kind of things you've been dreaming about.
0:06:34 > 0:06:38In tests, it was spot-on over 60% of the time.
0:06:38 > 0:06:41I know what my brain dreams about 100% of the time.
0:06:41 > 0:06:43Cats.
0:06:43 > 0:06:46Cats dancing the Macarena, cats riding a giant space hippo.
0:06:46 > 0:06:48HE YAWNS
0:06:48 > 0:06:52With similar brain mapping techniques, American scientists
0:06:52 > 0:06:56have used computers to create videos of what the brain is seeing.
0:06:56 > 0:06:59The results are basic but technology is advancing
0:06:59 > 0:07:05so fast that in 30 years it may well be possible to record dreams!
0:07:05 > 0:07:09Imagine that! This is the stuff that dreams are made of!
0:07:09 > 0:07:11Literally!
0:07:11 > 0:07:14And just like dreams, all good programmes must come to an end!
0:07:14 > 0:07:15See you next time!
