The supply of clean sustainable energy is one of the greatest challenges of our time. Better batteries for electric cars and solar power for homes require advances in new materials and underpinning science. Using 3D glasses, Saiful Islam will show how atomic-scale modelling and structural chemistry are helping us explore new energy materials for a low carbon future.
Saiful has asked the Q&A not to be published.
Saiful Islam is Professor of Materials Chemistry at the University of Bath and presented the 80th anniversary Christmas Lectures in 2016 on the theme of energy.
This discourse was filmed at the Ri on 25 January 2019.

Fantastic lecture - it achieved it's purpose of appealing to a wide audience. You didn't need any knowledge of the subject before watching as there was enough introductory material to put in context. I watched this with my 91 year old mother in law, my teenage son and my non-scientist husband. I myself am a scientist working in a different field. All of us took something from the lecture and were interested throughout. I recommend this as a good watch.
It's wonderful that this resource is online and accessible to all - beyond the 400 or so lucky individuals who were in the audience at what was an extremely enjoyable event. The attendees were peppered with Faraday Institution HQ staff and researchers who work in this field, but Saiful has such a gift of making science accessible and engaging to everyone - young or old - whether they have a scientific background or not. Well worth a watch.
Another brilliant Ri talk from Saiful on one of the toughest challenges of the modern world. Congratulations!!
Great lecture form an absoluetly top class scientist who knows his stuff and can get across the key points with a sense of humour. Thank you.
One of the best speakers on Ri, loved the puns.
Moltex Energy's SSR salt cooled reactor can vary it's output between 150MW and a few GW by melting a sodium vat.
It uses the heat from the reactor and/or hot salt to run its turbine.
High temp gas turbines too.
And it's hot fast neutrons too, great for directly making hydrogen and desalinating water (important here in the UK)
Really lovely lecture, well done.
So many great achievements and yet John still isn't deemed Goodenough for the Nobel Prize?
I waited for that comment
Really enjoyed this. Thanks Saiful
8 minutes for light to get to Earth from the Sun not 8 seconds for those who didn't know.
Excellent clear talk. Liked the slides on battery and solar cell materials (and the puns!).
I have a family friend with the same name so I got excited haha. Unfortunately, it wasn’t him, but it was a great talk regardless!
You know nothing
8 light seconds, damn, they've implemented significant upgrades to the speed!
Overclocked photons. It's the latest rage...
Shouldn't that be a DC Cobra?
Saiful i salam
Ok
I dunno English sad.
24:42 I don't understand that graphic...WattHour/Kilogram of material, from 265 efficient to 300 efficient and the car can doble the miles?
I'm just going to guess he didn't mention something else like lighter materials to build the car and more efficient engines with less wasted energy and all that.
I'm puzzled by the same thing, and especially giving a total range to begin with. I mean why can't you just slap on 2x the batteries and have (close to) 2x range? is there a limit for diminishing returns or something? if that's the case, I can understand how a slight improvement in energy density could double the range. but I'd be extremely interested in what kinda curve that's based on, and how do you get that curve to begin with.
@@babstra55 increasing the weight reduces the range a lot. The most efficient EV (at the moment ) the Hyundai Ionic also happens to be on of the lightest.
Eight seconds, for sunlight to reach earth? I think not.
A well conducted lecture, charged with inspirational intellect. The current state of solar energy is amazing! Also, with all those puns, I wouldn't be shocked if Saiful is a potential fan of Master Thereon.
I was wondering why he didn't apologize for the the messed up slides, but they are only in the video, the ones projected in the room are fine. So it's the video editor's fault. Slide presentation software often handle changing aspect ratios very poorly. Since the RI is most likely to keep projecting in 4/3 aspect ratio, and the videos are gonna stay at 16/9, you should really be more careful in the future.
Sorry, a couple of slides slipped through! We can prefer to project in 16:9 in the theatre but sometimes for various reasons, our presenters go with 4:3. We're usually pretty good at fixing them in post but sometimes we make a mistake or two.
22:10 "... he had to fly back to Russia ..."
LOL, not in 1889 he didn't.
Electric cars and short journeys are all well and good.
But nobody can afford more than renting a crappy flat with no parking or less parking spaces than how many flats there are.
I own my flat, we have 15 parking spaces and 50 flats and the housing association will never install charging points unless it's at gunpoint.
They won't even fund our hospitals, police and firemen anymore.
When are they ever going to spend the umpty billion pounds on digging up all the pavements and car parks, both public and private, for anybody but those who can afford to live in a house with a garage in a village or suburb.
You know, almost all the people born after 1980.
A token handful of barely standardized, usually broken, charging points at a Welcome Break aren't going to cut it.
Oh and unless we're lucky our economy is about to be sacrificed in the name of some angry Brexiteers. Can't see the surviving corporations buying me a charging point.
You have a very pessimistic view of the future.
Ok things are not looking good at the moment what with our useless politicians here in the UK and in the USA . However solar and wind power are now cheaper than any other way of producing electricity. Battery tech is making breakthroughs all the time increasing capacity, reducing weight, extending battery life and removing both rare, removing poisonous compounds and becoming far cheaper.
Grid tied battery packs will largely decarbonise the production of our power grid.
Within 5 years electric cars will both have an average range of over 400 miles, recharge from 20% to 70% in 5 min and both cost far less and last many decades longer than current fossil powered vehicles.
Actual ownership will not be an issue. Self driving taxis will be where you need a lift from and take you to where you want to go too within 10 years.
Already electric cars currently have ranges upto 600 miles at motorway speeds! They are admittedly expensive at the moment but this will change. Chin up get some qualifications that employers want and work hard, you too can have a happy (er) future.
Yes we live in revolting times but not all things in the future will be bad.. although moving abroad after brexit might be a good move. Were our useless politicians (both those in power and those wanting to replace them) be not trying to destroy our country one way or another we would be far better prepared for the future.

(Sorry, couldn't resist!) :-D
Please how can contact him please help me,🙏😭🙏
Hi it's me saiful islam
When I think of Entanglement I keep coming up with something hard and massless. Waves need time hard things move all at once. Hard isn't real anyway even though it kinda is.
2:41 Watts new, nice pun
Are you on a phone or pc? Regardless you should turn down 4watt in your settings.
We can now, do partal charge, in the time for a potty break, or while eating or shopping. It's possible to charge 30-40% in 10-20 minutes or less, that should be plenty, we just need charge stations, maybe mobile charge stations! Capable of 100kwh, or so. Would be great. I only usually travel within 20 miles a day, and about 60 miles a week, normally, but I have done over 100, in town in a day. But my town is scattered, and covers a large area. Like near 20 miles across town, being just out of town driving into town and back, a couple times a week, so near 20 miles a day, 40-60miles a week, so ev would make sense. We need to offer ethanol, and have ethanol turbine engines, or even piston engines, for range extenders! Ethanol can make alot of power, like used the race car engines, burns clean, a engine designed to run on ethanol can make alot of power in a small engine, use that to generate power, over propelling the car, would make more sense, and the enging at a constant speed, would be more effiecent, generating power to charge the battery and power the car, something like 80+kw should be easy and with a small piston engine, possibly smaller with a turbine engine.. Basically using motorcycle engine technology, to power a generator, I don't see why this isn't available Now!!!
Half the video was a bit of a long intro most people would just aboid it, is all the basic you learn on any other battery introduction.
miaow
i like how he acknowledged our last president, not our current one: edit, guess he gave this lecture the year it all went wrong.... 2016
#Si
31 mins in and he finally talks about the subject of the video. Come on now.
@56:58 shame on who if you spell Institvtion? Pun went wrong 😛
Too much side talk
JUST A HEADS UP TO Ri. your intro is very tortuous to the sensory systems of us highly sensitive people. it almost drives me away from the channel.
It's on our list of things to change this year!
#poppahTea
Worst jokes ever !! ;-)
"Saiful has asked the Q&A not to be published" what happened there then a pun competetion got out of hand?
A bit too much filler, maybe 25% filler content. Puns not so bad.
If one doesn't already know the subject, then this talk doesn't make any sense. Just words salad.
If one already knows the subject, than the talk is redundant. Just a random Captain Obvious recap.
No matter what, you lose (about an hour of your life).
:o\
Mmm No, yes you do need a bit of background info. But most 11 year olds and above will get a lot from this.
It seems that anyone can speak nowadays in the RI
What do you aim to criticise?
Ahh racism raises its head even here. I have news for you George of the Jungle, Brain power has nothing to do with skin colour. Look at American presidents. The mist intelligent president they ever had a dark skin and look at what replaced him? Possibly the most stupid person not being kept under lock and key in a prison or care home.. he has white skin. That says everything anyone really needs to know about white supremacists.
This was one of the worst lectures I have ever watched.
Why
@@ozhoneybadger My opinion.
@@ayman3041 Back it up with facts. Before I deliver my own lecture
@@ozhoneybadger I've no time.
@@ayman3041 Then shut up. Before I slam the chemistry out of you.
