The first Lecture from Professor Saiful Islam’s 2016 series of CHRISTMAS LECTURES, ‘Supercharged: Fuelling the future’.
2016 marked the 80th anniversary since the BBC first broadcast the Christmas Lectures on TV. To celebrate, chemist Professor Saiful Islam explores a subject that the lectures’ founder – Michael Faraday – addressed in the very first Christmas Lectures – energy. In his first lecture, Saiful investigates one of the most important challenges facing humankind – how to generate energy without destroying the planet in the process. As part of the celebrations, Saiful invites former Christmas Lecturers to join him on stage, and repeats some of the most exciting (and dangerous) experiments and demonstrations from the past.
Saiful begins his lecture by being plunged into darkness. Armed initially with nothing but a single candle, his challenge is to go back to first principles and bring back the power in the energy-hungry lecture theatre. Along the way he explains what energy is, how we can transform it from one form to another, and how we harness it to power the modern world.
A fascinating and stimulating celebration of the stuff that quite literally makes the universe tick –- the weird and wonderful world of energy.

Wow
Interesting for such short video!
I love this Channel but this Video was way too short on this interesting topic 😀
When?
lol, he said "doodoo" at ~0:41
Fusion is 50 years away… again.
Is Fusion ever going to work?
fascinating
Tokamak 1 for further reading
So how was the plasma in those tubes made if they werent hotter than the core of the sun?
0:00 RIP headphone users
https://youtu.be/EBwn1pqx1hU Thermonuclear fusion is pseudoscience. The TOKAMAK project will fail. The phagocytic nuclear reaction is a "thermonuclear fusion." The pressure converts a hydrogen atom into a neutron. Pressure helps the nuclear reaction, the temperature hinders. http://www.facebook.com/Статическая-теория-атома-163704797446539/?ref=bookmarks
The creation of a reactor for a hydrogen nuclear reaction can be solved in 3-4 years.
He just showed plasma, Plasma isn't fussion its plasma.
If you want fussion you need a fuel like hydrogen with extra isotopes like deuterium or tritium.
The reaction chamber needs to be very close to full vacuum. When the deuterium and tritium are flying fast enough and collide, It will fusse to helium and some protones and electrones.
1 helium 4 atom is lighter than 2 deuterium atoms.
That means Mass is converting into energy and I mean a lot of energy.
The main thing isn't only to hold that 14 million degrees Celsius Plasma.
Because you can apply an electrical field to hold it. But how are we going to convert 50 million degrees plasma to sustain itself and produce clean and efficiënt energy is more of the biggest question. And there is many more to discus about the world leaders and deffence why they are supporting nucleair fission…
you could burn hydrogen in oxygen, it’s photovoltaic then use magnetic induction and bridge rectifier back to dc for water electrolysis. the waste heat energy can be used to boil water ?
Sick!
Please correct me if I’m wrong but if you get 10 times the energy out as you put in couldn’t you then direct 1/10 the output back in and set up a perpetual motion machine of sorts?
His explanation of what plasma is really sucked.
