Donald Sadoway: The missing link to renewable energy
www.ted.com What’s the key to using alternative energy, like solar and wind? Storage — so we can have power on tap even when the sun’s not out and the wind’s not blowing. In this accessible, inspiring talk, Donald Sadoway takes to the blackboard to show us the future of large-scale batteries that store renewable energy. As he says “We need to think about the problem differently. We need to think big. We need to think cheap.”TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world’s leading thinkers and doers give the talk of their lives in 18 minutes. Featured speakers have included Al Gore on climate change, Philippe Starck on design, Jill Bolte Taylor on observing her own stroke, Nicholas Negroponte on One Laptop per Child, Jane Goodall on chimpanzees, Bill Gates on malaria and mosquitoes, Pattie Maes on the “Sixth Sense” wearable tech, and “Lost” producer JJ Abrams on the allure of mystery. TED stands for Technology, Entertainment, Design, and TEDTalks cover these topics as well as science, business, development and the arts.

for? me the best Professor “online”
According to Wikipedia Antimony is a rare metal. Only 120 000 tonnes produced per? year. Worse still, reserves at this rate last only 15 years. Dirt cheap material???
Hello! Thank you for this useful video. By the way, I notice lots of people keep on talking about Xobotano Home Energy (do a search on google), but I’m not sure? if it’s good. Have you tried using this alternative home energy known as Xobotano Home Energy? I’ve heard several great things about it.
The Solution to renewable energy is that special material that in reality, it does nothing.? Find it NASA.
this is? great video
Thank you!!!!?
Anyone making any kind of second law of thermodynamics argument? disputing this neat idea working is the sort of person who thinks that you can’t slow down entropy, thus the classic metaphor: a messy room can never be clean. It’s horseshit. *SHRUG* Take resources that you have, and use them to improve the management of said resources. You don’t abandon ANY resource. Ever. Period. You abandon a resource has when it has been USED UP. If not, it’s idiocy to not keep it on-hand, say, for emergencies.
As a substation electrician apprentice the heat these things generate makes me nervous as it pertains to maintenance. Wont this thing demand a hell of an inverter? if you put one of these in every wind and solar generation yard are? you suggesting we produce the power in dc? What is the projected life of this battery?
As a Conceptually this talk is on point but it leaves me with so many questions technically.
Pat? MIT Professor Donald Safeway has the answer for renewable energy.
I see this broad-minded, inspirational, high-tech thinking people, and I wonder why I live among stupid people who believe? the bigger their cars are, the better they are.
Wait? for the chinese to rip it off and bz out the american producers like they are doing with steel.
I thought about that, but heck man, I’m only halfway through first year Chem, I have no idea. I’m just going on what he said, and if he’s a prof at MIT, chances are he knows what he’s talking about and? he’s got it figured out.
Right, but wouldn’t that require that the battery always be connected? (Is there current inside a disconnected battery? I googled the question, and nothing popped up immediately) And for that matter, how do you start the battery? up? Presumably after shipping it would be solid. Heat it? How?
The battery generates heat, but you need an insulator of some sort. Noted that in the 2MWh design, they had it in a shipping container – I’m assuming that’s what they’ve decided to use as such. Makes sense, the system is still pretty cheap relative to other battery technologies, running price for 40′ containers looks to be on the order of $3500 or so. Can’t wait? to see developments!
Wow. Impressive plan, good luck! I know a lady who lives off grid, but I have no idea how she stores the energy? from her solar panels.
must have missed that, I’m wanting to make an off grid house and wondering if this could work as a practical alternative to? a battery bank. I think a 25KW cell would be more then enough, but I’m not sure if it I could produce enough extra power to keep it that hot. but I’ve heard the goal is $100 per KW so it could be worth it to just buy extra solar panels.
The electric current running through the? battery will encounter some resistance, which generates heat, creating a self-sustaining cycle, allowing the battery to continue running. He mentioned this in the video.
What really cooks my noodle is not that today’s computer-driven grids can maintain constant load balance, but that this was managed back in the days of Edison.
I hope? this battery technology pans out, but I’m not smart enough to comment meaningfully.
I accidentally wrote the words NO in capital letters as I was touch typing and I’m sorry if that typo hit your grammar nazi nerves.
Ok, fine? if you want to be picky I will concede the point of LFTR’s not having any waste. However? they do produce significantly less lower level wastes that it’s a negligiable amount at best.
I will also concede that the same amount of high level waste i.e the rods will of course be produced. But this is a small and easily manageable amount
India announced their intentions on? building a thorium reactor.
Hoo rah!
sorry if this is? a stupid question, but how do you maintain, I’m guessing 1200 F all the time?
this will change the world if it? becomes massive..
