I still am waiting for Graphene to deliver a tenth of what was foretasted. Graphene has good company with Fuel Cells and every single new battery technology over the past 20 years.
- toufiqbarhamov 8y agoGraphene has a big advantage over them, although it is slow to deliver. New batteries or affordable fuel cells require breakthroughs in materials science, especially in the case of fuel cells. Inventing novel, cheap, mass-produceable catalysts to replace something like platinum, or a novel battery chemistry is a monumental challenge. Graphene already exists, but the propeties of the material are complex, and affordable mass production at the desirable scale is prohibitively expensive. Still, it exists, it can be made and manipulated, but a lot of exploration into its properties remains. I’d expect Graphene to be useful with a couple of decades, possibly sooner, while I wouldn’t even venture a guess on breakthrough batteries or fuel cells.
- ianai 8y agoThe solid state batteries from ionic materials (https://ionicmaterials.com/ https://ionicmaterials.com/) seem very promising in a quicker timeframe. Ie I could imagine them being able to fit a much higher density in the same volume given the stability of the material.
- toufiqbarhamov 8y agoFirst I’ve heard of this company, but some Google-Fu reveals a lot of reasons to trust your optimism. They apparently got a $3m ARPA-E grant as well, and are producing something that works through a range of temperatures without forming denrites. Plus an increase in energy density of 115Wh/kg, while increasing stability and safety, even to rupture. Wow!
- joe_the_user 8y agoIt seems like graphene production at scale is something states should be putting money and resources into. It's the kind of thing much more amenable to a "new Manhattan Project" than something like AI.
- vkou 8y agoThe Manhattan project had an immediate, predictable return to its funders of "It will let us kill a lot of fascists, really quickly." Cui bono? Who will benefit from the DOE sinking a billion tax dollars into building graphene fabs? Will that benefit be greater then sinking it into something else?
- r00fus 8y ago> Who will benefit from the DOE sinking a billion tax dollars into building graphene fabs? Isn't that the answer that {your_country} should own these industries before China/Russia/etc does? Because you can bet China is investing. I know someone who used to be the general manager of a large Chinese manufacturing plant, and all he wanted to talk about was how graphene was/is/will change whatever industry/tech I discussed. From a US perspective, there's billions wasted on make-work programs (TSA) and corporate handouts and subsidies that would greatly increase the tax base and develop local markets by reinvesting instead into new tech.
- vkou 8y agoWhat does it matter to me that Boeing is an American firm, owned by a bunch of international institutional investors, as opposed to a Korean one, owned by a bunch of international institutional investors? Is it because there used to be a Boeing factory in my town, before they moved all the jobs to somewhere cheaper? To put it another way - why should I care that a few private companies in {my_country} own these industries? Their owners aren't paying me dividends, I'm not going to pay for their R&D. If you want to sink this money into building a state-owned industry, where the profits are distributed between the people, sure, that's another story, we can talk about that. If not, appealing to nationalism is a poor motivator for me to fund your cottage industry. If you want my money, make me a shareholder. > From a US perspective, there's billions wasted on make-work programs (TSA) and corporate handouts and subsidies that would greatly increase the tax base and develop local markets by reinvesting instead into new tech. So, the solution is corporate handouts for industries that you like? Handouts for people growing corn, or groping your junk when you cross borders are bad, but handouts for people making graphene are good? (Unlike corn, the jury's still out on whether or not it will actually be useful. Maybe it's the next plastic. Maybe it's the next beanie baby. Maybe it's the next asbestos. It's too early to tell, and "Let's manufacture tonnes of it, before anyone has any use for it" is a solution in search of a problem.) I mean, sure, our current allocation of spending is probably not optimal[1]. I do think, that the onus is on you to demonstrate that sinking a billion dollars into building a graphene fab is better then sinking a billion dollars into killing fossil fuels, or shrinking classroom sizes, or providing free early-age child-care, or free flu shots[2], or any one of a dozen other things we should be doing[3]. [1] To be fair, I am 100% certain it is not optimal. [2] http://info.totalwellnesshealth.com/blog/bid/190040/How-to-Measure-the-Value-of-On-Site-Flu-Shots http://info.totalwellnesshealth.com/blog/bid/190040/How-to-M... - The ROI of a flu shot is >200%. [3] Not to mention that a lot of the time, being the first mover in an industry is unnecessary. Let someone else figure out if something is worth doing. If its that important, a sovereign state can always catch up, and develop a local industry, through incentives and tariffs - once the field is proven.
- Tossrock 8y agoI'm still[1] waiting on those silicon nanowire batteries. 8 more years! 1: https://www.reddit.com/r/science/comments/dnlnf/breakthrough_edisplay_means_electronics_with_high/c11kkmu/?context=3 https://www.reddit.com/r/science/comments/dnlnf/breakthrough...
- candiodari 8y agoThing is, we know what those are, we can give you a plan that will work. We can give you an atom-by-atom plan of those. We just can't make them (and we're very far away from that atm). (and yes a pretty good criticism is that we could 4x or so current battery designs' performance as well given atom-by-atom manufacturing capability)
- philipkglass 8y agoThey're being used now, albeit only in cost-insensitive applications like drones: "Amprius' Silicon Nanowire Lithium Ion Batteries Power Airbus Zephyr S HAPS Solar Aircraft" https://www.prnewswire.com/news-releases/amprius-silicon-nanowire-lithium-ion-batteries-power-airbus-zephyr-s-haps-solar-aircraft-300759406.html https://www.prnewswire.com/news-releases/amprius-silicon-nan...
- api 8y agoIt usually takes more than 20 years to go from lab bench to wide application.
- Tade0 8y agoGraphene has good company with Fuel Cells and every single new battery technology over the past 20 years. They're here and in use. To give an example NMC batteries, which enabled smartphones, hoverboards, cleaning robots and other gadgets have been around since 2008 or so. EDIT: grammar.
- kybernetikos 8y agoI remember what it was like 20 years ago. There were a whole host of things we didn't have, at least partially because battery technology was so much worse.
- soperj 8y agoIt took about 20 years from the first proposed lithium batteries until the first commercial one in 1991, at it wasn't until the last 10 years that they've really taken off.
- baldfat 8y agoNot sure why all the down votes but we still haven't found 14 years in how to use it in a consumer device. http://www.mining.com/these-are-just-15-ways-in-which-graphene-could-reshape-the-world/ http://www.mining.com/these-are-just-15-ways-in-which-graphe... "But after 13 years since researchers first created the revolutionary material from graphite, consumers is still waiting to see some of the touted applications in the market." 2017
