I think there's no question that the Li-Air battery is one of the most important, game changing technologies that we'll see in the next 10 (hopefully) years. It changes everything. It's not just about better battery life on your MacBook. There are so many things held back right now by poor battery technology.

Quadcopters will have better range, among other things, allowing them to be used for more things.

Sorry to be skeptical, but I can't help but think: Number of "battery breakthrough" news I heard in the last 15 years: >100, Actual battery breakthroughs: 0

Batteries have become vastly better over the last 15 years. It's just that this stuff ends up as gradual progress, not sudden jumps, so you don't notice it unless you're looking for it.

"Today, with graphene and carbon nanotubes and fancy membranes coming out of our ears" Made me shudder. One, for the violent imagery, two, for the trivialization of remarkable science and technology.

'coming out of our ears' is a colloquialism meaning roughly 'more than we know what to do with'.

It was a joke... visualize tubes coming out of someone's ears. Just because it's a colloquialism doesn't mean you should ignore the imagery it conjures.

If I read this right, much of the weight reduction is because a large component of the electricity-generating reaction is already plentiful in the atmosphere, so it doesn't have to be carried around with the battery.

But as the battery is discharged, the oxygen molecules are altered (according to the video) and presumably stored in the battery - which implies when discharged, the battery gains (significant?) mass. During charging, the oxygen is released again, so the weight goes down.

Is that right?

IE6 worries you? There's Lotus Notes!

Oh god Lotus, very few things are worse than IE6, VERY few.

Hey, watch it! We use Lotus Notes at work. - "It's what the President already knows." "Oh...good reason." =)

This is slightly off topic but simply stated I just love IBM these days. There aren't many corporations that dedicate as much focus on research and yet, for a large corp. they also keep their nose surprisingly clean (these days). While we watch the swirling tech scandals ebb and flow they just quietly sit off to the side and keep changing the world.

I work for a help-desk part of IBM. We use IE6. :(

Sorry to take a tangent here: Curious what you'd say about someone who is moving to NYC and thinking about what kind of work to find. Formerly worked for one of the big SV tech companies in a project management role. Would love to work for a smaller company now but there aren't as many tech startups in NYC so perhpas IBM is the best bet.

How do you like working there all in all? I understand hierarchy and bureaucracy are the name of the game back east, especially at big blue, but I suspect this will be nothing new... and that SV just claims to be more flat. But would love to hear your perspective and whether it's fulfilling in your org.

That should be very rare these days http://www.sutor.com/c/2010/07/ibm-moving-to-firefox-as-defa...

If ISSI (internal software updating tool) hasn't hit you yet, it's very possible to still be running IE6. ISSI can't hit everyone all the time. And there are still apps that can't run on Firefox, so needed IE (6 if not a newer version of IE). (IBM PM during the day here)

It really depends on your department. Some people get to work on the really cool and fun stuff. The stuff that gets IBM so much respect on HN these days, most people inside IBM never even touch. Then you have other areas, where there are internal applications that still rely on IE6 and have horrible interfaces (edit: and yes, Lotus Notes is really truly the application that should not be named :D).

You're right, hierarchy and bureaucracy are name of the game, but that's true in any big org. You're probably best off asking someone who's actually working in the department where you'd be applying. There are so many departments and each one has their own culture, processes, etc. Someone who complains or is happy about stuff in one department is most likely not reflective of another department.

For the record, my department isn't exactly great, but they're giving me the opportunity that I actually care about (an opportunity to live in China so I can learn Mandarin).

Thanks for the reply! China sounds like an awesome gig. I did some time in India with my last gig but China would have been the preferable option... at least for me.

Anyway to be honest I sort of like the idea of honesty about being hierarchical. Sometimes SV's claims of flatness feel like propaganda and rub me the wrong way when they're not realistic.

I can imagine what you mean about most people not being on the really cool stuff: I can see that IBM is keen to develop really awesome stuff that doesn't necessarily make money but which ensures IBM's brand is synonymous with innovation. Better than splattering coke and pepsi signs across the world's cities after all :)

Cheers!
