The First Sodium-Ion Rechargeable Battery
I both love and hate stories like this: I love them because it is amazing we&#x27;re still finding new ways of making batteries; I hate them because at least 3&#x2F;4th never make it to market, and the ones that do usually take about a decade.<p>Example: ubiquitous high speed front side bus interconnects between devices. Infiniband, Thunderbolt, RDMA over Ethernet, multi-host USB 3.x networks, whatever. Getting cheaper? Yes. Ubiquitous? No.<p>Example: Freesync being deployed everywhere, in monitors, on phones&#x2F;tablets, being added to HDMI and put on all future TVs, and finally just eradicating a ton of processing latency in the display and getting UI responsiveness I last saw when all analog VGA CRTs existed. Is that a thing yet? No.<p>Example: Internet so fast that latency basically vanishes, and the last mile is no longer a liability, thanks to ISPs like Google Fiber proving it is cheap, easy, and <i>required</i> to deploy. Do I have Google Fiber or anyone else standing up to the challenge yet? No.<p>Example: A smartwatch, in the vein of Google Wear or iWatch, that has a week+ battery life, and can do various action tracking shit that Moov has been pioneering, and has actual working heart rate tracking, and has water proofness measured in tens of meters (so I can go swimming with the thing on if I so choose). Is <i>that</i> a thing yet? No.<p>All of these have been promised to me in the past decade. I&#x27;m tired of getting my hopes up, but hope is one of the few things I have left.
