Re: SolidEnergy - 13 Wh in 29 g li-ion cell - any independent confirmation?

Excuse me, I guess I wasn't right either. This is Li-Metal which is apparently different than solid state lithium... I guess I need to go read some. I did find this: I contacted SES (Solid Energy Systems) yesterday, because the specs of the Hermes battery cell had a typo, I used the opportunity to a...

Re: SolidEnergy - 13 Wh in 29 g li-ion cell - any independent confirmation?

After they made press last August claiming a breakthrough, I checked up on them every couple of weeks. It has been crickets and had been assuming this was another false hope. Perhaps it still is, but happy to have hope still alive.

Edit: ... also, this is for a solid state lithium battery, not Li-ion

Re: SpaceX News

I too would love to see some excess landing fuel mass burned off using 'weight management maneuvers'! :) Well, if that was ever going to happen, it would be the next launch: 475 kg to LEO. (Contrast that with July's launch of 6,761 kg to GTO). Heck, maybe they'd even have enough fuel left for a tou...

Re: Placing humans at center of computer optimization yields hot plasmas

Another article about it at Popular Mechanics.
I had no idea Tri-Alpha and Google were working together (says they started working together in 2014). Should I have known this?

Re: SpaceX News

...except that I guess SES-11 was delayed and there will be no launches for more than a month after this. Looks like the pipeline needs a better branch predictor?

Re: SpaceX News

A sweep of the weekend double-header! Static fire for July 4 launch as early as Thursday. Clearly, they seem to be having success in bumping up the launch cadence. With 2 successful re-uses, I expect the dominoes will start falling quickly in terms of customers willing to ride the "flight-prove...

Re: SpaceX News

Interestingly, they just bumped the odds of go from 60% to 70% Saturday. Today's radar looked nothing like a 70% go day (as it was supposed to be). Here's hoping for better on Sat.

Re: SpaceX News

That sounds like a pretty direct competitor to Vector Space Systems.

Wonder how many players the micro-satellite industry can support? How big can it get without making space junk an unmanageable issue?

Re: SpaceX News

I'm guessing not really. I think the big issue issue for the 2nd stage is that it will be going that much faster and thus will require that much better of a heat shield and/or fuel to slow down. Not clear to me how this translates into recovering the fairings which strikes me as likely more of an ae...

Re: SpaceX News

It has been frustrating to try to understand progress they are making on fairing recovery compared to the booster recoveries where we got to watch every attempt. I wonder why SpaceX is being so secretive about the fairing recovery attempts? Also, I'm a little surprised the fairing isn't susceptible ...

Re: More Helion Energy news....

Hi there, RERT! Been a while.... Yes, many industries do have special breaks and subsidies that apply to them, so I suppose oil is not terribly special in that regard. Still doesn't make it right or or make it not a subsidy. I bet the effective tax rate is (besides being a dubious cherry picking of ...

Re: More Helion Energy news....

Say there was a big corporate tax break and repatriation of trillions... this would certainly help the US economy (possibly at the severe expense of our kids?), but I suspect not so much help high-risk ventures like fusion. If someone is looking for a high-risk, big-payoff investment, the individual...
