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

They seem to be in exactly the same place they claimed to be about two years ago. If you look back to two years ago in their original press release and news stories (too lazy to search right now), pretty much the same as that too. Actually, I think at that point they were projecting cars in two yea...

Re: Mach Effect progress

That's the claim from the thread TDPerk linked to : BTW same kind of casualness in their EmDrive testing, as already reported on these boards in the dedicated thread, for example here and there. ... Part of the reason that Tajmar's group published on two different drives was an attempt to show how g...

Re: SpaceX News

... I mean, if it has rockets, it's at least a little relevant?

Re: SpaceX News

Actually, I think NASA wants 7 launches in a "frozen" config. They have launched block V as of last month... but that was a version without the new COPV tanks. First flight with those doesn't come until August I think. So they need 7 flights from that point.

Re: SpaceX News

Also, as a minor point, as I understand, there will be no "Block 6 Falcon 9". They have capped the program at Block 5. There may be some 5.1, or 5.1.1 stuff, however, I am pretty darn sure that they came out and said end of the design train for Falcon. Absolutely no disagreement there; block 6 was ...

Re: SpaceX News

You missed my point: Given: Keys to BFR being cheaper than F9 = 1) Full re-usability 2) High volume of launches 3) Re-usability without refurb across 100x launches ...and given: Stated goals of block 5 = 1) Full re-usability 2) High volume of launches 3) Re-usability without refurb across 10x launch...

Re: EM Drive

A new attempt to validate/disprove EMDrive and Mach Effect has been attempted.

Re: SpaceX News

Less ground crew and far less expensive fuel. Also, 100 minimum launches before refitting means the not10x R&D cost is spread over far more flights. Fuel cost is only a little higher for far more capacity. Ground crew cost is far lower. R&D $$$ to be amortized per flight is far lower. Total cost to...

Re: SpaceX News

Per above info, they are aiming for F9 2nd stage reusability. If they can achieve that, not sure how BFR could possibly be cheaper to launch.

Per: https://www.reddit.com/r/SpaceXLounge/comments/8ii206/elon_musk_quotes_today_prior_to_block_v_first/ SpaceX on track to double their 2017 launch rate. Source Arguably version 6 of Falcon 9.

Payload is not boring! I'm praying this launch, more than any others, goes off without a hitch!

Re: Small Tri Alpha news blurp

I found the 8¢/kWh target disheartening. Nevermind gas, even wind/solar + storage is going to be beating that before TAE would have any potential to have something to market.

Re: SpaceX News

As I wait to wait today's launch of CRS-14, I am wondering why they are not recovering the recycle flights to pick apart for use stresses of multiple flights. It would seem to be a potential wealth of knowledge they could carry forward regarding engineering and material costs. I was thinking the sa...

I was just noticing they have 5 (!) lined up for April. Looks like they're trying hard to have the next 50 done in a year.
