i’m not sure you and i are in any way disagreeing

Right, I misunderstood what you meant by "production" of elites, & how much you meant "the current university system" by "education". Sorry. But I still feel there's some dispute... Investors do *try* to invest in the kinds of people you suggest, and then keep losing money.

So the question is, what are they doing wrong? And I think we have some disagreement on *that* point. Bill Gates invests in, say,
@DanielleFong. She's smart. She has an idea. The startup fails. The pattern repeats, again and again. So what's the problem?1 reply 0 retweets 0 likes -

Would you *like* a more in-depth analysis of your particular case? I can do that, if you're sure you want one!

there’s probably no way to do a very good job at this without details that have not been published, so i deleted my tweet the background situation of 4 cleantech funding busts (07-09,11,14,15 china, ‘16) & exponentially dropping li ion cost is probably the single biggest factor

No, compressed air energy storage was never economically viable. Not with underground caverns, but *certainly* not with compressed air tanks. I told you at the time that if you could actually make much cheaper compressed gas tanks then you should sell them as CNG tanks instead.

And that's what LightSail tried to do, towards the end. But more fundamentally, gas turbines aren't efficient enough for CAES to be worthwhile. Pumped hydro works fine because water turbines are much more efficient, but CAES needs to buy electricity for half its sale price,

we increased the efficiency of our reciprocating compressor by a *lot* we more than doubled the round trip efficiency, and you can use the waste heat and cooling that produced in buildings, use waste hear during expansion cycles

Oh, a piston "wet compression" cycle? It so happens, there was a paper this year specifically covering your design for that, and...the efficiency isn't any better.https://www.sciencedirect.com/science/article/abs/pii/S019689042100203X …

scihub is frozen this year and i’m not buying an analysis of my own project, but at 15C delta between water and air is a pretty minimal exergy hit (~10%) but it’s definitely not the same efficiency as adiabatic or as natural gas assisted caes
