No, that isn't what vaporware means. Vaporware means a technology promised, but not delivered. What it doesn't mean is a technology promised, and successfully delivered, and at the beginning of its growth curve as supply of the en

I don't think you know what the word "vaporware" means. 1 GW per day of new solar is being installed globally. Where do you think the excess mid-day production is going to go? It doesn't have to go anywhere, actually. Bu

Without telling you anything groundbreaking, around 80% for PEM. It's more than acceptable when you look at how much excess solar production is being built.

Green hydrogen is developing now, and is very real, and is based on polysilicon solar advancements and PEM electrolyzer advancements, both of which provide ~3 decadal cost-down paths. See these two companies of ours: [1] https://

The oil companies don't own many pipelines. Pipeline companies own those. And pipeline companies are eager to do business with hydrogen companies. The fight here is over whether natural gas-made hydrogen (SMR) is an interesting fuel at

Are you referring to hydrogen as a mobility fuel specifically? I generally agree. However, it is a critical large-scale industrial input, a replacement industrial input for several additional large industries, and an excellent large-scale s

The jellyroll li-ion batteries invented by Sony, perfected by U.S. firms, and their IP then stolen and maximized by Chinese firms (namely CATL), are an inelegant, imperfect, and in many cases fundamentally dangerous design. And those compan

The issue is that utilities spend more than 50% of their incremental operating expense getting that electron to you, not making/buying it in the first place. With that kind of cost-stacking, nuclear has little hope of competing with so

For those who haven't seen it, worth looking at BrakeFlow, a feature of the new Si-anode Enovix batteries. Demo: https://www.youtube.com/watch?v=Y8eSEoOy8JY

I suspect this is exactly how it is going to go as higher density Li-Ion comes out around 900 Wh/L.

Central gov't making statements to quell a bank run is one of the few things most libertarians will always say is properly in the federal toolkit.

You are being downvoted but there are really people who think like this. Regional banks do not have a substantive underlying issue and do not deserve to die by a rotating regional bank panic.

This lower power modem and the Enovix Si battery and we're looking at 5G for real, finally.

Enovix is already at 1,500 cycles w/ 88% capacity retention at *889 wh/L per core* (figure ignores packaging, like the Argonne figure) at 6C CCCV charge – 1C discharge. And that is a commercially relevant sized cell that is being

The real future is a fully distributed series of microgrids, which affords all of distributed generation, smart grid coordination, and resilience. If you want to work on this, think about joining Enphase, which makes grid-forming microin

Happily, you are misunderstanding their filing. They do have working prototypes which meet the announced specs. They also have a plan to push beyond the current (and very impressive) 900 Wh/L energy density.[1] It is those future-loo

Hi Dan –– this is definitely not true. Enphase offers long-dated warranties of up to 25 years on its systems and equipment. This comes as the dividend of serious work on hardware and software quality.[1] Opening an app certainly isn't

That's hard to do without enabling the massive industry of low-brow leadgen companies to scrape data and make the spam problem even worse. But I hear you. I will look at it.

For anyone wanting to work on problems like these at commercial scale, check out Enphase[1]. We build real AC microgrids that perform realtime energy production and consumption calculations to enable true microgrid orchestration with or wit
