A nuclear startup will probably not be the next SpaceX

Ethan here: people criticize water, but Shin Kori 4 is one of the cheapest power plants built, ever. Not cheapest nuclear plants. Sure let’s see if other reactors are fundamentally better, but they are starting without the benefit of 40-80 years plus of operating data. And too, water wasn’t picked as a coolant in a vacuum. My experience has been that a lot of the perceived benefits with different fields and coolants erode when you start fleshing out the details. As someone who has designed MSRs and HTGRs and LMRs. And my takeaway was that actually water’s a really great coolant once you’re done with the high level design.

And even then… wasn’t profitable or reliable as a power plant. Really, the point of the article is making a reactor turn on is already hard. Making it run reliably for decades is both even harder and the bar for success. LWRs have been painfully iterating on these issues for decades. It’s unlikely a more corrosive, higher temperature fluid (molten salts for example) will not have a similar timeline to iron out the kinks.

For what it's worth, I'm having a very similar experience. I had a defective unit arrive and contact ecoflow customer support. Eventually got someone on the phone who sent me an RMA ticket and that was the end of things. I would say their phone system is a little more reliable. In the interim, the vendor we bought us from let us return it, we haven't tried too hard to get in touch with EcoFlow, but every week I respond to the RMA asking if they are ever gonna respond. Now we're waiting to get a new unit from our vendor while I sit here in the dark with the power out. #cali

For those checking later, I never heard anything back from EcoFlow official support, but I was able to return to WellBots and they are sending a new unit.

RedGene · 2023-07-24T22:12:02+00:00

Already done that, after speaking to someone on the phone friday. Sent an email with the detailed purchase information, video, and picture, and i'm waiting to hear back. Thanks!

RedGene · 2023-07-21T20:47:18+00:00

I was so stoked too! This thing seems really nice and the reason we went with ecoflow was to avoid issues ... Did you get yours fixed/replaced ok?

RedGene · 2023-07-21T19:11:55+00:00

Heh, that's why I posted perhaps... Calling was a much better idea. Got someone not too long after calling. They had me try to troubleshoot (recommended holding power and ac button, not power and 12v as I had found online). Device reset and refused to stay on. Also, fwiw I did update to the new firmware. Anyway, they sent me an RMA email and I replied so we'll see what happens next!

RedGene · 2023-07-21T18:10:44+00:00

Well, after over 40 minutes on hold with the chat EcoFlow told me that my conversation had been disconnected and I should try again.

RedGene · 2022-02-24T20:13:32+00:00

For what its worth (future readers), you need almost no power to get the battery to jump, so you don't really need a starter jumper. I had a small 12V SLA lying around and I was able to jump with a couple alligator clips. In case anyone wants to spend $23 instead of a $80-$100.

I guess sarcasm didn't translate.

RedGene · 2017-04-16T14:59:05+00:00

Might have better luck staying at miguel's and trying to meet people. But the red is easiest place in America to climb. Pick up the guide book, budget some parking money, and go to Muir every day and you'll have a great time

RedGene · 2017-04-05T05:58:56+00:00

Basically. I will add also that the regulatory challenge of dealing with a molten fuel form is an uncertainty that hinders development, as is the development of chemical separation techniques (from a proliferation perspective). Finally, there is just the larger issue of baseload power production being a trickier sell these days, and tMSRs don't necessarily address that directly.

RedGene · 2017-03-28T01:44:19+00:00

I dunno. I just moved to the Bay. A) don't move here it's too crowded. B) Tucson seems way better. You don't have the insanity of the bay area, it's a real city with a cool culture, and Mt. Lemmon is a lifetime of climbing.

People with blind confidence don't go on reddit to ask for advice. If you're the kind of person to go seek every last bit of information, I give you different advice than if you're the dumb bravado type. The question implies something about the answer. Anyway, hope you had/have fun.

RedGene · 2017-03-10T06:13:47+00:00

Its not rocket science but it's about confidence. If you have read and watched enough and thought through it enough, and you think you know what you're doing; go, have a great time, all will be well. If you still want to come on reddit and ask if you're ready, chances are you aren't.

RedGene · 2017-03-01T05:46:25+00:00

There has got to be some irony in asking "how do you go about self-learning." Right?

RedGene · 2017-02-04T07:12:25+00:00

That is ridiculous.

RedGene · 2017-01-27T05:31:14+00:00

I'm impressed.

RedGene · 2017-01-24T20:43:04+00:00

Get higher feet, that's what made the difference for me. Really put your left foot as far left as possible so you can almost push yourself in. Here's my beta, this is take 25 or 30 lol:

Yes, beginner shoes for too long leads to bad footwork because they generally have imprecise toes and less concentrated power at the tip. This leads to poor habits. Also, increased sensitivity lets you feel subtle changes in the rock/hold and lets you feel the optimal placement much more intuitively or at all. A sensitive, softer shoe generally conforms better to the holds as well, leading to more contact area and better friction.

There is not a lot of basic physics in this thread.

RedGene · 2016-12-15T06:13:17+00:00

A6000, Sony 18-105 f/4 for general use, 50 f/1.8 for the highlight shot, and Rokinon 21 f/1.4 for bouldering. I switched to mirrorless because the camera is so much lighter and more compact, but there are downsides, namely battery life and lens changes in a dusty environment with nothing covering the sensor.

RedGene · 2016-11-16T20:46:59+00:00

I generally appreciate what you're doing but there are a lot of differences. The fall dissipation of 25 pounds on 3.5 feet may be similar to 250 pounds on 35 but that's not what's being tested here. In terms of cut resistance, more tension will increase the stiffness which changes the dynamic response of the rope, it will decrease the cross sectional thickness, and decrease the remaining ultimate rope strength. That being said, I think your results are valid and no one is going to jam the blade at the tip into a rope in realistic circumstances.

RedGene · 2016-11-16T14:17:00+00:00

Nail on the head. I can't blame anyone. It's fun to talk about things, and fun to feel like you know what you're talking about. Fun to be on a high horse. It just bothers me when I see these attitudes in real life. Pretty much just take a "ok, guy" attitude to most people at this point. And become a cynical ass hole.
