Hi everybody, I'm the founder of Prometheus. Happy to answer any questions!

While I generally agree with some of the comments about the usability/accessibility/load times, this is a visually amazing website and is a super impressive piece of design. Ran really nicely on my admittedly over-spec'ed laptop.

(I say this as someone that would be happy if every website on the Internet was just written in plain HTML with no CSS and just a few images.)

Thanks! Really appreciate the positive comment :)

My desktop is overly low end. Scrolling is a bit laggy but the presentation was interesting: Change nothing.

More a bit of feedback then question.

You are obviously aware of the issues with the site. I like the vision and how you've laid it out, but I felt you were missing a trick with design a bit.

You lay out the "for centuries the way.." really well, and it's fun. I feel like I'm in Mad Max. But then, you introduce your technology, and everything is still desert. I don't feel like you've "changed the world" because your tech is so great.

Also, for LOTS of people (as you can see in the comments) this sort of web experience doesn't work when they want to dig into real details, or want to feel like they aren't watching a movie. They want it to feel real, so I'd recommend a place they can go with a simple layout, almost whitepaper like description of what you're doing. Perhaps that exists, but I couldn't find it, and you even had a comment (more highly voted than yours) which has copied the text from your site, and pasted it here to be easy to read.

Just a few suggestions.

Thanks for the feedback. Working on the site and hope to have improvements in the next few months with improved tech explanations, clarity, and speed.

I'm curious if Prometheus has considered any options for permanent sequestration. Perhaps buying an old oil rig and pumping electro fuel back into it.

It's obviously hard to find an economic incentive to do this, but maybe carbon credits would make it possible.

How would that be better for the environment though?

Unless we have a way to electrify all planes (we don't currently), this is the next best thing. I think the key is to ensure biofuel never gets cheaper than regular fuel, to avoid incentivizing flying more.

If you sequester what you pull out in some old oil well, while American Airlines is pumping out from the next oil well, it has to be less effective (and thus release more CO2 in the process), than just you sending your oil from captured carbon directly to them.

It would make sense in that we need a net reduction in atmospheric carbon, and not 100% of carbon emissions come from burning fuel.

Though, I do see your point-- This only pencils out once you've captured 100% of the available fuels market, which is quite large.

What's the current density on the electrolyzers? Does the low concentration of CO2 impact it? What kind of air contactor do you plan to use?

I'm a big fan of what you are doing. If I weren't already working on fusion energy, this would be the technology I'd most like to work on. People forget that decarbonizing electricity is only 1/3 or 1/2 of the energy/fossil fuels problem. We need to find a way to turn massive amounts of renewable electricity into fuels and chemical feedstocks.
