There are 56 reactors in France, they never went offline at the same time. It happened that half went offline but no more than that

Fyi you can get a stainless steel under sink RO system for less than 200usd on amazon, no plastic piping either.

Very different experience here, to the point I will not buy a VW again. Not a single OTA update since I bought it in October 2021, 3 recalls already and they don't even have the pa…

Do you have a source? I can't find anything about it

https://www.nextinpact.com/article/71103/gandi-fusionne-avec... Google translate it from french. Basically the new owners are known for not caring about customer service. Gandhi em…

Good question! I would say advances in numerical simulations, cheap renewable energy, and a lot of luck/perseverance (we would not have found this technology without spending 3 yea…

It is a combination of things. We hesitated a lot to do a crowdfunding but : - a corrosion issue nearly killed us and we had to "reboot" - our team was in full lockdown in France f…

at a mathematical conference :)

You are correct, even though your last sentence wasnt necessary... Please consider a use case where an industrial user install a thermal storage like this one https://www.kyotogrou…

I agree! I would love to see the carbon intensity of each product I buy or some kind of scale from A to F.

Stirling engines like ours can go at cryogenic temperatures too :) They are used to reliquify natural gas at LNG terminals, but we decided to focus on industrial heat for now. You …

We are building more than a heat pump, it is a novel stirling architecture, that is, a machine that converts electricity to heat, and heat to electricity. The idea is summarized on…

I can't go into details for confidentiality reasons but we published a paper last December on one of the simulation models : https://link.springer.com/chapter/10.1007/978-3-031-120…

We started in 2016 with just an idea, and we probably encountered every problem you can think of ! - hard to raise funds for large deeptech projects (thank you YC and Wefunder for …

we published a calculator if you would like to dig deeper! https://airthium.github.io/airthium.com-calculator/ The COP gets lower as the temperature difference increases as you can…

We are building the world's highest temperature heat pump. It can reach 1000℉, when other commercial heat pumps usually reach a maximum of 320 ℉. It is a big deal because factories…

I would be happy to have that. Most of the time it is 50 to 90kW at the 2 EA stations I use in Texas

Franck here, Airthium's cofounder (YC S17). Happy to answer all questions about our ultra high temperature industrial heat pump!

It says heat energy

Heat pumps extract additional heat from a "cold source" like ambiant air. They do output more heat than resistive heating.

not CAD but we built our own open source FEA tool. see https://tanatloc.com

How much GHG does the rocket emit?

We dont use refrigerant and it is a single HP with a 930F lift (so huge temperature difference between source and sink temperature). It is more than a heat pump, it is a new Stirli…

If you are into heat pumps, our team at Airthium (YC S17) is building an industrial heat pump able to reach 1000℉. Most HP are limited to 360℉ so it is a big deal in terms of indus…

if you are interested in mechanical contact, we developed a symmetrical algorithm (no master/slave) and can make it available for you on https://tanatloc.com
