High Temperature Feasibility

Discussions focus on the thermal plausibility of high temperatures like 300°C in an experimental apparatus or process, debating material limits, boiling points, superheating, and Celsius vs. Fahrenheit scales.

It's not clear that this is thermally possible.

davidhowlett Jan 13, 2021 View on HN

I think you mean above 80 degrees Celsius

garmaine Dec 19, 2020 View on HN

At higher temperatures, you mean.

burgerbrain Jan 19, 2011 View on HN

The article talks about it getting up to 300C. Regardless of how it works that is a little concerning.

Yes. The fuel gets much hotter than the container

cjbgkagh Sep 8, 2023 View on HN

Wouldn’t temperature difference be a problem?

ceejayoz Nov 10, 2023 View on HN

That would be well above boiling.

OldTimeCoffee Aug 5, 2021 View on HN

Sure, good luck with the vessel at that temp

philshem Feb 22, 2024 View on HN

Surely Fahrenheit, so as to not be above the boiling temperature of water.

As you can see, the apparatus didn't evaporate while working, so, probably, temperature is much lower.
