Talk:Flow battery

Would love to find the time to compare to a generator using methane and oxygen for long term storage of energy, or compressed air, or night/day thermal difference.

the generator is more interesting if you can use the waste heat, and is not too difficult to adapt, although you wouldn't have nitrogen involved in the explosion so definitively a big changes there. Worked on a mining site in Northern Canada where they had 5 large (4-5 MW) gensets that provided both power and heating for the mine on a permafrost area (Raglan). Very Martian in many ways.

Aluminum air is interesting, in particular if we use the new carbon free process for aluminum production. Would take a lot of development though. https://en.wikipedia.org/wiki/Aluminium%E2%80%93air_battery

Carbon free aluminum may be a requirement for Mars anyway, in particular if much of the carbon goes into methane for vehicle fuel or into the Life support system.

Rick: Hi Michel, why not put these points in pages that people will see?

Testing the use of the discussion page. Is it better to just write stuff out and then change it, or discuss it beforehand? TBH, I'm also enjoying the chat part. It gest a bit tiresome, just putting stuff out and getting no feedback.

Rick: Up to you. Maybe put up the stuff that is inarguable, and chat about stuff you are less sure how to approach? Warm regards, Rick.
