OK. I'll send it after this
what i'll give myself 15 more min before going back into my dank lab
the laboratory is a temple, because the chemist is a god.
well it has its perks
And here I am just writing up the "time's up" thing...
magnetron sputtering!
not all dank
yes, that would be correct
should get into that. sadly, the only thing in my shop that does not suck is the vacuum pump.
well @Dan Maloney is it ok if we go a little over if I promise to clean up?
@Thomas Shaddack well, I know a guy...
Absolutely fine! But I'll just say the official "Thanks!" and let the conversation wind down naturally.
okey
Need to work on Mg Al batteries for lower cost and material availability.
Thanks to Dave for stopping by today and to everyone for a great discussion!
it has been a pleasure. thanks for inviting me
As a comms-guy I feel like I should ask about any open-source BMS projects.
Thanks everyone!
Ahh..next time. Thank you.
You bet, I really enjoyed this one -- anytime I get to talk about plutonium is a happy time! Thanks for helping us wrap up the 2022 Hack Chat season with a bang!
Had a thought about the bidirectional buckboost. Change the architecture of e-vehicles. Have a small Li-titanate battery built in, as a low-temp tolerant high-current high-cycle tolerant primary source for the engines. Have a power bus from it to the bays with the buckboost nodes. Put anything into the bay - a conventional Li-ion battery, a hydrogen fuel cell, a turbine fed with dry-distilled waste plastic scavenged after the zombie apocalypse, a completely new emerging battery chemistry, or nothing if we conserve weight and do not need distance, and go.
@Tom Johnson not my ball of wax but I'll keep my ear out for the BMS stuff. Grateful folks are working on other pieces of the puzzle. I only have two hands
FYI, I'll be posting a transcript once things wrap up a bit, in case anyone needs a link or whatever
Mixing and matching power sources depending on the application is always a good thing to do. There are no one size fits all solutions
I guess we just need to keep charging on!
Same for stationary power. Have matching circuitry that can feed a battery bank, a hydrogen electrolyzer, whatever we got. Without having to plan for things in detail during initial build.
I haven't tried, but I would suspect some resistive heating of cold Li ion batteries might help them warm up faster. I'd be surprised if this wasn't used to some extent already, to the limits of what you could get away with without damaging things
meaning, the battery is more resistive when it's cold, so its internal resistance should warm it up a bit...
Have a big power plant made from smaller modules. If needed, break off modules and move them where they are needed more. If something fails, we degrade performance by the percentage of disabled units and continue on.
I saw somewhere a battery with built-in resistive heaters.
a nuclear reactor on every rooftop! What could possibly go wrong?
In every basement. Rooftops are for the backup generators in tsunami/flood areas.
One time we started our fuel cells up from -30C. it took a while but it worked
well, the sun itself is a nuclear reactor fed with a fossil fuel.
can't do that with nafion. ice crystals puncture the membrane
in long term, certainly not a renewable.
@Thomas Shaddack Interesting on the BB concept. As these things become more modularized and interchangable the application-space widens.
could we inhibit the formation of the crystals in some way? or make them form in a way that do not penetrate the membrane?
I say we kick the sun running out of fuel down to future generations
Carbon is a stellar nuclear waste product.
Intermediate. Iron is the final waste.
make it into diamond
Dyson Spheres!
@Tom Johnson my old company Ultracell really got into mixing and matching all kinds of modular portable power sources depending on need/availability
So white dwarfs are composed of diamond.
sure, diamond at 170 g/cc, sure
Could be handy for kinetic penetrators. Depleted uranium, eat your heart out!
'Diamond rain' falls on Saturn and Jupiter - BBC News
more accurate would be "falls *in* Saturn and Jupiter".
Old car batteries will be a plentiful resource, reusable for house power. An arrray of such units can give a megawatt or more in short term. Could be handy for DIY pulsed power fun and games.
OK kids I'm going to head into the lab to commit electrochemistry. Thanks for the conversation
Was GREAT to see you!
Ok I need to replace another aluminum take out pie plate electrode in my laptop battery cause the old one is dissolving away.
random thought. opensource potentiostats, and other electrochemistry gear.
for voltammetry and so.
yes I have baby designs. one quad op amp. Great for teaching
I'm off to cook a lasagna in an iron pan and store it with aluminum foil. Bye for now.
the i2c current-voltage sensors are great for such toying.
ina219, ina3221 and so on.
@Tom Johnson "I have backup applications for equipment sitting in unheated buildings." look at LTO batteries maybe?
Will look. Thanks.
@Tom Johnson sent you an email
@Tom Johnson "As a comms-guy I feel like I should ask about any open-source BMS projects." Yeah someone needs to release open Spec with example embedded library ready to run. it's someone on my to do list.
Something
@ILove Scotch also thanks for the conversation
Np which I could have asked more question, I dipped out eariler as had to pick up my kid.
