I feel like cold chain is a problem set better addressed by material science, than the en vogue "electrify everything" approach Between better sealing systems

I feel like cold chain is a problem set better addressed by material science, than the en vogue "electrify everything" approach Between better sealing systems and phase change materials I feel like there's more than a few gems to be had. Popping a battery on a Pelletier cell or some conventional (but miniature) Carnot cycle contraption just doesn't make sense!
