How Solid-State Batteries Actually Work (2026 Update)
How solid-state batteries actually work — sulfide vs oxide electrolytes, lithium-metal anodes, dendrite physics, and where the 2026 cells really land.
How Heat Pumps Actually Work (and Why They Beat 100%)
How heat pumps actually work, explained — the refrigeration cycle, why COP can exceed 100% efficiency, cold-climate limits, and the real physics.
How Lithium-Ion Batteries Work (and Why They Catch Fire)
How lithium-ion batteries work, explained — ions, cathodes, anodes, the SEI layer, and the chemistry of thermal runaway that makes them catch fire.
