Your brain generates enough electricity to power a small LED

Neurons fire tiny electrical signals. Summed together, brain activity is often pegged near 20 watts — roughly a dim LED’s draw.

That modest wattage runs perception, memory, and planning; efficiency is the real flex, not megawatts.

A low-power supercomputer in bone. Sip glucose carefully — the light stays on only while the fuel does.
