水力发电技术
When a person’s hand reaches for the
faucet, water automatically sprays out.
There is a close-up shot of the internal
structure of this functional part. When
water is supplied, the force of the water
turns the impeller, generating
electricity. The generated electricity is
stored and then used for sensor detection
and opening/closing the solenoid valve. No
power supply is required, making this an
environmentally friendly function.
