# Electronic – Free-as-in-beer power from neutral and ground

acenergy

I live in a house where each socket has 3 connections,:

1. hot (phase)
2. neutral
3. ground

Where:

• The voltage between hot and neutral is about 220V AC.
• The voltage between ground and neutral is about 2-3V AC.

Can I use those 2-3V as a 'free' (not paying for it) power source?
Do you know any project using them?
