Sacrificial anode, does it work? Tests and results in the video.

Today we are going to do an incredible test, we tested a cathodic protection with carbon steel and zinc, and you will be surprised by the result. The test lasted 30 days and we have already achieved good results.
Cathodic protection
From Wikipedia, the free encyclopedia.
Aluminum sacrificial anodes (light colored rectangular bars) mounted on a steel jacket structure
Cathodic Protection is a technique used to control corrosion of a metallic surface by making it the cathode of an electrochemical cell.[1] A simple method of shielding connects the metal to be shielded to a more easily corrosive "sacrifice metal" to act as the anode. The sacrificial metal is then corroded in place of the metal to be protected. For structures such as long pipelines where passive galvanic cathodic protection is not adequate, an external DC electrical power source is used to provide sufficient current.
Cathodic protection systems protect a wide range of metallic structures in various environments. Common applications are: steel pipes for water or fuel and steel tanks, such as domestic water heaters; steel pier pillars; hulls of ships and boats; offshore oil platforms and metal jackets for onshore oil wells; offshore wind foundations and metallic reinforcement bars in buildings and concrete structures. Another common application is in galvanized steel, where a sacrificial zinc coating on steel parts protects them from rust.
Cathodic protection can, in some cases, prevent stress corrosion fatigue.
Story
Cathodic protection was first described by Sir Humphry Davy in a series of papers presented to the royal society in London in 1824. The first application was to HMS Samarang in 1824. Iron sacrificial anodes attached to the copper hull placed below the line water dramatically reduced the corrosion rate of copper. However, a side effect of cathodic protection was to increase marine growth. Copper, when in the process of corrosion, releases copper ions that have an antifouling effect. As excess marine growth affected the ship's performance, the Royal Navy decided it was better to allow the copper to corrode and have the benefit of reduced marine growth, so that cathodic protection was no longer used.

Polarization of the target structure is caused by the flow of electrons flowing from the anode to the cathode, so the two metals must have good electrical contact. The driving force for the cathodic protection current is the difference in electrode potential between the anode and cathode.
Galvanic or sacrificial anodes are made in various shapes and sizes using zinc, magnesium and aluminum alloys. ASTM International publishes standards on the composition and fabrication of galvanic anodes.
