No the re-bar will rust in the ground when exposed to the ground dampness. This will cause the rod ground resistance to gradually increase. Approved ground rods are either copper clad or galvanized. In locations where it is impossible to drive a 10 foot rod into the ground the electrical code has approved ground plates that can be dug in and buried at two feet in depth. You want the resistance to be as low as possible on a grounding circuit. Alternatively, if that re-bar is part of the concrete foundation (Ufer ground) of the structure (and at least 20 feet long, 1/2" min. diameter) it is a perfectly acceptable grounding electrode.

Yes, a lightning rod mounted on a tall building can help protect the structure by providing a path for the lightning strike to safely reach the ground without causing damage. The rod will attract the lightning strike and conduct it harmlessly to the ground, reducing the risk of fire or structural damage. It is important for the lightning rod to be professionally installed and maintained to ensure its effectiveness.
An earth rod, also known as a grounding rod, is a metal rod that is buried in the ground to provide a safe path for electrical currents to dissipate in case of a fault. It helps prevent electrical shock and damage to electrical equipment by directing excess electricity safely into the ground.
On a North American electrical distribution system this is quite normal and natural. The neutral connection point in a distribution panel is connected to the ground rod via the ground wire. So in effect the ground rod and the neutral are one in the same.
A ground rod for a house is typically driven into the ground near the foundation of the house, close to the main electrical service entrance. It is driven vertically into the ground to help provide a path for electrical surges to safely dissipate into the ground, protecting the home from damage.
Any metal that will conduct electricity. Steel works fine, since it is strong. A ground rod driven into the ground and connected to the lightning rod with a wire or cable. The ground rod is usually copper clad (or plated) steel.
The lightning strikes the rod and the rod safely directs the lightning to the ground to keep the house safe.Otherwise,the lightning would discharge onto the roof and likely cause a fire.
The ground wire should come from the ground rod and to the main electrical panel grounding terminal.

Grounding is accomplished by connecting a heavy cable from the ground side of the antenna to a ground rod. A ground rod is typically a 4 - 8 foot copper plated steel rod driven into the ground as close as possible to the antenna, making the wire connection as short as possible. All equipment should also be grounded to a rod, not just the antenna.
An earth rod, also known as a grounding rod, is a metal rod that is buried in the ground to provide a safe path for electrical currents to dissipate in case of a fault. It helps prevent electrical shock and damage to electrical equipment by directing excess electricity safely into the ground.
Bentonite has an affinity for water. By packing Bentonite around the ground rod it increases the conductivity of the ground rod. Ground rods are not supposed to have a resistance above 5 ohms when compared to the utility's ground grid. Getting the ground rod into this resistance zone in bad soil conditions is aided by the use of Bentonite.
As long as the clamp is of an approved type only one is needed per ground rod.
A lightning rod is a metal rod or conductor mounted on a building or structure to protect it from lightning strikes. The rod helps to safely conduct the electrical charge from a lightning strike to the ground, reducing the risk of fire or other damage to the building.
On a North American electrical distribution system this is quite normal and natural. The neutral connection point in a distribution panel is connected to the ground rod via the ground wire. So in effect the ground rod and the neutral are one in the same.
