Ideally, they should be constructed of light weight materials like reinforced aluminum
The energy produced by turbine blades turning is typically mechanical energy. This mechanical energy is then converted into electrical energy through a generator connected to the turbine.
A wind turbine is a device that converts wind energy into electrical power. It consists of blades mounted on a rotor connected to a generator, which produces electricity as the blades spin in the wind. Wind turbines are typically used in wind farms to generate renewable energy.
A spinning turbine typically uses mechanical energy from a source such as wind, water, or steam to rotate its blades. This mechanical energy is then converted into electricity through a generator.

The word is "turbine".
Gas Turbine.
The current technology involved in flying cars can be traced very directly to avionics. The use of airplane engines in both jet, turbine and cylinder combustion with a variety of lift options. Some being of the traditional "wing" design and others sharing more in common with rotary blades. Lightweight materials are used in body construction to reduce the overall mass of the vehicles.
You may have mixed 'Lego blades' up with 'Lego Bionicle'.
A metal-cutting saw, such as a hacksaw or a bandsaw, is best for cutting metal due to their specialized blades and ability to handle the hardness of metal materials.

I think a good store that sells tree pruner saw blades are probably either Lowe's or Home Depot. They usually have the best selection available out of everybody.
Band saws are used for cutting curved or rounded shapes out of materials. There are different types of blades to cut a variety of materials. Make sure you wear eyewear when using this tool.
