Blade solidity

Blade solidity is how closely the blades are packed together on a wind turbine. Think of it like a pizza. If you have a small pizza with only a few pieces of pepperoni, it's not very solid. But if you have a big pizza with lots of pepperoni tightly packed together, it's very solid.

In a wind turbine, the blades are like the pepperoni and they need to be packed together tightly to capture more wind and generate more energy. However, if the blades are too close together, they can create turbulence and slow things down.

So, wind turbine engineers have to find the right balance of blade solidity to make sure they are capturing the maximum amount of wind without creating too much turbulence. It's kind of like making the perfect pizza with just the right amount of toppings.
