Wind turbines 'could use blades as giant batteries' (rechargenews.com)

Two parts of this make no sense.

1. If energy storage on-turbine was important, you could fill the tower (rather than blades) with a much better storage system.. lithium ion, gravity device, molten salt, etc. No complicated power transfer between turbine and blades required.

2. Turbine repair people talk about how regularly damaged the blades get, how they have to be locked/serviced/patched in place, or worst case the blade fully replaced. Surely this increases build/repair costs, and the risk to those repair people.

There's no discussion of what the energy density of the product is (nor on the direct website https://sinonus.com/)
