From what I just found on Google using Lens and Gemini: It is a Windmill Palm (Trachycarpus fortunei), also known as the Chinese Windmill Palm or Chusan Palm. The fruits of the windmill palm (Trachycarpus fortunei) are technically edible, but they are generally not consumed as a food source due to their fibrous texture and neutral taste with a large pit. Most sources indicate they are not palatable for human consumption.

So technically, I guess you could eat them, but probably wouldn't taste very good.
