Inspired by the Asus ROG Zephyrus Duo, Compal's BreezePro concept seeks to improve air cooling efficiency for laptops with a slanting keyboard design.

This is an interesting variation on this concept. I'd like to mention the similaries to the Asus S17, both the 2021 version with the rising keyboard and the earlier (2019?) With the lowering base.
