I believe no blind spot, which is the place where all the nerves bundle together and pass through the sensing layer, leaving a hole in our vision (the brain works hard to hide this hole from our perception, but it’s still there and can cause accidents) Also maybe better vision in general?

For context: jk Rowling

If evaporative cooling is the only solution then the market will adjust to the new cost by moving power generation towards the coasts or just increase the price, if there are other solutions they’ll become the economically more viable. Either way more water is conserved and you can always balance the cost benefit by adjusting the fine/tax to find a good balance.
