One benefit to living close to the coast is the offshore breeze if you are on the West Coast, and the cool air the ocean provides if you live on the East Coast.
However, sometimes it gets quite hot in these coastal cities.
And since 50% of our US population lives close to the coastlines, when it is hot they use an excessive amount of electricity and energy to keep their homes, government agencies, schools, nonprofits and businesses cool.
However, there is really no need for cities that are close to the coastline to be using excess amounts of energy.
Using a simple trick of physics we can run pipelines down to the ocean floor, where the water is very cold.
This cold water will keep the pipes cool and if we allow air to flow through the pipes, and then run those pipes up into the city we can have all the cool air we could possibly ever want, without using any ongoing energy once it's built.
There are two ways this can occur, we can use the massive pipes to blow air into the city itself, thus, also mitigating some of the urban heat, and cooling all the air within the city.
Or we can allow people to connect to the pipelines, and allow them to go straight into the main buildings such as hotels, schools, libraries, and large homes.
If they want the cool air within the building all they have to do is open up their outlet pipe.
Although this might sound like a novel idea, it really isn't.
In fact, there is writing that in Babylonian times they used a similar process by digging holes underground and allowing openings which could be covered inside the homes.
They air blew through underneath where the temperature was 55-degrees and guess what? They had free air-conditioning nearly 4000 years ago, so what's our problem? Please consider this.
