The story is about a scientist who creates rings of various sizes that allow energy to be transmitted through them. He starts with small 1 inch size ones and ends up making some very massive sized ones. He sells them and makes lots of money.

There is an author "Laurence Dahners" on amazon that has a series which eventually includes gates like these. The stories are available on Kindle Unlimited, if you subscribe.
