bits per second. Such a data rate is far more than possible with communications systems using

transmission cables.

The main objection potential investors had for my idea were the communications interruptions from

bad weather. It is true that during some heavy snow storms and thick fog conditions the reception of

the transmitted light signals could be blocked. But, overall I felt that people subscribing to such a

service could tolerate a few interruptions each year. In spite of my arguments, I was not able to find

any investors. So, It is hoped that someone reading this might someday consider the idea and make

it a commercial success.
