Lochner, they made waves on one side with a spade and experimented all day in the family pond until he found that waves only exert their force to a relatively shallow depth,

The big challenge in the rough seas of the
English Channel was to create a breakwater to protect the concrete landings from the vicious waves and Robert Lochner was the man chosen by Churchill to lead a group of scientists known as
300:. The decision to go ahead was taken and full-scale trials of the floating breakwater started in April 1944. During the trial, an onshore gale produced heavy seas, but Robert's bombardons calmed the waves effectively.
