Paths to the Energy Miracles
Published in H. B. Glushakow, Energy Miracles, 2022
Tesla went to Colorado Springs between 1899 and 1900 to pursue this idea. He had a friend, a director of the Colorado Springs electric company, who had offered him unlimited power for the experiments he had in mind. Tesla built a tower outside of town and went to work. By that time, many experimenters had wirelessly sent small packets of energy out to small distances. The most successful of them, Marconi, had transmitted radio waves out to a distance of 2 miles. In this regard, Tesla was way ahead, having already sent radio waves out to a distance of 30 miles. He had also demonstrated a radio-controlled boat in Madison Square Garden in 1897. Control of the direction, speed, and lights was accomplished with the “tuning” of radio signal frequencies. Tesla knew more about this process than anyone on Earth and in fact obtained the first patents on it. But he was not interested in transmitting radio waves. He thought they were wasteful. He was interested in long-distance wireless distribution of electricity.
Discharge measurements field validation using remote-controlled boat with ADCP
Published in Journal of Applied Water Engineering and Research, 2023
Daniel Iozzi Sperandelli, Tiago Zenker Gireli
The first mention of an ADCP on a remote-controlled boat is found in Simpson (2001). The author reports the existence of a radio-controlled boat 12 feet long, powered by a combustion engine, containing an acoustic Doppler current profiler (ADCP), developed by the USGS (United States Geological Survey) to perform discharge measurements during floods, avoiding the risk of an accident with workers. No further details are given, such as years of use, number of measurements taken, quality of collected data and, mainly, whether the solution was considered successful.
