What it should say is, 4 acquisitions that no one will have ever heard of and have no revenue. That will couple with the nothingness that has been delivered so far. Just smoke to cover the eventual prodding investors of more money.
4 companies appear to be part of Al Solaroli's businesses, the first of which has been already on DB's acq'tn list for many months: Combustion Engine Technology, renamed "CET Corp.". All are related to engine/car/marine, esp. racing or performance-oriented.
Solaroli patented an "adiabatic engine technology", sometimes described as a kind of turbocharging, in 2001, when he had a race car (Porche) performance tuning shop in Toronto, Canada. He subsequently set up shop in Jacksonville, FL. http://www.lastturnclub.com has pages on Solaroli and his businesses
