A new type of diverging nozzle is used to convert the energy of wind and subsurface ocean current into electrical energy. The nozzle is of either spherical or teardrop shape with a small hole in the surface facing the fluid stream. The fluid is made to exit through the surface where the widest diameter of the shape is. The fluid is drawn out by the Bernouilli Effect into the passing fluid stream. As the fluid is accelerated through the small hole the fluid in a tube whose first entrance is near the small hole has its pressure reduced. The tube's second entrance is an inlet tube to a Bourdon Tube. The flexing of the Bourdon tube is made to operate an electric generator through certain gearing. As long as there is a pressure difference between the fluid within the tube and the atmosphere then pressure within the Bourdon Tube can be alternated by valves so electric power output is maintained. Offshore, no moving parts are employed in the invention. The invention is also applied to recover energy needed to rotate a wheel, which may be a gear. Instead of a Bourdon tube a secondary turbine is used.

A gas analyzer includes a detector section including a detector, a source section including a light source, and a support structure coupling the detector section with the source section and forming a flow channel defining an optical path measuring region. The gas analyzer also includes an air flow device configured to pull air through the flow channel from an intake region in the support structure to an exhaust region. Sampling is done by pulling air into the sampling cell via an intake opening or tube of wide diameter and short to medium at very fast flow rates (e.g., 10-3000 lpm or more) enabling rapid gas sampling. Fast flow rates enable the use of large volume cell for rapid gas sampling, which in turn, enables rapid measurements of many low-concentration trace gases and sticky / reactive gases (e.g., methane, ammonia, isotopes of CO2, H2O, nitrous oxide, etc.).
