Diphenhydramine (Benadryl) is the most common first-generation antihistamine found in OTC sleep aids, whether used alone or in combination with pain relievers, including acetaminophen (eg, Tylenol PM), ibuprofen (eg, Advil PM), and aspirin. Other sleep aids often contain the antihistamine doxylamine (eg, Unisom).
The output of a wind turbine depends on the turbine's size and the wind's speed through the rotor. An average onshore wind turbine with a capacity of 2.5â3 MW can produce more than 6 million kWh in a year â enough to supply 1,500 average EU households with electricity. An average offshore wind turbine of 3.6 MW can power more than 3,312 average EU households.
By the year 1908, the U.S. had a 72 windmills with a total capacity of 25 MW. By the onset of the 1st world war, the U.S. was producing 100,000 windmills for farm use purposes e.g. pumping water. USSR in 1931 developed a wind turbine at Yalta, which later gave way to the modern wind turbines.
