“ To their surprise, the engineers found the chain drive had an energy efficiency score of 98.6 percent, meaning less than 2 percent of the power used to turn the front sprocket was lost as heat, ” the report said.
„ Oma üllatuseks leidsid insenerid, et kettülekande energiasäästlikus oli 98,6 protsenti, mis tähendab, et vähem kui 2 protsenti eesmise ketiratta keeramise jõust muutus soojusenergiaks, ” ütles raport.
