They offered improved fuel efficiency of 3 to 4% but at a 15% higher initial cost with 30% less tread life. With fuel prices at $1.50 per gallon, the math didn’t add up.

It’s claimed the unified diode equation for thin-film PV provides insights into the mechanisms driving limiting charge collection and power-conversion efficiency in low-mobility PV devices.

The piston in this quantum engine is the strength of inter-atomic interactions in the gas. To move the piston, Nautiyal’s scheme calls for abruptly increasing this interaction strength during the ...
