An electrochemical system for efficiently harvesting low-grade heat energy [PDF]
Nature Communications, 2014 Efficient and low-cost thermal energy-harvesting systems are needed to utilize the tremendous low-grade heat sources. Although thermoelectric devices are attractive, its efficiency is limited by the relatively low figure-of-merit and low-temperature differential. An alternative approach is to explore thermodynamic cycles.

Heating Method of Low Grade Green Tea
Chagyo Kenkyu Hokoku (Tea Research Journal), 1975 The effects of heating conditions (hiire) on the qualities of low grade green tea were investigated employing a tea heating machine of drum heating type.As the results of sensory test, it was found that the heated tea produced the most favorable flavor when it was heated at 110-120°C of tea leaf temperature.
