Science-Accepted “Free Energy” 3
Low Temp Micro ThermoElectric
• -->>continued: FREE ENERGY TYPES; increasing actively commercialized
exceptions, Micro Current Energy Harvesters:
• Often ROI comes at equivalent of when first time replacement of battery or fizzled
wire for sensors is required, especially in remote or difficult to reach locations.
Many devices combine multiple mechanics to maintain required electrical supply
level. Free energy harvesting micro devices are generally not frequently reported
in newspapers or energy saving publications due to micro electrical nature, but
products are available for very wide range of sensoring/actuating applications.
Some cases there is no differentiator to long lasting battery system(eg self
charging tire sensor for non-commercial vehicle). Many companies sell "Evaluation
Kit" to test out. Following 1-14 main methods are listed as general representative
energy scavenging methods.
1 # Low temperature dif.(1-20°C) Thermoelectric device(industrial type
generator version at p50-53): easily made as garage project with high
performance Seebeck effect parts(A Makosinski+) & commercialized for consumer
market prior to current industrial use micropower in 1990s and withdrawn(Citizen
Eco-Drive Thermo, Seiko Thermic), more recent consumable types(Fujitsu,
Yamaha had test products, Vodaphone: PowerPocket+), Latest consumer watch
market debut (Matrix Industries+). Can be woven into fabric(KAIST South
Korea+)(Gr Moriarty+), mass produceable by easy printing(AIST Japan+).
