Well Lucid Energy / water company is generating electricity from something that was not being used to generate electricity before.
This is NOT usually called "ENERGY HARVESTING", but it is close.
Energy Harvesting is getting little bits (or big bits) of energy from sources normally not used for that purpose.
NOW.
If we KEEP DOING THIS, continuing to develop technologies that get power from places that were ignored before, the total amount of energy from ENERGY HARVESTING will eventually be enough to take over from our usual sources like "THE GRID," or "BATTERIES."
ALSO,
I can see a future where we develop POWER CONSUMING devices that use very little power, so we may move to a society where stuff is sort of "POWERED" by nothing.
SORT OF.
Things that could be powered by "NOTHING:
- CELL PHONES
- LIGHTS
- TV'S
- RADIO'S
- COMPUTERS
Power generating devices whose extra power is being "THROWN AWAY:"
- CAR ENGINES (HEAT)
- CAR WHEELS
- CAR WIND (MERCEDES DOES w PAINT)
- CAR SOLAR
- RADIO WAVES
- ALL OTHER STUFF FLOATING THRU THE AIR
- BICYCLES
- VIBRATIONS
- PUSH BUTTONS
- AIR FLOW
- AMBIENT LIGHT
- NOISE
- HEEL STRIKE
- TEMPERATURE VARIATION
All of these sources of power usually all go untapped.
I'll bet right now somebody out there has a good sounding car stereo that only uses about 10 watts.
GO "ENERGY HARVESTING SOURCES"
