Ocean Thermal Energy Conversion Projects must be initiated NOW

Ocean Thermal Energy represents the largest form of continuous, consistent energy available to the "Industrial Human" (Society Globally). Not Wind, Wave, Conventional Solar (Panels) or Biomass can compete. Here I show what our troubles are, we either get GREEN like its WW Five or we DIE...right now we consume at a rate of 15 Tera Watts (15 Million Million Joules per Second or 15 Million MegaWatt-hrs per hour, naturally).

You do the Math, I show you how.

Aloha!
Be back next week!

then, what is the central theme of your video?

if you dont know how much power you can obtain from an OTEC plant, how do you know how many plants we need?

honestly, dont take this personal, im all for OTEC, i live in Puerto Rico and we have Ideal conditions for OTEC. but just because you put some equations together doesnt mean it works. just because the ocean holds a tremendous renewable clean energy source it means OTEC will work as you describe here. you haveto substantiate your alegations.

I accidently hit remove button on comment you made "talk to a mech or elec engineer you trust"... I am both, and Master's Engr in OTEC!

Thanks for the feedback...

BTW, dont like your tone......hmmmm

.....blocked!

dude. Power = Mass flow rate*delta T*Cp is not the power that the system will provide. that the power source. you need to multiply that by the efficiency of your system (10% at most??) to get the power supplied by the system. unless your OTEC plant is 100% efficient. second, there are 2 water flows, hot and cold water. im not sure if the power that enters the system (which is the one you are using here) is simply p=Mdot*Cp*delta T

Pipepr,

Your comment does not address the central theme of this video, the point.

Essentially, under the best conditions (say 100% efficiency), we are way behind the "power curve" of switching to alternatives.

For purposes of this video, the simplicity of equations is sufficient and valid!

[UnderseaCaveman]

If you want a little more techy feedback,

steam power would be as described, then attenuate by turbine efficiency, finally take-away system internal power consumption (ie, pump work), and that should leave "Net Power".

But, again, under best case, we are "dead"!

[UnderseaCaveman]

to answer your question on second stream, the cold water, that would be accounted for in both Delta-T, and later in take-away from gross power due to pumping power required (of course same can be said of warm water, though, it maybe considered flowing "downstream", from atmospress to near vacuum, may not need a pump).

@UnderseaCaveman But I saw than hand write "each making 1MW each hour". You only have to say "each makes (generates) 1 MW".-- In 1 hour they would produce 1MWHr of Energy. But if I might also comment about the concept. It might be best (best witha capital B that is) to think about the human population. If over-night it doubles, & it has in just my life, then YOU would still be getting a little hysterical about "we're all going to DIE" when that, IN PART would be the best natural solution.

The Big Island Geothermal project basically sent water down pipes to be heated by the volcanic heat. For some reason, there was steam dump line to atmosphere. This emitted sulfur gasses and was extremely loud. I think it is a case of bad design rather than bad concept. I think they at least fixed or reduced those problems. Recommend google "Puna Geothermal Venture" for details.
