RE: [GBlist] California look to the Ocean! - for District Cooling



And the other thing is: you still need a "cool delivery system" which is what the pumps and compressors and fans of a typical HVAC system are. So even if you can use the big Pacific heat sink without adverse effect, you still use electricity in the delivery of the "cool." So the real issue is not whether you ground source, air source, or ocean source the heat sink but how can you redesign or eliminate the air conditioning hardware. Am  I wrong?

That pesky Newton guy again: in this situation, what would happen to the waste heat? If you use cool water to cool spaces, you'll end up with hot water. Would there be a concern with algae blooms and other waste heat concerns as you pump all the hot water back into the ocean? Would that continue to warm the oceans? Or am I being naive? I know the sheer volume of the oceans could absorb a few gigaunits of heat energy, but could it absorb, say, even half of California's waste heat without a noticeable change in patterns or currents? Anyone want to try numbers? (Notme!)

 Limitless offshore energy - ocean water district cooling
- the California clean energy solution?

Building cooling with electricity and air-conditioning should be outlawed.  
 
All we need to do to have all the equivalent benefit as air-conditioning is to pump the  [ocean's] cooling water to the buildings.
