Breaking the Ice

12/30/2024 7:03 AM

How difficult would it be to break an iceberg into smaller manageable pieces? Would conventional explosives be effective, or would the ice simply absorb the heat of the explosion and be muffled to nothing but the power of flatulence? I read about an aircraft carrier(prototype, scale model) made basically of ice and wood pulp(pykrete) that was supposedly explosive proof due to the effect of ice on explosives and the triple phases of water absorbing the heat. it was never launched because of other difficulties, but the idea seems sound on the face of it.

An iceberg would be worth billions of dollars as fresh water if a way to harvest them is discovered.

Any ideas?

You might be able to design a hydrogen lift craft to transport your large ice cubes, this would avoid the most obvious problem of rapid melting, ocean transport vs high altitude travel below freezing...somewhere around 15k feet maybe...

No need to blow anything up, just stand off the location of a glacier calving site and pick the ones that are the right size....

Yes I can see it all now, thousands of these lighter than air transport vehicles forming great sky trains across the globe...unmanned autonomous sustainable powered by hydrogen produced by solar and wind facilities on the ground...diverting water and other cargo from place to place navigating the world over via wind currents and hydrogen powered engines...

Hey! They have a Schlumberger truck in the picture in #1. I worked as a well logging engineer in those for seven years.

Maybe you could just use one of these giant sea cranes to just lift the iceberg out of the water and place it on a large high powered barges...then you could have a water collection system built in to catch the ice melt, and pump it ashore as the ice melts..

Need giant claws for picking up iceberg pieces....Barges with perhaps 500,000 m3 cargo capacity, (1 cubic meter of water = about 1 ton weight)...perhaps 50 barges...tugboats can steer the iceberg pieces to cranes for loading....maybe 4 cranes...giant saw for cutting up larger pieces...

Yeah it's doable...

Fresh water costs by desalination....

"Energy is just one part of the full cost; estimates are around one-third. Multiply by three, and we get around $1.50 per m3. In states like California, the energy cost might be $0.50 higher, bringing the total to $2."...

https://www.sustainabilitybynumbers.com/p/how-much-energy-does-desalinisation

I think this is the cheapest option at this time...

It has to compete with seawater desalination by reverse osmosis, which costs around 4kWh/tonne delivered, and which isn't particularly difficult.
