Indonesian Designer's Plan To Restore Ice Sheets Using Fleets Of Icemaking Submarines . . .

. . . is, indeed, the Stupidest Fucking Thing I've Ever Heard. Even by Techno-Cornucopian standards, it's the Stupidest Fucking Thing I've Ever Heard.

Now, designers in Indonesia have offered up what may be the most audacious plan yet: they propose building ice-making submarines that would ply polar waters and pop out icebergs to replace melting floes. “Sea level rise due to melting ice should not only be responded [to] with defensive solutions,” the designers of the submersible iceberg factory said in an animated video describing the vessel, which took second place in a recent design competition held by the Association of Siamese Architects.

The video shows the proposed submarine dipping slowly beneath the ocean surface to allow seawater to fill its large hexagonal well. When the vessel surfaces, an onboard desalination system removes the salt from the water and a “giant freezing machine” and chilly ambient temperatures freeze the fresh water to create the six-sided bergs. These float away when the vessel resubmerges and starts the process all over again.
A fleet of the ice-making subs, operating continuously, could create enough of the 25-meter-wide “ice babies” to make a larger ice sheet, according to the designers. Faris Rajak Kotahatuhaha, an architect in Jakarta and the leader of the project, said he sees the design as a complement to ongoing efforts to curb emissions.

“To stop global warming, of course we still have to reduce carbon emissions throughout the world,” he said in a message, adding that he advocated a two-pronged approach to curbing climate change: reduce carbon emissions on one hand and rebuild lost ice on the other.

Experts praised the designers’ vision but cast doubt on the project’s feasibility.
“It’s like trying to save the sand castle you built at the beach using a dixie cup as the tide comes in,” Michael Mann, a professor of atmospheric sciences at Penn State, said of the iceberg-making proposal.

Ummmm ... if you chill salt water, the ice separates out and floats to the top ... eppur_se_muova Aug 2019 #3

... thus accomplishing desalinization. If the designers didn't even know that, I have to doubt how well this design was thought out. No explanation where all that energy's coming from, at least ?
