A new method developed by Northwestern University uses electrical currents to solidify marine sand, creating durable, rock-like structures that could replace costly traditional coastal defenses like sea walls.
Researchers from Northwestern University have demonstrated that a zap of electricity can strengthen a marine coastline for generations, mitigating the rising threat of erosion in the face of rising sea levels and climate change.
In their study, recently published in Communications Earth and the Environment, the researchers took inspiration from clams, mussels, and other shell-dwelling sea life, which use dissolved minerals in seawater to build their shells. Similarly, the researchers leveraged the same naturally occurring, dissolved minerals to form a natural cement between sea-soaked grains of sand. But, instead of using metabolic energy like mollusks do, the researchers used electrical energy to spur the chemical reaction.

So no homes in Florida :p
Here is a video of the Flagler Beach Restoration project that just completed. After Nicole and Ian, Flagler Beach lost about 100 - 140 feet of beach. Now restored.

marine sand comes and goes it’s natural
There will be massive clampedes away from the shorelines worlwide.
Great, now the beaches will be just like concrete in the cities that everyone is leaving to go to the beach.
It’s in all the movies, so it must be true! Would Kevin Kostner lie?
Wow! This is brilliant.
Who’s shelling out for this?

CLAMS GOT LEGS!!!
The most recent data from NASA shows a decline in sea level.
Inconvenient: NASA shows global sea level…pausing, instead of rising
Ice 9 anyone?
That proves we’re heading into a new ice age! Haaaaalp! We all gonna die!
Article lost all credibility for me when author went to rising sea levels and climate change…pureBS💯!coast lines change over time…always have, always will…take away…don’t build a sand castle at the ocean edge…maybe the electro hardening is a thing…won’t stop coastal changes…
“Unintended consequences...Think of all the New Yorkers going to Florida and being pissed that they can’t stick their umbrellas in the beach sand.”
Have you ever been to the beach? Down here in Florida we don’t stick umbrellas in the water.
For keeping the beaches in Florida safe?
Bring it!
I just bought a snowblower. :)
People have tried to protect coastlines with rock-like immovable solids for thousands of years. Some, like bay protecting embankments made of stone, work well for protecting the bay, but they also shift sedimentation patterns. More sedimentation upcurrent, sediment erosion (and potentially increased) down current.
The erosion of coastal structures is like putting logs on the side of a tank. The logs are sacrificial, and because they're soft they absorb the impact of anti-tank weapons. Even though sediments are composed of small particles, the friction between particles caused by ocean waves absorbs some of the energy of the ocean wave. Additionally, the sedimentary barrier structures shift over time in response to the wave forces on them. All of this movement reduces wave energy when it finally impacts the shore.
Hardening the coast in front of land structures eliminates the reduction in energy caused by friction between particles and eliminates shifts in sediments over time. it is likely that this action would cause more damage over time than doing nothing, and definitely a lot more damage over time compared to withdrawing insurance subsidies for coastal construction.

Since then your 2017 value of 85 mm has increased to 105!
