1. A startup called Terranova is proposing a solution for cities sinking due to subsidence and sea-level rise, such as San Rafael in California. They aim to lift the city using robots that inject a slurry of wood waste into the ground.
2. Terranova's approach is said to be cheaper than traditional methods like seawalls, with San Rafael quoted $92 million for lifting 240 acres four feet. The startup recently raised $7 million in funding.
3. The process involves using a robotic injection device to deliver the wood slurry into the ground, which is managed by software that Terranova has developed. The company claims their method could help reduce the risk of flooding and potentially even aid in earthquake resilience.
