StormHarvester wants the sewer alarm to mean something
A Belfast software company is teaching wastewater utilities to spot trouble before sewage escapes. Its most useful trick may be knowing when a rising water level is just rain.
Terranova
Terranova is a Berkeley-born climate-tech and robotics startup building car-sized autonomous robots that inject a wood-waste slurry deep underground to lift flood-prone land out of harm's way - no seawalls, no surface disruption. A single 'mothership' coordinating three injection rovers can raise about one acre by one foot per day, while the buried biomass becomes a durable carbon sink that can be sold as carbon credits. Founded by UC Berkeley mechanical engineer Laurence Allen to save his hometown of San Rafael, California, the company raised a $7M seed round in November 2025 and plans its first San Rafael pilots in 2026.
