Tech firms are racing to develop robot assistants that can take over our dreaded household chores. But teaching machines to perform these deceptively simple tasks is tedious. They need to observe the actions thousands, sometimes millions of times. And there's a cottage industry springing up to provide this training. Marketplace’s Meghan McCarty Carino spoke with Ayanna Howard, roboticist and dean of Ohio State University’s college of engineering, to learn more.

Are there enough workers to build geothermal energy networks?
Combatting climate change will likely require a multi-pronged approach to renewable energy generation. After all, it's not sunny or windy everywhere all the time. Geothermal energy, which harnesses the natural heat generated by the earth, can significantly shrink the carbon footprint of heating and cooling buildings. Those systems are currently just a small part of the HVAC market. But the Department of Energy wants to accelerate production by 10% a year. Rae Solomon at KUNC in Northern Colorado reports on how one geothermal project in the municipality of Hayden is progressing.

The old technique that could power future nuclear reactors
Some AI companies are turning to nuclear power to meet demand for electricity. But traditional nuclear plants can take decades to bring online. Now some tech companies are partnering with startups trying to build small, modular nuclear reactors, designed with speed in mind. One such company, Kairos, has a deal with Google to build a fleet of modular reactors. To do so, it’s relying on a technique first developed in the mid-20th century: molten-salt cooling.

Chocolate's high tech and climate-friendly pivot
Extreme weather caused by climate change is affecting agriculture and raising the cost of foods like coffee, olive oil and chocolate. Cocoa prices have been hitting record highs due to extreme rainfall, drought and heat. And some experts say most of the land used for cocoa production won’t be usable in the future. Marketplace’s Amy Scott, host of our podcast "How We Survive," explores a new way tech entrepreneurs are making chocolate so that we can keep enjoying it for years to come.
