Xóchitl Guadalupe Cruz López, a teenage girl who invented a solar water heater from recycled materials, visited President Claudia Sheinbaum at the National Palace on Thursday to promote her invention and discuss ways to bring it to more households. The meeting, which was livestreamed on Sheinbaum’s official TikTok account, took place after content creator Alexis Omman shared a video asking Sheinbaum to take notice of Cruz’s work.
