  • SolarMantle, which creates solar paneling systems that provide passive cooling for people and equipment, partnered with the FIFA World Cup Houston Host Committee to install solar paneling on restrooms at Midtown Park and on tents at the FIFA Fan Festival in EaDo, with the panels expected to lower temperatures in a shaded area by more than 40 degrees on a sunny day.
