Building new cooling towers would drive our costs up as we would have to pay for the capex of the towers in addition to the rest of the process. For now, we are trying to keep everything as low-cost as possible. Cooling towers typically run outside since they sometimes have water evaporating out the top of them, but even if cooling towers were inside, this would still be a great solution. CO2 concentrations indoors are sometimes even higher than the ones outdoors, which may allow for even higher carbon capture amounts than outdoor systems would.
