# $5 stock solving AI's biggest problem

This $5 AI infrastructure stock could have massive upside if its technology catches on. AirJoule Technologies is developing a system that uses excess heat from data centers to pull ultra-pure water from the air. That water can then be reused for cooling, potentially helping solve two of AI’s biggest infrastructure problems at once: heat and water demand. The company is still pre-revenue and carries plenty of risk, but a recent design lock-in for its industrial-scale Prime system could be an important step toward commercialization. Here’s why some investors believe this beaten-down stock could have major gains ahead.
