A single large AI data center now consumes as much electricity as a city of 80,000 people. Vinod Khosla, the billionaire venture capitalist behind Sun Microsystems, thinks the answer isn’t fixing the grid. It’s bypassing it entirely.
Khosla has been backing Mainspring Energy for over a decade, pouring money into the company’s linear generator technology, which produces power on-site using a flameless chemical reaction. The pitch is simple: if the grid can’t get power to your data center fast enough, generate it yourself.
The grid bottleneck is staggering
More than 2,600 gigawatts of proposed energy projects are currently waiting in interconnection queues to plug into the grid. The grid’s total installed capacity is less than half that number. In English: there’s more than twice as much demand waiting in line as the entire system can currently handle.
Mainspring’s solution sidesteps the queue altogether. Its linear generators can be deployed on-site at data centers, running on a flexible fuel mix that includes natural gas, hydrogen, ammonia, and biogas. No waiting for utility approvals. No multi-year construction timelines for transmission lines.
