- Lenovo envisions data centers suspended above clouds to save land and energy
- Data Spas places servers near geothermal pools, which raises serious security concerns
- Underground bunkers offer protection and natural cooling for high-density computing, or maybe not
Lenovo has revealed a number of very unconventional concepts that imagine what the future data center infrastructure could look like.
The company argues that traditional data centers need to evolve to support businesses, as nearly half of IT business buyers admit their infrastructure does not meet energy requirements and carbon targets.
In response, Lenovo has proposed several unconventional designs, including one that places data centers almost literally among the clouds.
Data centers above the clouds
Each design showcases a different approach to powering massive CPU and AI workloads while considering energy efficiency and sustainability.
The most unusual of Lenovo’s designs is the “Floating Cloud”, a data center suspended between 20 and 30 kilometers above the earth’s surface.
At that altitude, it would operate solely on solar power, while using pressurized liquid cooling systems to manage heat.
The concept removes land restrictions but poses major security risks, as a structure floating above commercial airspace would be difficult to protect and vulnerable to attack.
Lenovo also envisions what it calls a “Data Spa,” a geothermally powered data center built into a natural landscape such as a valley or hot spring.
Images of the concept show people walking through pools of water just meters away from server racks.
The design suggests a seamless integration between nature and technology, but it raises serious safety and security concerns.
Mixing open water and critical hardware would give any data center manager sleepless nights, no matter how efficient the cooling system claims to be.
A more reasoned proposal is the “Data Center Bunker”, which uses abandoned tunnels, bunkers or underground transit systems as secure data center locations.
Lenovo claims these underground locations “create a naturally efficient heat management system,” though anyone familiar with underground heat levels might disagree.
Still, the design offers benefits such as reduced floor space and improved physical protection, making it one of the few practical ideas in the collection.
Lenovo says future data centers must support the rapid growth of AI tools and automation while reducing carbon emissions.
Its Neptune liquid cooling system is designed to remove up to 98% of system heat directly from the source, reducing energy consumption compared to traditional air cooling.
The company insists such solutions are necessary as AI demand increases and data sovereignty rules tighten across regions.
These designs are only concepts for now, but Lenovo’s message is clear: unless data centers evolve quickly, the computers of the future will face physical and environmental bottlenecks.
“The data center of the future will be defined by how effectively it can scale to AI, deliver on sustainability goals and operate with maximum energy efficiency,” said Simone Larsson, Head of Enterprise AI, EMEA at Lenovo.
“As demand for computing accelerates, customers will increasingly look to infrastructure partners who can deliver performance without compromise…Future-ready data centers require a mindset where sustainability is not retrofitted…”
