In regions where electricity is costly or unreliable, energy efficiency becomes a critical factor. EVE addresses this challenge with a design that minimises power consumption.

The Raspberry Pi control unit uses significantly less electricity compared to the industrial-grade computers found in high-end bioreactors. To further conserve energy, bacterial cultures can be maintained at room temperature, eliminating the need for energy-intensive heating systems [1].

For sterilisation, users can opt for pressure cookers instead of autoclaves, which are known for their high energy demands. This method not only reduces energy use but also makes the process more practical in areas with inconsistent power supply [1].

Scalability

EVE’s modular design makes it easy to scale operations. Facilities can start small with just a few culture units and expand gradually, avoiding the steep upfront costs associated with larger commercial systems.

Future plans for EVE include exploring alternative hardware construction methods that eliminate the need for 3D printing, further reducing costs and making the system accessible to regions without advanced manufacturing capabilities [1].

Moreover, EVE’s open-source nature fosters a global network of collaboration. Improvements or upgrades made by one user can be shared with others, creating a dynamic ecosystem of shared innovation.

Ease of Maintenance

EVE is built with locally available components, ensuring quick and straightforward maintenance. Parts can be sourced from local suppliers or standard electronics retailers, avoiding the delays and high costs often tied to proprietary equipment.

The Python-based software has a large support community, making troubleshooting more accessible. Many technical issues can be resolved through online forums, eliminating the need for costly specialist technicians.

This approach ensures that routine maintenance is quick and doesn’t disrupt production for long periods. With standard electronic parts that are easy to replace, EVE keeps operations running smoothly - an essential feature for commercial viability.
