Vaire Raises $4.5M for Reversible Computing to Reduce Energy Needs

DateJul 2, 2024

Vaire Computing, an innovative startup specializing in reversible computing technology, has successfully secured $4 million in funding. This investment round was spearheaded by Internet entrepreneur Jude Gomila and venture capital firm 7percent Ventures, which focuses on emerging technologies. Additional support came from Seedcamp, Clim8, and several angel investors.

The funding round was announced yesterday by TechCrunch. Traditional computing methods generate significant heat during data processing, necessitating extensive cooling systems in data centers that further consume energy. Vaire’s novel approach with reversible computing aims to address this inefficiency.

The London-based startup asserts that if their technology is commercialized successfully, it could revolutionize processor efficiency, leading to cooler operation, reduced energy consumption, and lower operational costs. This breakthrough could particularly benefit businesses handling complex tasks like big language models, which currently require substantial computational resources.

Cutting Down on Power Use and Heat Production

To understand the impact of reversible computing, consider the limitations of conventional processors. When adding two and two on a calculator, the result is four, but the sequence of inputs leading to that result is lost. Similarly, modern processors perform billions of transistor operations without retaining intermediate steps, akin to how a calculator displays a result without showing the button presses.

Reversible computing, however, operates on a different paradigm. This technology theoretically allows the retrieval of every computation performed, such as updating a database or deleting a file, by embedding an undo function within each transistor. This capability enables the processor to reverse its operations and recall previous calculations, potentially reducing power consumption and heat generation.

The concept of reversible computing isn’t new. It was first proposed in a 1961 study by an IBM researcher. Despite decades of research, creating a commercially viable reversible computer chip that matches the speed and cost-efficiency of traditional processors has proven challenging.

Vaire Computing believes it can overcome these hurdles. According to TechCrunch, the startup intends to use its newly raised funds to develop a proof-of-concept for reversible computing. Upon demonstrating the feasibility of their technology, Vaire plans to seek additional funding to create a fully functional chip.
