A novel gadget is taking the concept of 'AI cranks' literally: a hand-cranked box that only provides answers once you have turned the handle enough to generate power for its processor. The device, which has caught the attention of tech enthusiasts, forces users to physically exert themselves while the AI computes a response. It is a playful but pointed commentary on the energy demands of modern artificial intelligence.
Unlike cloud-based AI services that draw power from vast data centres, this box runs entirely on human energy. The crank is connected to a small generator that charges a battery, which in turn powers a low-energy AI chip. Users must keep cranking until the answer appears on a small screen — turning a few seconds of waiting into a few minutes of effort. The creator describes it as 'a workout for the body and the mind'.
The device arrives at a time when the environmental cost of AI is under scrutiny. Data centres that train and run large language models consume enormous amounts of electricity, contributing to the UK's growing energy demand. The UK's Information Commissioner's Office (ICO) has urged organisations to consider the environmental impact of their AI deployments, while the EU AI Act includes provisions requiring transparency about energy use. This hand-cranked box, though a niche product, serves as a physical reminder of that hidden cost.
For UK businesses, the implications are twofold. On one hand, the gadget is unlikely to replace cloud-based AI for serious enterprise tasks — it is too slow and labour-intensive. On the other, it sparks a conversation about energy-efficient AI hardware. 'The real opportunity here is not the crank itself, but the push towards low-power processors that could reduce the carbon footprint of AI in offices and factories,' said Dr Eleanor Cross, a technology ethics researcher at the University of Bristol. 'If we can make AI that runs on a fraction of the energy, it changes the economics for small and medium-sized firms.'
Consumers may find the device a quirky novelty, but its underlying message resonates with a public increasingly concerned about energy bills and sustainability. 'What this means for you: while you are unlikely to use a crank-powered AI at home, the device points to a future where your smart speaker or thermostat could run on far less electricity — potentially lowering your bills and your carbon footprint,' said the expert. For the UK economy, which is aiming for net-zero emissions by 2050, innovations that reduce AI's energy appetite could be a quiet but significant step forward.
The gadget is not yet available commercially, but its creators have released the design as open source, inviting others to build their own. Expect to see more experiments in low-power AI hardware over the next year, particularly as the ICO and the EU AI Act push for greater energy transparency. Whether the crank becomes a gimmick or a genuine inspiration, it has already turned heads — and turned arms.
