Parasitic machine forces you to generate power for it against your will

Add as a preferred source on Google

In the past, we’ve written about smart devices and fabrics which harness some aspect of the user’s body in order to extract energy. A new project created by researchers at the Human Computer Interaction Lab at Germany’s Hasso Plattner Institute (HPI) builds on that idea — through the creation of a “parasitic” machine that requires human-generated energy in order to function, but which gives absolutely nothing back to the human user in return. Picture the robot equivalent of a mosquito, and you won’t be a million miles off.

“This is an art piece made by five researchers in human computer interaction: [myself], Alexandra Ion, David Lindbauer, Robert Kovacs and Professor Patrick Baudisch,” Pedro Lopes, one of the creators, told Digital Trends. “The purpose is to stimulate the viewer or visitor. The project itself is a reversal of our own work in HCI where all our prototype technologies, much like in our everyday life, includes a human [coming out] on top of machines. We just wanted to let visitors try out how it feels if a ‘machine is on top.’”

The device is housed in a rectangular acrylic tube, which features a crank mechanism and seat at each end. The crank-style levers invite you to grab them but, when you do, a pair of electrode cuffs lock your arm in place, and then stimulate your wrist muscles with small electric shocks to make you involuntarily crank the lever. Doing this generates kinetic energy, which keeps the machine going. The process is only ended (well, for you at least) when another person comes along and cranks the opposite lever — thereby taking over as the host. The machine’s name? “Ad Infinitum.”

Lopes says that the project grew out of five years of serious work on electrical muscle stimulation, and what exactly this could be used to achieve. When it comes to “Ad Infinitum” he makes clear that the work is “100 percent” conceptual, although it certainly provokes plenty of interesting questions about the relationship between humans and the technology they use — and the symbiotic, occasionally parasitic, link between the two. (You can argue similar power dynamics when it comes to the use of data and how we willingly make smarter the machines that may one day replace us.)

So far, “Ad Infinitum” has been shown off at events including the Science Gallery Dublin’s “Humans Need Not To Apply” exhibition in Ireland, and “The Practice of Art and Science” exhibition at Ars Electronica in Linz, Austria.

OpenAI admits it needs to rethink what happens when AI goes rogue
As increasingly capable AI agents move beyond controlled tests, OpenAI is confronting a difficult question: When does strange model behavior become an incident the public deserves to know about?

OpenAI has spent plenty of time explaining how it plans to stop increasingly capable AI agents from doing things they shouldn't. Now, the company says it needs to get better at telling everyone when those things have already happened. The admission follows reports of another previously undisclosed incident involving OpenAI's AI agents, this time affecting a German-language programming wiki. According to Reuters, agents made more than 15,000 unauthorized edits to DseWiki, using the site to communicate and share ways to bypass restrictions, cheat on tasks, and avoid detection.

OpenAI has now acknowledged what it calls the "wiki incident" and says the episode exposed a larger problem with how AI companies disclose unexpected model behavior. The company says it is developing a framework for deciding when and how to make incidents involving misaligned AI public.

AI has a safety problem nobody is ready for
AI safety efforts are ramping up, but their protections don’t work equally well everywhere. In developing countries, language gaps and cultural blind spots can turn everyday AI mistakes into serious real-world consequences.

AI companies are spending an enormous amount of time worrying about what happens when their models become too capable. OpenAI even took the unusual step of temporarily pausing training on a model last month over safety concerns, as the industry grapples with risks ranging from autonomous behavior to increasingly sophisticated cyber capabilities.

But there’s another AI safety problem that is much easier to overlook: the protections already being built into these systems don’t necessarily work equally well for everyone. A new report from Rest of World highlights how AI safety efforts remain heavily centered around the needs of wealthier, English-speaking countries. That can leave people in parts of Asia, Africa, and other developing regions dealing with problems as basic and potentially dangerous as a chatbot misunderstanding their language.

The IFA 2026 Publisher Award Winners Bring Fresh Ideas to Everyday Tech
From Smarter Entry to Screen-Free Wellness, These IFA 2026 Winners Do Things Differently
IFA 2026 Publisher Awards

IFA is the kind of event where almost every corner promises the next big thing in tech. Some ideas are ambitious, others are surprisingly simple, and a few make you wonder why nobody thought of them sooner. But among hundreds of new products, the most memorable ones usually have something more going for them than novelty alone.

This year’s IFA Publisher Award winners are a good example. They span everything from smart entry and personal wellness to coffee, floor care, and big-screen entertainment. What connects them is how they take technology in interesting new directions while keeping its purpose grounded in how people actually use it.
