Smog-Free Bicycle’s pedal power could scrub pollutants from Beijing’s air

By Luke Dormehl Published May 18, 2017

Riding a bike instead of driving a car may be the more environmentally friendly choice of transport, but could bicycles actually help fight pollution more directly? The Netherlands’ Studio Roosegaarde claims the answer is a resounding “yes” — and it’s got its eyes set on Beijing’s notoriously high levels of smog to prove its point.

Right now, the Smog-Free Bicycle is still just a concept, but it’s a pretty darn intriguing one that’s already captured our interest. “It is still in development, but as with our Smog Free Tower, it sucks up the dirty air and releases clean air in its vicinity,” creator Daan Roosegaarde told Digital Trends.

The Smog Free Tower that Roosegaarde refers to is a 23-foot wind-powered structure that essentially functions as a giant air purifier. In a study by Eindhoven University of Technology, the technology used for the Smog Free Tower was found to remove up to 70 percent of the ingested PM10 and up to 50 percent of the ingested PM2.5 — two of the pollutants which contribute to smog. In an open field in calm weather, the Smog Free Tower is able to cause smog reductions of more than 20 meters around it.

Roosegaarde’s idea is to now take that technology on the move with a bicycle that releases positively-charged ions into the air, which then capture pollutants and suck them back inside. “It reflects our drive to activate new solutions together with citizens, makers, NGOs and governments towards smog-free cities,” he continued. “The Smog Free Bicycle, along with Smog Free Tower and Smog Free Jewellery, are part of the larger Smog Free Project. More concepts will be added along the journey.”

At present, Roosegaarde said the team is working on a prototype, which it will be developing with a partner in China and the Netherlands. One possibility is that the bike will be used in local bikesharing programs in China, such as Mobike. There’s no word on when it might be available as a commercial product that international customers can get their hands on, but hopefully we won’t be waiting too much longer.

Google has been finding more ways to make Gemini a part of your daily routine, from putting together playlists to ordering groceries through your favorite apps. Now it's expanding those capabilities to more services, with Google Search joining in, too.

The company has announced a new Connected Apps Platform that makes it easier for developers to bring their services to both Gemini and Search. Alongside this, Google is adding new partners to its growing lineup, bringing more of the apps people already use into its AI ecosystem.

AI bots are now trying to sabotage public health policies, like banning disposable vapes

Thousands of AI bots voted in a public health poll to block sales restriction on disposable vapes. It's like Big Tobacco is back from the dead.

In the broad context of AI and its perceived harms, health and medical risks often pop up in the conversation. The warnings even come from frontier AI labs, such as ChatGPT-maker OpenAI and Anthropic, both of which have warned about misusing AI to cook up bioweapons. Security experts have already spotted a few such incidents in the wild, especially with the usage of AI models without any solid guardrails.

Well, it appears that the risks run deeper. As per an analysis appearing in the British Medical Journal (BMJ), AI bots are now being deployed to influence public policies governing health risks to citizens. In this instance, an attempt was made using AI bots to thwart regulations that aim to restrict the sale of disposable vapes, all while disguising the manipulation efforts as a response from real humans.

A tiny smartphone gadget can detect some of the nastiest chemicals in your water

Scientists built a tiny smartphone gadget that can spot toxic 'forever chemicals'

What if checking your drinking water for dangerous chemicals were as simple as plugging a tiny gadget into your smartphone? Researchers in Japan have developed a compact sensor that could make that possible, potentially bringing sophisticated water contamination testing out of expensive laboratories and into people's hands.

Scientists at the Okinawa Institute of Science and Technology (OIST) have created a portable device capable of detecting extremely low concentrations of PFAS, commonly known as "forever chemicals." The findings were published in the journal Biosensors and Bioelectronics, which demonstrate how an inexpensive sensor and a smartphone could make identifying potentially harmful chemicals in water a lot easier.
