Paris's Smog Has Gotten So Bad, It's Making Public Transportation Free

Ah Paris—city of light, city of love, city of smog? Unusually warm spring weather has trapped diesel car emissions, blanketing much of France in noxious and dangerous air pollution. It’s gotten so bad that officials in Paris are taking the radical next step of making public transportation, bike shares, and electric car shares free to use all weekend.

What if all the ads in the world were replaced by beautiful art?

What if all the ads in the world were replaced by beautiful art?

Artist Etienne Lavie had a lightbulb bursting idea: what if all the advertisements we see on a daily basis in the street, on subways and billboards and so forth were replaced with beautiful works of art? Instead of seeing a C-list celeb shilling a sugar drink or a traditionally beautiful faceless model selling strips of underwear fabric, you’d see paintings and murals. The world would look so much more awesome.

Stinkhole Becomes Super-Pool with a Splash of Pink in Paris

Stinkhole Becomes Super-Pool with a Splash of Pink in Paris

Public pools in disrepair are sad to see and even grosser to go into. Atlas Sports Center was one such rundown, ’70s-era relic in Paris—a grubby stinkhole that had seen better days—but local firm Yoonseux Architectes transformed it into an ultra-modern spot to strip down and do a few laps (if you’re not doing intervals, because that definitely doesn’t look like 25 yards).

What a City Would Look Like Without Any People in It

Paris is the city of love. It’s a city of style. A city of taste. It’s a city where life ballets itself around you. Now imagine that dreamy Paris without any people. Without any life. Without any love. Scary! Claire and Maxime of Menilmonde filmed Paris and deleted people, cars and life from the footage and came with this deeply unsettling short.

This Week On The TC Europe Podcast: Paris Gets A Supersized Incubator, Tesco Does A Tablet & Valkee Flogs In-Ear Light

TechCrunch Europe Podcast

After a short hiatus, during which most of TechCrunch’s Europe-based writers packed their laptops and took off for San Francisco (for Disrupt 2013), the TechCrunch Europe Podcast is back to chew over a few choice nuggets of regional tech news.

On the slate this week, Paris getting its own supersized incubator: aka 1000startups — a massive startup factory that’s backed by Free CEO Xavier Niel. Our own resident Frenchman, Romain Dillet, is on hand to comment, albeit he’s not entirely convinced of the merits of this très grandes model…

Also taking up air-time this week, retail giant Tesco’s Amazon-style move into own-brand tablets with Hudl – as a way to expand the reach of other digital services it’s been trying to sell to shoppers, along with their Tesco Basics’ baked beans.

We also touch on Finnish startup Valkee’s winter-blues targeting headset, which takes the form of a pair of light-emitting headphones. Does it work? Who knows. Might we feel like shining light deep into our ear canals, during a long, dark Scandinavian winter? Frankly, who wouldn’t.

Join host John Biggs, plus TC’s Natasha LomasSteve O’Hear and Romain Dillet to discuss all these topics, along with an aside on the finer points of European irony. Background sound effects courtesy of the most fastidious money-counter in Montenegro.

We invite you to enjoy our (quasi-)weekly podcast every Thursday.
