I enjoy exploring by bike and on foot to taste new foods wherever I go. Data nerd frequently using Python and Power BI. Single car family against car dependency. Move people, not single occupant vehicles.

An update from the analysts at WoodMac: yes, as of 2025, solar PV remains the cheapest source of power in the world.

And -- bonus! -- it is still getting cheaper with every passing day.

Solar PV technology has maintained its leading position as the most cost-competitive power generation source in 2025, according to WoodMac.

who creates the lively art and music scenes if the rent is too high? who makes cultural life? who serves you food or washes your dishes? who creates the fancy little restaurants that draw you to urban living? affordable housing is at the heart of what makes city life worthwhile.

“Ontario’s plan to ban bike lanes is ripped from the business lobby’s wish list. Buried in a new omnibus bill, the latest salvo in Doug Ford’s war on bikes is more than a vendetta—it’s a gift to corporate lobbyists.”

The German company that makes the mechanical ladder used in the Louvre heist has used the image to advertise, with the text 'When you need to move fast'

Driving is dangerous, but often perceived as safe. Public transit is often safer, but perceived to be unsafe. Why? Perhaps it's because automakers spend far more on advertising, marketing & brand management.🧵

"...hoping to compete with grid-scale lithium batteries..."

The overall thermodynamic efficiency of this is about 70%.

Grid-scale batteries can do 90% and have no moving parts*.

The liquid air alternative to fossil fuels
When the grid needs extra energy, the liquid air is put to work. It is pumped out of storage and evaporated, becoming a gas again.

An overlooked technology for nearly 50 years, the first liquid air battery facility is finally set to power up in 2026.

Ask not how many cars you can power with solar power instead of biofuels, but how e-buses, trains, and e-bikes can move people affordably in a clean grid.

This video never names it, but it nails the “woozle effect”: when something seems true bc sources cite each other instead of an original. The term’s from Winnie the Pooh, where Pooh and Piglet follow their own tracks in circles looking for "woozles." Perfect metaphor for AI ouroboros poisoning info.

Does the news reflect what we die from?
Educated guess. The city has very few official bike parks. And that one is the only one that feels hidden.

Pretty neat feeling when you first spot that one. Short lovely wooded trail and then, woah what is that nestled in next to the railway tracks. Then you feel like a kid and drop in and enjoy.

People act like getting kids places without a car is Herculean. I biked three (one not mine) to the Kingfield Farmers Market, 95% on bikeways. No car seats, no stress, just laughs. The challenge isn’t moving kids, it’s redesigning cities to work for people instead of cars. #StreetsForPeople

Something I haven't seen any mention of along with the law enforcing SPEED CAMERAS that Doug Ford wants to outlaw is the law enforcement RED LIGHT CAMERAS. They serve the same purpose of punishment for violations of the Ontario Highway Traffic Act. Will he outlaw them too, if not, why? #OnPoli

All the time I hear about how we can’t have bike infrastructure in our cities because cyclists "don't follow the rules of the road".

Yet, almost no driver follows the speed limit, one of the most important rules. Worse, many are actively offended by enforcing those basic rules.
Reposted by Kris Hammel
If people think speed limits are bad, they should own that and argue to raise or eliminate them, not just neuter them by eliminating enforcement.

I hate that we post rules and then don’t treat them as real. Either enforce or change the rules.

Same with stop signs. Enforce them or make them yields.
I wish we had a culture of driving that respected rules like speed limits. Instead, we have a culture where enforcing basic useful rules about how fast you can operate a multi-ton machine is considered “unfair” or a “cash grab”.

Doug Ford to outlaw municipal speed cameras in Ontario.

Any person, any time of day.

Whether schools are in session or not:

walking
cycling
sitting in a cafe
On a skateboard
Pushing a stroller
waiting at a transit stop
getting on/off a school bus
In a pedestrian cross over
Taking their dog for a walk
#DYK that if a person cycling is struck by a driver travelling 50 km/h, their chance of survival is only 10%? Whether you’re a new or experienced driver, always drive carefully around vulnerable road users. 🚴
