New EV battery Tech Could Power Cars For Up To 1 million Kilometers

16 Jul 2025 | Synopsis

"New single-crystal battery design may allow EVs to last 1 million kilometers while reducing waste and environmental damage

"The heart of the problem lies in how these batteries charge and discharge...repeated charging and discharging causes the crystals to break apart. This weakens the structure and reduces the battery's ability to hold a charge...Unlike their multi-crystal counterparts, single-crystal materials are more resistant to damage..."

Cycling Can Be 4 Times More Efficient Than Walking. A Biomechanics Expert Explains Why

14 Jul 2025 | Synopsis

"You can walk for an hour - or jump on your bicycle and arrive in 15 minutes, barely breaking a sweat.

"It's estimated that there are more than a billion bikes in the world. Cycling represents one of the most energy-efficient forms of transport ever invented

"When we walk or run, we essentially fall forward in a controlled manner...On a bicycle, your legs move through a much smaller, circular motion...The energy savings are immediately noticeable."
