  • 🔗 ongoing by Tim Bray · 4,000,000m Lessons

    The odometer on my e-bike clicked over to 4K and, rather than a general-purpose “e-bikes are great” rave, I thought I’d assemble a few concrete arguments for them, suitable for re-use with friends and loved ones in the (likely) case that you’re already convinced. With pictures.
    All of his points are spot on. For me it's mostly "it's practical", "infrastructure is human scale", and "it's fun". The "good for the city" and "good for the planet" arguments are just a bonus.
  • 🔗 Travel photos are underrated

    I snapped many photos while wandering Haifa last week, as I always do whenever I see something new or interesting while exploring a city. I was with my friend Tyler, who conspicuously does not take photos while exploring a new place. I asked him why,...
    This is one reason I made Trips. I wanted a way to re-visit my trips. Having your photos and a map make it so much more enjoyable to remember than a pro photo someone else took.
  • 🔗 Why did renewables become so cheap so fast?

    Fossil fuels dominate the global power supply because until very recently electricity from fossil fuels was the cheapest. This has changed dramatically. In most places power from new renewables is now cheaper than new fossil fuels.
    Fascinating read.
  • 🔗 The Revenge of the Hot Water Bottle

    Imagine a personal heating system that works indoors as well as outdoors, can be taken anywhere, requires little energy, and is independent of any infrastructure. It exists – and is hundreds of years old.
    Reminds me I should use my yutanpo more. But truth be told, Sophie always sleeps by me feet, so I already have a Sophie-tanpo.
  • 🔗 How we changed our roof and cut 1.5 tons of CO2e.

    Since Oct 01, 2021 we have saved 2,300 kwh, equivalent to 720 kg CO2e (assuming a 0.3g of CO2e per Kwh of heating gas). At current trend, we would save 5,200 kwh, equivalent to 1,600 kg CO2e until Apr 15, 2022. To put that number in perspective, a French emits about 9,000 kg of CO2e per year. Not bad for a roof.
    Fascinating how much easier we can cut with upgrades to the house that reduce carbon and improve comfort. Beautiful roof, too.
