I didn’t know about the newsletter, thanks!

I’ve worked in IT. You are most likely correct, and anyone with any sense would do it that way, but I would absolutely believe that someone could be incompetent enough to use the computer’s time stamp. I also wouldn’t be surprised if users had access to change the clock.

I want one now.

Technically there is a limit. You can’t go past 180 degrees without changing the rendering code.

Thanks for this post. It has taken me down the rabbit hole of new software.

I now have f-droid and simpletask on my phone, sleek on my computer, and syncthing on both.

I have needed a really simple to-do list synchronised between my phone and computer for years, and just didn’t know this was an option. I’m very happy now.

Would it prevent you from seeing a parliament of superb owls?

I have a 2011 Nissan Leaf AZE0 24kWh with about 40% battery degradation. It can drive about 80km (50mi), which is perfectly adequate for a second car. It is rarely driven more than 20km in a day.

My other car is a 2018 Nissan Leaf ZE1 E+ G 62kWh with about 4% battery degradation.

The fastest battery degradation happens when the battery is new, and the degradation slows down gradually over time. I expect the 2011 Leaf to still have at least 50km range in 2041, and the 2018 Leaf to still have at least 200km (130mi) range in 2038. Both of these will still suit my needs.

Most large combustion SUVs are heavier than most electric cars.

Sodium ion batteries are being produced with no rare metals in them, and will be in production cars within a year. Hydrogen is difficult to store due to is low volumetric density, it’s molecular size, and corrosive nature.

Hydrogen (fuel cell) cars all have a battery because a hydrogen fuel cell is slow to change it’s energy output, so can’t change its output fast enough to directly power the car.

Battery electric cars are about 90% efficient from charging from the grid to moving. Hydrogen cars are about 30% efficient from grid to moving when made from renewable energy. These efficiency numbers include the weight and rolling resistance of the car. The theoretical maximum efficiency of hydrogen storage allowed by the limits of physics is about 50%.

The volumetric density of hydrogen is so low that you would need 20 tanker trucks to transport the same amount of energy that 1 tanker truck of gasoline can carry. This is at maximum pressure or liquified.

Hydrogen only makes sense when the weight of the energy storage medium is critical. As demonstrated by American cars, it isn’t.

Hydrogen is only 30% efficient compared to 90-95% for batteries. Most hydrogen is currently made from fossil fuels, and contains less energy than the fossil fuels used to make it.

I’ve had an electric car since 2011. The battery looks like it will last another 10 years.

Early Nissan Leaf batteries degraded relatively quickly (8-10 years) due to poor battery chemistry and no thermal management. Both of these issues have been fixed in all new electric cars (except the new Nissan Leaf which still doesn’t have battery cooling).

Even the old degraded batteries are valuable as static energy storage, and several people are using them as house batteries.

Most of the cost of a battery replacement is the manufacturer markup. There is at least one company making replacement Nissan Leaf batteries for significantly less than Nissan, and they include the latest chemistry and liquid cooling (unlike Nissan who just give you a second hand battery).

Most electric cars today have a 10 year warranty on the battery. Manufacturers wouldn’t be offering that if there was a reasonable chance you would need to replace the battery in that time.

I’d recommend an electric car for avoiding oil changes, but I think we still have a few more years until cheap second hand electric cars become available.

Personally I prefer to just avoid clicking on dodgy links. In the last 5 years I haven’t found any viruses. YMMV

Most electric cars have battery cooling, but the Nissan Leaf doesn’t. It works fine until you try rapid charging more than 2 times in one day.

I suspect that some high performance cars would also have motor and inverter cooling. This would likely not be needed for regular road cars as the motor and inverter don’t produce much heat.
