Toyota recalls 2,840 Mirai cars due to power issue


Toyota Mirai

Toyota has recalled all its revolutionary fuel-cell powered Mirai cars due to problems with the power.

It means that all 2,840 of the zero-emission Mirai cars sold across Japan, the US, Europe, and United Arab Emirates are subject to the recall, with the firm promising to fix the issue free of charge in just 30 minutes.

According to Reuters, it occurs "under unique driving conditions, such as if the accelerator pedal is depressed to the wide open throttle position after driving on a long descent while using cruise control, there was a possibility the output voltage generated by the fuel cell boost converter could exceed the maximum voltage."

Anyone affected by the issue can head to a Toyota dealer and have the software updated, a process that takes approximately half an hour.

Customers have been able to snap up one of the hydrogen slurping Mirai vehicles since December 2014. Shortly after that, the company moved to release thousands of patents related to hydrogen fuel cell technology to try to trigger growth in the sector.

Toyota has been one of the foremost developers of technology that reduces the impact cars have on the environment. The company announced earlier this month it has sold more than 10 million hybrid cars worldwide since it first released the Coaster Hybrid EV coach and Prius back in 1997.

The UK government is also throwing its weight behind cleaner technology in cars and launched a scheme last year that gives public and private sector fleets up to 75% off zero-emission fuel cell electric vehicles.

That £2 million fund is the first part of an ambitious plan to make almost all vehicles in the UK zero-emission by 2050.

This is madness. These cars are only zero emissions if you look at them in isolation, much like wind turbines. When examined as part of a system they are monstrously polluting. The way we make hydrogen is by blasting methane with high pressure steam a couple of times - we can do it by electrolysis but this is even more energy intensive. This produces hydrogen and carbon dioxide (a small amount so not a massive issue). So how do we get the energy to make the steam? Oh right, burning hydrocarbons (mostly gas). So you burn hydrocarbons at a poor efficiency to extract hydrogen which has a low energy density (and therefore you can't store as much so you need more tankers to get the same energy content to the stations) which you then burn at a meh efficiency to generate energy to move... when you could just burn the damned hydrocarbons to start with.
Unless we start extracting hydrogen through electrolysis powered by nuclear, all we're doing is burning even more hydrocarbons for the same amount of end result energy due to the massive losses in each energy extraction / conversion process.
These are NOT zero emissions vehicles, they're a menace to the environment.
