Some time, I wrote about the the collective, they might finally be ready to launch

As much as half the particulate emissions from a car, come from they tyres. While electric cars are far cleaner, this particulate emissions is particularly dangerous, to health so this move to do something about it is very good.

The idea is that a device is placed behind each wheel, and is statically charged, allowing it to collect most of the waste. The waste can then be recycled into tyres of into other things. Tyre wear accounts for about 28% of oceanic micro plastics, so it is an area we need to deal with – particularly because with their heavy battery electric vehicles wear down tyres much faster.

Most drivers on petrol engine cars, wouldn’t dream of driving without a catalytic converter – hopefully in the future the same will be said for tyre dust collectors. They should be on the market in the next few years.

Montpelier a city in France realized its error, and dropped an order for 51 hydrogen buses for electric instead

Montpelier had set aside $33 million for this project, over 2 years. This decision was made, after local officials realized that electric buses would be 6 times cheaper to run. This price included the building of a plant to make the hydrogen.

In terms of cost, it was estimated that the buses (for which the council was given help buying but not for running costs) would cost 3 million euros to run, yet only 500,000 for electric. The per mile price was 0.15 euro instead of 0.95.

Although they were going to be helped in purchasing, the hydrogen buses are also between 150000-200000 euros more to buy in the first place.

The myriad reasons that hydrogen is not a good idea have been obvious for some time. Green hydrogen (much of hydrogen is taken out of gas- obviously a nonstarter if your aim is reducing carbon emissions) requires a great deal of electricity to split water, and it would be far more efficient to just put that electricity in batteries and use them. Another issue is the compression of the gas. The only possible place where hydrogen might be useful is in aeroplanes.
