This is a H2 fuel cell. They put two of these hydrogen fuel cells inside a regular Volvo truck.

1000 km range, up to 65 ton vehicle, fill the tank with green H2 in 15 minutes.

The inch is one of the leading units in the world and a natural choice for the sophisticated European scientist.

A state in Germany found that battery trains are better than hydrogen trains.

They are buying 102 battery trains to replace their diesel trains.

Maybe batteries wins over hydrogen for all land transport?

What are American school buses doing most of the day? 🤔 Are they parked? Is the driver switching to a regular bus? :blobcatwhat:

Anyway, here's an electrical school bus 🙂

Started sketching up a front page for the new community website :flan_hacker:

Can we brainstorm some words and short sentences for it? :ablobcatcoffee:

Got "Green", "Social", "Servers" so far. Do you have any better ideas?

Nuclear lost against coal in the EU, and now it's losing against renewables.

Nuclear energy is dying in the EU.

No new plants, only decommissions, and that in times of quickly growing electricity demand.

Meanwhile solar energy grows fast. It more than covers for the decommissioned nuclear and coal energy.

Europe - the world's fourth-biggest greenhouse gas emitter after China, the United States and India.

EU has ... the most ambitious climate targets - to cut greenhouse gas emissions by 55% by 2030.

Maybe even able to do 57 %. I imagine things are going somewhat faster now when the war cut gas supplies.

The change to electric cars is going to be almost as fast as Sweden changing from left- to right lane driving back in 1967

In only 12 years 100 % of all new cars in EU will be electric

🇫🇮 Wind power is racing ahead of nuclear now 👇

Finland's current wind power capacity is 5700 MW

Myrsky Energia has wind power projects underway with 5000 MW

OX2 has more than 9000 MW of wind power projects pending

Say that we want to store nuclear waste for 100.000 years.

How would we communicate to a human to stay away from it? A sign in French and English probably won't be understandable after 100 kiloyear.

I've published a new blog post on the topic of Threads.net and Mastodon.green. Do you have any thoughts on it?

This solar panel is about 200 cm times 40 cm and 2 mm thick. Made by Heliatek. It's pretty neat. With glue on the back it's just a matter of pressing it onto the wall and plug it in.

Probably falls off 😅, unless it's superglue? 🤔

Would it be technically possible to gradually upgrade the grid in the USA from 110 V (60 Hz) to 230 V (50 Hz)?

Perhaps by mandating that all new installations should be able to handle a future switch? Or perhaps by going street by street, house by house, and switching it over?

Wikipedia says that the UK will close its last coal power plant next year.

They replaced most of the coal with gas during the last fifty years.

There's day and night.

We know the difference, in the day the sun is up and in the night the moon is up. 🌞 🌛

Then there's the word for a 24 hour period, not necessarily starting at 00:00.

In English that word is "nychthemeron". A clunky word. Other languages have better words.

We should create a new English word for it, for example "mero", "para" or "doba"
