This afternoon's bike trip was a 37 km round trip in one hour and ten minutes to collect a 20 kg sack of "greensand" olivine for the garden.

I think it's a good example of the efficiency of velomobiles: how they make human power even more effective than when riding a normal bike. Even on the return journey with a headwind and loaded with the sack of sand, it was easy to keep the speed above 35 km/h.

Being able to stow a lot of things inside the aerodynamic form of the bike helps a lot with efficiency. You feel extra weight when accelerating, not so much once you get going.

And why the olivine ? I calculated a few weeks back that in the worst case this last winter our heating could have emitted 105 kg of CO2. This sack is enough to absorb about a fifth of that amount from the atmosphere.

Each time we plant things indoors or in our garden we add a bit of olivine.

Once humanity (especially those of us in the highly emitting richer countries) has reduced emissions by a lot, it's possible to make a bit of a dent by using a product like this. But there's no chance of compensating for ever larger emissions by trying to mine ever larger amounts of olivine.

"this #mineral can help turn #formaldehyde into sugars. The finding could help explain how the earliest organisms obtained sugars, which they use for energy and to build genetic molecules such as RNA and DNA."

Hooray! @MineralCup is here on Mastodon!

Starting September 1, amazing minerals will go head-to-head in an epic competition to determine which one will join #olivine #garnet #IceMineral #Magnetite #quetzalcoatlite and #fluorite as a #MineralCup champion!

Voting takes place on the Mineral Cup website, but campaigning takes place everywhere, including here. Follow the hashtag #MinCup23 for toots about what makes minerals marvelous.

#introduction post wahoo
I really like #megaten especially for the #mythology aspect; I love learning about demons and their origins. I'm currently playing #megamitensei2 , though at an incredibly slow pace since I kind of know what happens next at the Tokyo Tower. The music in this series is incredibly good even from its NES days!
Other things I'm into are #NUcarnival (#Olivine my beloved) and #fireemblem (particularly #fe4, with extra love for the substitutes )
That's it, I think.
