- Comment on World first UK prototype could pave the way for constant energy all the time - from space | Science & Tech News 2 months ago:
To complete that good answer, basically satellites in GEO will experience eclipses 2x21 days per year (around March and September). The eclipse duration during these period will vary from 0 to 70minutes and then down to 0 again, with one eclipse per day, around midnight.
So your solar plant in space will work 100% of the time 320+ days a year, and will have a small down time that can be up to an hour in the middle of the night otherwise. Not perfect but actually very manageable with a little bit of storage on the ground.
Overall, the main concern with these systems is the total cost, including launch cost. It is hard to tell if it will be competitive with solar + battery on the ground.
- Comment on Do bike tires increase pressure in summerm 3 months ago:
To do the math, an assuming constant volume, a 30C increase corresponds to around 10% increase in pressure. That’s well within the margins of the tyre even if you go to the max rated.
If you then consider deformation and most importantly leakage over several weeks, this is a non-issue.

This.
I don’t mind if they use the average household number in the title or header, that’s understandable. But such an article should have the actual values somewhere.

That will be a nice explanation when they arrive in prison.

- Comment on ‘The quotes were £5,000 or more’: electric vehicle owners face soaring insurance costs 8 months ago:
I would be tempted to say that with EV cars still being biased for the higher quality cars, and with Tesla still having a majority of the market, this should push the average cost of repair. Not sure when Tesla will fix their repair chain issues.
- Comment on Why don't we pump seawater into deserts to revive them? 9 months ago:
Even as a slave, the cost of a human work is magnitudes above the cost of using a pump with petrol. A slave may be able to output ~1kWh per day, that’s mostly a few 10s of cents anywhere. Can you feed anyone on that?
