An material efficient and cost effective battery recycling industry would be key if we want a somehow durable way of keeping private vehicles. It's hard to believe we could provide 1 ton batteries to 5B+ people long-term without effici

What would be the impact of such fleets on electricity production management? As these charge overnight, I'm guessing USPS could easily program them to charge when the electricity is the cheapest (i.e. overproduced), or skip charges wh

The emergence of decent car sharing networks makes it even more cost-effective. Why would I own a 100kWh car, when I only need that range 2x per year, and I could rent that bigger car with my smartphone in 30 secs, for 1/20th of the an

Never heard about Galaxus, but looking at their e-shop, I felt like being propelled 10y in the future. Their UI is so much ahead any e-commerce website I ever seen.

I really like Scaleway: https://www.scaleway.com/en/ . Similar offer and simplicity as DigitalOcean, but way lower prices. I had to reach support a few months ago, and they were pretty responsive. They also show the pri

That's awesome. I've been using similar product previously, but these were either prohibitively expensive, or self-hosted. Keeping the link for later, thanks :)

Not $500/month yet, but I'm already having a few paying customers: https://noisycamp.com/ NoisyCamp is a platform for music studios to manage their reservations. It also helps musicians to find place to rehearse.

Will not the H2 tanks scale better than batteries for large scale storage? Battery capacity scales linearly (n) to material requirements , while a gas tank's capacity scales quadrically to material requirements (n^2, because of only us

250L x 7m is 17kN, or about 5W/h, or about 2 AA 2450mAh cells from IKEA. Pumped storage scales well though, as the stored volume scales squarely to the required container material (e.g. storing 25,000L will only take 10x the material w

Couldn't scheduling the EV charge when the demand is low while production is high help a lot balancing the grid, at basically no cost for the EV owner? Let's say I have a EV with a smart charger that will keep the vehicle at least

Well, you still need gas or coal to regulate your electricity production during surges.

Well, that also applies if Denmark wants uranium, oil or gas.

I guess it all goes down to the fraction of oil and natural gas in the average income of these countries. If your economy is more reliant on these (e.g. for heating, electricity or transport), all prices will go up significantly more compar

I had the same impression the last time I had to look at them. Basic payment processing feature are still well documented, but once you get into their Connect or subscription stuff, it gets a little messy.

While it might work and be actually safe, that does not mean it does not cost a lot to keep it safe for hundred of years (or more).
