No it's not. The utility for the users is the same. The lobbying power trying to make that choice is completely different.

I don’t agree. I got a feeling that in the political space we are given a binary choice between two dudes. The winner is then being courted by big-something to make a decision that benefits said dude. All the nuance and actual say about pre

I would argue that efficiency is more important only in offgrid applications where you absolutely need to get a specific amount of energy no matter what. If you are on grid but space constricted the price per watt or rather LCOE is more rel

Currently only gigabit network and I can easily saturate that. Thinking about chucking in 25gbit cards.

I have a 5-node ceph cluster built out of Fujitsu desktops that I got for 50 euro a piece. 4 nodes have 8gb ram and one has 16gb. CPU in each is i5-6500. Each has an NVMe that is split for OS and journal and a spinning HDD. The cluster idle

The cold places are usually extreme latitudes. I live around 60 latitude and here during the winter it might not be even that cold (tho it can be -20 or -30C). It’s that the amount of sunshine hours and the angle it shines at means that for

The thing that put me off veritasium was the electricity video which was immediately controversial. Looking at just the video he left the feeling that all electricity being taught is completely wrong while actually he was talking about some

Twitter nowadays has almost exclusively ads for ‘drops’ and ‘pumps’ and all other kinds of crypto scams.

This is like the peak of bikeshedding. Completely forgets the impact of climate change to the ecosystems.

4 billion tonnes of coal mined per year. 2021 produced 50 thousand tons of pure lithium. Coal gets used ONCE, lithium stores energy thousands of times before recycling to do it again. This kind of context is important before whatabouting.

There is that but there are also massive budget and schedule overruns that lead into lots of risk and interest payment expenses. Not to say that the whole industry does not benefit from learning curves. Solar and wind have had massive cost

You are talking about mostly unknown maybe externalities. I’m talking about the massive externality of climate change that is certain. Waiting for nuclear to maybe get its shit together is not a gamble that we can take. That said, I have no

Which other countries are building nuclear in a meaningful capacity? We need a reactor going online each week to make a dent. Not disagreeing that the regulations in the US are way too onerous for nuclear.

by jnsaff2 3y ago
Dreaming on both counts. We are in a situation where we simply can’t buy hopes, dreams, promises and marketing. Build or shut up. Nuclear is just not delivering. I wish it did tho.

by jnsaff2 3y ago
Sure. Reality is that solar is being built at a much faster pace than predicted for much cheaper than predicted. Nuclear. Crickets. Also you are overplaying the amount of panels covering land and sea.

This is simply not true. Here in Europe it is explicit that subsidies are not paid during negative prices. It can take more than 12h for some thermal plants to pick up steam after they have shut down. So it sometimes makes sense to produce

by jnsaff2 3y ago
Solar inverters can curtail super easy. It’s the thermal power plants that sometimes can’t, or rather it could be beneficial for them to pay for a few hours and not let off steam until there are profitable hours again. I’m pretty sure that

Seasonal energy storage (charge in summer and use in winter) with lithium is not feasible. If the medium would be cheap and could be pumped into arbitrarily large tanks that don’t need constant energy input to hold the charge then this coul

In my climate the problem is air being too dry inside during winter. Outside air is normal humidity 50-80% RH at -10C. Inside it will be 20% and way too dry. Ventilation, heat recovery and moisture recovery would be ideal. During summer we

The best that fits the desires, utility and constraints for you. If it’s best overall then best selling seems to be a fair way of removing bias as it is the best for most people.

by jnsaff2 3y ago
I would argue that sales is indicative of the best as it best matches the desires, utility and constraints for the most people. It removes individual bias from the equation as individually naming the best is impossible. Not disagreeing with
