"time-smoothed electric grids". Exactly, this is actually where Lithium batteries make the most sense, especially with solar. It isn't to provide 100% backup output at a grid/utility scale but to make output more consist

No, as the cost of actions/methods/waste/materials of production aren’t always captured, the driving down of costs through competition actually encourages the discovery of externalities (ways to externalise the cost/impa

Gold has a actual use as a commodity, eg in electronics and other equipment, and derives a minimum value as such. So whilst how gold is used in trading circles might have similarities to BTC, this difference IMO makes them nothing alike.

You make it sound as if it is reasonable for a transaction is to cost 2kWh, that is a huge amount of electricity/energy. If anything that used that much energy became the dominant means of payment, the average person would use more ene

I agree with the small vs large. Would be interested in at what head count you’ve seen this transition happen? Especially the need for project/product managers.

I’ve felt the same and I grew up with those older games (I’m 35). There are still some greats coming out but you have to seek them out and filter out a lot of games these days to find them. If you are interested in game design and more on w

For me, ECS having less to learn was its main appeal. You get integration with AWS load balancers giving zero down time deployment and its API to automate is very straight forward. I set it up 2 years ago and have barely touched it. I evalu

The killer app of EVs with access to home chargers (even slow ones) is that going somewhere else to fill up the car will be a rare occurrence. UK stats show EVs only charge outside home or work ~7% of the time. For a minority of people, reg

Watts per square meter of solar radiation is ~1kW before taking into account solar panel efficiency (usually ~20% these days) so it just doesn’t generate that much power on the roof of a car to be useful.

It’s not an encoded price but some smart grid connected devices do use the frequency as an indicator of the grid has lots of demand (slightly lower frequency, generally higher price) or lots of supply (higher frequency, generally lower pric

Right, maybe that is a reason it has been avoided by VCs? Not many 'purely' software options? Most of these problems probably do require a hardware component for the solution. Battery arbitrage (quite a bit of software involved he

Ahh thanks for pointing those out I missed those skimming for `Wh`. "Storage needs to provide 55GW" seems to come from peak consumption rate considering gross yearly generation was at 556TWh in 2014. https://en.wikipedi
