Really cool, I see now that most all the the Racket extensions to Chez have been up-streamed which is positive for the health of both projects.

Awesome work, have you looked into using Racket's fork of Chez? It supports some additional extensions and architectures from base Chez that would seem to beneficial as a compiler target, at least that was the case a couple years ago.

I agree I don't think it will always be the case but in the 1-5 year term the economics dictate that is what you get, full battery backup to run something like a data center is expensive even if technically feasible. It is not 1:1 bac

During the Biden administration almost 40 trillion ft^3 of natural gas was produced annually breaking all records. I do agree the policies of energy were more all the above during Biden and renewable build outs were incentivized additional

As much as I wish it were different I think this would be the outcome under any administration. Natural gas in the USA is just stupidly cheap inflation adjusted, is energy dense, power plants require few land resources, pipeline infrastruc

Some of the largest proposed data centers in the US are in Pennsylvania, West Virginia, and Ohio. The electricity infrastructure is important so is cheap natural gas from the Marcellus shale, natural gas pipeline infrastructure and relaxed

Any advice will really depend on where you live and the dominant source of local error. These are all good options for the US and if the one main source of error is near surface winds around complex terrain then you can also look into Wind

When you say runs that is an ensemble model forecast which is different than a deterministic model forecast. Any type of weather model sensitive to initial input state errors will have outlier model runs.

Traditional physics based weather models also rely heavily on physical parameterization for sub grid scale processes (think clouds, microphysics of rain sleet snow, etc) so even the deterministic physics models are learned approximations fr

ECMWF has an experimental AIFS direct observational prediction model (AIFS-DOP) that has become competitive with their physics based IFS model on certain metrics just in the past year. https://arxiv.org/html/2606.19093v

Heat domes are already killing off cattle and reducing crop yields, even in western countries? There was significant cattle die off in the US during 2022/2023. Europe just experienced 10,000 excess deaths due to heat impacts and a re

Its a bit more complicated than that, you have a period during the spring called the spring persistence barrier that makes skillful prediction of a developing el nino difficult. What is impressive is that multi month model predictions befo

Its regionally complicated because increased tree cover can lower albedo (reflectivity of radiation) which offsets the co2 removal benefits. Forrests can tip from co2 sinks to co2 sources which is happening in different regions of the worl

Being next to a nuclear power plant but attached to a regional grid is not that relevant in terms of total additive emissions from a data center build out. You have to look at the change in emissions of the grid as a whole. Companies are in

The nuclear generating station is part of a larger system. Say you build enough data centers in your local area to use up all the station power so that 80% is no longer exported, what is getting built somewhere else to make up for that mis

It is much more than the Colossus sites, I would look at the capacity additions in the regional grids you are apart of and what is being funded to meet these increases in demand from data centers. The majority of it is natural gas generati

The amount of nuclear generation is roughly fixed (minus the refurbishment of three mile) in that region. If you add additional large load to the grid and outbid other demand for that power you are just shifting the load you replaced to ot

But in PJM they are almost entirely being powered by natural gas and coal? Even if you contract out power from a nuclear plant some other plant on the grid is now enjoying a higher capacity factor, at the margin natural gas. The data cente

Emigration of Germans to the USA is only 10,00-15,000 people per year since 2000 and is trending down especially since 2016 to lowest levels ever. Emigration of US citizens to Germany started from almost nothing around the same time and is

In traditional fault hosted (not magmatic) geothermal the convection of the water up the fault brings the thermal energy closer to the surface where drilling depths are economical. This convection heats the surrounding rock and over hundre
