CO2 doesn’t vary much in concentration by how close you are to an emission source unless you are literally sucking air out of a tailpipe. You might get a 10-20% increase in the centre of a city instead of the countryside, hardly enough to make up for being somewhere with so much energy coming in that they frequently have to curtail it (which could then be used for this instead).

This isnt CCS which cheaply turns CO2 into an inert form of carbon, its an expensive process for turning CO2 into a very useful form.

Sure, but you cant store that electricity as electricity. IMO this is most interesting as a energy storage technology, so the comparison isnt what that gasoline would do in an ICE car compared to an EV, its to what it would cost compared to battery storage (or compressed air or whatever other technology) to store a few weeks of output on the order of months. The big advantage I see here is that unlike those other technologies capacity is dirt cheap to build, its just a metal tank. So whenever a renewable plant would curtail its output it can instead redirect to creating gasoline to burn when the renewables arent producing much electricity.

I wonder is a scaled up version of this could work for grid-scale medium length storage. Smoothing out weeks of dunkleflaute is the main blocker to going to a primarily renewable grid. Gasoline is a lot easier to store than hydrogen and large scale gasoline generators should get close to the efficiency of natural gas peaker plants.

Just on a technical level that is an amazing ad compared to the usual political soundbites in front of a few images.

That doesn’t make any sense as a reason to turn off Gemini in your inbox though. Either you are ok with having your emails scanned and used in ML systems, in which case why bother turning off the feature; or you aren’t and turning off the feature doesn’t help you.

Google promises(new window) that Gmail’s 3 billion users will benefit from a “personal, proactive inbox assistant”. But given that these features are free, what’s the catch? Make no mistake, Google isn’t doing this out of generosity. The contents of your inbox are valuable to the company.

Email used to be a more private space where your communications could potentially be intercepted by bad actors, but largely your data was your own.

I dont think that is true wrt gmail is it? Google have been scanning your messages and using that for machine learning based ad targeting since it was released.
