It's a chicken & Egg problem. I run a startup in Pune, and we just don't get good developers here. We are open to remote, and most of the good candidates are in Bangalore.
Access to better schools is a factor in selecting a locality within the city but I don't think it has been a deciding factor in deciding the city itself.
Many cities including tier-2 cities have a variation of one of those "international" schools that parents seek and there's no significant difference in the quality of education between them.
Apart from the usual cycle of available talent + job opportunities, Bangalore has better weather and location wise it can attract talent from 4 states(these 4 states are major contributors to IT workforce compared to other states) while not being too far from place of origin.
better schools is not a factor at all. right out of college, or a little later most of the high quality engineers move to Bangalore because that's where the jobs already are. once people settle down a bit, they tend to be averse to move on average. it's network effect and sheer inertia. no one really wants it this way.
Hi! I'm a Geospatial professional involved in all stages of projects, and having experience in setting up of BaseMaps and GeoSpatial Application used in large scale applications. I also have a lot of experience in geospatial data and the intricacies that are specific to such data. I have built large scale data pipelines that ingest, and process geospatial data, and have bought several organisations into the modern world of cloud technologies.
To my knowledge, it's not common. The Auroville Solar Kitchen is pretty much precisely what I had in mind, and it's the first I've heard of such a thing. I'd really like to see more specifics on what they're doing, though it looks as if there are a mix of ovens and steam tables offered.
The use of a fixed-position spherical mirror (rather than parabolic) solves the problem of a moving aim point ... a spherical mirror always has the same region of focus, even if it "smears" that focus a bit. Since what's beeing gathered is heat rather than image information, that loss of precision makes for a more robust structure (particularly given high winds, as noted).
Other options would be flat absorptive panels (sufficient for pre-heating a working fluid to much-less-than-boiling temperatures) or a parabolic or hemispheric trough type reflector which focuses on a pipe or channel running the length of the mirrors.
I'd like to see some more technical information (a quick DDG search does turn up some promising results), and it seems there are some more extensive documents and specs.
