Thanks. I don't know much about the project, so I didn't pick the best performance ratio.
It might end up being over 90%. It also could end up much worse, with either shadowing, module mismatch, inverter mismatch or soiling.
I've seen big projects where almost a dozen inverters (out of many hundred) were either out of order or even not connected at all without anyone noticing for over a year.

Your calculation is a just bit too simple and optimistic.

Madurai (about 50km away from the power plant) has an average global horizontal irradiance of 224W/m**2.
At 9 degree latitude North, the optimum tilt angle is pretty close to horizontal : 10 degree tilt only brings 2% more irradiance over the year

Total insolation is year * average irradiance ~ 1960kWh
The performance ratio of such a power plant could be around 85%, with cable losses, inverter losses and automated cleaning.
The nominal power of the installation is 648MWp, tested under an irradiance of 1000W/m**2.
So your expected yield is :
1960kWh/(m**2*year)*85%*648MW/(1000W/m**2) ~ 1.1 TWh/year

compared to your result of 1.9 TWh/year.

The plant should pay for itself in less than 8 years, and your calculation wasn't too far off.

You're right that its unsustainable, but every business that automates will only be thinking about their own bottom line and not about society as a whole. If they don't automate, they will be uncompetitive against others that do.
Consumers would need to vote with their feet and opt for the more expensive non automated suppliers in order to discourage the trend, but people wont because again they only think about their own bottom line.

Trying to prevent reverse engineering is pointless, all you can do is make things more difficult and in doing so, making your code more complicated and harder to debug or potentially unreliable.
The fact is if you access something from a compromised device then you run the risk of whatever you're accessing being compromised too.

It's pretty easy to understand why Obama didn't close Guantanamo :
There are many innocent people there. If they weren't terrorists before entering there, they sure would be now after 15 years of inhuman treatments.
No country wants them, so they'll rot there for eternity without ever facing a trial.

Obama learned the lesson, and just gave the chairforce orders to use more drones.

I would quite happily watch the ad supported version (have been watching broadcast tv for years), if it provided a decent service...
Having to use specific devices to access the services, having a bunch of different services rather than a single standard usable from any compatible device (like broadcast tv), having drm etc is a big turn off.
