Companies like SolarCity basically install solar systems for no money up front, and then lease them back to you for a period. For many houses, even with these fees, the SolarCity systems will save the homeowner quite a bit of money. Licenses to sell power back to the grid are usually restricted, even in states they are allowed. If you have a battery system installed, you will no longer have to sell your excess solar energy back to the grid. You'll simply be able to store it in your battery for later use. Thus, homeowners with these systems may not have to apply for licenses for their solar systems, since they will not be doing net-metering. This will allow many users to install solar panels who couldn't before. It removes the ability for utilities and/or state governments to restrict the number of homes with solar panels. This is why these batteries will likely have a huge impact.

Yeah. Imagine if it happened on final approach.

I remember supporting an office with win95 and Access. I had tech support conversations that almost went like this:

The amazing thing about Elon Musk is that when he was a student he actually lived on $1/day for a while. He said that knowing he could live on so little was quite freeing, enabling him to take more risks.

I really don't think of him as your typical billionaire.

Yeah, the only difference is that Bezos founded Blue Origin in 2000, two years before Space X was founded, and only just now launched his first rocket. Bezos sounds like the Justin Hammer of the commercial space industry.

You purchase it so that you can store grid electrical energy while the rates are low overnight, and use it when rates are high during peak hours.

Yeah, it's called posting on an iPad :(

Then draw from the grid when you are cooking. Or buy two or three.

Uhhhhhh...gigafactory?

I don't think that is necessarily true. One option is to build hybrid electrical airplanes. And if battery power density and durability continues to improve, I think you might be surprised what is possible if you fill the wings of an airplane with electrochemical cells. Elon Musk has speculated that electric airplanes might be possible if we go beyond the incremental improvements of the current players.

Are you obtuse? Did you read what I wrote? I am criticizing monotheism as a whole. I probably despise extremism more than you do. I just see the historical context, and I see aspects of extremism in America that are similar to Islamic extremism. That is not being an apologist. It is being a realist.

I think the truly intractable problem is that such a system would centralize control of the educational system. Centralize it right down to every single word that is presented. The true power of the public education system is that it gives teachers a great deal of independence in what they say in the classroom. Imagine a situation when something terrible happens in our democracy. Someone seizes control. The system gets even more perverted than it already is. Then imagine an educational system where children only received "approved" resources. No independent human teacher. Just video and text. If the children don't get information from the media, then they will effectively be blind to reality.

I know this is hypothetical, but I think it demonstrates my point, that independent teachers are an essential buffer against tyranny emerging in our democracy.

I don't say that. I assert that mono-theistic religions have shown themselves capable of equally vile fanaticism, most especially when they are combined with the levers of power of the state.. See my post above.
