He said, "The sun does not shine at night." Since when? The sun doesn't turn off -- it shines continuously. When it is not shining in your geographic area, it's still shining somewhere else.

He mentions how many KWH it provides but for how many hours can it provide that at maximum capacity? What kind of maintenance is required? Batteries usually have a limited lifetime. For example, how often do you need to replace the batteries in your car?

Since Tesla only provides a 10 year guarantee, it seems like they know there will be prolems after that time and it will require expensive replacement. According to the specs, i's just a simple lihium ion battery and I've had many of those fail in digital cameras and cell phones.

At least this guy is trying to make a difference to the way energy is made, stored and used. He is at the front of the clean energy revolution and, although he might be swimming against the corporate tide that only seeks to make money for itself, there are a growing number of people who see the sense and benefits of this work. I don't bandy words like 'genius' or 'visionary' around much, but Elon Musk has some innovative and sensible ideas which we would be wise to consider very carefully. If we don't, my grandchildren and great grandchildren may reap the catastrophic rewards of our mistakes.

Stop nitpicking, stop tearing holes in his presentation and get on board.

Is that what he's doing? Trying to make a difference in the way energy is made and stored and used? What is innovative with this product? It doesn't change the way energy is made, stored, or used. Lithium ion is old technology.

I think Eon Musk is doing this for profit and not to make a difference. He's a multi-billionairre and could give me one for free if he wanted but he is planning on charging me for it instead.

If you don't have the brain to see what this could mean, there's no point in anyone trying to explain it to you. All you are doing is trying to tear the whole idea down with silly criticisms and moaning that the man who has made a lot of money with new ideas won't give you something for nothing. Boo hoo, sucks to be you.

In my area, we use the net metering system. This means any excessive energy that I produce will cause my meter go to backwards. Then, at night time, when I use electricity off the grid, my meter runs forward again. If I produce enough in the daytime to make up for what I use at night, my net costs will be zero (less a service charge that the electric company imposes to all their customers).

Bottom line: Why would I want to spend several thousands of dollars for this device when it will not save me money?
