Tesla Motors plans to announce that it has solved the biggest problem with alternative energy. Energy Storage.

Elon Musk hinted about an announcement for a new product line for renewable energy storage last week, suddenly, that dream became a step closer to becoming reality.

“It signals that the storage market is at a point where end customers have been looking for big companies to have their product in the market,” said Ravi Manghani, an analyst for GTM Research. “It’s a small-but-growing [and] very competitive space and Tesla’s putting its stake on the market.”

Tesla will have a big impact on this conversation and the progression of the energy storage industry, but of course, the announcement can’t change the course of history on its own — so don’t get too excited. We still need government regulations and changes in utility models,

Ah. Government regulation. That is kind of an implicit admission that the devices are not profitable.

Lets run the numbers. the average home in the US uses 909 KWh a month. Divide by 24 hours in a day and 30 days in a month and you get about 1,250 watts on an average basis.

We don’t have any real numbers yet but the article estimates a $13,000 cost (ouch) for a 6 KWh battery. That battery will run your home for about 5 hours. Suppose you are paying 25 cents a KWh for electricity (electric power plus grid services). It will take you 52,000 hours of battery use to break even. Assuming the cost of charging the battery is zero. Which it is not. That is about 6 years if the battery charging time is zero. Which it is not. And that assumes the battery will operate that long. No battery life is given. Typically lithium batteries last 3 years. But let us say this one lasts 6 with out declining in capacity until it needs to be replaced. That means you can’t break even for the life of the battery unless your electricity cost is zero and your charging time is zero. And that is the most optimistic scenario possible. And assumes the time cost of money is zero.

And BTW since your house is now a source of electricity your service will need to be upgraded with an automatic cut off switch for times when grid power goes to zero. Both to save your charge for your use and to keep grid electricians from getting electrocuted from unexpected power while making grid repairs.

The answer? It is always the answer. Men with guns can make the uneconomic seem reasonable.

Every tax, every regulation comes with it an army of bureaucrats and behind that an army (with guns) of enforcers.

He has erected a multitude of New Offices, and sent hither swarms of Officers to harass our people and eat out their substance.

I’m sick and tired of phony crony capitalists.
