Yeah they had an agreement with Panasonic to make that factory in US to produce billions of cells. Makes sense to expand to such areas when 8000pcs of 18650 are used on some Tesla models, at that point cells become actually you main business even if you sell cars and make space shuttles on the side.
Well, the green idea for renewable energy plus batteries storing it is quite tempting, but considering the fact the producing those batteries isnt that nature frendly, plus they cant be recycled atm…and the fact that even offshore wind generators have 30% uptime and the average PV world uptime is 15%……not that good idea
You cant reply upon that
Yet, nuclear power plants + mix of PV stations and wind turbine ones i think is the future
O.T
My little son adores wind generators, but the noise arround them when they work is unbareable
If you can buy electricity cheap in the night such a battery will make sense even without solar panels….
Until now I thought that batteries and rechargeable battery will be recycled…have to google that later…
I must be tone deaf. When I’m up in the thumb of Michigan where there are lots of them and I can’t hear them making noise when I’m only about 800 yards from one. Do you have to be right next to them to hear it?
I just don’t see how this is going to be better for the environment than a good power grid.
And why on earth isn’t Tesla offering to use the battery inside your Model S to power your home? 80kWh standing in the garage, why do we need to buy an additional pack?
7kWh is too small for any real use.
Probably yes, cause maybe they are up to 1mw….the one i am taking about are the new 6+ mw, 140 meters high, at full speed that wind turbine wing`s blade produces 84db of noise( at theory)
Cant imagine what will those offshore 12mw sound like 
On the topic: in the matter of fact here we have a working LiOn capasitor that ballances the wind turbine`s power- was made back in 2013, but its price was a WoW one, maybe after 3-4 years they would become quite affortable and reliable too
The problem with the good old fashioned power grid is that it has to be dimensioned for peak power usage. That may be more than twice the average power usage.
With distributed power generation and batteries it is possible to supply the same power using a much cheaper grid. Also distributed batteries makes it possible to use intermittent power sources much better. Wind and solar. This also means that the need to handle peaks with fossile fuel gastubine driven generators are reduced.
So big, efficient and cheap batteries can be used to improve the already existing grid and also make wind and solar more efficient.
However, I doubt that these batteries are big, efficient and cheap enough.
agreed. I probably use that just charing my 18650s for my flashlights everyday 
???
They are scalable, so you can decide between 7 and 90kWh for the small modules. The big ones are infinete scalable and have 100kWh each…
10kWh is enough for one family, if they don’t heat with electricity…
Exactly, if you have to buy such batteries, then the advantages of solar and wind turbines disappears. Where I live electricity is 0.14€/kWh (About the same in $ ). Beat that with solar/Wind + batteries!
What the consumer actually pays depends on how large the subsidies from the government are. So it is very easy to beat your price with wind and solar + batteries, just give it heavy subsidies until it is cheaper and/or remove the subsidies on nuclear power.
You may have a point, subsidies hide the true cost of electricity.
And don’t forget the infinite cost to store the nuclear trash…it is very expensive to babysit something forever…that is in my eyes the only real disadvantage of nuclear power.
And of course the electric companies will never pay for that…
If power gets more expensive people save it where they can, so the actual costs are about the same…this is what happened here.
Just for kicks lets calculate that for my particular situation.
I have 8 hours each day of 0,05€ cheaper kW/h
Let’s say i install a 7kW/h 3000€ battery to charge during these hours.
I’ll save 0,35€ each day.
I can recoup the cost of the battery in a measly 8571 days, 23.4 years. Meh
If i had solar panels it would make more economic sense to sale the electricity to the provider for the premium it buys it.
Unless you live off the grid there is no incentive where i live to buy such a battery, too bad cause i really like the idea especially coupled with solar panels.
It still might make sense as a back-up in case of power outage. Maybe. I mean, you gotta charge those flashlight cells some way, don’t you?
I would cherish a power outage, i could put flashlights in the hand of my family with the triumphant gaze of the savior, a back up house battery ? are you crazy ?
I looked a new Hybrid Hybrid car, it’s not a Hybrid per se as it’s rechargeable for use solely as an electric vehicle, but it can also run on just a 4 cyl gas engine or a combination of gas/electric like a normal hybrid. The downside? There’s almost no trunk! The battery pack sitting above the rear axle is so large it effectively consumes all available trunk space.
My 5 mile test drive showed an average 154 miles per gallon because the cells were not charged with only 10 miles on the car.
I want to get it for my wife to drive daily, she doesn’t like the idea and flat out refuses the no-trunk scenario.
So, while the technology is improving they have yet to implement it in a savory fashion.
Can’t we just put a wind turbine on the hood of an electric car? As long as you’re moving you’re golden! 
I’m a flashlight guy.
What this country needs is more blackouts.
