Tesla Wants to Build a Battery for Your House

[nomadh]

The mass public is stupid and you can sell them anything. Ask Obama he knows this well.

These AL batteries may be moving along pretty fast. They look possibly low tech enough that if they release some more details we may even somehow be able to make a decent homebrew. If grapheme can be made with scotch tape and a pencil????

This shows it working for a cell phone while flexing. Safe and functional even when a nail is hammered through. Charges in 1 min. 7 times more recharges than Lithium.

Unless its just another Obama sylendra lie

I just read an article where they are using refurbished Toyota Hybrid car batteries for a solar / battery system in Yellowstone.

I wonder what type of cycle life they will get out of them.

Toyota Batteries

That is cool, I see the Nissan Leaf batteries on ebay. Someone is recycling them. I think they are a weird voltage.

Key point "Researchers from Stanford University"

Interesting but to get from research to the sales floor usually takes much longer than they are suggesting.

What about the new upcoming aluminum battery tech that's going to put lithium out to pasture it seems.

Just to add some FUD into the decision.
hate to buy a 10 yr battery 2 years before the 1/5th price 25 yr battery comes out.

Interesting research. Almost as good as the liquid metal (Ambri) battery that is being investigated at MIT. Still too soon to get excited about either.

What and when would people use as a gage to consider this a valid concept ??

I would have to see it being real, sold and used in a home environment along with some solid data on cycle and DOD cycle similar to what Trojan posts for it's batteries.

There is someone in Hawaii that is "testing" an Aquion battery system. While that battery technology looks promising there are a lot of questions to how long it will last and how deep it can be discharged.

In my book it is too soon to tell if either battery is yet able to meet the expectations of people that own a solar pv system (grid tie or other).

[Willy T]

See it on the market and in use for a year or two - then it is more than chatter.

Thats reasonable. I agree and other should also.

As I mentioned in another thread, The Tesla battery is not yet ready for prime time, based on the existing cost and lack of proven cycle life.

IMO it is not a good investment on any level.

You got it but it sure got Musk's name in the news - which is what he wanted.

Here $7,000 will get you about $90 a year in a CD at current Interest rates, not even worth the effort to drive to the bank. Over 10 years no one knows.

Here you can get 3.6 CD over 60 months, which is not a lot, but basically I was talking in general when people talk about there free power from stand alone systems.

With this battery and talking about using it to store power then sell it, if Im on the right track,

( assuming you alraedy have panels etc) 7k for this battery unit which is new so may or may not produce as expected or last 10 years, inverter, panels, controllers may fail in the 10 years life cycle so those costs need to be considered, government policy can change quickly.

Or put that 7k in a managed fund at moderate risk, can reasonable be expected to return 10% over 10 years.

If one was looking to invest 7K which is the most likely to give a ROI.

[Willy T]

True. What use to be a good way to invest, CD's have a pretty poor ROI.

There are other ways to invest where you can get more return but as you know the higher the rate the higher the risk. The trick is finding one that is good.

Funny how back in the 60's I had a savings account that got me 5.5% and I also got a set of glassware with only a $100 deposit.

CD's are not all that good, I did once have some 15% cd's in the late 70's, early 80's, but things were crazy.
