A Perspective On The B Type EESD - Robert Murray-Smith - Any issues?

   With solar we're getting to the point where utility companies are introducing
  severe capping on grid-tie installations.
    An obvious answer seems to be a storage system. I can't ever see big mileage
  in capacitor derived systems due to the unfavourable discharge characteristics.
  A storage battery can supply a fairly flat output curve which is ideal and the big
  problem has been degradation. I came across Sonnen battery the other day and
  was amazed to see a 10,000 cycle life quoted. Can this really be true???

Forget about RMS-there are bigger fish to fry.

I would like you to have a look at Mark Dansies latest thread,and let us know what you think.

Time to leave all the !will never work!stuff behind,and look at something that dose have potential.

What do you know about this ion transfer stuff?

Osmosis normally lets water molecules through a membrane and not the ions.  Simon on Revolution Green said that normally the water molecules are smaller than the ions.  So it sounds like the membrane is doing the opposite.  I am not really qualified to talk about this stuff so I will have to have a wait-and-see attitude.  So it's similar to waiting and seeing for yet another battery "breakthrough."

You will know it is real when you can go on Amazon and order a new replacement battery for your cell phone that is 10X the performance of current batteries.  Or perhaps if some new battery technology must work at a different voltage, then you can imagine new cell phones being designed for the new batteries.

The thing to keep in mind when talking about batteries is that the market is already there for the picking.  So perhaps one day a battery breakthrough will be real.

As for the difference in using a cap or battery for grid support, I dont find issue with the caps voltage variance in comparison, as there will need to be inverters to send power down the line from these support substations. There are many even small dc-dc converters out there that work with a wide range of input, so the caps could work well.  The biggest battle between caps and batteries would be energy stored per cubic inch.

There are some stories that come out periodically about a new batteries, but then they die out and never heard about again.

Had read some time back that a new car batt was in the works where instead of both + and - plates being made of lead, that using carbon for one of the plates produced a better battery at nearly half the weight.  Havnt heard about it since. That would be big for lead acid batteries in the battery market.  Like my electric bike, I run what looks just like a typical 12v 12ah battery with heavy push on terminals, but it is 14ah. Get them at Batteries Plus, $55 ea but I use 4 for 48v, and you save about $70 in the quantity of 4. So about $150. About 11lb ea on the bike rack. If they were nearly half the weight it would be closing in on a similar power lith pack that costs $600 to $800.
Ive met many people that got bikes with lith packs and when it goes bad they dont want to put in  another $700, sometimes within a year.  Me, $150 for 1 to 2 yrs of every day ridding, Ill live with the extra weight for now.

Lidmotor made what seems to be a battery using aluminum foil for both plates with a salt water soaked paper towel between. No voltage when measured, but then you charge it and it acts as a battery. Im guessing the charge makes changes to the plate surfaces. Probably car battery lead plates are precoated electrically, as some batteries come without the acid in the battery, some motorcycle batts, and when you put that acid in, it shows charge.  If the plates were just plain lead there would be no initial charge when you put the acid in.

Just rambling.
