New battery technology is on the way. Does ego have intentions of making the source of their power beyond belief last longer than belief?
Or is the eventual need to replace the battery too large a part of the business model?

Kind of like mpg's with the Automobile and big oil?

Haha, yeah, we might see the start of big battery!

Interesting, for sure, but I'm not sure such a technology would benefit a typical battery powered application very well?

If we assume a 1000 cycle useful life span, and that a battery mower's battery gets used on average once a week or so, a battery would last almost 20 years!

In a cell phone that gets charged every day, a 1000 cycle life span would give you close to 3 years of service, so I could see a chance to improve there. However, at 100,000 cycles that translates to 300 years of service!

For the mower battery you'd be looking at close to 20,000 years of service!?! The planet we're living on in the year 22,016 might not even support the growth of grass, or we may have invented self-cutting grass by then. :-)

For most applications and since batteries tend to degrade with time, I think researchers would be better focusing on the time aspect as much as the cycle life.

A battery cell that can be charged hundreds of thousands of times certainly would have applications, though. Think of the batteries in hybrid cars that are recharged under braking and discharged on acceleration. If a hybrid car cell was cycled completely from full to depleted 100 times a day, a 400,000 cycle life cell would last about 11 years! That would be a huge improvement over current batteries, which have to be very large in order to limit the depth-of-discharge they see repeatedly.

Or it could be useful for replacing supercapacititors which can be almost infinitely cycled but whose capacities are very limited.

To be honest, several huge "breakthrough" battery research projects make the news every year, but few if any ever get to the mass manufacturing stage. Creating a one-off lab sample for testing is one thing, but scaling the technology up for mass production and making it robust enough for real world applications all while being cost competitive? That's something else entirely. :-)

Blue, you are obviously a shill for big battery. I bet you have closets full of AAs and your smoke detectors never beep. You poor nickel cad, you evil lith Lord, I will not fall for your lies, your lead is acid. Tell big battery that their charge has failed in his task.

(Full disclosure, I am not a battery conspiracy theorist. I'm just a guy who likes to use puns and doesn't care who he hurts in the process.)

Oh yeah, well I'm working on a power generator that can draw energy directly form the EM field. It could supply thousands of watts forever.

So burying a big copper wire in the ground pointing north to south? Capturing the magnetic field of the earth? Or something else?

Something else. Something similar to what John R. R. Searl is doing. Besides, eventually with such a method if that even works, that will eventually drain Earth's magnetic field entirely, and it therefore could not run forever.

it's the end of the world... i just want a battery that lasts a summer. hell if i can get 2 then i'm happy... bought a 15" weed eater and just received a blower that uses the same battery. NO need for the quick charger.. i tend to drink cold beer and mow at the same time so i don't mind waiting...

TAT, if you run the field in sequence via chip then you can increase the spin "if" your thinking of creating a continuous field with a wheel? Interesting

Are you talking about field weakening?

Hmm, also was just thinking of gathering static via a pole the Tesla way.
