Default Tesla to announce new revolutionary product Apr 30

I read an article on USAToday the other day saying Tesla was going to announce they were going to introduce a "revolutionary" new product at their press event on April 30.

Rumour has it will be home storage batteries and this will be their big push into consumer products. Interesting if true. Depending on sizes, could be of use to us RV'ers.

Thoughts?

Hmmmm...im wondering if the new Home Storage Battery theory is true, then would these new batteries be a push towards getting closer to being able to have trouble free full size AC / Heater units in RV's and to be able to power most appliances? ( I was reading an article about a couples rv experiment project on Lithium batteries ) http://www.technomadia.com/2015/02/livi ... ry-update/

I don't know if I would call the Technomadia bus RV experimental. It was a commitment. It has been running that way for 4 years. Maybe a first somewhat in RVs but the yachting industry is way ahead. BTW, our Advanced RV has the same type of batteries as Technomadia from Elite Power Systems in Tempe, AZ only we have 800ah bank to their 500ah. Either one is no where near close to full-time air conditioning but our bank can power all electrical systems 120v AC and 12v DC all the time without ever plugging into shore power. On our last trip we went from February 23 to April 1 without ever plugging into shore power and we cooked our dinners on an electrical induction cooktop and microwave/convection oven and brewed our coffee with a Keurig. My wife used her electric hair curler and blow dryer almost daily. We have no propane and no Onan generator.

Roadtrek has two Sprinters out on the the road with 1600ah of lithium ion batteries. I know they had a 24/7 air conditioning goal but not a lot has been said about their performance publicly. They are considered experimental. My Advanced RV is a production model.

We'll have to wait until Apr 30 ...............

It would be nice if it was something that we could use in our RV's.

Ahem...... a potential game changer?

Apparently it can only produce half the voltage of lithium, but it's other characteristics may make that an acceptable issue. They say they can probably improve the energy storage capacity, with some tweaking.
Just thought it was interesting.

Sounds promising, but I doubt this is ready for a commercial product announcement.

Musk has some old interviews if you google search where he talks about the future is not batteries, but capacitors. It would be amazing if they've actually developed a viable capacitor for this kind of product. That would really be a game changer.

They have been working on aluminum based batteries for a long time, as the article states. It will be interesting to see how well it develops. The low voltage is probably not a huge issue as you just need more cells to get to a specific voltage. They said they got to two volts, and lead acid are at 2.1 volts.

If it looks to be real, Musk will probably be in on it very quickly, or at least commenting on it heavily. Good find.

A prototype is always a good start.
It may or may not amount to anything, but at least someone's looking into it and seems to have had some success. Sometimes these things just need a lot of persistence to happen.
I was thinking about the voltage issue, and if you can get half the voltage of lithium for a quarter or less of the price in the same sized package, you'd be ahead of the game. Based also on discharge/recharge rates being faster and more efficient. However, I'm not a chemical engineer. Heck, I'm not even a railroad engineer.

Interesting and exciting. Fun too.

From the utility grid I pay:

10 kWh $1.10
7 kWh $0.77

but that is every time I use 10 kWh or 7 kWh.

The word "easy" comes to mind. This introduction makes it easy to get some or possible all of your power needs from batteries. Easy could lead to wider adoption of the technology and invite competition which should lower the cost ...............
