Only time will tell, and I'm not holding my breath.

"Aquion has $27 million in liabilities and less than $8 million in assets."

To me, it sounds like a financial move to stiff a bunch of people out of $27 million.

Actually, the people owed money were SOL as soon as the $27 million in liabilities and $8 million in assets came about.
The bankruptcy process does not put them substantially worse off, but just codifies who gets paid first from the money available.

If you were referring to the entire business operations of the company, it may be a more appropriate characterization, or it may just have involved bad business decisions.

Most startups fail.

No you are not. :slaphead:

why would i take util power and put that into batts. the batts get energy from the solar panels (free), etc.

Solar energy is not free. You pay a cost for the equipment and installation. And you get a certain amount of energy from that over the life of the system. The quotient is called the levelized cost of electricity, and it's going to be a few cents/kWh even if you DIY it.

So, the bulk of my electric bill every month in the summer time comes from running the air conditioner. In fact my bill doubles... Almost triples because of the AC. I've been thinking about putting the AC system on solar power. What information do I need to get about my AC system in order to purchase the correct solar power setup. I'm seeing 400 Watt systems but the description says it will only work smaller devices and such. Where do I find this information?

Don't know if this is any help but I recall a website that had a video of a solar powered mini-split ac unit. It was more a look how he did it then a unit for sale.
 
Wow ,
All These reply's to a OP that does not return.
I don't think the OP is a electrician.

:?

Gee, ya think? :D

Tokamac (fusion generated electric power) has been "quickly approaching" for decades, and it doesn't look any closer to reality now than it did 30 years ago. I think that solar is safe from fusion for the time being.

I agree. I recently read "sun in a bottle" which is a very good read on the pursuit of fusion energy. After reading it, I am quite skeptic that fusion will be viable anytime soon. Even if we can figure out how to contain it, there is still the issue of neutron enbrittlement of the vessel, and extraordinary high costs. Fission's promise of cheap nearly free power certainly never happened.
 
One favourable condition for use of batts is in places (e.g telephone exchanges) where a generator is also available for use during grid down. In such cases generator fuel consumption costing around more than three times utility bill can be cut down during power failure because of availability of solar with batts.

I think more important is the fact that batteries can take over during a power outage nearly instantaneously while a generator will take a while to spin up and stabilize. Batteries are great for a short term lapse in grid power while a generator is better for longer timelines.

interestingly enough, you dont need batts to do this. massive gyro slugs can be utilized and will surpass batt service life by many many years.
so in daytime, some solar energy is added to the spinning slug to add back any energy lost in the bearing system, and with today's spinning technology if you lose input energy the slug can still spin for months giving you time to fix the input side, batts will not last months w/o input energy. you can pull energy out of a spinning slug just like you can with batts, almost instantaneously.

A spinning slug, or "flywheel" is just a mechanical capacitor, and it suffers from the same limitations. As soon as you start pulling energy out of it it starts to slow down, and that reduces the either the voltage available or current available, depending on how you hook it up to the grid.

in this discussion the power from batts/solar/util is to be used locally, not back into the grid.

with lead batts the voltage drops as they deplete their energy, but you can deplete them down to a min voltage. "friction-less" magnetic flywheel is as good as it can get in terms of efficiency.

batts can take a charge way faster than it takes to spin up a massive flywheel, but the batts are way less efficient. saving $$ for some potential energy to be used later, batts are not it.

I'd like to see some quotes for flywheel batteries vs conventional batteries :roll:

Flywheels equipped with magnetic-levitation bearings and encased in vacuum chambers come pretty close.

The chemical process industry has used magnetically coupled pumps for at least 40 years. Their key limitation is the torque they can develop. This is going to limit the rate at which you pull energy from and dump energy into the flywheel.
