In Search Of: An
ongoing article on a subject which will be updated as more information is
collected.
Current Subject: The
smallest usable electrical generator.
I am searching for a small generator that can
efficiently charge a battery bank, is affordable, and can be installed in a
small apartment. The generator must be quiet and can be easily vented to
prevent any toxic gas from building up in the living spaces.

I found this video on line by a Japanese company that is
developing a small 400 watt generator powered by a gas turbine. Their projected
cost when fully developed would be a $1000 to $2000, a bit “spendy” for a home
400watt generator. https://www.youtube.com/watch?v=Al8elCF816g
Solid State Electrical Generator
3/18/2017
“We got a working experimental setup of the solid-state
electric generator. We need funds in order to build a devise for demonstration
and eventually patenting and development of designs for production.” https://solidstateelectricgenerator.wordpress.com
I reviewed the above article which indicates that a Solid
State Electrical Generator (SSEG) is being developed. I had a couple of
questions and some red flags come up as I read the paper.
1.
The paper was written in 2014, why is there no further
developments published?
2.
They are seeking a few 50K to 150K euros for
development and legal costs. If they have a working prototype, that shouldn’t
be an issue?
3.
They are building a 220volt 2.3KW generator. Why
not start with just 100watt battery charger? Once you have proved your
generation method works, you can start to scale up on the sale of the smaller
systems. I would buy a 100watt battery charger.
I’ve
seen this development method before. It works like this: An inventor has an
idea but no funding. He(or Her) needs to eat so they seek funding for their
development efforts. Once they have enough of an operation to sell, they get
more investors to fund their effort, exploiting the current “green energy”
push. Both private and public funds are solicited to keep the dream alive until
they can be fully divested from the operation. The company goes belly up
because the promises made are not financially viable.
I
am warry of these types of generator proposals because the physics behind them
don’t pass the smell test. You can’t create electricity without either a
chemical reaction, a semiconductor “photons to electrons” conversion of energy,
or some mechanical energy to move electrical windings through a magnetic field.

Another
green energy company goes bankrupt- Aquion Energy, a salt water battery manufacturer
goes belly up even after massive government and investor subsidies. The article
sources are online publications listed below.
*Aquion Energy, a
rising star among manufacturers of large-scale energy storage systems,
announced on Wednesday it had filed for Chapter 11 bankruptcy reorganization
amid struggles with fundraising from investors.
*
company said it is in search of a buyer and hopes to emerge from bankruptcy “in
the coming weeks.” It has laid off about 80 percent of its personnel, keeping
only a core research and development team. The company has halted its factory
operations in Westmoreland County and paused marketing and sales efforts,
I have seen
these types of Startup Technologies succeed and fail over my 30 years working
in industry. The script is a worn path starting with an idea for an emerging energy market followed by hyped expectation to satisfy a hyped up crises married with
a political force. Some of these never make it off the ground and die a sudden
death due to poor salesmanship and questionable merits for market value. But
some, like this salt water battery, get some wind behind its back because of
its apparent simplicity and material commonality. With 70% of the planet
containing salt water, what’s not to like about an energy storage technology
that uses salt water.
The electrical
chemistry is basic and fundamental (2Cl- => Cl2 + 2e- ). The sodium in salt
water conducts electrons produced from the reaction with the anode to the cathode
of the battery. But you need a high
volume of salt water to produce enough electrons for practical load application,
~1kw.
The problem
is pointed out in these articles:
**David Snydacker, a
battery expert at Dosima Research, tells GTM: "Aquion's size/weight
per kilowatt-hour was approximately 15-times greater than lithium-ion. Like
other competitors to lithium-ion, Aquion tried to emphasize that size/weight
doesn't matter for grid storage. But all that extra material has an associated
cost. The bankruptcy was probably foretold by the bill of materials."
Dozens more startups are aiming for
utility-scale energy storage working with compressed air, mechanical systems,
flow batteries, and other electrochemical means.
Quite
simply, salt water batteries don’t compete with the other technologies size/weight
per KW-Hour capabilities. That means you just can’t go down to your local
discount hardware store and replace these babies. They would never have got
this far into the market place if it wasn’t for the “green energy planet saving
political initiative”; another words, the energy storage market didn’t ask for it.
**After spending $190 million and making
bold promises, outgoing CEO Scott Pearson had this to say: "Creating a new
electrochemistry and an associated battery platform at commercial scale is
extremely complex, time-consuming, and very capital-intensive. Despite our best
efforts to fund the company and continue to fuel our growth, the Company has
been unable to raise the growth capital needed to continue operating as a going
concern." *But he said the financial challenges of
surviving in this market are “not for the faint-hearted,” requiring “huge
amounts of capital” to scale up and stay relevant.
Do you think Scott Pearson was given
a heads up by Wall Street analysts or maybe his only employees that this was a “pipe
dream” which was not ready for prime time before burning through $190 million? But
with all the hype and government money for the taking, just ride this out
and cross your fingers. It’s living on a credit card; sooner or later the bills
must be paid. That is why the market place is the predictor of which technologies
succeed or fail. If non-political investors are willing to invest in an emerging technology, it must have some inkling of promise. When technological obstacles
appear that are insurmountable, the money usually dries up and invested elsewhere.
This is the free market forces in action.
So for now, salt water batteries are
better left for science experiments then a green energy solution.
