Perhaps in can use a homemade ignition coil with separate ground to get amps out of the primary.
That's not hard to do.

I think center tapped to ground is the way to go. Ignition coils are center tapped I think

I think many if not all car ignition coils are a type of autotransformer (not 'auto' as
in car, but 'auto' as in self). This means that the primary winding + lead is connected
directly to the secondary winding. I'm not sure if all car ignition coils are made like
that however.

Also, someone said previously that if details of a device are posted in the public domain that the
device could still be patented by someone else. That is not correct. Once the details of a device/invention
are posted fully in the public domain the device can not be patented, assuming the patent examiner
is made aware that the details of the 'invention' were previously disclosed in the public domain before
a patent application was made. The reason for this is because patents are supposed to protect new,
never seen before inventions, but if the details of an invention are disclosed in the public domain before
a patent application is made then the invention is no longer considered 'new' and 'not previously seen before'.

All the best...

"public disclosure" on the internet is often not identity-related
as far as the u.s. patent office is concerned.
In reality, posting on this site grants the site owner more rights
than the actual "inventor", who would then be obligated to prove
his/her identity.
Since most of us don't use our real names here, this task would
be difficult.


Given the 1-yr time frame for filing:
Virtually anyone reading this information could (and sometimes do)
file for a patent.


If the inventor wishes to claim his/her legal rights to the technology or application
They are responsible for the financial burden of doing so.
This includes legal fees, filing fees, investigatory costs, etc.

As it pertains to automotive ignition coil (non-ic type)

The Commercial Use clause in U.S. patent law is all inclusive
and by far the best way to ensure the device stays unpatented.


This can be as simple as powering a single piece of equipment
at a company building.


Anything from powering manufacturing equipment to a desk lamp
could be construed as "commercial use".


And by such, the device becomes ineligible for a patent under U.S. law
