Is any of this even cost effective yet? - Page 23

You mean 2 AAA batteries in series. Pay closer attention. The circuit
range is 3 to 50 volts. This circuit drains a fully charged car battery
in a about 20 to 30 minutes.

But does it work?
Granted, it puts pulses of curent into the grid (From the point
that the triacs trigger, until the line voltage rises above
the DC input voltage). BTW: it apears to me that the triacs
are an overkill.  Simple SCRs would work as well.
But will your electric meter properly measure the power you
are sending into the grid?

 
I've been looking for an opportunity there since the 70's. Plenty of
others are too, but they don't invite attention to promising work
until they need an investor. I talk to them at second-hand dealers'
shops, searching for equipment.


Serious chemical or biological engineering is extremely difficult to
impossible at the home inventor level because of EPA requirements and
the cost of the equipment. I have a degree in chemistry but don't
touch it at home.

Turning oil into methane requires a cheaper source of hydrogen. If we
had a good one we would be making gasoline from coal.

BioDiesel equipment is appearing in the second-hand market if you are
interested.

I don't have a degree in anything.

Two or three times a day, I chemically process raw
material using various Maillard reactors.

You cook too?  :)


I don't understand.

The folks in Michigan indicated that the residual fats (as in
veg oil) top the list of methane producing feedstocks at 600
cubic meters per tonne.

Properly designed digesters are self-heating so why is an
additional source of cheap hydrogen necessary?

I'm more interested in converting energy from my garbage.

Bacterial methane production wastes about half the raw material as
CO2. That is too inefficient if the feedstock is as valuable as
processed vegetable oil, not so bad if it's agricultural waste or
manure. Energy production is mostly driven by the economics of the
materials rather than technology.
