@ sut
if you want a really robust lighting system for an (at the
turbine light) then LYNX's idea of an in line transformer
lighting a standard Led bulb is a great idea.
Or you can just wire the 12 v winding directly across the
alternator, it lights at a lower rpm that way.

i'm playing around with this mini yard lamp circuit with a small
joule thief circuit/charger an ran into the same experience an
same questions you had sut did same thing also i found it was
the solar panel size an output of the device one solar cell
1.25x1.25 the for 1.5 v battery.. other 3x3 i put both 1.5 in
parallel it on a larger panel size yard light... an out put was
doubled ran both lights an charged 3.5+ or - volts ran both 2
small led in series an it would charge 2 AA batteries also it
was a larger circuit board. it had small 3 transistors an a few
resistors an a few capacitors .in short i ran it all on
artificial light today ..i experimented with a magnifying glass
to increase light intensity it works both ways..
now i'm looking at a buck booster to increase power supply for
stronger light for continuous oscillating light /looped
light..... solar lighting an charging..circuit..
an very bright 100 watt led light to solar cell refracting off
mirror array... to charging battery an running lights at the
same time..indoors?.. you willneed to kick start ...it works...!
or eliminate the battery all together an use charged capacitors
being switched on an of just before depletion to keep the
loop/ocillation an running continuous.. in a self feeding loop
circuit .....i see you guys use buck booster with rectifiers for
regulating current dc volt for running lights on the wind
alternators.. an for for trickle charging the batteries ... i
want to go grandiose in the solar field..
has anyone experimented or tried this?
...! just an idea an experiment... i quote an experiment
HTML https://www.youtube.com/watch?v=-kWps5Wpbzo
this would drive my
light..an give voltage variables...you still need a power supply
such as batteries or(super) capacitors
i need a booster to run ...a) one larger led lamp 100 watt or
less to be determined? for larger scale model ...self looping
generator....2)led light to solar cell panel... loop
lighting/self charging system ......Indoors.. not outdoors!
2 problems that lamp gets very hot on 100 watt led so it
requires heat sink...i may not need that much light...been
trying to magnify light intensity depends on how may volts i
want/amps i need.. i can liquid oil cool the 100 watt led but i
doo not think ineed that much for a few or sinle 100 wat solar
panel.. it is not efficient 100 watts is a lot of drawing power
consumes to much energy...i want to run unless an be
efficent/cool an safe... i can run in series an increase from
12v to 24v ...36v
what do you think..inquiring minds want to know.. ???
*****an we are not talking a few amps this is dangerous an in a
test phase. i suggest that extreme caution... be used..it is not
for the beginner..**** :'(

Not sure what the overall goal is. Can you summarize in two
sentences what you are aiming to do?
If you are trying to run a light that shines on a solar panel
that recharges the source, you will find that each link in the
system has an efficiency. LEDs are about 80% efficient, solar
panels about 20-30% and circuitry about 80%. Energy will
quickly be burned off as heat, lost to the surroundings as light
and vibrations.
Lidmotor has some good videos on YouTube on continuous ambient
light circuits. Not much light, but these do run indoors.

yes, i keep hearing it from my cousin the physicist professor,
you are correct..no free lunch.. have to produce more energy
than what you get back
thus.i would kick start solar using high energy light, trying to
break the law of physics..as they say..i just thought a
magnification input like a Hyperradiant Fresnel lens applied to
super high efficient light system surrounded by mirrors would
recreate enough power to oscillate a self charging
Perpetual_motion light system...

Try it, refine it and find something new. It is amazing how
much energy is around us that is considered useless. Adjusting
the use side of the equation can make a lot more possible.

Nope, Nada , No way. Nyet. No loop. Best you can do is get some
radio active stuff and first paint your solar array with radium
or some other paint that glows when hit with gamma rays. then
pile on some radioactive stuff to make it glow and use the power
from the solar cell.
