For a guy that says he doesn't know much about technology Mr. Doggradio 2 sure comes up with some novel ideas.
It is he who (he who?) started experimenting with solar collectors on a tower for powering the tower, and now again it's he who gives us a whole new way to grab free power, the hot air from all the announcers speaking into their low power contraptions.
In an unrelated idea, which could be related later, I was clearing leaves and other vegetation the other day, listening to KDX CC at 670 on the portable, and got to thinking about all that veg-a-waste we throw away. It could all be converted to energy and used to power little circuit cards and boxes.
Don't short change yourself, Doggradio, your ideas are worth more than 1 1/2-cents.
Bruce's description of the transducer generator is similar to the idea of generating power by the same mechanical motion, but from the movement of the body.
Can't remember exactly when but there was a watch that ran by producing energy from your pulse in your wrist.

Thank you for your comments
gentlemen, regarding the
voice powered transmitter.
That thing has been on the net
for years, somewhere.(?)
I know there has been a lot
of discussion about IDs lately.
Or lack, thereof.
However, for a hot air voice
powered Part 15 radio station,
I'd go for:
WCO2, HOT AIR RADIO

P.S. If we put it on Part 15.227
27.185, which I think is CB channel
19, and had about a thousand people
SCREAM in to it, maybe some truckers
would hear it.
This kind of talk has reminded me of a CB idea in the 1970s when I thought our neighborhood should promote everyone having a CB station so we could have some kind of community security communications, and I think I even applied for a license for that purpose, which I think was still required at that time.
There wasn't a single neighbor that was the slightest interested so I sat there with a CB transceiver and listened to a nearby highway and just a few blocks away a self-styled preacher with a strong linear amp spent most of his day screaming biblical passages as if the whole future was at stake.
That guy was too far ahead of his time, as the future didn't go at stake until now, forty years later.
It's too bad that didn't work out for
you Carl. But in a lot of places it
did, for a while anyway - when the
fad was at it's highest in 1976 to
1977 or so.
I remember riding with a friend in his
car. We were driving around doing errands,
or something like that.
He had a CB in his vehicle. He picked up
the mike and said, "Can anybody give me
a 10-36?" A voice came back immediately
and said "2:15!" which was the time of day.
I remember being very impressed by that,
even though there was a clock in the car.
I had a lot of fun on CB talking to him. We
were about 3000 feet apart. (Still living
at home with our parents.) We were both
using junk CB radios that people had thrown
out. Those radios didn't have 23 or 40 channels.
They had a few channels with plug in crystals.
It turns out both radios had channel 5, so we
used that.
It was a lot of fun. My callsign was KBJK-4953,
and I still think it's cool, even after getting
a my ham license.
I don't know the state of the REACT organization,
but I know they did a lot of good things. I
wonder that they are doing now?
Best Wishes,

Yes, Doggradio 2, now I remember that there were CB call letters. If I can find my old license it will be interesting to see what they were.
Well, but what should we do about Big Talker 2, a SW transmitter especially for this 26mHz region under Part 15.
Many posts remind us there are no DXers listening to these frequencies.
But if there was an egg, maybe there could be a chicken, before which there would have been neither.
Carl, if you have the time, I think you
should try to make one.
I'll be back with some more comments on why,
and maybe even how(?)
Bruce, DOGGRADIO STUDIO 2
Well Carl, the only thing I can
think of is:
I like all the other Part 15 websites,
but HERE, at Part15.US, there SEEMS to be
more experimentation that has not been tried.
Such as the 13.560 rig, or my CC experiment.
(I'm not trying to brag - those are just
the only two examples I can think of right now.)
A 27 MHz Part 15 transmitter is really just for
fun. And as RFB said, it could be a good VSU link.
"Very Sort Hop."
I have used my 1973 Radio Shack Space Patrol
walkie talkie to listen to the telephone
answering machine in other parts of the house.
I've also used it to let me know when the
washing machine has stopped.
That walkie talkie is only legal now if you
collapse the transmitting antenna a bit. It
puts out too much energy to comply with
Part 15.227 unless you do that.
I know you have been interested in that 26 MHz
SWL band. The field strength level permitted there is
pretty low. I suppose you could build a transmitter
for that range, but it wouldn't go too far. Also,
the crystal would be quite a bit of money.
If you had a collection of vintage tube shortwave
receivers, a 27 MHz transmitter would be good for
transmitting station audio through those radios.
Again, if I ever get that 13.560 transmitter finished,
it will be just for my friend across town.
The 1690 Part 15.219 rig and the CC rig (if it ever
happens,) would be for a general audience.
If my friend lived closer, he might be able to
hear a transmitter operating under the 27 MHz
Part 15 rules, but he is too far away.
To me, it's really about the fun. If I had the
time, money, and the real estate, I would be
experimenting on the 160 to 190 kHz band, that's
for sure.
Best Wishes,
Bruce, DOGGRADIO STUDIO 2
Since you mentioned it, my first CB call back in '64 was KNN-7431. I had a Lafayette HB-115A. The TX was crystal controlled (up to 8 crystals) and the receiver was tunable, channels 1 to 23.
My second license was KBPG-0551 as there was a lapse of time between the two. The FCC dropped CB licensing shortly after obtaining the 2nd license at which point they said to just use your "handle" or your initials and zip code prefixed with a "K"; KRF-44221.
SCORE: I just found and bought a Lafayette HB-115A on Ebay to complement my museum of childhood gadgets.
