Re: [Vo]:A sound way to turn heat into electricity

Just noticing some real obvious patterns in the alternative energy community. There seems to be a lot of "hit & run," lol. It has some negative impact, and therefore from here after I would like to have people close the discussion by confirming their error. 

Stiffler,
You said,
---
Your idea is viable if we had the ability to heterodyne down from the Thz range with an efficiency that would make sense in recovered useable energy. 
---
Your key word, "if" places nearly 100% probability that you are suggesting my idea would only work "if" we could "heterodyne down from the Thz range." Could you please confirm that you read my reply to your above statement and that you now understand "heterodyne down from the Thz range" is not required to capture appreciable energy from room temperature gradients? 


Thanks,
Paul Lowrance

Hi Stiffler,


On a macro scale all matter contains a sea of temperature gradients. 
View two 15 cent millimeter size thermistors separated by say 1 inch and 
you'll clear see temperature gradients any place on Earth. Such 
gradients is usable energy, even with old heat->electricity technology. 
Such a device does not need to reach THz temperature gradients to 
capture "free energy." In fact a slow reacting DMM is fast enough to see 
the evidence. That in itself is "free energy." Not much, but some 
nonetheless. If you want more energy then make the heat->electricity 
device smaller, and more of them to cover the same area of course.



Stiffler, there is no magic reaction time where such a device suddenly 
captures "free energy" from such temperature gradients. I'm a little 
baffled you would say, "Your idea is viable if we had the ability to 
heterodyne down from the Thz range with an efficiency that would make 
sense in recovered useable energy." Just below twenty THz is merely the 
average blackbody radiation frequency at room temperature. Indeed it's 
probably next to impossible to measure 0.1 Hz blackbody radiation with 
even the best leading edge equipment, but there is indeed easily 
measurable temperature gradients in the 0.1 Hz region. Perhaps you were 
thinking of blackbody radiation. My previous post discussed temperature 
gradients, not blackbody radiation.



This is very obvious and simple physics. Of course it would require 
expensive equipment capable of making such nano size heat->electricity 
devices to produce significant electrical energy flow. Presently such 
devices are not so efficient, but good enough nonetheless. Here's one 
well known company that's about to release such an efficient solid state 
chip -> http://www.powerchips.gi

It is becoming more difficult than every to know what has been and is 
being
researched due to the issue of now 'We Must Sell' our research papers. 
With
hundreds of middlemen resellers of research and the US Government 
wanting to
suppress everything because they are clueless, it is a wonder we even 
have

research left in the US.


We have plenty of bio research, but I think that has a different bent 
if you

look at big pharma.

So my 1/2 cents worth is, what can we give the common man now that is not

under the control of some big corp? The TAPM is one such device as it 
can be
build with some copper pipe and a hack saw, (maybe a few other minor 
thing
:-) ), your 800W/m2 sounds great, but is there that you know of a way 
to tap

it??

No offense intended to anyone, but something must be said about the 
obvious.
Did it ever occur to you people that such a device if made small 
enough and

react fast enough could draw significant continuous energy *anywhere* on
Earth
day and night?  On a micro scale there's a vast sea of significant
temperature
gradients everywhere. On a nano scale even more so. Just a few days ago I
posted
info on such an obvious fact of science.


I'm just baffled how everyone misses the obvious! It is intentional? I 
don't

get
it, LOL. What's going on ... did/do universities play subliminal messages
all
day programming poor students at a young age to never consider such
thoughts, LOL???

Far from a new idea indeed, what is new is that it is moving closer to

being

a viable technology. A thermo acoustic refer has been developed and 
tested

in HOT undeveloped parts of the world and found to work. The device is
placed in the sun during the day and it produces ice, then it is moved
indoors at night and keeps foods cold until the next day. What one must

see

is that there are NO moving parts. The device can be built from material
that is not super expensive.


Something (I'm not aware of anyone doing it yet) is to use this 
device to
reclaim potable water from the air. Granted the load is greater than 
doing
the ice, but it can be done, and is an interesting idea as all one 
does is
get to the dew point and dump the resulting latent heat which with 
proper

design can be used by the prime mover.

Not new indeed, but better than some of the other hair brained schemes

being

proposed by many...

A sound way to turn heat into electricity

University of Utah physicist Orest Symko holds a match to a small heat
engine that produces a high-pitched tone by converting heat into sound.
Symko's research team is combining such heat engines with existing
technology that turns sound into electricity, resulting in devices that

can

harness solar energy in a new way, cool computers and other 
electronics.

University of Utah physicists developed small devices that turn heat 
into

sound and then into electricity. The technology holds promise for

changing

waste heat into electricity, harnessing solar energy and cooling

computers

and radars.
