Any help you guys have on improving the website so people don't immediately jump to 'scam!' would be a great help.  We need people to see the simple elegance of the solution, not worry that its a scam.

To improve your web site so it looks less like a scam site:

1) Redo your "team" page so it looks less like a teenage gamers attempt to be cool.

2) Sort out what distributed/grid computing has to do with anything.  One example from your web site (http://www.3xergy.com/wp/concept/)  

"The concept innovation proposed is an appliance that is designed to generate heat from a silent, self-contained computer processing unit which acts as a node(s) in a larger distributed grid computing network. The appliance will send a portion of the computational needs locally to common devices such as tablets, entertainment / gaming consoles, and personal computing, and a portion of computational needs globally as part of a distributed cloud computing network."  

What on earth does the above mean.  And why do you keep mentioning distributed/grid computing?

As a general comment the sentences on your web site are too long and convoluted.  You need to rewrite it to use simpler and clearer English.

3) Remove all those graphs that seem to have no purpose but to look impressive.  For example what does your device have to do with a graph showing the percentage of people in single dwelling houses.

4) Stop taking in this thread about "absorption cooling" and using "heat to create cold" as if the second law of thermodynamics does not apply to them.  The efficiency of extracting heat energy from a small temperature difference to drive refrigeration is extremely low, 5-10% with say a 50C difference.  It does not matter whether you are generating electricity or driving a refrigerator, the same laws of physics apply to the amount of energy you can extract from a temperature difference.

5) Make more realistic prototypes.  Don't have passive boxes with tubes that go out of the box and then immediately back in again.  At least describe in detail what the parts of the prototype are doing.  Otherwise it just looks like any water cooled PC.  Even better show the prototype actually doing something useful, making ice or steam or whatever.  A cup of coffee would be nice.


**Thanks for the feedback - its good stuff... except for #4.  We're talking about a minimum temperature difference today of > 100f to ambient which is more than enough to run a single or double effect absorber.  Remember, this thing is running at 180 to 200f right now (with off the shelf parts!), that's more than enough TD to regenerate desiccant or run an absorber.  The ideal range for the absorptive refrigerator is 180 - 200f, if you go above 230f it actually looses efficiency and starts to break down the refrigerant.  The plan is start building chips that hit 210 to 250f.
