Conversations from the Cruisers Forum regarding Questions and Answers from Technicians associated with DBK Solar

 
 
  #283
Regarding DBK and their new JIL 3000, I have been involved in about a dozen email exchanges with them so far, and its frustrating. I am a real serious potential customer, building a new home on a tropical island, and interested in solar. All I can get is very vague stuff. They are telling me that they are using RF from the sun to power and amplify the 700 watts from the panel up to the 3 kw....uh...wait a minute.

The most I can get is that its NEW technology, and there are people out there who don't want this technology to succeed. For my new home, I am getting basically "just give us $ 28,000 and don't worry...."

So, I am talking to the Kyocera rep in the DR.

Interesting -- Obviously, what you do is your business, but when I hear stuff like that I tell them, first, show me your work, then I'll decide whether I show you any of my money. Sounds like they don't want to show you their work.

well I don't want to take up too much space here, but here's some typical exchanges:

(me in boldface)
I did a quick Google on the DBK 3000 watt panel, and ran across a number of skeptics, to be blunt. The question that keeps coming up is:

50in X 40in = ~1.3 sq m
1 sq m of sunlight is roughly 1350W of power on average at the distance of the earth from the sun BEFORE accounting for atmospheric losses and WITH consideration of a 90 degree angle of incidence.


and
It's pretty clear that even with a 100% conversion efficiency, they couldn't generate more than 1200W with a panel that size (50x40"), to say nothing of the fact that the shadow produced by the panel indicates that they're not getting max solar to produce their "3000W". To say nothing of the lack of a load. Got to be a hoax.

I am sure you are used to hearing and reading this stuff. How do you respond to them?

(DBK)
"

I forgot to tell you in my last email. Our panel gets 700 watts from the sun to our panel and the rest is electronic amplification to bring it up to 3000 watts.
We have a patent on the system, it is our this is not a HOAX in spite of what the skeptic's are saying.

NOTE: THERE IS NO PATENT FILED

(Me)




Well, I am no expert in these things. But I do know that in order to amplify something it takes power. Where do your amplification devices get their power?

Ah, is this somehow tied in with your fuel cell operation? That would mean that the yearly maintenance costs would mostly be replenishing a fuel cell?

Or am I way off base?

(DBK)

 "We use the sun to power the amplification process, the sun wave*  is similar to rf wave. New technology for solar panels.

The maintenance is to check out the whole system. Our mission is to protect you and the invention, there are powers that would not like to see this invention get out. So, our details are limited."

(Me):
So, if I understand, you are pulling something out of the sunlight other than the photovoltaic? in other words, the sunlight amplifies itself?

Are you going to have technical observers at your upcoming demonstrations?
I would be most interested to see an unbiased third party's write up of it. Someone other than DBK employees or dealers.

Please keep me informed."

(There were more exchanges, but that's as technical as they've gotten with me.
I aint gonna buy one just yet.)

Is this what they are talking about.

 

Title:

Radio frequency monolithic power amplifier layout techniques
Document Type and Number:
United States Patent 6844783
Link to this page:
http://www.freepatentsonline.com/6844783.html
Abstract:
Radio frequency monolithic power amplifier layout techniques for the purpose of the invention is for improved thermal and electrical performance of RF monolithic power amplifiers. The inventive device includes the main components of the invention is to exploit layout techniques to improve the thermal and electrical performances. A technique, named input feeding phase equalizer, is invented to achieve better heat dissipating performance. A second technique, named grounding equalizer, is invented to achieve better electrical performance. A third technique, named staggered transistor column, is invented to achieve better heat dissipation performance. The electrical length between the input to the input stage of a 2n-column cells is topologically altered to achieve input feeding phase equalization. The electrical length between the ground to the ground stage of a 2n-column cells is topologically altered to achieve distance equalization. The rows of transistors of a 2n-column cells are staggered to achieve more uniformed heat dissipation.
