My prediction is that somebody is about to pay the price for not learning enough science in school, is going to get ripped off for a humiliating amount of money, and then quietly stop talking up DBK.

So don't say you haven't been warned. Those responses from DBK carry abundant hallmarks of a sales scam.
1. Lots of name dropping and important sounding credentials which can't be verified
2. Lots of scientific sounding buzzwords which to those who recognize them add up to meaningless dribble
3. Stories about how you the customer are privileged "in the know" and are going to make gobs of money from a venture, but for some dramatic reason, no one else can be found in the world who wants the money.
4. Description of the "technology" consists of valid technical explanations of how the success of the technology would benefit you but no explanation of how the technology would succeed. e.g. "Your new money tree, if amortized over a ten year period, compounded annually, will provide the cash flow to pay down your debt in half the time, allowing you to buy two houses instead of one." Great, but where did the "money tree" come from again? "We'll have to explain that later. We don't want our competition to know. First give us a $40,000 deposit."

"Power Amplification" is a twist on the meaning of words. You don't amplify power. You use power to amplify something that lacks power. Saying that a solar panel only receives 300 Watts but is "electrically amplified to 2000 Watts" is the electrical equivalent of saying you can "amplify" your rain water collection system using sprinklers. Think of all the weight you would save if you didn't have to carry along water! Instead take this special dehydrated water and hydroponically amplify the amount of water by rehydrating it.

Hi guys and gals,
I just got back from visiting DBK solar last night after spending the day there. They really won’t have product out the door until the first part of next year. The unit I tested looks good, weighs about 50 lbs and is soundly built. (I used to build conventional panels myself back in the early 90’s) the first test was done at 10 am in the shade. The warehouse faces west, the panel was rolled up to about half in and half out of the warehouse door with the sun at that time still in the east creating a shadow from where we were, out into the parking lot about 30 ft away. I was surprised they were going through the demonstration anyway! They hooked up the panel to a battery and an inverter. Putting a tester on the battery I found it was at 12.7 Volts. Putting it on the panel I found it was putting out 166.6 Volts. This was going into the inverter and into that we plugged in 2- 1875 watt hair driers that ran full blast. In the afternoon at 3:00 pm the test was repeated in full sun. The panel overloaded the inverter putting out 225.6 volts. They proceeded to cover the panel with a blanket about 2/3’s. That still ran the hair driers at full blast. It seems the panel will easily put out over 4000 watts in full sun and over 3500 in the shade. It will put out some even at night. (short wave radiation is converted as well) They are guarantying 3000 watts output at 20 years down the line.
More later. Steve Merrill. 702-274-9818

What was the size and type of panel - is it a glass or a semi-rigid?

are they making any forecast on price or delivery?

that sort of power delivery promises a lot, but is going to make the regulator's job difficult, and how do they dump the unused power?

Steve, What where they using to step down the voltage to 12v. I'm assuming that the inverter was in-line after the battery to convert 12v DC to 110v AC.

Maybe we hope that we haven't heard the last of DBK solar.

To get this much power out of something so small (relatively) has the ability to change sailing as we know it... even at 5k a pop..
