Posted on the BLP website today is the following statement:
“On July 31, 2014, BlackLight Power closed on $11 M in private equity financing that was oversubscribed by $1 M.”

I have actually had some answers to my questions direct from Randell Mills.
Apparently the "solid fuel" is a slurry which is driven through the cell by rapidly rotating roller electrodes. These recycle, recharge and compress the fuel and feed it into the cell. Apparently there needs to be enough fuel to cover a 30-second recharge cycle, so this amounts to about 150 kg for the 10 MW cell.
If you refer to the specs, this solid fuel has a density of 5 g / cm³, this means that there has to be 1 litre of solid fuel slurry being pumped through the cell every second, equally divided into 2,000 "aliquots". And remember, if I might be forgiven for mixing my units, the actual "fuel cell" only has a volume of 1 cubic foot.
As for the heat issue, this is all dealt with by forced-water cooling which is built into the off-the-shelf PV cells. Apparently there are units in the field that deal with this sort of waste heat, so it's no problem at all.
For reference, this is a 53 kW concentrator photovoltaic system at 500-suns intensity:
While Greentech Media has observed Demi Moore's law in c-Si progress, Sabnis asserts that M-J solar cells are more able to harness a Moore's law cost and performance progress. He notes that Solar Junction can get two kilowatts from one 4-inch wafer under concentration at 1000 suns and could produce 200 megawatts of power from its relatively small factory floor if fully populated with equipment.

Since we know Mills powder can produce the light at the required intensity,

Thanks for posting the announcement.
I don't believe in the mythical "hydrinos" that their technology was supposed to be based on, but I thought this was interesting from their link:

Companies do make photovoltaic cells without using hydrinos, so now I'm wondering what kind of photovoltaic cells they're talking about. Still, if an investor wants to invest in a photovoltaic cell maker, and there should be some good technologies to invest in coming up, I'd still advise staying away from any company talking about "hydrinos", like BLP.

We do not know that at all, that is a claim he makes that has not been properly tested...

You keep repeating this as if it's going to magically make all of the third party university lab tests disappear from existence.

As for the 5g per cubic centimeter, that's not the actual amount of fuel that gets discharged at any one time.
Documents call for 200 mg x 2000 Hz of fuel flow for the 10 megawatt version across 10 cm diameter rollers, see page 60:
www.blacklightpower.com...
So they need to move 400 grams of fuel per second (24 kilograms per minute) or 12 kilograms for a 30 second cycle. However, this is still an overestimate because once the fuel is exploded it weighs less because it has no more water in it. I think a half kilogram slurry per second is easily within the realm of possibility.

Their fuel explodes at 50,000 suns intensity in the millisecond range with the same spectrum as sunlight.
The system works by continuously exploding fuel to drive a solar array.
Cranbury, NJ, USA -- BlackLight Power Inc. announced Wednesday the successful testing of a new energy source. The company has successfully developed a prototype power system generating 50,000 watts of thermal power on demand.
The company is presently in discussion with various engineering and manufacturing firms to to prepare this 50 kW unit for commercial production.

I have a quick question about the videos...actually one of my kids had this question, and I'm kind of shocked that the simplicity of it didn't dawn on me earlier.
If the device is producing light at 50,000 times the intensity of the sun...how is it being recorded?
Even the highest end cameras struggle to record the less than 1 sun intensity we receive on good old terra firma...well, without special lenses, that, based on the appearance of those around the box, are not being used.

those are lathe motors in the box, attached to grinding wheels? a spot/tap welding rig in the background and a mechanics led lamp on top of the box with an extraction pipe inset and black smoke from the grinded metal, steel judging from the colour of the sparks.
