Assuming the fuel cell doesn't degrade. But at 1/8th the cost, you could just about buy a new one instead of overhauling it once a year!The lifecycle costs would be much lower.
Agreed, though the longevity and maintenance issue is also an assumption you are making. No, it doesn't have as many moving parts, but it does burn hot, so I'm not inclined to just accept that it will last as long or work with considerably less maintenance.Cyrus said:The question is if he is able to make fuel cell cheap.
He says he wants household units - which don't exist - to cost $3,000 for a 1 kW unit (which he says will supply a household, but really won't: they'll need at least 5 kW). It actually costs $700,000-$800,000 per 100 kW. $7,000/kw / (($700+1100)/2) = 7.8xIf so, it will be a breakthrough in mass-marketing the technology. This thing will cost about $3k per household. How do you figure it is only 1/8 the cost?
That doesn't paint a very rosy picture of the economic outlook.References:

And still, they haven't gone much below the 500-600C threshold set by the ionic conductivity of YSZ.Topher925 said:SOFCs have been around a lot longer than 8 years, they just haven't become so commercially viable and cost effective until about 5 years ago.

minger said:Have their been any independent research regarding the actual efficiencies of this thing? I seem to recall reading/hearing something from Google where they basically said, "We don't care how efficient it is, it's good PR."
I think I heard somewhere in that interview (watched it last week, sorry) that he was seeing ~80% efficiency.
If it's more efficient that the ~60% power plant -~8% transmission losses, then I'd might be on board. As everyone has agreed on though, price...

I think I heard somewhere in that interview (watched it last week, sorry) that he was seeing ~80% efficiency. I'm not sure if this is for one component or fuel in/energy out, etc. The thing is that this thing produces CO2 just like any other fossil fuel generating device, so the whole "green" thing really only applies if it's more efficient.

That would be very surprising. It is true for a small gas turbine (the type that would be competing with this product), which will run around 30% efficiency, but large gas turbine power plants tend to use a combined cycle (using the waste heat to run a steam turbine) and achieve around 55% efficiency. http://www.gepower.com/prod_serv/products/gas_turbines_cc/en/downloads/GEH12985H.pdfChi Meson said:Assuming that what the 60 Minute piece said is correct (not always a safe assumption), the boxes at the Google site used only half the natural gas compared to what would be used to provide the same power via the grid. That is at least the way I understood it.

Chi Meson said:I don't think it's a scam. The science is valid, it's more a case of whether or not the energy/money saved will make the initial investment worthwhile.
Well he's gotten a huge amount of investor capital on a promise of a revolutionary product. If it turns out his product is not fundamentally different/better than other similar products on the market, his investors will be pissed.Topher said:Its most definitely not a scam, although some things stated in the videos are a bit misleading.
TheStatutoryApe said:Wow. I almost thought it was a joke at the beginning.
I thought that wireless energy was pretty much a no go though? Too much waste.
I didn't hear a claim of breaking even financially. One of them said they had saved $100k in electrical costs, but that to me just means exactly what it said and nothing more. At $700k per unit, and with multiple units installed (and they didn't say how much they paid for fuel...), they are a long way from breaking even financially.Proton Soup said:it'll be interesting to see where it goes. I'm as skeptical as the guy in the video. so far, it sounds like Ebay, et alii, only save money with these because of government subsidies.

It's not a lie. A payback calculation looks like this:Proton Soup said:i guess the question if whether he's talking about a time value of money calculation, or simply making an outright lie.
Well that part was also misleading. That's $3k per kW and that's nowhere near enough to power a home (I live in a townhouse and my air conditioner alone is 4 kw) unless you have it running 24/7, with a large battery bank to store the excess at night (like with a solar plant). I don't think that's the preferred setup.and they're certainly trying to get investors excited. one in every home, times about 128 million homes at $3k a pop is $384 billion just for the residential market.
[snip]what i see is a lot of hype. and hype will feather his nest just fine.
The commercial market for energy is a little smaller than the residential. The industrial market is twice that size: http://www.eia.doe.gov/emeu/aer/pdf/pages/sec2_4.pdfi guess commercial would push it well over a trillion.
Chiro said:As for wireless energy there is a physicist named Dr Konstantin Meyl who demonstrated wireless electricity in an american conference some time ago. His work has been replicated in several other universities. I can't remember his website off the top of my head but if you want to verify my claims google Konstantin Meyl and you should find his website.
I suspect that was just bad writing/reporting. I watched the whole thing and didn't see any other referenes to it.TheStatutoryApe said:The wireless angle is what set off my crackpot detector. I did not notice more than one reference to it though I did not watch the whole thing.
No, you are correct, for the most part. It works fine over very short distances, in the range of milimeters (ie, my electric toothbrush). Beyond that, it isn't viable.Am I wrong in assuming that wireless energy is too wasteful to be viable?

I'm not sure it is a real useful concept, though, since you have to attach a rather large coil to the back of the phone to use it (it snaps-in to a device similar to a plastic cover).
Agreed. Credentials or not, he certainly talks like a crackpot. That may be a result of the position he's in, though: crackpots and advertisers are basically the same thing.waht said:I never bothered to read up on the bloombox, but since it's getting so much attention I thought I'd give it a second chance.
First red flag...
Fourth red flag: When there is no peer review, you can still become your own crackpot despite the credentials. They have been secretive for eight years, yet there is no secret. I'm in awe they were able to maintain the status quo for so long and attract the new investor wave who think green energy will revolutionize the next century.
What is wrong with that ? Suggesting that american people use too much power, and implementing a reasonable reduction in the design of his box looks to me like a very good idea.waht said:Second red flag: flashes a fuel cell in front your eyes and says this one will power a European house, take two and will power an American house. LOL.
The huge box was not for a private house obviously.waht said:Third red flag: Claims it will replace power grids, and shows you a huge bloom box housing that won't fit in most people's basements. Most people don't even have a basement, nor lawn.
There is actually a secret, you do not know how the coating is manufactured. An important question in this business is the durability of the product. My understanding, if the initial product was design to provide oxygen to NASA astronauts on Mars, there is a possibility that the coating is actually quite robust. Obviously, only time can lift doubts in this regards.waht said:Fourth red flag: When there is no peer review, you can still become your own crackpot despite the credentials.

I certainly agree with that.waht said:And that's because Collin Powells is on it, doesn't make it credible.
Topher925 said:He didn't invent anything. He's just using a different material than a lot of other companies and a slightly different design (apparently, electrolyte support instead of anode support). SOFCs have been around a lot longer than 8 years, they just haven't become so commercially viable and cost effective until about 5 years ago.
rewebster said:I'd buy one today if it was in the 3k-5k range---and I think the 'wireless' implied may be 'off the grid' (not connected via transmission wires) -not 'no wires for its own use

It took three years of development to produce the first in-house version of the Bloom box, and in 2006 the company shipped its first unit to be tested at the University of Tennessee under a contract with the U.S. Department of Energy. After two years of testing, the company shipped the first Bloom boxes to corporate customers in July of 2008 – twenty Fortune 100 companies in all.
russ_watters said:I'm wondering what the intelligence of the typical multi-million dollar venture capitalist is. Do they respond to such things? I know if I was going to invest a lot of money in this (and if I demanded info and all I got was a used-car sales pitch, I'd be upset), I'd want to see a real business plan. After all, he's got working prototypes. What, exactly, is its efficiency? What did it cost to build? What enhancements are you working on? What are your prospects for streamlining manufacturing?

I do not really disagree with you, at least I think I understand, but I believe no matter how we approach this, it will remain pure speculation. All this noise only leads me to one conclusion : the success or failure will be driven by commercials and communication rather than facts from the data sheets, and as they say : there is no such thing as bad advertising.waht said:I suppose the bulk cost of the Bloom Box are the cells. But fuel cells can get clogged up with impurities that are in natural gas. And hence the efficiency of Bloom Box would go down over time. Factoring in long time needed to pay for itself, it will need maintenance. And if the maintenance is replacing expensive cells, then that defeats the whole purpose.
