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:

Welcome to five years ago.

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?
