No, I have not.
Last time I checked, Bloom had not posted those numbers.
I am going off the numbers those experimenting with the boxes are stating. They are much cheaper than purchased electric to run.
""This is just another on-site renewable energy source that we're exploring to help power our facilities," she added. "We have a 400-kilowatt [Bloom Box] installation
on Google's main campus that delivers clean and affordable power. Over the first 18 months, the project
has had 98% availability and delivered 3.8 million kilowatt hours of electricity."
Bloom's Energy Server is a parking-space-sized device that uses fuel
cell technology to generate 100 kilowatts of power using almost any type of fuel
, promising the potential for reliable, zero-emission energy generation.
eBay has been running five Bloom Boxes on its campus in San Jose for seven months; while the company is currently using natural gas to power them, the company's green team director, Amy Skoczlas Cole, explained that eBay has almost finished the process to use biogas to power the boxes.
"First point: The box has a 3-5 year payback period, and fixed energy prices for the next ten years.- Second point: the carbon footprint is 50% cleaner than the grid and 100% renewable.
- Third point: 24/7/365 power with always-on modular architecture. If a box or unit has to be fixed, it will still generate power, like a server farm."
I spend 1200$ a year on electric. Using the twice as efficient statement, that means I can run my house on 600$ a year, or about 300 gallons of propane for the most expensive path. If Biogas or natural gas is used, it is even cheaper.
I am quite sure I could recover 300 gallons of methane off a septic system optimized to produce methane, rather than optimized to prevent it. If not, I could still generate the lion's share of the needed fuel.
Guys, I don't know much about sailboats, but I am not dumb. I don't post other peoples claims about such things without researching them. The Ebay statement of 3-5 years to recover costs would be pretty close. On the Google server campus, it took 18 months, according to a statement a year ago. That statement is contradicted by the quotes I just posted.
Using Google's statement that they had produced 3,800,000 million kilowatt hours does not jive with the paid off in 18 months statement I read in an earlier interview, so I am assuming that the initial cost was less than what has been settled on today as the price
, or that the early estimates were too optimistic.
At the current rates here in Missouri, they would be on track for a five year pay off also. Using the rates Ameren is attempting to have approved, about half of the initial investment is covered by the first 18 months use.
Worst case seems to be a 50 percent reduction in current costs, 50 percent reduction in pollution from generation, and a five year pay off on the equipment
Back to my home. At a savings of 600$ a year, the pay off on a 3000$ box is dead on the five year estimate, and that is using propane, one of the most expensive options. That is not using LED's or any of the other energy savings methods to cut my needs. In a remote
location, or on a boat already optimized for energy conservation, I am quite sure a septic system could provide the fuel needed.
That 50 percent cheaper and 50 percent cleaner estimate is a worst case scenario, using the most polluting and most expensive fuel options.
Do a search and run the numbers yourself.
By the way, some of the numbers do not make sense, so there is a disconnect somewhere. They say a 3 to 5 year payoff.
4 boxes times 700,000 = 2.8 million. They say the generated 3.8 million KW h with thoise four boxes in 18 months. 4.5 years, 11.4 million KW h still puts you well outside the cost of purchasing
that same amount from Ameren.
.09 times 11,400,000 = 1,026,000$, at Ameren's proposed price.
Either Google paid significantly less than 700k for each box, or power costs a lot more in Sunny Cal
than it does here. Using the 700k published price, we would be talking closer to a ten year pay off here.
The math works for the home unit.
