It Makes Enough Cheap, Non Polluting Energy To Power a Home ... - February 22, 2010, 02:14 PM

Those two blocks can power the average high-consumption American home -- one block can power the average European home. At least that's the claim being made by K.R. Sridhar, founder of Bloom Energy, on 60 Minutes last night. The original technology comes from an oxygen generator meant for a scrapped NASA Mars program that's been converted, with the help of an estimated $400 million in private funding, into a fuel cell. Bloom's design feeds oxygen into one side of a cell while fuel (natural gas, bio gas from landfill waste, solar, etc) is supplied to the other side to provide the chemical reaction required for power. The cells themselves are inexpensive ceramic disks painted with a secret green "ink" on one side and a black "ink" on the other. The disks are separated by a cheap metal alloy, instead of more precious metals like platinum, and stacked into a cube of varying capabilities -- a stack of 64 can power a small business like Starbucks.

Now get this, skeptics: there are already several corporate customers using refrigerator-sized Bloom Boxes. The corporate-sized cells cost $700,000 to $800,000 and are installed at 20 customers you've already heard of including FedEx and Wal-mart -- Google was first to this green energy party, using its Bloom Boxes to power a data center for the last 18 months. Ebay has installed its boxes on the front lawn of its San Jose location. It estimates to receive almost 15% of its energy needs from Bloom, saving about $100,000 since installing its five boxes 9 months ago -- an estimate we assume doesn't factor in the millions Ebay paid for the boxes themselves. Bloom makes about one box a day at the moment and believes that within 5 to 10 years it can drive down the cost to about $3,000 to make it suitable for home use. Sounds awfully aggressive to us. Nevertheless, Bloom Energy will go public with details on Wednesday -- until then, check the 60 Minutes sneak peek after the break.

I saw that chit for a quick sec last night. Pretty legit...the key is making it affordable enough for everyone to use.

Well, he said the 64 plate home power unit should come in below $10K per unit.

Throw in government clean energy incentives to homeowners / tax credits for switching over which will probably take 20% off the cost - or roll the cost into a mortgage on a new home and it amortizes out to probably $30 bucks a month.

I know I'm going to do some research and buy stock when the co. goes public if I think it's a good investment opportunity.

Well, you can only poke but so many holes until it just becomes economically unfeaseable to do it any longer.

What I'd be interested in, is seeing how much this tech weights and if you could install a bank of them in a car with a small hydrogen or natural gas tank for the catalyst fuel.

It could be an alternative to the Li-Poly batteries in cars.

Come on Heist you know me better than that.

Is this any relation to the game Bloom Blox? Very similar. And that same is fuggin awesome.

Yup, it's the Bloom Box. I didn't want to say it because I didn't think anyone would know what the hell I was talking about.

I was actually tipped onto this project last year by an old colleague who worked for Grid Point. I couldn't believe what he was telling me and said I couldn't say anything because of a bunch of NDA's but told me to keep my ear to the ground.

So....

It's a "fossil fuel + oxygen" using electric generator.
An oxidizer that connects the oxidized surface to electrodes.

Now we just have to waste some more energy delivering fossil fuel to the places which use this thing, and we'll be set.

Ah, not so fast grasshopper.
It runs on MULTIPLE fuels.

It can also run on Natural Gas, Bio Gas, Solar or Wind as the other input on the the oxidation process.

And when running on Fossil or even Natural Gas/Bio Gas, it uses HALF the amount required to generate 1KW of energy as it would in a fossil only generator.

Compare the increase in efficiency with the need to physically deliver fuel. Not for free.

I'm just unimpressed because of the whole fossil fuel bit.
We're irradiated by enough solar energy to give something like 100 watts per square meter.




On an unrelated note :

The whole solar/wind thing... I haven't watched the videos yet, but it reads like a reporter's mistake.

It's a closed box, i don't see how light has anything to do with it. And wind? Really?

You don't oxidize light... And by definition, you don't oxidize air.

Unless the 'air part is optional', in which case, wtf...

this thing makes only makes conversion more efficient (than burning, i assume). you're still limited by two things: the original source of the energy and transportation of the fuel.

solar is limited by the area, weather and the efficiency of cells, pumps
wind is limited by area and weather
biofuels are limited by land and the fossil fuels we use to make nitrogen fertilizer
methane from garbage is limited by how much trash we throw out.

even if the above is not an issue, it has to be more efficient to truck a large amount of the fuel to a power station and transmit AC power to each home than it would be to truck a small amount to each home individually. unless you get gas from the city. but then your bill might go up since everyone will want to buy gas.
