Do you think it would be more efficient to replicate algae refineries so many times? I think if algae is that productive it would be grown in high sun areas and refined at a few central locations, then shipped to “gas” stations.

I know that misses the “locavore” ethos, but is this about imagery and intent or about reality?

The concept is interesting to me. (I’m a civil engineer, so maybe the whole alternative energy thing naturally grabs my attention.) Things like odor, though, make me wonder about how land developers (who often own those malls) and towns would feel about an industrial-esque use in a commerical area. Not that zoning is permanent (it can be changed), but I wonder how that use would affect converted big box stores that once served as anchor stores to smaller establishments…

Good idea, but I would hope that the bio fuel era is short lived and replaced by direct electric vehicles soon. Bio fuel is still for an internal COMBUSTION machine that burns oxygen. I would like processes to produce oxygen.
There are other crops that could be grown that could contribute such as corn, wheat, fruit trees, etc.

Great idea, but wholly unrealistic. Algae production would need to be an order of magnitude higher to be possible as a distribution alternative.

Example:

Wal Mart (the world’s largest retailer), currently has approximately 589,299,000 square feet of retail space in the United States. This includes Supercenters, SAM’S Clubs and their Neighborhood Markets. This is 13,528 acres. Using the above optimistic figure of 15,000 gallons per acre per year, converting ALL of the Evil Empires retail space would yield 202,920,000 gallons of oil. Let’s just call it 203 million for rouding purposes. Assuming (an unlikely assumption) it’s a one to one conversion oilage to usable fuel, that still leaves all of this retail space creating LESS THAN HALF OF ONE DAYS USE OF GASOLINE (378 million gallons per day, per the DOE/EIA http://www.eia.doe.gov/basics/quickoil.html). Hardly a long-term solution.

Well Mr. Smarty Pants Jhunt, we could just stack the algae and grow it that way. How many times? Ten? Twenty? It’s producing 556,000 gallons per day. That is several orders of magnitude less than needed to replace demand.

Stack the algae one hundred times. Take over all the retail space. It doesn’t yet add up.

That said, I hope this takes hold. This technology is promising, if not yet economically viable. And it’s a damn sight better than growing fuel out of stuff we eat. I suppose my overarching point is, there is no one solution that will solve rising transportation costs, climate change, sprawl or resource scarcity. No more panaceas. No magic bullets. Collective action and collective solutions will be necessary.

To the young among us: We shall live in interesting times.

Algae can be grown in open or closed systems. They don’t generally smell bad when growing. As long as the waste is handled, afaik there shouldn’t be an odor problem.

As I recall, these kind of biofuel facilities need to both grow the algae, and “process” the algae. His designs only show the growing portion. a critical step is missing here. The issue of Processing, would make the place a scent, and noise nightmare, and cause a net energy loss through the entire project.

and yes, wind turbines, located such as this, would be more decorative than functional.

Wouldn’t these produce a bad smell? Especially in the Texas heat?

There is too much air turbulence near large buildings to make wind power generation feasible as pictured.

Unless Craig Venter’s no doubt patented, genetically engineered, oil-secreting algae are used, the oil has to be extracted from the cells. This takes energy.

The retail space would house a low-fat Algaburger grill.

Biofuel may be a great alternative energy solution, but converting big box stores to powerplants doesn’t address the main issues with big boxes: they are too low density, waste space, and are a huge eyesore. Mixing in these places with retail won’t remove any need for the giant parking lots, won’t eliminate the trashy architecture, won’t be any better than in the long run. I don’t know about alage in great detail, but why not put these places below ground under new construction sites? And we certainly don’t need huge signs that say “ALGAEX” all over american cities.

ah, bio-fuels that don’t compete with the existing food supply. i’ve been reading about the use of algae in this role maybe just maybe it’ll work. existing oil companies like shell are investing in researching the possibilities.

if it was to be generated locally, the big box store space would certainly be an option, so maybe this idea isn’t as outlandish as it might seem.

i’m a bit curious as to the “retail” section though. seems a little tacked on. not trying to dismiss it, just trying to understand what it is there for. just as a kind of acknowledgement that the retail space would have to be rebuilt *somewhere*? also think that a bit more attention to aesthetics could be paid.
