Fish from the Sky with Vegetables. Globe / Hedron a Rooftop Farm.

GLOBE / HEDRON is a bamboo greenhouse designed to organically grow fish and vegetables on top of generic flat roofs. The design is optimized for aquaponic farming techniques: the fish’s water nourishes the plants and plants clean the water for the fish.
Using this farming technique, GLOBE / HEDRON is optimized to feed four families of four all year round.

GLOBE / HEDRON is designed to be manufactured and retailed at a low cost. Easy-to-set-up units can be combined to scale up food production capacity.

Using a geodesic dome, the load of the fish tank rests on the frame of the greenhouse and is redistributed to a larger surface. Because of this design, the aquaponic farm can be housed on more roofs without any structural building adaptation. The dome structure is designed to be built with bamboo, so that it is biodegradable and organically farmed.

GLOBE / HEDRON is designed by Antonio Scarponi / Conceptual Devices in collaboration with UrbanFarmers.

So wonderful I wish it was already true. When you say it feeds four families of four at the cost of a city car, that’s the cost of buying and installing it? How much would the maintenance cost?

2 scarponio 17/02/2012 at 00:33

Thank you for your comment. It is hard to reply your question since we need to prototype to really know. But yes the cost of it should be close to the one of a city car. To run it the most costly would be time. Since it should be self sufficient energy wise. The idea is that an elderly person can run the farm for instance so to involve a local community (imagine someone belonging to one of those four families).

3 narf7 07/05/2012 at 22:36

What an amazing concept! Its great that you have considered the age of the person who may be using this product and ensured that it is appropriate for all ages to work in. Love the concept…the idea and the amazing thought that went into it. I think that you are both paving the way for green urban gardening and doing your bit to minimise the effects of global warming. Cheers!

4 scarponio 08/05/2012 at 14:09

The honest truth is that is very hard to know precisely the production quantities. That is a rough bet. Although the design is scaled for four family. Production wise it depends on the climate and many other factors. So practically that is why we are crowd funding the first prototype. At the moment the production is an assumption based on other (more traditional) projects experience.

5 Sylk28 12/05/2012 at 18:43

I really like this project! I’m sure that it’s a good idea. I just want to know. Do you think it will be easy to keep alive fish and vegetables? Isn’t it a little bit hard to managed for non-specialist people?
Thanks a lot

6 scarponio 12/05/2012 at 18:51

If you have learned how to drive a car, you can also learn how to run this system. :-)

The point is that you can also understand the relation between the aquatic world and the terrestrial one. In this sense it is very educative for children.
However no. It is not that hard to operate. Or at least is hard as farming can be.

7 Michelle 13/05/2012 at 18:35

I would think that if you could incorporate a solar panel Or if you could take the fans already on it and somehow design it so they are also creating power for the dome to run the pumps, fans and any lights, it would be even easier to run on a roof PLUS in case of a disaster or power outage you wouldn’t need to worry about losing your fish PLUS it would be more cost effective. . What do you think incorporating these ideas?

8 scarponio 13/05/2012 at 18:42

Thank you for your comment. I give solar energy for granted. I can not imagine to approach such project (or any other project) without it.
Thanks – Antonio

9 Cyrille 13/05/2012 at 22:04

I understand that the plants are nurished from the feces of the fishes, but what are the fishes eating ? What would be the cost of the system in fish food ? Brilliant idea anyway !

10 scarponio 13/05/2012 at 22:14

Thank you for your comment. To be precise, the plants will be nourished by the fish urine. The cost of fish food might depend, also on the amount of fish. I would not considered it a significant cost compared with the over all operational costs. Salad can not be harvested by itself. ;-)

11 Mark Sanders 16/05/2012 at 00:11

Love this idea and hope it does really well.
Just wondering about getting bees in? Obviously they’re needed to pollinate many of the plants.
I see some vents with fans, they get in through there?


12 Jon Connelly 16/05/2012 at 10:54

Great idea. Too bad we can’t read or enlarge the photos…

13 scarponio 16/05/2012 at 15:28

I have not thing about it. This might be a good idea… Or option.

14 Megan 16/05/2012 at 20:41

Would this idea be adaptable in the developing nations fo the world? There are many communities that could use a facility such as this one since it is semi self sustaining.

15 scarponio 16/05/2012 at 22:44

That would be point of doing such projects. But first, prototype!

16 Gilles 18/05/2012 at 21:43

I am always looking to make some projects of interest for myself, and such greenhouse to grow fish and vegetables was already part of future project in my mind, but made somehow differently as I live in Québec, Canada where temperature is not always clement for such project. Actually close to be off-grid, with wind generators, solar cells, and solar water heater, my next step is for self sufficient greenhouse, so let me know development on your project as it is quite in line with what i am looking for, except with inside large size insulated pool to keep temperature even when necessary during long cold winter period with no sun. Looks great to me..and would be willing to get one prototype as well.

17 Green Reserve 21/05/2012 at 15:28

I’ve been looking at a lot of similar ideas and there are a few things you should think about.
1) this will not work in countries that have a winter below zero. Without insulation, this is not too useful above the 45th parallel.
2) From the perspective of we northerners, the fishtank serves a more important aspect of being a heat sink, and heat exchanges should be incorporated to allow the tank to passively collect solar heat during the day and circulate it at night to extend the growing season.
3) the back wall does not need to be transparent, so making it heavily insulated to face north and reflective on the interior is a good idea so the sunlight is maximised.

Good idea, many of us have already thought of (or toyed with) similar ideas – many have already built aquaponics systems in geodesics – but the way you’ve designed this to be a package solution is innovative. I wish you success and hope you cruise around the internet to see how others have done the exact same thing and made it work in the north.

18 scarponio 21/05/2012 at 17:21

Hello there, thank you for you comment. Yes, the north side is actually insulated. The idea is that you can have different settings according to each climate. You can see this in the implemental features board.

19 Cyrano 25/05/2012 at 17:56

Sounds good! you need to factor in troubleshooting: if the tank goes sour; if the fish get fungus; if the beans climb all over the chard. Full, with crops ready to harvest, what does it weigh? How many hours of sun does it need; how many are too much [at what latitude?] I’d buy one if I knew all these things and could afford it, and liked the answers. Have you actually grown crops, and what varieties did you succeed with?

20 Cyrano 25/05/2012 at 18:03

without bees, you need parthenocarpic tomatoes, but broccoli and leafy veggies, roots etc obviously don’t need bees. melons don’t seem probable

21 Antonio Scarponi 25/05/2012 at 18:13

Thank you for your message. It is aquaponics, not magic. To run the system we plan to have sensors that control the water condition (depending on budget), however you need someone who operates it, it does not grow food by itself (yet). In other words, if I was able to answer all your question the we would not be in need to prototype and fundraise. I hope I did answer your question. Regarding growing crops, I am personally growing letuce in my office, look it up on this site about MALTHUS: On the other hand one the UrbanFarmes co-founders, my aquaponic partners, has years of scientific research on the field, you can address them for this questions. Antonio

22 Antonio Scarponi 25/05/2012 at 18:13

Yes. Thank you. We will consider that. Bees are good in the city. Antonio

24 Luiz R. Blumenthal 05/06/2012 at 19:24

What an amazing idea! Should the fish be fed with normal fish food?

25 Antonio Scarponi 05/06/2012 at 21:15

Thank you! Basically you can give them basic fish food. If you are smart you can generate food for them like flys or warms of different type. This is very easy to do…

26 Evan DeRouen 28/06/2012 at 10:15

Hello, we have a non profit for reshaping the world society. We have been looking at your design for this aquaponic system and love the design. We have experience with both aquaponics and PV. We feel this could possibly be a real game changer if deployed as quickly and affordable as possible. Would there be a way for us to acquire the design specs and materials list? We would be happy to help in the development and rapid prototyping process. Could this design be made available as open source hardware? We are in the US and are currently working on development of a non monetary city model where everything is generated on site. I look forward to your response, thank you.

27 piero 29/08/2012 at 02:03

ciao! since you need money to build this prototype, wouldn’t be easier if you start building littler ones, less expensive but still effective, and sell them to families that own property? for example italy is full of families with a little house and a garden where they always try to grow something and they almost always fail, due to the difficulties treating the soil; plus in almost every garden there are bees, so tomatoes can grow without hassle, and the initial amount of water needed can be the rain filtred and stored in a rather big tank, that will also be used for the toilets in the house itself. You’ll figure out something for them not to freeze, like a serpentine.
Spero di aver scritto tutto in un inglese impeccabile (anche se so che non è così, lol) ciao

ps. per evitare che la neve si depositi sui tetti facendo crollare tutto, non si potrebbe stendere una sorta di rete che si scalda facendoci passare la corrente? ho le idee un po’ confuse a riguardo, ma penso tu abbia capito cosa intendo…

28 Antonio Scarponi 29/08/2012 at 08:53

Ciao Piero, grazie, ci sto pensando in effetti. Questa e’una delle ipotesi sul quale sto ragionando. Per la serpentina non sono sicuro secondo me ci sono sistemi più semplici.
In ogni caso ti faccio sapere.

29 piero 30/08/2012 at 10:31

Ciao! Da qualche parte in questo progetto è possibile inserire un generatore di corrente idroelettrico? lo si potrebbe collegare direttamente alla pompa oppure ad un sistema di supercondensatori (i boostcap della maxwell, o gli evercap) per far funzionare le ventole e le luci interne.

prima della pompa si potrebbe inserire un aggeggio composto da una serie di lame che disintegri i rifiuti solidi dei pesci, in questo modo il concime rimane più efficace e la gestione viene facilitata

ho visto il progetto malthus, non si potrebbe creare la stessa cosa per l’esterno? qualcosa di semplice e modulabile, soppalco a due o tre piani / due o tre piani di vasi / soppalco / vasi, in modo da formare via via 2 pettini affastellati, intervallati da grandi vasche per l’itticoltura; sfruttando il fatto che l’acqua debba defluire per tornare nell’acquario si posizionano i generatori in punti strategici per aiutare i pannelli solari

infine visto che ci sono delle osservazioni riguardo il mangime per i pesci, si potrebbe includere nel kit un essiccatore, nel quale versare le bucce, foglie erbacce, lische ecc, ed un tritatutto, in modo da ottenere una polvere che se compattata e trafilata possa essere usata come mangime per i pesci

è divertente come progetto, ogni tanto mi vengono ste idee magari alcune funzionano pure

30 Antonio Scarponi 31/08/2012 at 11:01

Grazie, sono tutte ipotesi interessantissime.

31 piero 31/08/2012 at 20:07

questo è il mio ultimo post per un bel po’ perchè devo prepararmi per gli esami,

l’acqua di ritorno, prima di tornare nell’acquario dei pesci, potrebbe passare in un sistema formato da: un serbatoio / un idrante / una turbina pelton con inverter ecc.

l’acqua (non si sa mai, evapora una parte, una parte viene assorbita dalle piante che crescono) verrà rabboccata dal sistema di riciclaggio dell’acqua piovana

gli escrementi dei pesci si possono portare nelle fattorie in cui trasformano il letame in gas

i pannelli fotovoltaici è meglio sostituirli con quelli termici per l’acqua (se non per i pesci si collega al boiler di casa); anche se CIS sono una truffa, solo che suona bene dire “ho il fotovoltaico in casa, amo la natura la madama e la marchesa”

bon io ad ottobre (settembre è il mese degli esami) vado al briko ok vicino casa e provo a costruire qualcosa….

ciao ciao e buona fortuna per il vostro progetto

36 Falk Fritsch 10/06/2013 at 14:20

reading through the comments section more than a year is gone since the cost for Hedron was given as that of a city car. Given the fact that City cars come in different sizes, has there been put some figures to that statement?
Is there a price for Hedron? Is it for sale already? What is actually the size of the system?
Thanks for any info. would look good in my garden. :)

37 ivania 12/07/2013 at 10:03

when is this product going to be in the market? I’m looking forward to buying it.

38 Antonio Scarponi 22/07/2013 at 09:51

Thank you for your interest. At the moment I am not thinking of developing the project as a product but rather as an architecture. This would allow more customization and lower costs. If you are interested, please let me know and we can discuss this further. Antonio

39 Antonio Scarponi 06/08/2013 at 18:24

Ivania, i am still not sure it will be developed as a product or rather as an architecture. In this case it would allow me to feature more customization and a wider costs range. Please let me know if you are interested in develop one for your needs.

Buongiorno Ricardo,

scusa non parlo spagnolo, ma solo italiano, o inglese. :-)
Al momento sto progettando un esemplare che verra presentato a milano per EXPO la prossima primavera.
Fammi sapere se sei interessato come singolo utente o come eventuale distributore.
La versione che sto sviluppando al momento e’ leggermente diversa e si tratta di un sistema idroponico, senza pesci.
a presto,
