Aquaponic Solar Greenhouse
an Integrated Food and Energy System (IFES) for sustainable food and energy production
Page 230. November 2013
Why?Why do we need improved growing systems?
Page 330. November 2013
We all are sitting in a very comfortable Space Ship – so far!
Page 430. November 2013
In Space Ships smoking is strictly forbidden!Smokers:
Page 530. November 2013
Smoking can have bad consequences …Air Pollution and CO 2 - Increase:
Page 630. November 2013
First Symptoms are already clearly visibleGlobal Warming:

Climate change destroys growing spaceIncreasing temperatures:
Page 830. November 2013
Positive feedback loops are further raisingthe global temperature …
Methanhydrates are instable:

Peak Oil:
And, limited resources are jeopardizingfood security!
Page 1130. November 2013
The current decrease of cheap oil productionis a very severe danger for food security!Oil production forecast:
Page 1230. November 2013
Slowly, also the oil companies are waking up …Shell:
Page 1330. November 2013
The price of oil is strongly increasingTrend:
2004
2013
100 $/barrel
36 $/barrel
Oil price increased by 20% per year!
Page 1430. November 2013
The Competition between Food and Energy is forcing this Situation!!Food or Energy?
Page 1530. November 2013
The Food Price is increasing accordingto the Oil Price!!FAO Food Price Index:

A drastic impact on our world societyis expected soon!German Military:

Drying
Processing

No Oil …
No Food!

What?What can we do?
Page 2130. November 2013
Local and autonomous Integrated Food and Energy Systems (IFES) are providing a way outFirst good approaches (FAO):
IFES Type 1:
Physical coexistence –Food and energy plants are cultivated at the same field (example: Pea and False Flax, lat. camelina sativa);
Closed loop systems – By-products and residues are the resources of the following process steps (example: corn, cattle, biogas, digestate back to the fields);
Integrated Food and Energy Systems (IFES) are farm models for the production of food and energy at the same time and at the same place.
IFES Type 2:
Page 2230. November 2013
Interesting Facts!Light Intensity:
The plants require only 250 to 350 W/m²
The sun provides 1,000 W/m²
Too much light inhibits plant growth!
Page 2330. November 2013
A new Approach increases nowthe Efficiency of Food and Energy ProductionCooking Recipe for an IFES of Type 3:
Create controlled environment conditions by minimizing the heating and cooling loads;
Use Photovoltaics solar systems to provide shade and to control optimized light conditions for plants;
Implement Aquaponics to lower the systems heating and cooling loads and to increase its food production;
Use highly transparent cover material;
Expand photoperiod in northern latitudes (light);
Convert surplus solar irradiation direct into usable energy;

The PAR Light Film increases the output of Greenhouses without additional energy demandSun Light Spectrum:
Plants mainly useBlue and Red Light for Photosynthesis,
Green Light is less used!
How to make the Green Light usable for Photosynthesis?
