Apart from the ppt presentations that will soon be available

through ISU energy webpage here are my notes through these two weeks:


Prof. Daniel Lincot referred to energy payback time or energy reimbursement: the time required for any energy producing system or device to produce as much energy as was required in its manufacture. Today we spent water to have energy when renewable energies don’t! But there is also a matter of toxicity depending on the chemical elements used in solar cells but its always a question whether its better to have a safe process (e.g. use of high toxicity elements in the production with the ability to recycle at end-use than depending on nuclear power which is ‘a completely not recycling process’.


Mr. Louis Palmer went around the world with his solartaxi (info: http://www.solartaxi.com/) and through this experience he is in favour of the renewable energy practises implemented in Asia (e.g Mazdar city* - cooled house with the use of car tires in Kuala Lumpur / Malaysia) – against the energy policy in Australia and initiator of ZERO RACE (info: http://www.zero-race.com/). He calculated that a corn field of about 100 m x 100 m (one hectare) can give biofuel for 36.000km distance but what if this corn field in the U.S.A. was covered by solar panels? Approximately the energy produced could charge a car for about 2.500.000 km.


Prof. Sigurd Wagner mentioned that ‘by the trapped light we live’ and that most important for ozone is the water vapor and then the carbon dioxide but there is an effect in different wavelength!


Dr. Nicole Mathys, is fun of NUDGES & the relative literature (info: http://www.nudges.org/).


Prof. Robert Pitz-Paal, head of the solar research department at the German Aerospace Agency (DLR) believes that DESERTEC (info: www.desertec.org) is a political level decision. As it was a political decision between France, Egypt and Nigeria to call all nations into a ‘UNION FOR THE MEDITERRANEAN’ he mentioned. He also referred to the following projects:

- MED-CSP Concentrating Solar Power for the Mediterranean Region- http://www.dlr.de/tt/med-csp

- AQUA-CSP Concentrating Solar Power for Seawater Desalination - http://www.dlr.de/tt/aqua-csp

- TRANS-CSP Trans-Mediterranean interconnection for Concentrating Solar Power - http://www.dlr.de/tt/trans-csp


Dr. Henner Kerskes spoke about a European funded research - new4old – New technology for old buildings (info: http://www.new4old.eu/) and explained in detail the T*SOL, a simulation programme for the design and optimisation of solar thermal systems (info: http://www.valentin.de/index_en_page=tsol_pro). Orientation (Socrates first mentioned that...), construction and material used are the three most important elements for a building as far as solar utilization is concerned. Interesting project, funded by the 6th Framework Programme is NEGST - New Generation of Solar Thermal Systems (info: http://www.swt-technologie.de/html/negst.html)


Prof. Louis Schlapbach, strongly in favour of sustainability presented the advertisement of F-CELL car: ‘The primal element of all things is water – all things come from water and all things return to water’ Thales of Miletus (circa 625 – 547 BC.). The most important thing that we should never forget is that there is NO NEUTRONS IN HYDROGEN!


Prof. Rolf Wustenhagen is in favour of ‘the energy you don’t use is the most environmentally friendly one’. For Greece as soon as administrative process are initiated and clearer, it is expected to attract in future more the interest of international companies.


Prof. Franz Baumgartner wondered why we speak about climate change when we don’t change our everyday life; He referred to Yukinori Kuwano, who in 1989 spoke about a Global Energy Network equipped with solar cells and international superconductor grids (The GENESIS Project).


OUTLINE: Greece is a country with abundant sun but no high costs for electricity like other – mostly central – EU member countries…maybe that’s the reason why we don’t care about grid parity, e.g. the point at which photovoltaic electricity is equal to or cheaper than grid power and is achieved first in areas with abundant sun and high costs for electricity.

* A planned city in Abu Dhabi - United Arab Emirates, being built by the Abu Dhabi Future Energy Company with the majority of seed capital provided by the government of Abu Dhabi. Designed by the British architectural firm Foster + Partners, the city will rely entirely on solar energy and other renewable energy sources, with a sustainable, zero-carbon, zero-waste ecology. It will host the headquarters of the International Renewable Energy Agency (IRENA - http://www.irena.org/).

Thank you for your hard work to collect and organize, to share with you a lot about the fashion thing, and this is very useful to me.
