Renewable Energy Sources Conference

The 15th November Estonian University of Life Sciences held their 9th coference on "Investigation and Usage of Renewable Energy Sources" in Tartu. I attended as part of the university, but mostly out of curiosity.

The conference had leading researchers in renewable energy from serveral countries and officials of the Estonian ministries. There seemed to be a strong focus on the countrys vast unused biomass and its applications. Estonia have a lot of unused agricultural land after U.S.S.R. occupation (3 hectar per inhabitant of which 200.000 hectar is abandoned), and a though they are not raping their huge resources of trees, firewood is a common heating source, and has been for hundreds of years. I could not help noticing that firewood is part of the term "renewable energy", but I did not notice references to the enviromental implications, only the economical rentability.


The goverment did, not supprisingly, bring out that they wished to focus their funding, and welcomed researchers who volunteered to state outdated or fields with too low cost-benefit. They also asked for more structured or exact research, since the last 30 years in some fields had given little clarity of the situation regarding renewable energy. On the other hand researchers gave an official plea to the goverment for guidelines to what they should do. Little news there I guess.

The Ministry of Economic Affairs and Communications gave some interesting data on the status of different renewable energies, but focused on the use of forest resources (biomass conversion, direct energy production and waste uses). I could not help raising a few questions on heat pumps. I asked if they had considered using deep sea water for heating Tallin like the plan in Stockholm? It had not been considered, but they had noticed that the last 5-10 years the sales and use of heat pumps were doubling every year in Estonia. They could not answer why most of the deep ground energy heat pumps were rejected in most cases in Estonia, but speculated it could be due to protection of ground water ressources.

I know that Tartu already has a great initiative that makes heat and ventilation to a house - basically ground heat that does not use electricity. But it is one of these initiatives that has an modest inventor with humble ambitions. So I think very few will see this technology - like others. I will write about the Geothermal Air-conditioner later.

Several fine initiatives were presented at the conference. The best in my opinion was a German initiative by Michael Wachendorf and his team, who focus on using the increasingly abandoned German farm lands. The abandonment is against EU regulations (which is worth a thought), but the farming is no longer financially sound in some areas. So in their initiative they harvest the wild plants growing and converted them into biofuel. I liked this project because it not only tries to produce sounder energy, but also invoveld a growing problem caused by a changing culture.

Estonia is third in Europe (following Lithuania and Finland) in use of renewable energy resources (including firewood) with a set goal of 5.1 % for 2010; a goal that has already been surpassed. Unfortunately this kind of statistics, I think, probably would not change the fact that Estonia is also one of the most polluting countries in EU. So I left with the feeling that the focus was on "renewable" rather that "greener" or perhaps just "sounder" energy. No leaping for Estonia, but small safe steps with the crowd.

General introduction - Catch-22 of Innovation


When I entered the natural sciences I could not get the thought out of my head: How many amazing, perhaps revolutionary, inventions continuously are lost due to habits and rules of society, and why?

To give a little introduction, I would like to give an example of such an invention.

When I was 19 years old a local Danish TV program showed a short documentary on Erik Skaarups wave energy converter, he named “Bølgehøvlen” (now named WavePlane). The program planted the first seed of doubt in me whether truly innovative achievements are getting a place in our time.
Erik Skaarup explanation how he as a home inventor came up with the idea of harvesting wave energy in his bathtub made me smile, but it was the opposition his idea met at the most obvious investors (like the Danish government) that dazzled me! The depressing story of how he went from door to door of the investors was long, even with self financed test proofs of pilot models. The potential investor I remember the best was the Danish Ministry of the Environment who argued they did not find it necessary to invest in wave technology since they had wind power technology well developed. A paradoxal statement considering Danish politic has preached green energy and innovative solutions as part of up-keeping the national welfare and work places for decades. The story have not changed over the last 13 years from what I can read from the company website (www.WavePlane.com) who now has most investors in Norway and bases in Australia, Japan and USA. Time will tell if Danish investors made fools of themselves.

Now I have found that hundreds of incredible inventions and inventors, through news but also first hand, who never get to change the world for the better. And why? Is it the patent laws? Eccentric behavior? Lack of scientific proof? Lack of economic understanding from the inventor? Lack of understanding of the impact of the invention of the investor? Or is it because we, as civilization, just can not handle more than one revolution at a time (currently being the IT era)? I think it is all of the above. And in this blog I will try to give examples of these points of view.

To make myself understand this paradox, I created two groups of inventors: the Alchemist and the Scientist. I may be a son to a father of the first category, but am officially working as (and by the rules of) the latter. An Alchemist is a term I use in lack of better because it best fits the personal approach of discovery (home inventors, but more) in lack of better, not to mix up with the medieval magician. It is my opinion that these two groups approach inventions from opposite angles. The Scientist has to skeptically build all his discoveries on theories already established. Theories that are our best bet at describing reality, but far from do so.
An Alchemist plays around, discovers something works, believes in the invention, but then meets the modern age demand of nearly anal demands for documentation. Often this creates a catch-22, that few normal people have time or temper to satisfy. The result is that the invention dies with the owner, in the patent office or in the drawer.

If innovation and miracles are what we need to solve the 21st Century’s challenges, maybe we need to reevaluate our approach to discovery and the space we allow true originality. Welcome to my blog!
