Krakatoa edit

Not a very good idea to tackle this first on - good idea to read up on the subject before trying to change the article. Winchester or Simkins books - or some of the online material would well worth a good read - this article has been laboured over extensively - try the material first - then come back later - I would suggest. However others might respond to your query - I would suggest a closer knowledge of the subject first SatuSuro 11:37, 22 May 2007 (UTC)Reply

Some parts of wikipedia are jungle material - you need the guns and nets and accompanyng baggage :) - your point is a valid one - but I cannot answer the question as I am about to go off for hours. Indon reverted your edit - I tried to explain to him but your point has to be checked - its a good one - but - its a jungle out there! :) cheers SatuSuro
The response has been good after all - there is someone willing to listen to you! Excellent we might get somewhere after all :) SatuSuro 15:16, 22 May 2007 (UTC)Reply


Exergy Efficiency edit

Hi Andrew. Before you go making large changes it might be good to put up something about yourself (my own home page is not a good example) so that people can how you are. As for your proposed changes, I like the way the original article has energy efficiency included it gives me a clear idea of how they are different to one another. My feeling is that it would benefit from a concrete example and flow diagram. CheersSholto Maud 11:03, 18 June 2007 (UTC)Reply

I've just now had a look at energy efficiency. As I noted in the discussion of that article, I'm a little confused by the use of the term, "useful work". I believe that this has some relation exergy, but I'm not sure. It implies there is both useful and non-useful work in an energy transformation, but does not give symbols for such. I've just made the following diagrams. Perhaps you could use these in the explanation.? Sholto Maud 00:20, 19 June 2007 (UTC)Reply
