maxmaximus Posted October 22, 2012 Share Posted October 22, 2012 See my edit above...where on the website does it say 1000 tonnes a day? Purpose/application of the 1,000-tonne-a-day plants Come on then science/math boffins, how much energy would one get from a 1000 tonne of petrol. This is what I found 1000 tonne is 1,000,000 litres. 9.68 KWH per litre 9680000 KWH which is 9680MW which is 3 times more power out than went into it, so it must be wrong.

No boffin needed..You're comparing apples and oranges..A kilowatt hour is different to a kilowatt..one is energy the other is power..if it took a day ie 24 hours using 3 gigawatt to get your 1000 tonnes then the total energy input is 3 gigawatt * 24 hours = 72 gigawatt hours or about 8 times more than the energy you get out..

This plant does take CO2 out of the atmosphere so it would be a bit better if they use waste CO2 is used. Link to comment Share on other sites More sharing options...
PeteMorris Posted October 22, 2012 Author Share Posted October 22, 2012 If the first law isn't a fact then why do we not see examples of it being broken everyday... ? Genuine question... I don't have the answer to that...I never said I did. You're asking the wrong person. Maybe one of the professors doing the reseach? Link to comment Share on other sites More sharing options...

Energy is measured in joules, not watts - power is measured in watts. A litre of petrol is about 44MJ - so 1000 tonnes is about 61TJ all told. Supply 3GW for 24 hours, thats 3GJ per second, so 260TJ of energy supplied. I did the same calculation much earlier in the thread and got the same result.

truman Posted October 22, 2012 Share Posted October 22, 2012 For what? In the post of yours I quoted.. Link to comment Share on other sites More sharing options...
Obelix Posted October 22, 2012 Share Posted October 22, 2012 Of course I do truman. Closed minds because of basic laws I can't accept though. Those who keep quoting the inescapable first and second laws of thermodynamics, and can't accept that there 'could' be something other than their understanding are stuck in some sort of dogma. Wrong again. Read up on the scientific method. Link to comment Share on other sites More sharing options...
maxmaximus Posted October 22, 2012 Share Posted October 22, 2012 In the post of yours I quoted.. It’s in the post you quoted, I got 400MW out after you pointed out my earlier error, and 3000MW went in so as you say it’s close to 8 times less out than went in.
