The Biomass Energy Conversion Technologies - 1342 Words

4.3 Biomass Energy Conversion Technologies Biomass materials can be converted to various useful forms of energy such as heat, electricity and liquid fuels. The technologies used to convert biomass into energy ranged widely from the simple combustion of biomass used for cooking and heating in developing countries to a variety of technologies to generate modern energy carriers - electricity, gas, and liquid bio-fuels. Canada is using various materials including waste and residuals to generate electricity, heat and, bio-liquid fuels (bio-ethanol and biodiesel) (Defra UK et al. 2007). Biomass energy can be used at the household (-10 kW), community (-100 kW), or industrial (- MW) scale. Key biomass energy conversion technologies include thermal and thermochemical, and biological and biochemical. †¢ Thermal and Thermochemical Technologies o Combustion — convert forestry, agricultural and municipal residues into heat and power under environmentally sound conditions o Gasification — convert forestry, agricultural and municipal residues into syngas o Pyrolysis — convert forestry and agricultural residues into bio-oils and value added products o Thermal and Catalytic Processing — convert a variety of new and used vegetable oils; tall oils; waste greases and animal fats into renewable diesel fuels and diesel blending stocks †¢ Biological and Biochemical Technologies o Fermentation — convert the starch and cellulose components of biomass to bio-ethanol o Anaerobic Digestion — convertShow MoreRelatedDirect Combustion Of Biomass For Heat Generation1244 Words   |  5 PagesDirect combustion is the most common way of converting biomass to energy - both heat and electricity- and worldwide it already provides over 90% of the energy generated from biomass.

‘for Me, the Story Is Less a Horror…Than a Larger Than...

‘For me, the story is less a horror†¦than a larger than life gothic fairytale’ (Kenneth Brannagh) How far and in what ways do you agree with this description of the text? Mary Shelley’s Frankenstein is a novel which forces the reader to question whether it is a simple horror story or whether it is a gothic fairytale of many depths. Frankenstein is considered by many critics as the first modern horror story ever written, and it opened a whole new world of ideas for novels and has inspired many similar works since its publication in 1818. As we see by the prelude, Shelley’s first ambition is to horrify the reader as she describes wanting to ‘awaken thrilling horror - one to make the reader dread to look around, to curdle the blood and†¦show more content†¦For many readers, Frankenstein is much more than a simple horror story, it is a story about family, abandonment, the consequences of the quest for knowledge, and many other themes which influence the path of the story. One of the most notable themes within the novel is the idea of good versus evil. This theme adds extreme depth to the text, as the reader is left to decide w hich character is good and which is evil. Shelley’s use of intertextuality in the novel emphasises her point, especially with the inclusion of the strong influence that Milton’s Paradise Lost has on the monster. I am thy creature: I ought to be thy Adam, but I am rather the fallen angel, whom thou drivest from joy for no misdeed. From the moment he is created, we, like the monster question whether he is Adam, or the fallen angel, and therefore wonder whether it is he or Victor which is the creature of evil. The tale of Frankenstein leads the reader into the logic of creation and of the mind, and through her thoughts on good versus evil; Shelley also forces the reader to look even further beyond the horror of the novel to the idea of the doppelganger effect. In the National Theatre’s production of the novel, the two main characters switched the roles of Victor and the monster, emphasizing the point that both characters could be in fact

Macbeth- the Destruction of Power Free Essays

Within William Shakespeare’s play, ‘Macbeth’, the destructive nature of power is immensely explored. The nature of power is obliquely and inevitably expressed through Macbeth’s ambitious drive for supremacy, the unknown and distraught notion of fate and free will, as well as a personal reaction towards the concept of power. Although, the majority of the play is based on the destructive nature of power, the moral nature of power is also portrayed, in spite of the evil. We will write a custom essay sample on Macbeth- the Destruction of Power or any similar topic only for you Order Now Macbeth was naturally an ambitious man, who constantly desired more. However, he was greatly influenced by his wife Lady Macbeth, for in the beginning Macbeth’s nature was â€Å"too full o[f] the milk of human kindness†. Lady Macbeth’s provocation encouraged the evil residing in Macbeth and his ambition only increased â€Å"I have no spur to prick the sides of my intent, but only vaulting ambition, which o’erleaps itself and falls on the other. † The weird sisters were aware of his overpowering determination and were able to manipulate him into believing he had the potential to gain â€Å"absolute power†. Via these strong influences and his unfathomable ambition, Macbeth went to great extents to retrieve ultimate power, essentially transforming into a tyrant within the process. Macbeth’s level of free will is questionable, for it seems that despite the triggers of his ferocious actions, he was an exceptionally hubris man. The witches can be depicted as advocators for fate, rather than fate itself and with the support of manipulation, they were able to convert Macbeth into an ignorant autocrat. â€Å"Fair is foul and foul is Fair. Weird sister’s prophecies were not what they seemed. Although, Macbeth received various triggers that led to his destiny, it is likely that he would have received the same fate, had the witches not interfered. â€Å"I’ll make assurance double sure, And take a bond of fate. † Macbeth attempts to control fate by murdering his possible threats to power. Macbeth was ambitious at heart and clearly a power driven man, whom takes pride i n his masculinity and in essence already on the pathway to destruction. Macbeth was too focused on gaining his own power and control, to comprehend the issues arising against him. As Macbeth aspired to optimum power, he gradually began to dehumanise. â€Å"What need we fear who knows it, when none can call our power to account? † Lady Macbeth questions whether the guilt and anxiety of murdering these loyal people was worth the power or lack of it. The weird sisters manipulated Macbeth into believing he was invincible, resulting in irrational acts of terrorism against the people of Scotland. Murder, betrayal, torture and cruelty were inflicted upon all of Macbeth’s followers on a regular basis, whom were forced to obey him. â€Å"I am in blood, stepped in so far, that, should I wade no more† Macbeth went too far, to withdraw and developed into a tyrannical leader for the simple reason he had the power to do so. What he chose to do with his power lead to his corruption, although, not all choose the wrong path. There are some individuals born to lead and gain power, with the intention of goodness and then there are others who do not retain the ability to effectively control their power. Duncan and Malcolm both emanate morality, with the aspiration to improve and support their country, Scotland. â€Å"But I must also feel it as a man,† Malcolm exclaims as he understands he must feel compassion In order to become a respectable leader. The destructive nature of power is explored in many aspects throughout the play, for each individual reacts differently. Macbeth was ambitious at heart and easily influenced to commit such brutality against his own people. However, Malcolm and Duncan were able to harness and control their power with intention of supporting their country to the best of their abilities. Macbeth’s fate seemed inevitable despite the weird sister’s interference, for he already retained the qualities of an ambitious tyrant. Macbeth ultimately desired power with fierce determination and eventually received it. Once he had acquired all power, he became ignorant and apparently ‘invincible’ ultimately resulting in his destruction. How to cite Macbeth- the Destruction of Power, Papers
