bio kerosene

langat kipkorir  [2007-02-20  07:31]   #1818 in a world of such ambiguity, does it mean producing kerosene from biological oil be a backdate of technology. whereby instead of pursuing discovery other sustainable sources, we seek to identify ourselves with past technological systems. does any one of you have information that can assist me in getting detailed information if biokerosene. Johan Erlandsson  [2007-02-20  17:26]   #1819 Langat, welcome to Ecoprofile! First, may I ask what you use kerosene for in Kenya? Johan Erlandsson  [2007-02-21  17:57]   #1824 Right, then I think I understand your question. Am I right if I say that you think it would be better to replace kerosene lighting and cooking appliances with something totally new instead of just switching to bio kerosene, to come away from indoor air pollution? I believe the same reasoning also goes for cars. Why do we stick to the ancient and ineffiecient internal combustion engine when we instead can replace it with high efficiency electric propulsion? With all development of processes to produce biofuels, this seem to be the case. What do you want to know about bio kerosene? Johan Erlandsson  [2007-02-26  08:12]   #1830 Given the rapid development of solar power, batteries and very energy efficient LED lighting, I would guess that at least kerosene for lighting can be cost-efficiently discontinued in the nearest ten year period. I am afraid I do not have information on how to produce bio kerosene and what emissions is emitted during combustion at this time. Do you think emissions differ a lot? Is it OK if I ask some general questions about energy use in Kenya? If so, to what degree are refrigerators used? I guess that with no electricity, there are neither refrigerators in Kenyan homes? langat kipkorir  [2007-02-26  13:21]   #1832 Electricity usage is about 80% for the urban settings and about 45% for the rural households. Refigeration technology is widely being used given that kenya lies within the temprate countries with very high tempratures during the day Johan Erlandsson  [2007-02-26  20:08]   #1833 I searched a little bit on Google for biokerosene, but could not find much on emissions. Everything is about aviation fuels. I guess that those without electricity do not have access to refrigerators? How do they manage their food? Sorry about my off-topic questions, but I have hoped to manage energy supply in my small cottage from solar and wind power. However, I have realised that just refrigeration is a little bit too energy consuming for this. So I am interested in how these people manage without refrigeration. langat kipkorir  [2007-03-03  14:38]   #1836 a simple design ussually used for preservation especially in zones with no electricity is the charcoal fridge technology. drying, salting, smoking are other non conventional methods of preservation mostly used. Johan Erlandsson  [2007-03-06  22:20]   #1840 I googled for "charcoal fridge" and found this picture. I do not really understand how water dripping on charcoal can produce a cooling effect, but it is renewable! :-) I have to try this at home. Langat, what is your opinion on solar power? Could it be used in Kenya to supply homes with electricity?  http://www.newvision.co.ug/D/9/31/421901
