Biomass Energy in Africa. In my previous blogs, I talked much about the benefits of renewable energy and its different forms, namely: geothermal, wind, community energy, and waste-to-energy.
In this article I will introduce yet another source of renewable energy that has been showing a lot of promise for African countries: biomass. Biomass is organic matter, or matter that comes from a living or recently living organism, that can be transformed to energy through either thermal, chemical or biochemical processes. Perhaps the biggest benefit of biomass is that is considered as sustainable, clean and ‘green’ energy (i.e. it doesn’t emit too much carbon and doesn’t contribute to global warming).

Cane is used for biomass energy. A cogeneration plant in Metz, France. The station uses waste wood biomass as an energy source, and provides electricity and heat for 30,000 dwellings. Biomass is biological material derived from living, or recently living organisms. It most often refers to plants or plant-based materials which are specifically called lignocellulosic biomass. As an energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel. Wood remains the largest biomass energy source to date; examples include forest residues (such as dead trees, branches and tree stumps), yard clippings, wood chips and even municipal solid waste.

Forget the fuel. Charge your gadgets. Support a better world. The heat from the fire generates electricity via a thermoelectric generator to power a fan creating airflow for improved combustion. See the CampStove in action with our interactive map. Top Using BioLite's patent-pending thermoelectric technology, BioLite Stoves convert heat to electricity that powers a fan to make the fire ultra-efficient. Extra electricity can be used to charge small electronics like mobile phones and LED lights.
Mystery Ingredient Cleaning Earth's Atmosphere. June 4, 2009 Mother Nature has a previously unknown cleaning agent that scrubs away toxic air pollution, scientists have discovered.
What's more, the existence of the still mysterious substance has shaken up decades-long assumptions about our atmosphere's self-cleaning process. Many studies have shown that trace gases and pollutants in the lowest level of our atmosphere break down naturally, thanks to molecules called hydroxyl (OH) radicals. But the breakdown spews out ozone, itself a toxic pollutant and a greenhouse gas. (Get global warming facts.) Not so in China's heavily polluted Pearl River Delta, where experts were stumped to find lots of OH radicals but relatively small amounts of resulting ozone. Piña Colada Cupcakes. Pineapple and coconut top these light pineapple cupcakes, what a perfect Spring dessert!
For the coconut lover out there, these are super easy, low fat, moist and delicious! A variation of my pineapple bliss cupcakes, using a box of yellow cake mix and a can of crushed pineapple; no eggs, no oil or butter needed!! This is great for lazy bakers like me, takes less than 10 minutes to prep! You can make the cupcakes a day ahead and the topping as well which should be stored in the refrigerator. Once you top them with the frosting they should be eaten within a few hours.

IEA BioEnergy Agreement Task 33: Thermal Gasification of Biomass (home) Gasification. Gasification is a process that converts organic or fossil based carbonaceous materials into carbon monoxide, hydrogen and carbon dioxide.
This is achieved by reacting the material at high temperatures (>700 °C), without combustion, with a controlled amount of oxygen and/or steam. The resulting gas mixture is called syngas (from synthesis gas or synthetic gas) or producer gas and is itself a fuel. The power derived from gasification and combustion of the resultant gas is considered to be a source of renewable energy if the gasified compounds were obtained from biomass. The advantage of gasification is that using the syngas is potentially more efficient than direct combustion of the original fuel because it can be combusted at higher temperatures or even in fuel cells, so that the thermodynamic upper limit to the efficiency defined by Carnot's rule is higher or not applicable. History  In a gasifier, the carbonaceous material undergoes several different processes:
