Energy
To make the bio-diesel from Calotropis Procera. I have searched a lot on internet and journals on this plant. I want to know that this plant is better than the Jatropha for this purpose. I wnat your help on this because I have a very few days left and I have to submit the plan. The first question possibly will be "Prove that Calotropis is better option then Jatropha. Question by Nitin Lahoti
My answer to the question to prove that Calotropis is better option is as below.
There are 5 main considerations in terms of a. Biomass production b. land availability,
c. cropping requirements d. harvesting techniques e. regeneration potential.
Calotropis beats Jatropha on all the five points
The US average wind speed is 12.5 mph.
If you double the wind speed you increase power potential by times 8.
If you double the diameter of your blades increase power potential by times 4.
Last check on current average market prices I'd put solar at $10 (USD) per watt, wind at $1 per watt (if you buy rather than build, this is about why you should build).
Those are some of the standard basics of wind electric generation.
If I felt photovoltaic (aside from just assembly) was something I could build at home I'd likely write about that.Some background to the author of this blog:
A new study in BioScience suggests that boosting use of maize-derived ethanol will increase greenhouse gas emissions and worsen the effects of climate change as a result.
The research focuses on how mandated increases in production of the biofuel in the United States will trigger land-use changes domestically and elsewhere. In response to the increased demand for maize, farmers convert additional land to crops, and this conversion can boost carbon dioxide emissions.
Researchers from Kuwait University predict that world conventional crude oil production will peak in 2014 — almost a decade earlier than some other predictions.
The team explains that scientists have developed several models to forecast the point at which oil production reaches a maximum and then declines, and some put the date at 2020 or later. One of the most famous forecast models, called the Hubbert model, accurately predicted that oil production would peak in the United States in 1970.
There are 5 specific groups working on biofuel and all with different meanings and purposes and ends.
First group is people like me who started working on biofuel when Professor Melvin Calvin found out that during second world war plants were used to obtain biofuel and he started the work at UC Davis California almost in 1973 or so follow by others However once the prices and crisis came down people forgot this work or tried to put is aside.
Tel Aviv University biologists say a solution to our search for alternative energy may come from an unexpected source ― peas.
Researchers isolating minute crystals of the PSI super complex from the pea plant suggests these crystals can be illuminated and used as small battery chargers or form the core of more efficient man-made solar cells.
To generate useful energy, plants have evolved very sophisticated "nano-machinery" which operates with light as its energy source and gives a perfect quantum yield of 100%. Called the Photosystem I (PSI) complex, this complex was isolated from pea leaves and crystallized, which enabled researchers to describe in detail its intricate structure.
Biomass currently supplies about a third of the developing countries’ energy varying from about 90% in countries like Uganda, Rawanda and Tanzania, to 45 percent in India, 30 percent in China and Brazil and 10-15 percent in Mexico and South Africa. The crucial questions are whether the two billion or more people who are now dependent on biomass for energy will increase. The fact that 90 percent of the worlds population will reside in developing countries by about 2050 probably implies that biomass energy will e with us forever.
Plants and algae, as well as cyanobacteria, use photosynthesis to produce oxygen and "fuels," the latter being oxidizable substances like carbohydrates and hydrogen. There are two pigment-protein complexes that orchestrate the primary reactions of light in oxygenic photosynthesis: photosystem I (PSI) and photosystem II (PSII). Researchers writing in PNAS say they have taken a significant step closer to understanding how these photosystems work their magic, which may boost the effort to develope new sources of energy.
Researchers have developed a way to produce ethanol from waste products such as orange peels and newspapers. The approach is 'greener' and less expensive than the current methods available to run vehicles on clean energy and can be applied to several non-food products throughout the United States, including sugarcane, switchgrass and straw.
The new technique uses plant-derived enzyme cocktails to break down orange peels and other waste materials into sugar, which is then fermented into ethanol. The findings are detailed in Plant Biotechnology.
