Alternative Energy
 
Energy has become integral parts of our day-to-day lives. Energy is required to produce electricity for domestic and industrial applications. We need energy to drive our vehicles, to run the machines, keep our houses cool and hot, run the computers and mobiles, and for a number of other purposes.
Comparison of Traditional and Alternative Energy Sources:
Traditionally we have been using fossil fuels for production of electric power and driving our vehicles. The fuels used for the generation of electric power are fossil fuels like coal and oil, and nuclear fuels like uranium. The fuels used commonly for running the vehicles are crude oils like gasoline and diesel. Alternative energy refers to the energy that is not dependent on fossil fuels, crude oil and nuclear fuels. Alternative energy, also called as renewable energy, is obtained from various sources like radiations of the sun (solar energy), wind, water, geothermal heat and tides in the oceans. Burning of fossil fuels is one of the major causes of environmental pollution and greenhouse effect. They release lots of carbon dioxide and particulate matter. The alternative or renewable energy is considered to be the clean energy since extracting energy from its sources does not produce any pollution.
The sources of energy like fossil fuels, crude oil and nuclear fuels are also called as non-renewable sources of energy since their deposits are reducing in the nature as they are being used extensively throughout the world. Fuels like coal, natural gas and oil took millions of years to develop but once used they cannot be replaced immediately. The alternative energy on the other hand is available in abundance from various sources and they get replaced easily immediately or within short period of time.
Alternative sources of energy provide unending supply of energy. For instance the solar energy from the sun will be available for unlimited period of time till the sun keeps shining. Solar energy can be collected by the collectors and it can be used for a number of applications like cooking food, heating water, generating electricity, running the vehicles etc. Similarly, the wind will keep on blowing on the surface of the earth tills its atmosphere is in place so it can be utilized for unlimited period of time. The ability of the wind to produce motion can be utilized to run the fans of the windmill and produce electricity from them.
The tidal energy is obtained from waves of the oceans having huge quantity of water that would last forever. One of the important sources of alternative energy is hydro-power used for the generation of electricity in hydroelectric power plants. Throughout the world, the hydroelectric power plants are one of the major sources for the generation of electricity. In these plants the flow of river is blocked at certain places and water is allowed to be collected at large height in the dam. The rivers have been flowing since thousands of years and continue to exist for unlimited period of time as they are replenished by rain water from time-to-time.
Geothermal energy is obtained from the lower layers of the earth usually for producing the heating effect. Once the energy is obtained from the earth, it is replaced immediately naturally and it can be used for ending period of time interval.
Another important source of alternative energy is the biomass like waste wood, leaves of the plants, broken branches and twigs of the trees, agricultural wastes, garbage, human wastes etc. The fuels obtained from biomass are called bio-fuels. Some of the common bio-fuels are ethanol, biodiesel, and natural gas. Biodiesel is a type of alternative fuel used for running of the vehicles. It is made from renewable energy sources like plant and animal fats. Biodiesel is not a petroleum fuel, but it can be easily blended with petroleum fuel diesel in various proportions.
All the above alternative sources of energy are expected to last for long intervals of time line. While the supply of coal, oil and natural gas is expected to reduce and stop in the future, the supply of energy from sources like sun, wind, water, earth, and biomass is expected to last forever.
Consumption of alternative energy in US has been increasing over the years. In the year 2009 the consumption of alternative energy in US was 7.7 quadrillion Btu, which was 8% of all the energy used in the whole nation. Half of the alternative energy was used for producing electricity, while 10% of the total electricity produced was from alternative energy sources. Besides this alternative energy sources were also used for production of heat and steam. Alternative energy was also used for transportation, and to provide heat for homes and businesses.
Alternative energy sources reduce the pressure on fossil fuels and also help keep environment clean. The only major problem is that alternative energy is expensive compared to the fossil fuels mainly because they are located in remote places and its difficult to bring them to the main grid. Some of the sources like wind and solar are not uniform during various periods of the day and the year. However, their demand has been increasing and various technologies are being developed to utilize alternative energy sources more efficiently.

Human growth hormone (HGH) from algae

 

 

Rehovot, Israel-based Rosetta Green Ltd., which specializes in crop improvement for the agriculture and alternative fuel industries using unique genes called microRNAs, has successfully completed an experiment producing human growth hormone (HGH) and validated its biological activity. Proteins produced by both treated and control algae were tested with an in vitro activity test assay by an independent third party using the conventional proliferation method. The activity test assay found that Rosetta Green’s treated algae exhibited hormonal activity.

The project is part of a joint European effort to manufacture chemicals and proteins in algae, which is implemented and funded by the European Union as part of the European Commission’s Seventh Framework Program for Research and Technology Development (FP7). More than ten European organizations are participating in this project, including companies and leading universities, which has an estimated budget of about $7 million US. The project is being managed by Professor Sammy Boussiba of the Microalgal Biotechnology Laboratory of Ben Gurion University of the Negev.
Rosetta Green focuses on using microalgae to develop and produce human proteins for therapeutics, a process that reduces the currently steep drug production costs associated with using mostly mammalian cells and bacteria.

According to Amir Avniel, Rosetta Green’s CEO, “Algae may be an effective source for the production of proteins and vaccines. Rosetta Green has vast experience working with molecular methods in algae. The company worked on the development of designated algae in order to produce the protein in cooperation with the EU. Algae can be used for multiple applications such as producing chemicals, industrial food supplements, bio fuel and food. We believe that the technology that we develop provides significant advantage to improve various traits in plants and algae. We continually seek partners to develop our products and technologies.”

Growth hormone is a peptide hormone secreted by the pituitary gland. Among its functions are the regulation of protein production and the stimulation of bone growth in children. Growth hormone is normally secreted throughout a person’s life, but the amount decreases by 14% every decade after the age of 21. A deficiency in this hormone is known to cause growth block, short stature and dwarfism.

Currently, growth hormone is produced by major multi-nationals such as Pfizer, Lilly, and Merck Serono and used as a prescription medicine to treat children with growth problems and adults with hormone deficiency as well as other symptoms characterized by growth complications. Total annual sales of human growth hormone are estimated at approximately $3 Billion US.

Growth hormone is administered today primarily through daily injections over several years. The accumulated cost can reach hundreds of thousands of dollars per child. Rosetta Green believes that manufacturing the hormone using microalgae will likely reduce today’s high cost of production, which relies upon currently available techniques.

Fuels From Algae

In the spectrum of alternative fuel sources, biofuel made from algae
is perhaps the most easily mocked.
 How could the slimy green muck that
grows in your aquarium and washes up on the beach be a future
cornerstone of American energy independence? So when President Obama
stood before the University of Miami recently and said algae could
provide up to 17 percent of our transportation fuel, we wanted to know:
Is he right? Here’s what we found out:
In February, President Obama announced the Department of Energy would
allocate $14 million in new funding to develop transportation fuels
from algae. DOE is already supporting over 30 such projects, together
worth $94 million.

CCRES ALGAE

CCRES ALGAE

 We are committed to overcoming the world’s impending economic and environmental constraints with technology that produces sustainable, affordable, and local bio-based products from algae.

Algae hold great promise in the near term to fundamentally change America’s energy portfolio, sequester or convert atmospheric CO2 into market-ready products, and help grow our economy through the creation of tens of thousands of well-paying green-collar jobs. Algae-based jobs include:

Based on a survey conducted by the Algal Biomass Organization in January of 2010 with 52 reporting companies, a likely estimation of job growth is shown in the chart below as Scenario 1. In addition, based on the same survey, with the addition of regulatory and legislative parity in the US, accelerated job growth could occur as estimated Scenario 2.

Algae-based products and processes:

  • Can replace a significant percentage of America’s petroleum-based liquid transportation fuel, including jet fuel, gasoline and diesel, using photosynthetic and non-photosynthetic processes;
  • Are domestically produced and renewable;
  • Consume enormous amounts of CO2, and biologically sequester or beneficially reuse/convert atmospheric and industrial CO2into marketable products;
  • Can be grown in non-potable water, on non-agricultural land (thereby avoiding indirect land use issues).
  • Will be commercially produced in the near-term; low-carbon, drop-in transportation fuels will be produced by CCRES members within two years.
  • Can provide value-added co-products, including nutraceuticals, animal feed, cosmetics, plastics and other bio-based products, while also creating renewable, sustainable fuels.

The Life of Algae

This video from Sapphire Energy tracks the cultivation of algae from their San Diego lab in microscopic images, to petri dishes, to flasks, and then outside in their Las Cruces, NM facility and into 14′, 40′, 100′ and half-acre ponds. This is the path that many thousands of strains have taken as Sapphire refines their library of commercial strains that will be used in their Green Crude Farm or Integrated Algal BioRefinery (IABR) now under construction in Columbus, NM. At the Green Crude Farm, the world’s first commercial demonstration scale algae-to-energy facility, algae will be cultivated in ponds over 2 acres in size.

Build an Aquaponics Grow Bed

  • Measure the length and width of the aquarium with the measuring tape.
  • Cut the plywood with the saw to the dimensions of the aquarium you measured in Step 1.
  • Cut four beams the same length and width of the plywood you cut in Step 2.

  • Drill holes into two beams and screw them together at a 90-degree angle. Lay the other two beams across the aquaponics grow bed.

  • Cut legs for the aquaponics grow bed frame. Place the frame where you will use it and measure and cut the legs to the length you need, keeping in mind the need to make them longer if there is a slope.

  • Drill holes into the legs. Keep them flush with the edge of the frame and screw them into place securely. Place the frame onto the plywood you cut in Step 2.

  • Place the grow bed right next to the aquarium or pond. Line the grow bed with pond foil the same length and width of the grow bed. Pour gravel on top of the pond foil in the grow bed. Cut a hole through the center of the grow bed and pond foil with the saw.

  • Place the water pump in the fish tank or pond and connect the water-in pipe to the pump.

  • Pull the water-in pipe through the hole in the grow bed. Install the overflow drain into the grow bed and set it to a few inches above the height of the grow bed to prevent water from overflowing.
  • Fill the aquarium or pond with water and place plants into the gravel of the grow bed.
