Survey of #Sustainable Development to Make Great Man-Made River Producing #Energy and #Food #Agriculture #Hydrokinetic #PowerGeneration #SolarPowered desalination plants

Author: Mohamed Nasar Nasar

The Great Man-Made River (GMR) is the world largest irrigation project, consisting of a network of pipes that supplies water from Libyan desert in the south to the coastal areas in the north. This paper studies the possibility of taking advantage of GMR to generate energy and produce food through agriculture. Hydro-kinetic power generation, would be carried out by generating energy from water movements across Great Man-Made River pipelines using appropriate sizes of turbines. It’s known that the length of the GMR pipeline is about 4000 km with a diameter of 4 m. Pipeline of such magnitude with great water flow rate would make a turbine to produce hundreds of Kilowatts of clean energy. The most significant reasons that force us to take advantage of GMR to generate energy are: a) The needs to sustainable environmental energy source; b) Power System uses energy of flowing water to provide a consistent, controllable, non-weather-dependent source of electricity, such as other types of renewable energy, which are depend on the weather. The conversion of GMR, from supplying freshwater to coastal cities, to huge agricultural project after the establishment of many seawater desalination plants (solar powered) would cover the needs of cities for fresh water. Thus it would become possible to convert thousands of desert hectares around the pipelines to huge agricultural project irrigated from GMR.

The secrets of blue-green algae’s rapid growth characteristics are coming to light. Synechococcus 7002 flourishes under intense light, tripling in size to accommodate a rapid expansion of the cellular machinery it uses to build proteins. Most cyanobacteria slow their growth in these conditions and redirect resources to repair damaged cells. But this blue-green algae does chemistry on the fly and grows more rapidly. This is why it is attractive to researchers who want to create better, less expensive biofuels and sustainable bioproducts. Read more at http://goo.gl/wzQVzF.

8-9k for a leaf and saving the planet
 
Buying a used Leaf for 9K and powering it with solar energy from your solar panels to replace a car refilled weekly with 18 gallons of gasoline is the same as planting 382 trees. Below is the math. Charging a used Leaf at home draws just 3.3 kw compared to 4.4 kw for a clothes dryer.

Burning 1 gallon of gasoline creates 19.6 pounds of CO2, since gasoline is mostly carbon by weight and molecular mass of CO2 is 44 (compared to 12 for carbon). Gasoline is 3.84 liters (87% is carbon), density is 1.7 pounds/liter, so CO2 mass is about 3.84*0.87*1.6*44/12= 19.6 pounds.

If you drive an electric car powered by the sun, you avoid releasing 18345 pounds of CO2 into the air, if you fill up once a week an 18 gallon fuel tank, 18*52weeks*19.6=18345. 18 tons of CO2 or almost 9 metric tonnes of CO2.

Each tree absorbs 48 pounds of CO2 a year, when mature, so 18345/48=382 trees equivalent.

Hybrid industries DOUBLES THE RANGE OF THE LEAF for only 6.5K, and a used Leaf in California can be gotten for 8.5k only ►► ►http://hybridindustries.webs.com

The Leaf is the best selling electric car globally, having sold 200,000+ already. Used ones go for 8-9k now even. You will pay 3 times less on fuel, since electricity is 3 times cheaper (it can be 5-7 times cheaper in some countries though). Or pay zero if you don't mind driving to a public free charging station and wait 30 minutes for a quick charge of 80 miles. Nissan replaces your battery for free if your battery has 9 bars instead of the 12 on a new car. 100000 mile warranty goes to your used car when you buy it and you get to use the CAR POOL LANE too when alone, as most Leafs have the sticker on them. Los Angeles Department of Water and Power and other places like Nissan, Toyota, BMW, etc have free quick charge stations too. Can do some email, texting and get free charging. if your workplace offers free electric car charging (many companies do), you no longer have any fuel expense and no trip to quick charge stations or home charging, plus no oil change either, far less maintenance. Just google the nearest free public charging stations. The Android App is PlugShare, 90000 charging stations on this network.

Most people charge in the garage while sleeping between 11 pm to 7 am. http://www.mynissanleaf.com/viewtopic.php?t=13008#p295725 explains how to get 23 miles per hour charging at home on a 240 dryer plug with 30 amp circuit. for example. You can upgrade the cable the leaf comes with as the link explains for faster at home charging.

If your very old gas car or hybrid is worn out and the time is to buy a newer car - there are many used Leafs and the range is about 80-90 miles depending on how much it was driven. If you want longer range, you can pay 22k (after rebates) and get a new 2016 leaf that comes with 110 miles. Only the upper models of 2016 leaf offer the extra range. Only Nissan offers an affordable car with such a big range now. All the other electric cars offer only about 60-90 miles range.


Below are some reasons for buying your next car electric, installing solar panels and supporting 100% renewable energy in all nations (via carbon price for example):

1. help humanity survive since absorbed CO2 leads to ocean acidification which kills plankton. Plankton generates 50-80% of oxygen we breathe, so without oxygen we will diehttps://plus.google.com/+AlexP/posts/hRv2Z4DmTUX

2. help humanity since elevated CO2 levels were shown to impair brain performance of all future humanshttps://plus.google.com/+AlexP/posts/SskhmQCkqQz. Today in offices with high CO2 levels (like we will have if no action is taken), people's brain performance decreases.

3. Help humanity as you no longer generate carcinogenic exhaust, otherwise known as smog, which kills millions of people each yearhttp://goo.gl/jDj0hI and leads to lower IQhttp://goo.gl/alNQIk and autism ► http://goo.gl/66nqwr, as well as Alzheimer, cancer, heart disease, asthma, Parkinson, Multiple Sclerosis, Memory Loss, Cognitive Decline as explained in the many studies athttps://plus.google.com/+AlexP/posts/iHVLnhG5vEs. Also, http://www.news.cornell.edu/stories/2007/08/pollution-causes-40-percent-deaths-worldwide-study-finds explains that 40% of deaths are due to pollution. Smog kills billions earlier than their normal time. Coal fired plants generate most human emissions of mercury and arsenic in the air.

4. save lives since you reduce heart attacks caused by traffic noisehttp://goo.gl/Fuhvn. Electric cars are much quieter.

5. save humanity from oil wars that destroy the environment and kill countless civilians. Iraq war trillions could have powered all US with solar/wind ► http://goo.gl/ZqN47.

6. you no longer have to change oil (because there is no oil to change) or spark plugs; no more smog check either; electric cars have 60% less parts, so you will go for repairs much less. Combustion engines are noisy and only 15% efficient; electric motors are 90% efficient.

7. reduce heat and AC costs, because electric cars produce 5 times less heat than combustion engine cars per mile, reducing the heat-island effect in citieshttp://www.nature.com/srep/2015/150319/srep09213/full/srep09213.html

8. bring the end of gas stations that poison the water wells with MTBE or other compounds leading to billions of dollars wasted in cleaning up the well water (example: $0.4 billion settlement ► http://goo.gl/eKasZD)

9. save money as you spend 4-8 times less money on "fuel" depending what area of the globe at the current low prices of oil. ► https://plus.google.com/+AlexP/posts/aqpoUTuBV5z. If you have enough solar panels, you get free CLEAN fuel for life, since you charge at home and utilities pay you for energy you put on the grid. ► https://plus.google.com/+AlexP/posts/D3B8qikwNie. Likewise, Tesla Motors offers free solar ☼ charging for lifehttps://www.youtube.com/watch?v=wgk5-eB9oTY?

10. save money for noble purposes because electric cars are cheaper than many oil cars after the federal and state rebates: in Colorado, you can buy a Nissan Leaf for only 15, 000, while in most other states for 18-21, 000. A Smart EV costs only $12,000 in Colorado, see http://smartusa.com. Mitsubishi i-MieV is only $13,000 in California and $10, 000 in Colorado ► http://www.evworld.com/news.cfm?rssid=31881.

11. Save money since it is cheaper to buy solar panels over 5-12 years than to pay the electric bill without panels - so you save MONEY and the environment - just choose the best deal, they got 12 year loans for 2-3% interest rate - plus after 12 years you get free electricity for the next 30 years or longer if panels last 60 years which they should.

12. Electric car batteries and solar panels are far greener than alternatives. Battery recycling for today's oil car lead batteries is happening at a 97% rate globally. It will be even better for the far safer lithium car batteries. Lithium Ion batteries are classified by the federal government as non-hazardous waste. Lithium ion batteries are made from nontoxic lithium carbonate (used in ovenware), nontoxic cobalt oxide (in pottery glaze), nontoxic graphite (in pencils), and a polymer (plastic) membrane. The most toxic components are the electrolyte and lithium cobalt oxide, neither of which are persistent in the environment and both of which are increasingly being replaced by safer compounds. Wang Chuan-Fu, CEO of BYD, demonstrated the safety of the electrolyte in their lithium ion batteries by drinking it. Zero Motorcycles founder Neal Saiki said that the Lithium Ion batteries they use are safe to eat.

Solar is way better than coal, oil or natural gas which spew 100-1000 times more carcinogens in the environment per unit of energy produced, besides far more CO2. How long does a solar panel system have to operate to recover the energy used for making the panel? Energy payback for rooftop panels is 1-4 years depending on type. Assuming a life of 30-60 years for a panel, that means that most energy produced will be free from pollution of any sort ► http://www.nrel.gov/docs/fy04osti/35489.pdf.

13. save time, thus money, since you are allowed to use the carpool lanes to avoid traffic if you drive an electric car, in many countries, even if there is only 1 person in the car. 

14. Natural gas and Coal can be replaced with solar-wind immediately:) as a public health priority, especially since they are cheaper in many areas than fossil fuels and storage eliminates the need for sun-wind 24-7 ► http://www.youtube.com/watch?v=PjNKz8qXRmk. In China's worst areas, smog makes people live only 4 decades ► http://www.youtube.com/watch?v=-1DNjJd2YfA. Coal-fired plants lead to birth defects in China, see the 2 min video ► http://www.youtube.com/watch?v=1wImJC6xEoU. In all nations, including USA, people near coal-fired plants often die of cancer at 45 or so, see the 10 min video ► http://www.youtube.com/watch?v=KZWAQ_3yoj8. Coal pollution leads to cancer, asthma, autism (mercury), etc. Clean coal doesn't exist ► http://www.youtube.com/watch?v=_l0iqdfFyC0.

15. Germany increased its solar capacity 16000 times between 1990 and 2012https://plus.google.com/110265788529286523789/posts/2K5Ln8zyrqH. It's possible. In 2014, Denmark generated 39% electricity from wind ► https://plus.google.com/110265788529286523789/posts/1FraSFPpWBv. For comparison, the current renewables percentage in the US India & China 15%, Japan 11%, Israel 2.6%, Russia 15% (hydro), Mexico 26%, UK 25%, Canada 60% (hydro), Portugal 50% (hydro+wind), Brazil 90% (hydro), Iceland 100% (hydro+geothermal), Ghana 75% (hydro), Spain 45% (wind-solar-hydro), New Zealand 80% (hydro+geoth+wind), Paraguay & Norway & Lesotho & Bhutan 100% (hydro), All Africa 32% (hydro), Germany 33%, Italy 29% (solar-wind-hydro), Sweden 52%, Finland 37%.

I seem to be nearly alone in this but I still don't understand what this around the world flight in a solar powered man carrying aircraft was supposed to be demonstrating. That a solar powered aircraft could be made, and that it could fly around the world if someone wanted to do it, was not in doubt. NASA and others have built extremely high flying drones that can stay aloft for extended periods on solar power. That this can be done in a practical human carrying aircraft was not demonstrated here. This aircraft was extremely fragile (it will break apart in any serious turbulence), extremely slow, (one could have rowed around the world in the time it took for this to fly, and any headwind woul dhave it flying backwards), it has an extremely low climb rate (which means it can't outclimb a downdraft), it is highly dependent of weather conditions, cloud cover, and it has a payload of less than 4% of gross weight (compared to many fossil fuel aircraft that can often carry a useful load of over 50% of gross weight).

This was a publicity stunt, which is fine, but it seems like the publicity was primarily for the pilots and not to promote solar power (since the solar plane project doesn't actually make sense). Look, I know I am being the cranky old guy here but this isn't about preferring fossil fuels to solar, I am a huge fan of both solar power and aviation and I love innovation, but there are actual physical constraints to be considered here and this project doesn't address those. An aircraft inherently needs a certain power to weight ratio in order to have sufficient power to takeoff in a reasonable distance, climb against downdrafts and over mountains and weather, move at a speed significantly faster than winds (which can be over 150 knots at altitude, and half that only a few thousand feet above ground). Solar power, never more than 1KW/sqM (with a 100% efficient solar cell, at noon, at the equator, with no cloud cover) is just not enough to power a practical aircraft.

You can easily build an aircraft that indirectly runs on solar power, charging batteries or synthesizing fuel, but not directly.

#Minnesota Power Seeks Proposals #RFP for Large Scale #WindEnergy #SolarEnergy and Customer Driven Resources #USA

Minnesota Power today is releasing the first in a series of Requests for Proposals as part of the company’s broad resource evaluation process to further its EnergyForward strategy. EnergyForward calls for a diversified power supply to meet customers’ needs reliably and cost effectively in an environmentally responsible manner. Minnesota Power will consider the costs and characteristics of the proposals received and analyze whether they are beneficial resource additions for its customers.

In approving Minnesota Power’s integrated resource plan in June, the Minnesota Public Utilities Commission asked the company to consider additional wind, solar and demand-side management alternatives as part of its ongoing resource evaluation process.

In the initial Request for Proposal, Minnesota Power, a division of ALLETE Inc. (NYSE:ALE), is seeking power supply proposals for up to 300 megawatts of wind generation beyond the 625 megawatts of wind it has on its system. The company seeks to purchase low-cost renewable energy that fully maximizes the benefits of the extended Federal Production Tax Credit (PTC) for wind projects on behalf of its customers.
