Biofuels have been around as long as cars have.

A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms.

Generating Electricity from Wing Waves.

Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.

Producing electricity from solar energy.

Solar energy is a free, inexhaustible resource, yet harnessing it is a relatively new idea. The ability to use solar power for heat was the first discovery.

Turbines catch the wind's energy with their propeller-like blades.

A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade.

Solar energy may have had great potential

Solar technology advanced to roughly its present design in 1908 when William J. Bailey of the Carnegie Steel Company invented a collector with an insulated box and copper coils.

We have been harnessing the wind's energy for hundreds of years.

For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant.

Biofuels are produced from living organisms.

In order to be considered a biofuel the fuel must contain over 80 percent renewable materials.

Geothermal energy is the heat from the Earth.

Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Geothermal heat pumps can tap into this resource to heat and cool buildings.

A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building.

In the future, civilization will be forced to research and develop alternative energy sources.

Possession of surplus energy is, of course, a requisite for any kind of civilization, for if man possesses merely the energy of his own muscles, he must expend all his strength - mental and physical - to obtain the bare necessities of life.

Hydrogen Hawaii Malala Elephants And Tuna

Hydrogen Hawaii Malala Elephants And Tuna
In case anyone was wondering what happened to my renewable energy review series, it will continue next week. Today, I will provide insights into recent news, starting with the future of aviation, Hawaii's greatest need:

1. A 20-ton lifting capacity Aeroscraft rigid airship was tested, with funds primarily from the Department of Defense. The ultimate 500-ton ship lifted by helium should fly at speeds up to 140 MPH. My" HUFFINGTON POST "article on The Future of Sustainable Aviation touched on this form of transport. Unfortunately, the fuel for this craft will continue to be fossil liquids.

"However, there is also Rinaldo Brutoco's (right") H2 Clipper ("I like to think the H2 also stands for Hawaii Hydrogen, as shown below"), capable someday for bringing tourists to Hawaii from the West Coast. Here are some details. Peter Hoffmann of the Hydrogen and Fuel Cell Letter reported on the H2 Clipper in October of this year. Because this craft will fly up to 350 MPH, the flight would only take eight hours. You say, isn't hydrogen dangerous? Well, there was the Hindenburg. On the other hand, recent studies have shown that, not hydrogen, but certain design features which can be overcome, were responsible. Further, this gas would power the fast dirigible and also transport hydrogen produced by our geothermal energy fields, wind energy farms and ocean thermal energy conversion plantships to the mainland. Thus, someday we might become an energy exporting state.

"As Hawaii is so dependent on tourism, we absolutely need to find a replacement for the jetliner because when oil prices shoot past 150/barrel someday, we will be screwed, and enter into a prolonged economic depression. Brutoco's concept (left") is our best hope for long-term progress. Now that Senator Dan Inouye is no longer around, though, I fear Hawaii becoming a bit player in this development, at best.

"2. The HONOLULU STAR ADVERTISER" featured headline on the front page today said:

SENATORS PLACED ON KEY COMMITTEES


I got news for you. No one is on the Appropriations Committee in either house. That's terrible. Energy, Commerce, Armed Services, Foreign Affairs and Indian Affairs are all authorization committees. They are close to useless. You need to be on the Appropriations Committee to insure that your chairman inserts your pork into the final report. Not only has Hawaii lost seniority, we are on the wrong committees. The most disappointing of all is Brian Schatz, our senior senator, not replacing Senator Dan Inouye on that committee. In a word, Hawaii could well be double-screwed.

3. Malala Yousufzai was released from Queen Elizabeth Hospital in Birmingham, England. She miraculously survived that assassination attempt by the Pakistan Taliban, and at the age of 15, could well gain the Novel Prize later this year. She needs to return for, get this, cranial reconstruction, so all is not yet well. While she was in the hospital, the only request she had of her father was to bring to the hospital her textbooks. The Pakistanian government gave him a job as an attach'e in their United Kingdom embassy, so she should be safer there than at home.

4. Was this a landslide? The final Electoral College tally showed an Obama victory over Romney of 332-206. I suspect our tax money is being used to pay for this useless formality, and should be discarded. I'll have a posting soon on a proposed National Constitutional Convention, so we can fashion a mid-course correction for our government. Items like the second amendment and term limits on Congress should also be re-addressed. A lot has changed in more than two centuries. Oh, by the way, the 2008 Obama's campaign just got fined 375,000 by the Federal Election Commission for irregularities. Why did it take so long> Recall? I wonder how much the hit will be in 2012? That's our President in home state Hawaii this week with his obligatory Hawaii shave ice.

"5. Remember my October posting on Ivory Hunters? Hong Kong just seized 2,900 pounds of ivory, said to come from 800 dead elephants. 40 tons were re-captured in 2011 alone, representing 22,000 dead elephants. Just think about those tusks that passed through the system, and the elephants that had to be massacred. And, no, these assassins cannot tranquilize and just cut off the tusks like Florida stone crabs (where the claws are taken off and the crustacean tossed back into sea because there is limb regrowth"), for they are needed for survival. There are now around half a million elephants in Africa and a tenth that in Asia.

6. Kiyoshi Kimura ("in photo with the whole fish") paid 1.76 million for a 489 pound blue fin tuna. That's 3600/pound. I thought I was extravagant when I bought a pound of chu-toro ("same fish, which, arghh, is a threatened species") for all of 32, less than one-hundredth that of Kimura's. Here are a couple more shots of this vulgarism:

It takes an ounce of flesh to make one sushi. Thus, just these two must be sold for more than 450 for him to make a profit. My whole Jiro lunch "only" cost 350...for twenty sushi and sake, with half a musk melon at the end.-
