“Imagine if you could generate electricity using nuclear power that emitted no radioactivity: it would be the answer to the world's dream of finding a clean, sustainable energy source.” [Quoted from sciencealert.com.au]

Marker at abelard.org

“Sapru estimates that a typical lithium-air battery can offer an output of 1800 watts per kilogram compared to about 120 to 350 watts per kilogram seen in lithium-ion batteries” [Quoted from wired.com]

radiation fears - visiting capitol building more hazardous than camping outside a nuclear plant

"Using United States Federal Aviation Authority actuarial calculation methods, it is shown that over 1 in 70 Japanese workers will be killed by cancer induced by radiation during their company health checks in a nationwide program which subjects them to the equivalent of over 2000 chest x-rays - more than the average dose received by survivors of the Hiroshima and Nagasaki experiments.

“Recently I was asked to take a barium meal esophagram, also known as a "barium swallow" or gastric fluoroscopy. I refused after I enquired about the intensity and dose. After a long delay, and the worrying statement that the radiologist had to consult a book, I was told it would be 15 millisieverts. I was told that many Japanese companies regard gastric fluoroscopy with this, or even higher doses, as a standard early detection test, which is repeated annually or biannually.

“This means that Japanese workers will be exposed to more radiation than the survivors of the Hiroshima and Nagasaki tests, who received an average dose of 200 millisieverts.

“The single fluoroscopy is equivalent to 150 chest x-rays, and 15 times the yearly maximum exposure allowed in the United States. It greatly exceeds the dose received by workers at high level nuclear plants. It is equal to the exposure received by an astronaut in space for one month (recognized hazard). But the energy is delivered to the most vulnerable organs of the body in just a few minutes.” [Quoted from ratical.org]

“Sensing the absurdity of the EPA standards, Dr. Michael Gough and I commissioned radiation experts to measure radiation levels in the U.S. Capitol building and compare them with the proposed Yucca Mountain standards. The Capitol contains a great deal of granite and marble building materials that naturally emit the same type of radiation as spent fuel.

“Our experts discovered that radiation dose rates at the Roger Williams statue, located between the Rotunda and Senate Chamber, are up to 65 times greater than what the EPA plans to allow at Yucca Mountain.

“The radiation-dose rate at the Williams statue also is up to 550 percent higher than the dose rate received at the fenceline of a nuke plant, and about 13,000 times higher than the average annual radiation dose from worldwide nuclear-energy production.” [Quoted from foxnews.com]

35,428,250kw windmills required
or one nuclear reactor

The problems of solar and wind, first the maintainence required:

“Wind and solar installations aren’t made by Ron Popeil. You don’t “set it and forget it”. Other than having proverbial maids go around and wash off those solar installations every three to four days (which are ironically best placed in the desert), the installations must be replaced every 20 years. All in the face of a 60-80 year lifetime for nuclear plants. (The lifetime promise is the same for wind turbines; but, Danish turbines are only lasting for an average of 16 years.)”

Next problem, the level of energy production:

“Mr. Schmidt [Google CEO] proposes a 100 mi x 100 mi = 10,000 square mile area of solar thermal panels will power the entire United States.”

“Mr. Schmidt’s proposed 10,000 square mile solar thermal installation will reliably provide:
“18.4 sq mi / 0.312 capacity factor = 59 sq mi per 1,000 MW.

“Therefore, 10,000 sq mi of solar thermal panels will yield only 169,491 MW of power. [This would be] 5.1% of the energy consumption of the United States. That’s 3,141,011 MW short.” [Quoted from cleanenergyinsight.org]

Can Shmidt count?

yet again, nuclear irrationality slows human progress

“The focus of this shortage is a short-lived radioisotope that most patients have probably never heard of -- technetium-99m, the "m" standing for metastable. With a half-life of only six hours, the isotope allows physicians to examine bones and blood flow, among other things, then quickly disappears from the body, minimizing the dose of radiation received by the patient. Because of its short half-life, the isotope cannot be stockpiled and must be used within a day or two after it is produced.

“Every day of the year, nearly 55,000 Americans and tens of thousands of patients in other countries undergo nuclear medicine tests -- such as checking for the spread of cancer to the bones or monitoring the flow of blood through the heart -- most of them using technetium-99m. The radioisotope is attached to chemicals that allow it to bind to specific sites in the body, where it emits gamma rays that can be used to produce an image of the area.”

Meanwhile, one of the most dangerous forms of power production kills another 60-plus.

“Russian authorities were reportedly warned in 1998 that Siberia's massive Sayano-Shushenskaya hydroelectric power plant had fallen into serious neglect and was unsafe, more than a decade before this week's deadly accident.

“The death toll rose to 66 Saturday as rescuers continued to drain the dam's destroyed turbine room and recovered 19 more bodies amid the twisted metal and concrete wreckage from Monday's unexplained explosion. Nine workers were still missing from the accident, which has highlighted the dangers of Russia's creaking infrastructure.”

hydrogen micro-car planned in uk


1:43 minutes

“ "Many people lost track of the fact that fuel cell cars are electric cars, since fuel cells store and deliver electrical energy, just like batteries - only with significantly more storable energy per unit of weight. Batteries and ultracapacitors on the other hand, offer more power per unit of weight, but less storable energy" said Taras Wankewycz, one of Horizon Fuel Cell Technologies’ founders. "Technologies have evolved, but more importantly, Riversimple brought them together as one system, in a way that greatly exceeds the sum of their individual benefits. This next generation hydrogen-electric car brings electric vehicles into a new stage where range, charge-time and cost are no longer commercial barriers.”

Marker at abelard.org

“The vehicle maximizes energy efficiency by utilizing lightweight composite materials, eliminating heavy mechanical components, and by networking fuel cells with ultracapacitors and 60% regenerative braking energy into one symbiotic system. The result is ground-breaking: 240 miles (390 km) can be traveled on one small tank of hydrogen weighing only 2.2 lbs (1 kilogram).”

channelling wind to windmills

“Leviathan Energy offers a technology for new and existing wind farms to produce more energy from a relatively small investment.

“Leviathan Energy, using aerodynamics modeling, has developed a unique passive structure that can be adapted to any wind turbine from any manufacturer.

“Leviathan's technology significantly increases the power output of existing wind turbines by cleverly directing the surrounding wind flow to the critical area of the blades by designing a unique structure near each turbine.”

no excuse not to build nuclear power plants - the auroran sunset

Refusing to build modern nuclear power stations as a result of the incident at Chernobyl is like refusing to buy a new Volvo because the Model T wasn’t 100% safe.

Meanwhile that new Volvo, along with the rest of the fossil fuel industry, is killing tens of thousands of people every year in the USA alone.

Even the most lurid estimates for Chernobyl are only 4000 dead for a one-off incident that hasn’t been repeated in over sixty years with hundreds of nuclear plants running around the world.

And before someone mentions the Three Mile Island ‘disaster’: there nothing leaked, nobody died, the plants are still running safely more than thirty years later.

The watermelons (green on the outside, red on the inside) and their foolish blocking of nuclear power are the real cause of global warming, bad air and the consistent year-on-year death and low quality of living that result.

Greenpeace and their fellow travellers should be tried for conspiracy to kill.
