Five Fatal Flaws of Solar Energy
American Thinker, by Viv Forbes

Original Article

Posted By:magnante, 7/25/2014 8:58:27 AM

The sun is the most important energy source on Earth. Solar energy powers the growth of all trees, grasses, herbs, crops and algae; it creates the clouds and powers the storms; it is the source of all hydro, photo-voltaic (PV), solar-thermal, bio-mass, and wind energy. Over geological time, it also creates coal. PV solar panels are useful in remote locations and for some portable applications. With enough panels and batteries, standalone solar can even power homes. But solar energy has five fatal flaws for supplying 24/7 grid power. Firstly, sunshine at any spot is always intermittent and often unreliable. Solar panels can deliver

The ultimate, most effective, smallest footprint, and cleanest (lowest emissions per generated energy) source known to man already exists...nuclear. But it has been and continues to be blocked by Luddite environmentalists.

Well thought out article.
Batteries are still the same lead acid devices from the early 1900´s.

Advances are occurring. Prices are coming down. Stand alone private applications, are only twice as expensive as the grid. Plus your house will always be in the shade...

Having lived on a boat dependent on solar, wind, and generated power, the article hits the high (low) points very well. Storage is always the big issue. Now that the obama epa has forced the last USA lead smelter to close, where will all the lead come from for all those batteries- which last, at most, eight years?

The first paragraph outlines the importance of Solar Power the way the creator set it up. All efforts to augment this technologically are doomed to failure because the overall nature of the system is not designed for that.

Economic and safe transportation and storage are the "weak links" in most of these alternative energy approaches. It is still hard to beat the energy storage capacity and ease of transport of a gallon of gasoline, a cubic-foot of natural gas, or a ton of coal.

In general on earth, you can get about 1 watt of usable year around power from 1 sq ft. of solar panel. You will need storage for at least 18 watt hours per sq foot of panel, 48 is much better.
Example - a modern house WITHOUT air-conditioning and a $100 monthly electric bill would be using about 30 KiloWatt Hours of electricity a day. Thus you would need about 1250 sq feet of solar panels on a south facing roof (about 65´ x 20´) and about 50 deep cycle batteries for storage. You also need some fairly hefty inverters and chargers (read expensive). If you want air conditioning - better double that. Oh - don´t forget the backup generator.

The sad thing is, these facts have been known since the solar movement started. Solar supply will ALWAYS have limitation. The battery problem might get better with technology. Panels may become a bit more efficient. Solar solutions in targeted areas might be practical.

But solar is NOT, and probably will never be, a "grid" source solution. If magic technology does make it practical, the market will flow to it.

Also, while pilot projects can be subsidized, subsidies for broad based use are fiscal insanity.

The problem the greenies face is that there is no practical substitute for carbon fuels or nuclear which they hate. So all their solutions lead us to powerless futures. Only a tiny percent of the public thinks that is OK.

So to get real, carbon and nuclear are our future, no matter what the consequences. Could we manage a planet 5 degrees warmer (which there is no proof of)? Yes. Could we manage a planet without power? No.

Would it be wonderfully Utopian to have plentiful power from the Sun? Sure. But it´s a pipe dream.

State Department won´t say how missing,

A spokesperson for the State Department refuses to say if any missing contract files from March 2008 - March 2014 were stored electronically. The American Thinker began covering the case of the missing records for $6 billion on April 5, 2014, soon after the State Department’s Office of Inspector General released two unclassified memos dated March 20, 2014. (snip)The fact that Hillary Clinton was the Secretary of State for four of the six years covered by the missing files may explain the reluctance of the State Department to answer simple, factual inquiries about the missing records.

Ever since the Republicans regained control of the House in 2010, some conservatives have sought to replace Rep. John Boehner as speaker. Boehner has managed to fight off challenges to his leadership in the past. But there appears to be a serious revolt brewing among a growing number of conservatives who are unhappy with Boehner´s approach to the 2014 mid terms. The Hill thinks that the current challenge to Boehner is the most serious to date: The strategy — for now — seems disorganized and fluid: Find a way to push the Speaker’s race to a second ballot, create turmoil in the conference,

Navy used 47 Tomahawks last night,
47% of planned 2015 purchases

Last night’s air strikes against ISIS in Syria used up 47 Tomahawk missiles. The Tomahawk is an extremely effective weapon, capable of delivering its ordnance precisely, without risking a pilot’s life. But the defense cuts of the Obama administration call for procuring only one hundred Tomahawks next year. Christopher Cavas of Defense News reported last May: Weapons procurement showed striking reductions from last year’s plans. Then, the Navy planned to buy 980 Tactical Tomahawks, the primary cruise missile in use throughout the fleet. The new plan shows only 100 missiles in 2015 and none thereafter.

Rotherham has made its splash, had its fifteen minutes and is gone, assuredly with a sigh of relief from the media and politicians on both sides of the big pond. For thirteen years, something on the order of 1400 girls in Rotherham, a typical Midlands industrial city of roughly a quarter-million, were carefully groomed and then turned out as whores by members of the city’s Pakistani Muslim minority. The motive of the Muslims is transparent: Mohammed said it was okay. The reaction of the city’s populace is less so. For thirteen years, not a government official, not a policeman, not a

President Obama and his fellow Democrats are scheming to use immigration and housing policy to fulfill their dream to fundamentally transform America forever. (snip) Obama is transforming America through immigration. There is an even more calculated policy being followed. To see the impact look at a map: The influx into the south is changing the political alignment in southern states. The South has been a bastion for Republicans for years but that has made it a target and it is under assault.

The Utter Failure of Obama

Barack Obama is destined to be the greatest flop in American presidential history. He is, in every sense of the word, an utter failure. Consider first his signature achievement, Obamacare. Not only has Obama had to delay implementation, creating a perfect precedent for his Republican successor to do the same, but the law is more unpopular today than it has ever been according to all polling data.

ince the U.S. is largely moderate to conservative, it was hard to imagine how someone as far left as Barack Obama twice won the presidency. After the election was over, we learned how the Democrats’ data mining operation succeeded in bringing to the polls the outlying constituencies he needed to win (given the normally low turnout of the rest of the voters). Part of that mining for voters involved targeting messages designed to emotionally appeal to them, given that “belief” once formed in these peoples’ minds defeats any rational arguments. The big (and unfortunately successful) target of these emotional appeals was

The National Security Advisor of the United States did something astonishing yesterday. In the middle of a reporter’s questioning, she bolted from the podium of the White House pressroom, saying, “Nice to see you,” fleeing a situation she evidently was unable to cope with. The question that caused Ms. Rice to flee was a fairly simple one: whether or not the president has authorized the bombing of targets in Syria. Rice responded multiple times that the timing of strikes would not be released, but that was not the question at hand, and reporters pressed her on whether her boss had authorized

President Barack Obama returned a formal military salute with a one-handed coffee-cup salute Tuesday, only a few hours after he dispatched the nation’s military on their attack mission into northern Syria. White House aides posted the sloppy salute video on Instagram. The commander in chief offered the coffee-cup salute when he disembarked from his U.S. Marine Corps helicopter in New York, as he made his way to the United Nations General Assembly. “President Obama just landed in New York for #UNGA2014,” says the caption. The salute is “the most important of all military courtesies,” says a manual for Marine Corps officer candidates. “In some situations,

President Barack Obama saluted a pair of United States Marines on Tuesday while holding what appeared to be a styrofoam cup in his saluting hand, a breach of military regulations that won´t win him fans among veterans and servicemen. Obama is known for drinking tea, not coffee, when he travels, especially before delivering speeches. His quasi-saluting gesture was an instant embarrassment for the White House, and not because his environmentally taboo drinkware clashed with the green-policy speech he was on his way to deliver at a UN Climate Summit.

On Tuesday, shortly after announcing to the American public that the United States was now bombing ISIS in Syria, the President of the United States flew to New York to address the United Nations – on climate change. His speech mixed high-flown sentiment with apologies for America, and pledged American sacrifice in the name of a lofty goal without evidence that such sacrifice would in any way contribute to attaining that goal. In other words, it was a typical Barack Obama whirligig. Even as American warplanes struck targets in Syria, even as regimes tottered in Jordan and Iraq and Yemen,

Rush Limbaugh apparently tips generously, which sometimes makes people who dislike him feel quite awkward. In one case, a waitress-turned-award-winning-author revealed that she felt so awkward, that she donated both of his $1,000 tips to an abortion charity. Merritt Tierce, whose debut novel Love Me Back chronicles her time at a high-end Dallas steakhouse, revealed in an interview with Dallas News that, at the time, she was also the executive director of the Texas Equal Abortion (TEA) Fund, which provides financial assistance to low-income women seeking abortions.

If there is one thing Chelsea Clinton is most worried about, it may be that her soon-to-be child will grow up in a world without elephants. Standing alongside her mother, Hillary Clinton, at the Clinton Global Initiative this afternoon, the very-pregnant former first daughter warned the plight of African elephants, killed for their ivory tusks, is an “existential” one, and said that if the current poaching rates continue, elephants could be few and far between within the next decade. If so, this means Chelsea Clinton’s favorite animal could be something her child would never know. “The child Marc and I

During the Bush administration, national Democrat leaders threatened to kill the ABC network´s broadcast license if a miniseries unfavorable to the Clinton administration wasn´t censored to satisfy Democrats. ABC complied. Earlier this year, Democrats started a push for a Constitutional Amendment to gut (literally) the First Amendment. Over the weekend, Democrats launched a campaign to get -- in their own words -- "Rush Limbaugh off the air." The petition to get Limbaugh off the air comes straight from the Democratic Congressional Campaign Committee (DCCC) in the form of a fundraising/petition email. The idea is to use the muscle of the

The Republican Party’s top leader in Congress is catching flak for a comment that appears to call the jobless lazy – a comment that has rekindled an old challenge for the party: appearing insensitive or uncaring toward Americans who are poor or in financial difficulty. House Speaker John Boehner was asked after a speech last week to comment on a plan for addressing poverty – promoted by a Republican colleague, Rep. Paul Ryan of Wisconsin. Speaker Boehner gave a response that was favorable toward Representative Ryan´s plan, but not so favorable about Americans’ work ethic.
