Small steps in solar energy efficiencies make a giant leap for solar power

An “overnight success” often takes decades of development. Electric lamps had a slow start in the 1880s. It took the Edison Company seven years to grow from 203 customers to 710. By 1900, ten thousand people had electric lights. Ten years later the number reached three million. One hundred years later, technological advances in lithium-ion batteries launched Tesla into a new, all-electric car company.

Significant advances are coming from improvements in existing electrochemical technologies by using new materials. These incremental advances improve battery reliability, longevity, and lower costs.

One of the most promising opportunities for future battery technology is the lithium-air or lithium-oxygen battery, which is predicted to provide three times as much power as lithium-ion batteries.

The unique properties of the lithium-air battery come from thin air.

Traditionally, the electrodes in batteries are made of metal or metal oxides. One electrode is replaced with air that flows in and out of the battery. It is a weightless substance, cutting battery weight in half. The other electrode in the next-gen batteries will be made of near-pure metallic lithium, a lightweight element, reducing more weight.

Advanced Research Projects Agency-Energy (ARPA-E) – a branch of the U.S. Department of Energy presented data at their March 17, 2018, energy summit that states it achieved its breakthrough technology in seven years.

Ellen Williams, ARPA-E’s director, and the spokeswoman said: “I think we have identified some holy grails in batteries.”

Many of the projects incubated by the agency are attracting private sector funding. In fact, Bill Gates and 24 other billionaires have committed to spend $2 billion on energy research.

In April, MGM Resorts announced that it has signed a contract with Invenergy to build a 100 MW solar project in Nevada to power its casinos and resorts on the Las Vegas Strip. The solar farm will be on 640 acres of the Dry Lake Solar Energy Zone.

The plant is scheduled to go live by the end of 2020. The goal is to meet 90% of the electricity demand for MGM’s 13 casinos in Las Vegas, including the Mandalay Bay, Circus Circus, Bellagio, Mirage, Aria and MGM Grand resorts. In 2016, MGM completed an 8.3 MW rooftop array.

As solar farms have become commercial successes, battery storage systems developed with ARPA-E’s support are on the verge of transforming America’s electrical grid, a transformation that could unfold within the next five to ten years, according to ARPA-E. New methods for storing electricity for the grid are developing rapidly, but widespread adoption of these technologies requires detailed data about their performance, reliability, and longevity.

ARPA-E improved battery technologies for the grid are about to be tested. The goal of the testing is to quicken the commercialization of electrochemical energy storage systems from design and testing to real-world application.

The most promising developments are with large energy storage systems on the grid, including Community Solar – a leading solar farm firm that generates and supplies power at the utility level. The solar power source is from photovoltaic modules that convert light directly into electricity. This is several degrees different from solar arrays of mirrors, which concentrate solar power to produce steam to generate turbines to produce electricity. There are disadvantages to concentrated solar power systems, including mirror wobble that damages the collection structure, and reported cases of incinerated migratory birds that fly into the concentrated rays. Photovoltaic (PV) systems outnumber concentrators by nearly 40-to-1.

Most of the existing large-scale photovoltaic power stations are owned and operated by independent power producers, but the involvement of community- and utility-owned projects is increasing. To date, almost all have been supported at least in part by regulatory incentives such as tax credits. Success has brought grid parity with legacy fossil fuel systems to many regions.

Most of today’s solar PV farms are owned by independent power producers, but utility-owned projects are rapidly increasing. At the same time, technologies in solar panel efficiencies and durability have grown as fast. Today, Community Solar has massive commercial solar arrays linked and metered to the grid in Minnesota, Michigan, and New York. California leads the nation in advanced solar energy production. Chevron has a business unit focused installing massive solar panel grids on top of roofs of schools and government buildings.


The Memo Has Landed

The Hillary Clinton campaign’s Fusion GPS created the dossier.

Clinton supporters in the FBI promoted the false dossier to major U.S. news media including the New York Times, Washington Post, CNN, the New Yorker, Yahoo, and Mother Jones.

The four-page report includes testimony from a high-ranking government official that without the infamous Trump dossier, the FBI and DOJ would not have secured surveillance warrants to spy on at least one member of the Trump team.

It also claims the FBI and DOJ used media reporting to lend credibility to the dossier, while the firm behind the dossier, Fusion GPS, briefed major American news outlets to include New York Times, Washington Post, CNN, New Yorker, Yahoo and Mother Jones.

The memo shows that after former British spy Christopher Steele was cut off from the FBI, he continued to pass information, as did Fusion GPS, through Justice Department Official Bruce Ohr.  Ohr’s wife Nellie began working for Fusion GPS as early as May 2016.

It also claims evidence that Steele has a personal animus for President Trump.

McCabe knew that the FISA warrant was obtained using shady dossier and that all extensions were based on the original application. The Obama administration then used information that Hillary paid for to justify spying on . If I got that right should be game over.

The impending release of the four-page memo comes after the House Intelligence Committee voted earlier this week, over Democratic objections, to make the document public. This led to a rare and stunning rebuke from the bureau, which said Wednesday they had “grave concerns about material omissions of fact that fundamentally impact the memo’s accuracy.”

The memo includes alleged abuses involving the Foreign Intelligence Surveillance Act (FISA).

In a last-ditch objection, the top Democrat on the House committee claimed overnight that Chairman Devin Nunes, R-Calif., had made “material changes” to the memo that was sent to the White House for review.

Nunes’ office described the changes as minor and blasted the complaint as a “bizarre distraction from the abuses detailed in the memo.”

The White House has backed the memo’s release, calling for “transparency.”



Earlier Friday, President Trump unleashed an early-morning tweet at a Justice Department he said has been “politicized” by Democrats.

GOP-led House investigators believe the FBI used a dubious dossier, initially prepared as campaign opposition research for Hillary Clinton’s presidential bid, to get permission from a secret federal court to eavesdrop on Trump campaign and transition team communications.

“The top Leadership and Investigators of the FBI and the Justice Department have politicized the sacred investigative process in favor of Democrats and against Republicans – something which would have been unthinkable just a short time ago,” Trump wrote. “Rank & File are great people!”

Just more than two weeks, Republican lawmakers first drew attention to the memo, with some calling it “shocking,” “troubling” and “alarming” and one likening the details to KGB activity in Russia. They argued the memo should be immediately made public, leading to a social media #ReleaseTheMemo campaign.

Robin Williams Found Dead in His California Home

The death of the comic genius, Robin Williams, has shocked the U.S. How could such a vibrant, talented, people pleaser end it all? His Tiburon home is on San Francisco Bay, he has two movies coming out later this year. He has controlled his addictions, which could have been   his way of battling depression. He hid his sad, dark side from most of us. My wife, Pamela was struck by seeing him with a depressed, lonely gaze while having coffee by himself at a Squaw Valley cafe.

Robin was a fanatic San Francisco Giants fan, a snow boarder, and would drop in to substitute teach science at San Ramon High School.

I ran into him at San Francisco’s Marina Green while jogging in 1986. I said “Hi, Mork. Nano nano.” He laughed and waved and kept jogging.

I skied  with him at Squaw Valley 18 years later, in 2004. He was nice enough to say “Hi, Greg, see you at the top,” in front of my daughters. That instantly gave me celebrity status with Lauren and Maddie. Lauren, my eldest, is in medical school and I believe in part from watching “Patch Adams.” I’m serious. And his teacher role in “Dead Poets Society” may have influenced Maddie, my youngest daughter to study elementary education. Maybe my career in media convinced them both to do anything but be a writer or have anything to do with publishing or marketing.

“Mrs. Doubtfire” was filmed in the San Francisco Bay Area. I often walked my dog Spots by the beautiful house they rented for the movie on Fillmore.  The restaurant scenes were filmed at Bridges in Danville.  Some of the regular restaurant workers were in the movie.

I don’t know anyone who has had a negative thought of him. (Okay, maybe his first wife).

I interviewed Williams when he  kicked off his “come back” tour at Harrah’s Lake Tahoe in 2000. I chatted with him on the set of San Francisco law offices for a comedy with Billy Crystal, “Fathers Day.” Robin was wearing a patient’s garb and slippers. He said he just escaped from the mental ward. The movie didn’t come out for six months, he was playing a mental escapee. I thought he was joking.

I had a long talk with him in Lake Tahoe. He was juggling a lot of balls in the air and until now, was able to keep them from hitting the ground.

Billy helped get Robin into baseball at a Yankees game in the old park. They watched the Yankees and Marlins in the World Series in 2003.

Seize the Day. Gather the rosebuds while ye may. The late, great Robin Williams, now a dead poet.

He loved his family, including his dogs. He had a pug and Boston terrier. Take a look at Robin’s photo album on Instragram (below).
