Energy and Power

Energy is measured in Joules. Power is measured in Watts. Energy is how far you can run. Power is how fast you can run.

When it comes to batteries, Elon Musk says, "It’s really rare that there’s a big breakthrough because there are so many constraints. You can easily improve, say, the power, but then it’d make the energy worse."

Current electric cars have batteries that provide less power and less energy. This is why the Nissan Leaf has a range of only 84 miles (one-third that of the Tesla Model S) and takes three times as long to get to 60 miles per hour.

Musk's Tesla Gigafactory, being built outside Reno, Nevada, will be the second-largest building in the world by volume. It opens in 2016 and will be complete during 2020. His plan is to build enough batteries to reduce the price and improve the power and energy of batteries, so electric cars can go faster and farther. (The latest edition of the Model S received a score of 103 from Consumer Reports, which was a problem only in that Consumer Reports ratings are typically scored out of 100. The magazine had to revise its scale in response to the record-breaking result.)

In addition, the plant will produce large batteries that store energy in homes and even larger batteries that do the same for utilities and businesses. One of its goals is to make home and business solar power more practical. Current prices are already half what other battery manufacturers charge. Musk says, "The issue with existing batteries is that they suck. They’re expensive. They’re unreliable. They’re stinky. Ugly. Bad in every way." His new battery plane are on the path to fix those problems.

In addition to CEO of Tesla Motors and Space X, Musk is also the chairman of solar energy provider SolarCity.

Whitening Toothpaste Myth

"Scientifically proven" labels on toothpaste containers are not entirely accurate. According to the American Dental Association, whitening toothpastes may be able to do something on the surface level. To get to the deep-down stains, you need more extreme treatments like bleaching. Several whitening toothpastes are available over the counter and have received the ADA Seal of Acceptance.

The ADA recommends that if you choose to use a bleaching product, you should only do so after consultation with a dentist. This is especially important for patients with many fillings, crowns, and extremely dark stains.

Since December 31, 2007, professionally (such as dentist) applied bleaching products are no longer eligible for the American Dental Association Seal of Acceptance.

Travel Tip

If you travel, those little hotel room packets of coffee are perfect to use in your bag with dirty laundry and at home for room odors. Unwrap the foil covering and toss unused coffee packet in with your dirty laundry. When you get home your bag will be less stinky. Leave the coffee packet in your bag while storing it for your next trip.

Using Google Voice

Users of Google’s voice-control features such as OK Google are probably aware that the company stores the voice recordings it receives when they talk to it. Did you know it keeps a list of all the recordings the company has ever made of you. If you have or have ever had an Android phone with Google’s “OK Google” voice-control system, the link below will show a list of every command you have ever given it, including a play button next to it. https://history.google.com/history/audio

Google also has a location history, showing any location the company has tracked you to, through apps such as Google Maps as well as simply using an Android phone. It can be found here https://maps.google.co.uk/locationhistory/b/0

Happiness and Bars

Here is a quick read about how to "Spend Time at Your Local Bar to Build Community and Your Own Happiness." Researchers at Oxford’s Department of Experimental Psychology explain there are social benefits to being a regular at a small local bar. LINK

Happy Friday

"There are two distinct classes of what are called Thoughts:
those that we produce in ourselves by reflection and the act of thinking,
and those that bolt into the mind of their own accord." ~Thomas Paine

Thoughts from reflection and thinking make up my Friday Thoughts blog entries.
Happy Thoughts immediately bolt into my mind when I wake up on a Happy Friday!

Ivrea Festival

It is celebrated during the first week of February in Piedmont, Italy. It is a huge food fight, consisting of men and women throwing oranges at each other.

The purpose is to pay tribute to a battle that happened in 1194 when the Mugnaia (miller's daughter) decapitated Raineri di Biandrate, the town Count. It may have begun with the tossing of beans, but somewhere along the way changed to oranges. Sounds like great fun.

Happy Anniversary Al Gore

Bad News: It’s been 10 years since Al Gore predicted in “An Inconvenient Truth,” we had just 10 years to save the planet. I think we are still here.

Time and Time Zones

According to the Oxford English Dictionary, time is the most frequently used noun in the English language, and year is the third most frequently used noun. Person is the second most used noun.

The world is divided into about 40 time zones, including 27 hourly time zones. In addition, there are several time zones of just 30 or 45 minutes apart.

China and time zones - Despite being larger than mainland United States in terms of land area, China has one single time zone (UTC+8).

Mainland United States is divided into four time zones.

France has 12 time zones, most of which are in its overseas territory. The country of France itself observes a single time zone.

Russia, The world's largest country has eleven time zones. Daylight saving time is not used in Russia.

Canada, the world's second largest country, has six time zones.

Antarctica and the Arctic are the only areas where all standard time zones currently followed in the world, converge. Amundsen–Scott Station on the South Pole however uses New Zealand time (UTC+12 and UTC+13 during DST).

Wordology, Eschatology

It is a sub-field of a variety of disciplines including Theology, Philosophy, and Physics that deals with the end of the World or end of time.

Robot Progression

According to a research study by Tractica, annual shipments of consumer robots - a category that includes robotic vacuums, lawn mowers, and pool cleaners as well as social robots - will increase from 6.6 million units in 2015 to 31.2 million units worldwide by 2020 with a cumulative total of nearly 100 million consumer robots shipped during that period.

The fastest growth will occur in robotic personal assistants, a category that is nascent today. According to the report, "the next 5 years will set the stage for how these robots could fundamentally transform our homes and daily lives."

China, Japan, and South Korea are responsible for 40% of all new robot installations. China has more than 25% of all annual installations. The world market for robots grew 17% during 2015 and has had steady growth since 2009. Indications are that this growth rate will continue.

It used to be that the largest market for robotics was the United States. By 2014 China took over as the single largest market. During the past two years it had 50% annual growth in terms of new robot installations. China still has much below average installations of robots per capita. The maturity of a market is typically compared by number of robots installed per 10,000 workers in the manufacturing industry. Mature industries, such as automotive, will typically have 1 robot for every 10 workers.

South Korea has the most robots for manufacturing with 478 robots per 10,000 workers. Japan is second with 314 per 10,000 workers. Germany is at 292, USA is at 164. The world average is 87. China is currently at 36. Even with twice as many robots sold, China would still be below average in its use of robots.

Calories are Calories

A few years ago, for a class project of 10 weeks, Mark Haub, a professor of human nutrition at Kansas State University, ate sugary foods for his meals. To add variety in his stream of Hostess and Little Debbie snacks, he munched on Doritos chips, sugary cereals, Oreos, Twinkies, Nutty bars, and powdered donuts.

His daily intake included : Doritos Cool Ranch: 75 calories; 4 grams of fat,
Kellogg's Corn Pops: 220 calories; 0 grams of fat,
whole milk: 150 calories; 8 grams of fat,
baby carrots: 18 calories; 0 grams of fat,
Duncan Hines Family Style Brownie Chewy Fudge: 270 calories; 14 grams of fat,
Little Debbie Zebra Cake: 160 calories; 8 grams of fat,
Hostess Twinkies Golden Sponge Cake: 150 calories; 5 grams of fat,
Centrum Advanced Formula From A To Zinc vitamin: 0 calories; 0 grams of fat,
Little Debbie Star Crunch: 150 calories; 6 grams of fat,
Hostess Twinkies Golden Sponge Cake: 150 calories; 5 grams of fat, and
Diet Mountain Dew: 0 calories; 0 grams of fat.

His premise was, "In weight loss, pure calorie counting is what matters most - not the nutritional value of the food." (Not the best for lifelong intake, but an easy diet.)

A man of Haub's pre-dieting size usually consumes about 2,600 calories daily. So he followed a basic principle of weight loss and consumed less than 1,800 calories a day.

The result - Haub's 'bad' cholesterol, or LDL, dropped 20 percent and his 'good' cholesterol, or HDL, increased by 20 percent. He reduced the level of triglycerides, which are a form of fat, by 39 percent. In addition, the premise held up as he dropped 27 pounds during the course of his diet.

Cemetery and Graveyard

Graveyard and cemetery do not mean the same thing. From about the 7th century, the process of burial was in the hands of the Church (the organization), and burying the dead was only allowed on the lands near a church (the building), the churchyard.

The part of the churchyard used for burial is called a graveyard. As the population of Europe started to grow, the capacity of graveyards was no longer sufficient. By the end of the 18th century, the unsustainability of church burials became apparent, and completely new places, independent of graveyards, were devised. These new places were called cemeteries.

Cemetery comes from Old French cimetiere, which meant graveyard. The French word originally comes from Greek koimeterion, meaning 'a sleeping place'.

Bottom line, a graveyard is a type of cemetery, but a cemetery is usually not a graveyard.
