Burn Baby Burn

So my daughter and I had an interesting conversation the other day. We'd been on a date - we went to see "Warcraft" (her choice) and ate at Zupas (her choice) - and as the only place we could find in Utah that was playing the film Monday afternoon was in Pleasant Grove, we had a nice long drive together as well. It was a very pleasant evening.

During the drive, we'd passed by some homes with photo voltaic cells on the roof. You've seen them - they're usually called "solar panels"...


...and she asks me - dad, why don't we have more of these kinds of systems in the world?

We talked about how the world needs energy, and that right now the cheapest form of energy is burning stuff to make electricity. People have been burning things forever. We burn wood for heat and light, for cooking meals and communication, and for protection and even celebration. We burn coal for heat as well, but also for use in manufacturing and electricity production. We burn natural gas for heat and electricity production. We burn gasoline in our vehicles to get us and our stuff around. And we burn oil for heat and electricity as well. It's not new - and although it's become more efficient, we're still burning stuff. With all of the attendant pollution and climate impacts.

It's gotten better - our cars are much more efficient and clean than they have been, and our coal-fired plants are either being phased out or replaced by natural gas, which tends to be much cleaner. But there seems to be an ingrained, almost fundamental need for humans to burn stuff. Which is very interesting to me.

So to switch to something that doesn't involve burning to release energy, we need an attendant fundamental shift in how we perceive, collect, and utilize energy.

More solar energy hits the earth in one hour than the whole world uses in one year. This is a pretty dramatic number, and surely the energy thus expressed is largely unavailable for convenient or practical collection, transmission, and use. However, this map shows the relative sizes of collection facilities that would be needed to produce the energy we need (the black dots represent the actual area of land that would be needed to put into photovoltaic farms to generate the energy we need):

It's clear that some of these areas are easier to access than others, and a great deal of international cooperation would be needed - energy supplies are a vital national interest, so this kind of consolidated approach may not be feasible. But even spread out across the several nations, we're looking at something that seems possible, provided we could find the political will to do it.

Which would also involve a fundamental shift in how we access, store, and use the energy thus produced. The production of the energy itself is where we may need to find the biggest shift - we need to quit burning stuff.

And as my daughter and I discussed all of this, she really began to inspire hope in me - hope that maybe that shift is underway, that people are starting to realize that we don't need to be dependent on burning things to create the energy we need, and that maybe we can look forward to a future that is efficient and clean.

Which leads me to this article:

 This is encouraging as well. Mr. Musk is a true visionary - he's able to see beyond what currently is and he has the means to put it into effect. Which I think is encouraging. And it makes me want to buy a Tesla... :)

Ephesus

Paul got around. Ephesus is right on the Aegean Sea, on the coast of present-day Turkey. Yesterday he was in Galatia, which was much more towards the middle of Turkey. And when he actually wrote these letters, he was in Rome... So the man could travel. He probably walked. Today's item of interest comes from chapter one in Ephesians. Verses 18 and 19 are particularly interesting: 18 The eyes of your understanding being enlightened; that ye may know what is the hope of his calling and what the riches of the glory of his inheritance in the saints, 19 And what is the exceeding greatness of his power to us-ward who believe, according to the working of his mighty power This is not the first time Paul talks about an inheritance. In Galatians he talks about the inheritance that comes of being part of the Abrahamic Covenant. He notes that we are joint-heirs through and with Christ. In Ephesians, he uses the word "adoption" - that we are adopted as the Children of Jesus Chris...

Engaged

Three Dog Night got it wrong.  One is not the loneliest number. They were more accurate when they said Two can be as bad as one.  I really wonder how people can survive Without being fully engaged. How they live through each day Without the intimacy I so very much crave... Maybe I am unusual in my desire  To have this intimacy, To want to feel that soul So close to my own Sharing light and warmth, Sharing love and passion, Sharing life. Alas! Alas! Alas! For when I do seek to share It is often only to be rebuffed Denied Or used up, Sucked dry, And left an empty husk.  I want SO MUCH to share And all I have is the cold, digital world Of typing out a blog.

Lucky!

So Tomorrow is Amie's birthday. The 12 th is Andy's. The 14 th is Alex's. And the 26 th is mom's. Happy birthday everyone. I recently found that a member of our ward has been diagnosed with pancreatic cancer. Pancreatic cancer has a survivability rate of less than 5% and you never, ever kick it, even if you live. Once diagnosed, people are expected to live about six months. My wife and I were talking about this wonderful woman. There are very few (too few) people in this world who shine. Literally. This sister shines with a light that is perceptible and discernible . The world will literally be a darker place without her in it. Life is short, folks. Too short for hard feelings, too short for pain and misunderstanding. I love you all so much. Sorry this one is such a downer... I don't mean to be lugubrious on your birthdays... I consider myself lucky to be your brother. You have and continue to bless me and my family in many ways, for which I will be eternally gra...
