Space Based Solar Power













I myself am still pretty big on Sahara though. Space might be 10 times more efficient, but it might be 20 times more expensive, at least now. But I will go to space for clean, why not? Space based solar power also has potential for colonizations of the moon and Mars and beyond. It would make large scale 3D printing possible. Ocean covered moons of planets like Jupiter could give water if energy is plentiful. Water and solar and you are that close to growing food.

Space-based solar power
a higher collection rate and a longer collection period due to the lack of a diffusing atmosphere and night time in space
Space-based solar power: the energy of the future?
In space there's no atmosphere, it's never cloudy, and in geosynchronous orbits it's never night: a perfect place for a solar power station to harvest uninterrupted power 24 hours a day, 365 days a year. ..... the concept is scientifically sound. ..... there was nothing wrong with the physics but the real question is the economics ...... With costs as high as $40,000 per kilogram for some space launches, the final price-tag for the first space-based solar power station could be as high as $20 billion. ........ the wars in the Middle East gave new impetus to the space-based solar power as scientific researchers with the military wrestled with the problems of delivering energy to troops in hostile areas. ........ Multiple, and potentially hidden, receivers could tap space-based solar power and relieve the military of the expensive and often dangerous task of supplying troops with generator diesel by either road or air ...... Two proven ways of getting the power to Earth exist in the form of either laser beams or microwaves. ...... laser transmitting satellites would have difficulty beaming power through clouds and rain. ...... The microwave option would have the advantage of uninterrupted transmission through rain, hail or any other atmospheric conditions and could provide gigawatts of power........ as early as 1964, scientists were able to power a helicopter using microwaves. Dr Jaffe said with a large receiving area the energy from the microwaves was so dissipated that it would present no danger to life. ......... as many as 100 launches into space would be required to construct the space stations with costs running into tens of billions. ...... space-based solar energy is like most novel ideas. "It's hard to tell if it's nuts until you've actually tried."
Space-Based Solar Power
Microwave transmitting satellites orbit Earth in geostationary orbit (GEO), about 35,000 km above Earth’s surface. Designs for microwave transmitting satellites are massive, with solar reflectors spanning up to 3 km and weighing over 80,000 metric tons. They would be capable of generating multiple gigawatts of power, enough to power a major U.S. city. ...... The long wavelength of the microwave requires a long antenna, and allows power to be beamed through the Earth’s atmosphere, rain or shine, at safe, low intensity levels hardly stronger than the midday sun. Birds and planes wouldn’t notice much of anything flying across their paths. ........ The estimated cost of launching, assembling and operating a microwave-equipped GEO satellite is in the tens of billions of dollars. It would likely require as many as 40 launches for all necessary materials to reach space. On Earth, the rectenna used for collecting the microwave beam would be anywhere between 3 and 10 km in diameter, a huge area of land, and a challenge to purchase and develop.
What If Giant Space-Based Solar Panels Could Beam Unlimited Power To The Earth?
This idea may sound like science fiction, and at one time it was. ...... Asimov's 1941 story envisions a world where the Earth is powered by a beam of light that draws its energy directly from the sun..... Take New York City, for example, which requires 20 gigawatts of power. ...... The sandwich modules would be about 10 feet long on a side and about 80,000 would be needed. The array of sandwich modules would be about the length of nine football fields, or more than 1/2 a mile long. This is about nine times bigger than the International Space Station...... Back on Earth, the energy-containing radio frequencies from the space-based solar panels would be received by a special antenna known as a "rectenna," which could be as big as six miles in diameter............ the same beam would be able to provide power to Seattle and redirected to provide power to Rio de Janeiro in Brazil...... they could build receivers at remote operating bases and locations where it is logistically difficult and incredible costly to deliver diesel fuel....... the incredible heat of the sun in space
China considering space-based solar power station
Some believe a space-based solar collector could be launched as early as 2020 ..... a satellite that weighs more than 10,000 lbs., dwarfing anything previously placed into orbit, including the International Space Station ...... others place the launch date further out, as far away 2050. ...... "China will build a space station in around 2020, which will open an opportunity to develop space solar power technology" ...... China should begin with an experimental space-based solar power station by 2030, and build a commercially viable space power station by 2050. ....... "An economically viable space power station would be really huge, with the total area of the solar panels reaching five to six square kilometers" ....... Six square kilometers is nearly twice the size of New York's Central Park. ....... The Japan Aerospace Exploration Agency (JAXA) has proposed its own solar collector to be launched within the next 25 years. ...... "When space solar energy becomes our main energy, people will no longer worry about smog or the greenhouse effect" 
Space solar is a very real option, but it will not happen in time to tackle Climate Change. For that we need to rely on Earth Solar. Let's just use satellites for internet communication.

Kurzweil's Schedule

Raymond Kurzweil

In his estimate, current exponential growth of computing will continue until human-level intelligence is achieved around 2029. Merging with artificial intelligence will then follow, sometime in the 2030s as humans will be "a hybrid of biological and nonbiological thinking," wherein we connect our brains to the cloud to harness massive computational power. Beyond that? "As you get to the late 2030s or the 2040s, our thinking will be predominately nonbiological. The nonbiological part will ultimately be intelligent and have such vast capacity it'll be able to model, simulate, and understand fully the biological part. We will be able to fully backup our brains."
Elon Musk and Ray Kurzweil have a fundamental disagreement. Kurzweil thinks Artificial Intelligence is a faster, better computer. Musk thinks it is a nuclear weapon.

Exponential Finance: Financial Advice In the Age of AI and Long Life
most financial advisors as we’ve known them won’t be around much longer. ...... in the next ten years, half of all the financial advisors in this country will be gone ...... Not unlike other industries, like medical diagnostics, for example, artificial intelligence may soon perform many of the technical skills of financial advice better than their human counterparts. ...... AI won’t soon replace the uniquely human relationships clients seek from the best advisors. ...... “We are therapists, counselors, marriage consultants, and psychologists as much as we are financial planners” ...... Charles Schwab disrupted the industry back in 80s, putting many traditional stock brokers out of business. But they reinvented themselves as wealth planners. ..... “You don't see financial planners and financial advisors using a slide rule or a calculator and a number two pencil and a yellow pad.” ..... one of the greatest challenges they face is convincing their clients that instead of planning to live to 95—which is as far as financial planning software goes at the moment—they should plan to live longer. Perhaps much longer. ...... the first person to reach age 150 has already been born ...... Chances are, if you make it another 30 years, you'll make it another 100 ...... Instead of the traditional linear progression—birth, school, job, retirement, death—our lives will become more cyclical. That is, we’ll go to school, get our first job, work for awhile, take a five- or ten-year break, and then go back to school to reinvent ourselves and start our next career cycle. Rinse and repeat. ...... Discrete college degrees, he thinks, will be replaced with lifelong learning.
A lot of that recycling needs to happen already even before people have started living longer.

Digitizing Money For The Poor

I have an enormous interest in finance for the people at the very bottom. I think magical advances are possible. And there is also a lot of money to be made.


Exponential Finance: Who Will Be the Instagram or Uber of Finance?
Instagram was acquired for a billion dollars the same year Kodak went bankrupt. Though Kodak invented the digital camera behind Instagram’s business model—they failed to fully embrace it and paid the price. Uber is a five-year-old transportation company worth $40 billion, and they don't own a single car or bus. ....... relatively small organizations are rapidly rising up to take on big traditional players with little more than an app on a smartphone. So, what models are leading contenders to become the Instagram or Uber of finance? ..... As smartphones become ubiquitous in the developing world, it's possible many of the world’s unbanked billions in developing countries will skip traditional finance, a little like how they leapfrogged landlines for cell phones. ....... bank-free, digital cash will be a force to be reckoned with. ........ blockchain’s potential is massive—not just for cryptocurrencies, but anything of value. The same technology that records and confirms Bitcoin transactions can, in theory, do the same thing for “a will, a deed, a title, a license, intellectual property, an invention, or any type of financial instrument.” ...... Machines doing what machines do best, and humans doing what humans do best. Better together than either one alone. ...... By more fully digitizing finance (parts of it are, of course, already digitized), we can supercharge commerce and reduce the cost of doing business. ...... Even now, the digital camera market is shrinking as point-and-shoot cameras are replaced by smartphones. ...... Reality has surpassed science fiction.

I think I would like to live past 100. What about you? I have seen pictures in newspapers of people who have done it without any Singularity type help. All of them were slim though.

If you do exercise, you can be as vibrant at 80 as you are at 40, almost.

How Computers Will Crack the Genetic Code and Improve Billions of Lives
Machine learning and data science will do more to improve healthcare than all the biological sciences combined. ..... the most epic challenge — extending the healthy human lifespan ..... Your genome consists of approximately 3.2 billion base pairs (your DNA) that literally code for "you." ..... Your genes code for what diseases you might get, whether you are good at math or music, how good your memory is, what you look like, what you sound like, how you feel, how long you'll likely live, and more. ..... Each person's genome produces a text file that is about 300 gigabytes. ...... The genome of the 100 trillion + microorganisms living in our bodies. There are 10 times as many microbial cells than human cells, and their effects on our bodies are enormous and massively understudied........ With millions and millions of documents/websites/publications online that were already translated, and a crowd of 500 million users to correct and "teach" the algorithm, GT can quickly and accurately translate between 90 different languages.
