10 GBPS

This is so damn exciting.

Mark Zuck.
We've successfully tested a new laser that can transmit data at 10 gigabits per second. That's ten times faster than any previous system, and it can accurately connect with a point the size of a dime from more than 10 miles away. ..... 10% of the world’s population lives in areas without existing internet infrastructure.

Giant Tech Companies Should Give Money To Individuals And Local Governments

Silicon Valley

Big tech companies like Google should pay money to individuals whose data they cash on, and to governments in whose jurisdictions they make money in. It should be sane amounts and sane percentages, but it can't be zero.

Empire of the geeks
Silicon Valley should be celebrated. But its insularity risks a backlash .... THE English have Silicon Fen and Silicon Roundabout, the Scots have Silicon Glen. Berlin boasts Silicon Allee, New York Silicon Alley. But the brain of the tech world is the ecosystem in and around San Francisco. ...... Airbnb, a seven-year-old firm that helps people turn their homes into hotels, operates in 34,000 towns and cities around the world. ..... American capitalism has a new hub in the west. Wall Street used to be the place to seek fortunes and make deals; now it is increasingly the Valley.

The area’s tech companies are worth over $3 trillion

...... The enormous, disruptive creativity of Silicon Valley is unlike anything since the genius of the great 19th-century inventors. Its triumph is to be celebrated. ....... insularity. The geeks live in a bubble that seals off their empire from the world they are doing so much to change. ..... Many denizens of the Valley believe that tech is the solution to all ills and that government is just an annoyance that still lacks an algorithm.

The Great Math Mystery





We have six senses, not five. The fifth is the mind, expressed most purely in imagination, mathematics. Just like with our eyes we see the world in the visible spectrum, with our minds we also see a world that seems to be mathematical. The sky looks blue to us, and the world looks mathematical. We are only "seeing" what we are capable of seeing.

Life Is Just A Force Of Nature

A few months back I came across this theory online. There is the law of entropy. Things move from a high energy state to a low energy state. There is this dispersion. If you add a living being to the process, entropy is faster. And so, life is just something nature has come up with to speed up entropy. 

I thought that was amazing. Not just life, but matter and energy are amazing too. Life is amazing, compared to what? It is not like life is this amazing thing in this ocean of not-amazingness. Not true. Life is special, but then so is gravity. Does it not blow your mind as to why the earth goes round the sun? That is not life. That is just gravity. 

I think life is as abundant in the universe as stars. Just like once we thought earth was the center of the universe, we think we are the only ones alive in the universe. 

Life is just one of the forces of nature.

Why middle-aged entrepreneurs will be critical to the next trillion-dollar business
Steve Jobs was 52 when he announced the iPhone. That was in 2007. Years later, the Apple cofounder introduced the MacBook Air, App Store, and iPad. Tim Cook, who was 51 when he took over from Jobs, is building on his legacy. They both shattered a myth that the young rule the technology industry. ........ Research on successful technology firms by a team I led at Duke and Harvard in 2008 looked only at companies that had made it out of the garage and were generating at least $1 million in revenue. The research revealed that the average and median age of their founders was 39. Twice as many were older than 50 as were younger than 25. And twice as many were older than 60 as were younger than 20. In a follow-up project, we studied the backgrounds of 549 successful entrepreneurs in 12 high-growth industries. The average and median age of male founders in this group was 40, and a significant proportion were older than 50. ...... in every year from 1996 to 2013, Americans in the 55-to-64 age group started new businesses at a higher rate than those in their twenties and thirties. And the trend is building. Those ages 55 to 64 started 14 percent of all new businesses in 1996 but nearly 24 percent of them in 2013. ...... What makes entrepreneurs successful, as my team’s research revealed, is work and industry experience and management ability. These come with age. ..... The inexperience — and immaturity — of youth is one reason venture capitalists’ track record is so poor. In 2012, the Kauffman Foundation analyzed 20 years of investment data from nearly 100 venture funds. It found that the vast majority of them produced lower returns than did the public markets. ........ The experiment by Thiel to pay college students to drop out did not result in any world-changing startups. Most Thiel fellows joined other companies or went back to school. The Thiel Foundation quietly redesigned its program, which now provides an alternative education to children. Perhaps the realization set in that the innovation advantage isn’t provided by youth, but by knowledge, maturity, experience, and connections......... the average age at which Nobel laureates performed their prizewinning work and the average age at which inventors had their great achievement was 39. He also found that twice as many — 14 percent — were older than 50 as were younger than 26. Jones found that the average age of innovators is steadily rising, with the average age of greatest achievement for Nobel Prize winners and great tech inventors having increased six years, to 45, in the 20th century. ......... It also is easier to write code for a cellphone than to learn how to motivate and inspire employees, manage finances, and market products. But building a business requires all of those skills. That is why older entrepreneurs have more success. ...... A technology shift is happening that will dramatically alter the entrepreneurial landscape in the next few years. Several technologies — involving medicine, robotics, artificial intelligence, synthetic biology, 3D printing, and nanomaterials — are advancing at exponential rates and are converging. This is the same type of advance that is occurring with computers — with processing power doubling every 18 months, prices falling, and devices becoming smaller. A $500 laptop today has more computing power than did a Cray 2 supercomputer that cost $17.5 million in 1985 and had to be housed in a large building. ........ These advances are making it possible to solve the global problems of health, energy, education, and hunger. Inexpensive sensor-based devices, for example, allow the continual measurement of heart rate, temperature, movement, pressure and light. They can be used to build devices that keep track of blood pressure, glucose and blood oxygen levels, respiration and even sleeping habits. They also can be used to improve agriculture, monitor the environment and reduce food spoilage. Systems based on artificial intelligence can be used to make medical diagnoses, to drive autonomous cars, and to predict traffic patterns, crime and trends. Robotic devices will allow us to care for the elderly and automate routine processes. Digital tutors will be able to transform education. .......... These technologies will make it possible to create the next trillion-dollar industries and to better our lives. But they require knowledge of fields such as medicine, biotechnology, engineering, and nanotechnology. They require experience, an understanding of the problems people face, and cross-disciplinary skills. All of these come with age and experience, which middle-aged entrepreneurs have in abundance. That is why we need to get beyond the stereotypes and realize that

older entrepreneurs are going to better the world

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.
