Towards A Global Government

India has rolled out the biometric ID to almost its entire population. On top of that it has added a layer that works like Jack Ma's Alipay, only Alipay is in the private sector, the Indian version is in the public sector. Voting from the phone should become possible and private. Facial recognition technology minus possible abuse can be harnessed for safety and security. Digital makes business and vehicle registration easy. Solar energy is dropping in price at a dramatic pace and is set to blow open the number one constraint for the Global South's desire for prosperity: energy. When Musk puts over 4,000 satellites into orbit in a few years, you are looking at gigabit internet from every point to every other point on earth. Taking good care of earth will become possible. Much progress seems to be technology driven. But it is the human being that has to be placed at the center of the progress.

A world government has been long overdue. But it will soon become possible, and soon enough become inevitable. The first step might be to create a bicameral legislature in New York. In the lower house each member country has a voting weight in proportion to its population. In the upper house it is in proportion to its GDP. Each member country pays 1% of its GDP in tax. That makes the world government's budget. The President of the World is required to garner a majority in both chambers, limited to two five year terms. Eventually when at least half of humanity has biometric IDs and can vote from mobile phones, the President of the World can be directly elected. Local, state, federal, global -- these would be the four layers of government everywhere on earth, except where the country might be too small, or too homogenous for a federal setup.

The world government is not the UN. It is a new thing, just like the UN was not the League Of Nations. There will be a President Of The World. There will be a global parliament. There will be a World Court. There will be the three branches. All global institutions will be subsumed by the world government.

This century is not the American, or the Chinese, or the Indian, or the Asian, or the African century. This is the global century. All world will become one country. The basic needs of all human beings will be met. Primarily because the Age Of Abundance is right around the corner, much of it technology driven.

Multinational corporations are already global, finance has long been global, but there is not the robust political framework. That robust political framework will also be good for the MNCs, also for global finance.

In The Tech News (2)

Forget Rocket Fuel: This Spaceplane Will Use Microwave Beams to Reach Orbit
We probably shouldn’t be shocked when a giant column of highly combustible material accelerates to thousands of miles an hour and explodes. ..... Escape Dynamics .. an “external propulsion” spaceplane that separates energy from propellant. Instead of volatile liquid or solid rocket fuel, the craft runs on pressurized hydrogen. A ground antenna array aims a beam of microwaves at a heat exchanger in the plane’s belly, superheats the hydrogen to 2,000 degrees kelvin, and forces it out of an exhaust nozzle to provide enough thrust to reach orbit. ......

Ultimately, they hope to build a reusable single-stage-to-orbit spaceplane that would slash launch costs for small satellite payloads and remove combustion from the equation entirely.

.... In tests, their lab-scale prototype thruster achieved efficiency higher than anything possible using chemical rockets. ..... The idea of external propulsion is by no means new. It was proposed by Konstantin Tsiolkovsky nearly a century ago, and NASA and Caltech have since toyed with the concept. ..... there is growing demand for small payloads. With powerful, miniature sensors and chips, we’re now able to pack quite a bit more tech into much lighter satellites ...... Startups like Planet Labs (the company assembling a constellation of Earth observing satellites) or Google (building out global internet infrastructure) stand to benefit from the cost savings Escape Dynamics would offer if successful...... because a spaceplane glides back to Earth, instead of the hard-to-control freefall of a rocket stage, reusability may prove an easier nut to crack. .... a lot more affordable. .... launch costs are in the ballpark of $25,000 to $50,000 per kilogram. He’s a fan of the alternative approach: “Escape Dynamics is pursuing a radical technology—one I fundamentally think is a good idea—which could massively reduce the costs for small satellite payloads.” ....... Once they start regularly flying payloads, Tseliakhovich estimates costs could eventually fall by two orders of magnitude—perhaps reaching as low as around

$150 per kilogram

. ..... Tseliakhovich hopes his company will begin flight tests of a small-scale thruster in 2017 and launch their first payload to orbit at the turn of the decade. ..... Tseliakhovich believes it will likely work alongside heavy-lifting chemical rockets and is a huge fan of current efforts to improve them by the likes of Elon Musk and SpaceX. ("One of the most remarkable efforts pursued by our civilization today.")

Scientists Connect Brain to a Basic Tablet—Paralyzed Patient Googles With Ease
eye- or head-tracking devices have allowed eye movement to act as an output system to control mouse cursors on computer screens. In some cases, the user could also perform the click function by staring intently at a single spot, known in the field as “dwell time.” .....

In contrast to eye-trackers, neural prostheses directly interface the brain with computers, in essence cutting out the middleman — the sensory organs that we normally use to interact with our environment.

..... had a 100-channel electrode array implanted into the left side of her brain in regions responsible for movement. ...... “This is a first step towards developing a fully-capable brain-controlled communication and computer interface for restoring function for people with paralysis.”
Our Solar System’s 9 Extraterrestrial Oceans in One Surprising Infographic
Not too long ago, we only suspected one ocean of liquid water beyond Earth (on Europa). Now, thanks to robotic explorers, like NASA's Dawn and Cassini missions, we're finding evidence of oceans throughout the solar system. ...... water (especially liquid water) and life go hand in hand ..... life, at least the simplest forms, may survive in more environments than once believed. Indeed, even on Earth, life is ubiquitous, from scalding volcanic vents to frozen wastes. And we may not, as it turns out, need to travel light years to find extraterrestrial oceans or observe our first alien life forms ...... news of even a few nearby alien microbes would expand the number of nooks and crannies life might inhabit throughout the galaxy.

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.

Space Travel And Showing Skin

Planets of the Solar System

Space travel damages skin but makes hair grow FASTER: 'Astromice' study discovers the lesser-known impacts on astronauts
some astronauts experience skin dryness and itching after spending time in space - making them more vulnerable to scratches and irritation...... the astronaut underwent an accelerated skin ageing process in space...... ‘Weightlessness as experienced by astronauts during space flights affects physiological functions of the human organism that has evolved, like other organisms living on Earth, through continuous adaptation to the permanent gravitational field.’ ...... a study on 19 crew members of six Nasa-Mir missions from 1995 to 1998 indicated small skin injuries were the most frequent medical incidents including dryness and itching. ..... several cutaneous physiological changes were recorded after the mission such as coarsening and decreased skin elasticity ....... there might be more detrimental effects than thought on missions into deep space, such as to Mars

I have known this all along. We are not supposed to travel vast distances. We are supposed to take good care of earth. Maybe moon, maybe Mars. But there is nothing much going on either on Moon or Mars. Other than having a backup plan that might be needed a million years from now, I don't see the point. What would it take to recreate Tribeca or Chinatown on the moon or Mars? A lot. You will probably ended up creating a parking lot up there.

There is a reason why everything out there is measured in light years. We are supposed to stay back and measure, use telescopes and things, take in the incoming information if we ever got so curious. We are not supposed to go there. We are supposed to stay put.

I get the impression we experimented on people before we experimented on mice. Beware, time travels faster for the skin out there.

But if this is only about gravity, Mars has gravity. As long as you can survive the journey and make it fast, you should be okay. Right?

Internet Satellites? Now You Have My Attention, Elon

Mars is esoteric to me. I already know what's on Mars. Earth is way more exciting. Glad to have you back on earth, Elon.

$100 Billion Plan To Save The World
Elon Musk’s Next Mission: Internet Satellites
Elon Musk shook up the automotive and aerospace industries with electric cars and cheap rockets. Now, he’s focused on satellites, looking at ways to make smaller, less-expensive models that can deliver Internet access across the globe ..... launching around 700 satellites, each weighing less than 250 pounds ...... it would cost $1 billion or more ..... hopes to bring the cost of manufacturing smaller models under $1 million
