The world’s most efficient and environment-friendly solar cells

Posted by in categories: nanotechnology, solar power, sustainability

In the future, solar cells can become twice as efficient by employing a few smart little nano-tricks.

Researchers are currently developing the environment-friendly of the future, which will capture twice as much as the cells of today. The trick is to combine two different types of solar cells in order to utilize a much greater portion of the sunlight.

“These are going to be the world’s most efficient and environment-friendly solar cells. There are currently solar cells that are certainly just as efficient, but they are both expensive and toxic. Furthermore, the materials in our solar cells are readily available in large quantities on Earth. That is an important point,” says Professor Bengt Svensson of the Department of Physics at the University of Oslo (UiO) and Centre for Materials Science and Nanotechnology (SMN).

Trump Should Make Space-Based Solar Power A National Priority

Posted by in categories: solar power, space, sustainability

My take on why the Trump Administration should make space-based solar power a real priority.


Space-based solar power — technology that would harvest solar energy directly in space for use on Earth — is a concept whose time has come.

Automation that could take away human jobs can also open the massive resources of the solar system

Posted by in categories: employment, robotics/AI, space travel, sustainability

Massive and complete automation could enable industrializtion of the moon and space. By using some larger human colonies along with the robots then it would be more robust and less dependent on perfect automation.

Advances in robotics and additive manufacturing have become game-changing for the prospects of space industry. It has become feasible to bootstrap a self-sustaining, self-expanding industry at reasonably low cost. Simple modeling was developed to identify the main parameters of successful bootstrapping. This indicates that bootstrapping can be achieved with as little as 12 metric tons (MT) landed on the Moon during a period of about 20 years. The equipment will be teleoperated and then transitioned to full autonomy so the industry can spread to the asteroid belt and beyond. The strategy begins with a sub-replicating system and evolves it toward full self-sustainability (full closure) via an in situ technology spiral. The industry grows exponentially due to the free real estate, energy, and material resources of space. The mass of industrial assets at the end of bootstrapping will be 156 MT with 60 humanoid robots, or as high as 40,000MT with as many as 100,000 humanoid robots if faster manufacturing is supported by launching a total of 41 MT to the Moon. Within another few decades with no further investment, it can have millions of times the industrial capacity of the United States.

Blockchain can dramatically reduce pollution and traffic jams

Posted by in categories: bitcoin, cryptocurrencies, Elon Musk, energy, environmental, futurism, sustainability, transportation

The World Economic Forum has posted an article that hints at something that I have also suggested. (I am not taking credit. Others have suggested the idea too…But advancing tech and credible, continued visibility may help us to finally be taken seriously!)

I am not referring to purchasing and retiring carbon credits. I like that idea too. But here is a blockchain idea that can enable fleets of autonomous, shared, electric vehicles. Benefits to individuals and to society are numerous.

The future is just around the corner. Non-coin applications of the blockchain will support many great things. Goodbye car ownership. Hello clean air! The future of personal transportation.

Scientists Have Found a Crazy New Way to Print on Paper Using Light

Posted by in categories: nanotechnology, sustainability

A new method for printing on paper using light promises to be much cheaper, and easier on the environment than the traditional ink-based printing we’re used to.

Scientists have developed a special nanoparticle coating that’s easy to apply to normal paper and changes colour when ultraviolet (UV) light shines on it. The colour change can be reversed when the coating is heated to 120 degrees Celsius (248 degrees Fahrenheit), and allows for up to 80 rewrites.

The team of researchers from the US and China say that their new high-resolution light printing technique could be used everywhere from newspapers to labels, saving on the cost of ink and paper, and on the environmental cost of their recycling and disposing.

China’s New “Weather-Controlling Tech” Could Make it Rain on Demand

Posted by in categories: climatology, sustainability

In Brief

  • China has spent $168 million on cloud seeding technology to hopefully manipulate the weather and combat drought and extreme weather due to climate change
  • Cloud seeding technology has existed for a long time, however because of early false claims and deep-rooted skepticism, there isn’t sufficient research to back up the tech

The China Meteorological Administration wants to increase rainfall and snow across 960,000 square kilometers of the country. A more effective way of making this happen that doesn’t involve a ritualistic rain dance? Spending $168 million on cloud seeding technology that they hope will allow them to manipulate the weather.

Here’s how it works. The money will be invested into four new aircrafts, upgrading eight existing planes, and launching 900 rocket systems that will allow them to sprinkle substances above the clouds that could induce the rainmaking process. These substances range from silver iodide to dry ice. Adding these chemicals into clouds might lower their temperature and speed up the condensation process.

Recycling Space Junk for a LunarBase

Posted by in categories: robotics/AI, satellites, sustainability

It costs $80k to send a Nano- Satellite into space! To send the materials to build a lunar base is going to be expensive!

This week it was announced that NASA found a forgotten satellite in Lunar Orbit, which got me thinking about an idea to recycle existing Space Junk in the construction of an International Lunar Base with cost savings. We could use a modified version of my Google Deepmind NEO tracker to source the Space Junk and the ideas listed below to capture and redirect the Space Junk.
