Special nanotubes could improve solar power and imaging technology

Posted by in categories: computing, nanotechnology, physics, solar power, space, sustainability

Physicists have discovered a novel kind of nanotube that generates current in the presence of light. Devices such as optical sensors and infrared imaging chips are likely applications, which could be useful in fields such as automated transport and astronomy. In future, if the effect can be magnified and the technology scaled up, it could lead to high-efficiency solar power devices.

Engineers boost output of solar desalination system

Posted by in categories: nanotechnology, physics, sustainability

Rice University’s solar-powered approach for purifying salt water with sunlight and nanoparticles is even more efficient than its creators first believed.

Researchers in Rice’s Laboratory for Nanophotonics (LANP) this week showed they could boost the efficiency of their solar-powered desalination system by more than 50% simply by adding inexpensive plastic lenses to concentrate sunlight into “hot spots.” The results are available online in the Proceedings of the National Academy of Sciences.

Space Gets 100 Times Cheaper By 2023 and We Will Get Moon Bases and More

Posted by in categories: satellites, solar power, sustainability

If SpaceX gets a fully reusable Super Heavy Starship flying to orbit in 2020 and then has 100 fully reusable flights by 2023 then the cost of space will drop by 100 times. This will start fulfilling the plans for lunar bases, lunar mining, and space-based solar power.

If each Super Heavy Starship costs $300 million and has $1 million in operating and maintenance cost per flight then the per flight cost is $4 million. Super Heavy Starship is supposed to launch about 100 tons to orbit.

Assuming that 800 Starlink satellites are launched by April 2020, then SpaceX will start doubling its revenue from $2–3 billion to $5–6 billion in 2020 and ten billion in 2021. This will mean that SpaceX will be able to afford to build dozens of Super Heavy Starships.

Spinach power for solar cells

Posted by in categories: solar power, sustainability

Popeye would be proud.


Popeye uses spinach to power his muscles. Now, scientists are looking to spinach as a power source for making electricity.

A solar cell converts sunlight into electricity. Most of these, today, are made of a material called silicon. The new device instead uses proteins from spinach and from a bacterium called Rhodobacter sphaeroides.

KickSat: Our goal is to dramatically lower the cost of spaceflight, making it easy enough and affordable enough for anyone to explore space

Posted by in categories: biotech/medical, computing, solar power, space travel, sustainability

We can do this by shrinking the size and mass of the spacecraft, allowing many to be launched together.

Sprite

The Sprite is a tiny (3.5 by 3.5 centimeter) single-board spacecraft. It has a microcontroller, radio, and solar cells and is capable of carrying single-chip sensors, such as thermometers, magnetometers, gyroscopes, and accelerometers. To lower costs, Sprites are designed to be deployed hundreds at a time in low Earth orbit and to simultaneously communicate with a ground station receiver.
