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.
