Solar energy is a popular topic today, and plants provide us with ideas for efficient collection of sunshine energy. During photosynthesis, sunlight converts carbon dioxide into water and sugars which nourish the plant. Worldwide, the daily rate of solar energy absorption by vegetation is six times greater than the output of all the world’s power plants.

Sugar beets provide 30 percent of the world’s sugar. At refineries, the sugar is extracted and a liquid residue remains. In the upper Midwest, it was noticed that this residue, placed in holding ponds, did not freeze under wintry conditions. Chemical studies reveal a natural antifreeze chemical in the beets. This design feature protects the growing beets themselves from the cold, and also caught the attention of highway crews.

The biological hydrogen production with algae is a method of photobiological water splitting which is done in a closed photobioreactor based on the production of hydrogen as a solar fuel by algae.
