Artificial photosynthesis energy conversion efficiency (due to photosynthesis' own low efficiency in converting sunlight to biomass), the cost of harvesting and transporting the fuel, and conflicts due to the increasing need of land mass for food production. The purpose of artificial photosynthesis is to produce a fuel from sunlight that can be stored conveniently and used when sunlight is not available, by using direct processes, that is, to produce a solar fuel. With the development of catalysts able to reproduce the major parts of photosynthesis, water and sunlight would ultimately be the only needed sources for clean energy production. The only by-product
Liquid latex The fumes from the ammonia in liquid latex can irritate the eyes when used as special effect make up on the face. For this reason it is recommended that liquid latex be allowed to vent for several minutes before being applied in this way. Appropriate liquid latex safety guidelines should be followed before the cosmetic use of liquid latex. Latex is a natural ingredient that comes from rubber trees in the form of a milky liquid. There are thousands of species of plants that produce different types of latex, including the Chicle tree that yields the raw material for producing
