As mentioned above, some ruthenium complexes are able to oxidize water under solar light irradiation.
The integral of solar irradiance over a time period is solar irradiation or insolation.
He envisioned "solar cooling" by commercializing the technology in places with plenty of solar irradiation.
The steam is generated by concentrating direct solar irradiation onto a linear receiver which is 7.40m above the ground.
This would be because there would be no difference in the amount of solar irradiation received, year-round, anywhere on Earth.
With this difference in solar irradiation received, climate should noticeably change throughout the year, each year.
The difference in average solar irradiation received by the earth due to these 'random' events, though, is only about 0.1 percent.
The total solar irradiation received by Earth's surface can be calculated mathematically.
Equatorial solar irradiation and access to water would enhance this option still further.
There are a variety of factors that determine plant growth (solar irradiation, nutrients in the soil, etc).
