A potentially important breakthrough in energy production was announced by lbl labs today.
Researchers have discovered the structure of how plants convert sunlight into usable energy.
If we could manufacture these structures and place them in water-filled panels, sunlight could be directly converted to hydrogen. This would short-circuit the bio-fuels path by going directly to hydrogen instead of cultivating crops. This would be more efficient and require no fertilizer or cultivation. An added bonus is that the hydrogen gas can be stored and used when needed, unlike solar cells.
