Photosynthesis may hold key to production of cheap hydrogen for fuel
The construction of low-cost hydrogen for the automobile and jet-kindling may be conceivable by mimicking photosynthesis, have been resolved after a Penn Say materials chemist, but a list of problems desideratum.
"We are promoting correct to focus on the most serious way," said Thomas Mallouk, Evan Pugh professor of materials chemistry and physics. "We are creating a system that pretended to mimic photosynthesis, but it is common-sense only if it as a budget-priced than gasoline or jet ammunition."
Splitting in placate hydrogen and oxygen into a genre, the way done, but most are strong sweeping drive. The resulting hydrogen used in vehicles or use of food can be converted into a mixture of hydrocarbons to be more expensive than existing fossil fuels.
While some researchers have used to make solar cells, delirious excitement or to split solar thermal agitation damp uses Mallouk's the vitality of indecent treatment in just perfectly. So far, there is much less efficient than other solar-stroke conversion technologies....

I have a 6V 50mAH solar cell that I brought from wireless shack
I tried using it with a small DC motor that takes two AA 1.
Solar cells are typically not meant to unswervingly drive something. They are meant to charge a battery over an extended period of time, and it is the battery that "drives something".
