Harvard new nontoxic Battery

Harvard new nontoxic Battery Team

By modifying the structures of molecules used in the positive and negative electrolyte solutions, and making them water soluble, the Harvard team was able to engineer a battery that loses only one percent of its capacity per 1000 cycles.

Harvard scientists have developed a new flow battery which stores energy in liquid, works 10 years without energy loss and is much safer than lithium-ion batteries.

After a few years of heavy use, most lithium-ion batteries suddenly loose a lot of storage capacity. You surely recognize this from your smartphone, but that’s also a problem for energy storage which should last a very long time to store solar energy. Scientists at Harvard University have found a possible solution.

The new technology promises a battery definitely lasting ten years without losing much capacity. The solution is applied to a so-called flow-battery. The flow battery stores energy in organic molecules dissolved in neutral pH water. This new chemistry allows for a non-toxic, non-corrosive battery with an exceptionally long lifetime and offers the potential to significantly decrease the costs of production.

Professor Daniel G. Nocera (Harvard) has succeeded in changing bacteria genetically so that they can absorb CO2 and convert it into alcohol.

This news has been reported by the American magazine Forbes. But, according to Nocera:

this bacteria does not solve the CO2 problems.

Keith – Solar Footprint

Keith - Solar Footprint

Keith sayd that he had long been skeptical about the solar hype. ‘I was wrong’.

The solar hype is getting real. For a long time, Harvard professor David Keith was skeptical about solar energy. But now he admitted he was wrong.

Keith: “Solar energy is very cheap and it can change the future of the global energy supply within a decade.”
