Beyond air quality and climate change mitigation benefits, California abundant renewable energy resources provide energy with zero marginal cost and zero fuel price volatility to our citizens,
To avoid the perverse outcome of curtailment of zero-marginal-cost, greenhouse gas-free renewable resources, we need to absorb gigawatt-hours'worth of midday solar energy for reuse later in the day or the week.

#Solar desalination (Nanowerk News) When graduate student Natasha Wright began her Phd program in mechanical engineering, she had no idea how to remove salt from groundwater to make it more palatable,
Wright began designing an electrodialysis desalination system, which uses a difference in electric potential to pull salt out of water.
This type of desalination system has been around since the 1950s, but is used typically only municipally, to justify its costs.
While other companies are already installing desalination systems across India, their designs are intended to be powered grid.
Shes designed a village-scale desalination system that runs on solar power. Since her system is powered by the sun,
Its useful to install a small-scale desalination system where people are so spread out that its more costly to pump in water from a municipal plant,

#New study shows how nanoparticles can clean up environmental pollutants Many human-made pollutants in the environment resist degradation through natural processes,
In a new paper published this week in Nature Communications("Nanoparticles with photoinduced precipitation for the extraction of pollutants from water and soil),
while the photoinduced precipitation ensures nanomaterials are released not in the environment. Ferdinand Brandl and Nicolas Bertrand, the two lead authors, are former postdocs in the laboratory of Robert Langer, the David H. Koch Institute Professor at MIT Koch Institute
Brandl says. hen we came up with the idea to use our particles to remove toxic chemicals, pollutants,
in a solution hydrophobic pollutant molecules move toward the hydrophobic nanoparticles, and adsorb onto their surface,
and now nrichedby the pollutants they form larger aggregates that can then be removed through filtration, sedimentation,
and molecules. he interactions we exploit to remove the pollutants are nonspecific, Brandl says. e can remove hormones, BPA,
And the nanoparticleshigh surface-area-to-volume ratio means that only a small amount is needed to remove a relatively large quantity of pollutants.

But this comfort comes with a considerable environmental cost--it's responsible for up to a third of the world's total greenhouse gas emissions.
Since the waste in the wastewater (organic material) is consumed and thus removed, the water itself becomes purified,
