Extracting Water from Air : Now Electricity from Air ?

Almost a year ago , I sent following email to our Cabinet Ministers :

Water above our heads [ 29 Mar 2019 ]

Extract :

Considering that most metro cities of India are likely to run out of water in next 2 / 3 years and rural women all over India have to walk 10 Km, in 40*C temperature under blazing sun for a bucket of brackish water , I urge PM – STIAC to add

“ WATER HARVESTING from AIR “ - as a mission , with highest priority

Ref : Super Moisture‐Absorbent Gels for All‐Weather Atmospheric Water Harvesting

Inventor : Guihua Yu of the University of Texas

Now , a year later , Scientists at the University of Massachusetts Amherst have developed a device that uses a natural protein to create electricity from moisture in the air, a new technology they say could have significant implications for the future of renewable energy, climate change and in the future of medicine.

Read : New Technology Generates Electricity ‘Out Of Thin Air’

Extract :

Ø “We are literally making electricity out of thin air,” says Yao.

“The Air-gen generates clean energy 24/7.”

Ø The new technology developed in Yao’s lab is non-polluting, renewable and low-cost.

Ø It can generate power even in areas with extremely low humidity such as the Sahara Desert.

Ø It has significant advantages over other forms of renewable energy including solar and wind, Lovley says, because unlike these other renewable energy sources, the Air-gen does not require sunlight or wind and “it even works indoors.”

Ø For example, the technology might be incorporated into wall paint that could help power your home. Or, we may develop stand-alone air-powered generators that supply electricity off the grid. Once we get to an industrial scale for wire production, I fully expect that we can make large systems that will make a major contribution to sustainable energy production.”

Dear Dr Jaishankarji, [ eam@mea.gov.in ]

Recently, you set up : New, Emerging and Strategic Technologies [ NEST ] division

I urge you to ask NEST to consider “ acquiring “ the technologies mentioned above
