Water scarcity to hit half Mankind by 2050

Water, water everywhereAccording to researchers from the Massachusetts Institute of Technology, ” by 2050 more than half the world’s population will live in water-stressed areas and about a billion or more will not have sufficient water resources. “

” (…) The researchers expect 5 billion of the world’s projected 9.7 billion people to live in water-stressed areas by 2050. They also expect about 1 billion more people to be living in areas where water demand exceeds surface-water supply. “

The threat is, as you can imagine, to be exarcebated by global warming and increasing water demand. Lucky us, there are solutions to both problems.

Hiriko, the folding electric car

Here is a new article I wrote for Cleantechies : ” Cities are facing many problems, including the lack of parking spaces and air pollution. Regular electric vehicles would solve the air pollution issue, but not the parking one.” ” This is probably why the (MIT worked on a folding electric car codenamed CityCar. The … Read more

Toward super efficient solar panels

I came across two news today that could revolutionize solar panels by drastically increasing their efficiency. Given the current potential of this energy source with today’s technology, tomorrow will be bright for solar ! To the MIT Technology Review :” Replacing flat panels with three dimensional structures (see left) can significantly change the economics of … Read more

90% more efficient air conditioning

As the world is heating up because of global warming we need more air conditioning systems. This is why the latest invention from the U.S. National Renewable Energy Laboratory may change the world.

Indeed, to the MIT Technology Review, the NREL have created ” a new air-conditioner design that (…) will dramatically increase efficiency and eliminate gases that contribute to global warming. “

Using indirect evaporative cooling, and desiccants this invention would use up to 90 percent less energy and wouldn’t need CFCs to operate.

Temperatures could rise by 7°C by 2100

Climate change, aka global warmingAccording to a new study by the Massachusetts Institute of Technology (MIT) climate change may reach 7°C by the end of this century. This doubles the previous estimates by the IPCC.

As climate models become more and more complex and contain more and more data, the results are increasingly worrying. I hope this study will lead our leaders to act in Copenhagen.

I wonder how Mankind and Life on Earth in general would react to such an important rise of temperatures. It took only 2°C more of global average to come from the previous Ice Age.

A new MIT technology to produce hydrogen

I never have been a fan of hydrogen-based energy solutions. Indeed, using energy to produce hydrogen that will produce electricity seems a tad too complex.

This may change with Professor Daniel Nocera from the renowned Massachusetts Institute of Technology (MIT) who found a fantastic solution to produce Hydrogen in a much more efficient way.

This would make intermittent energy sources like solar and wind power much more interesting as one of their main drawbacks would be solved.
