Barsha pump provides irrigation water, but doesn't need fuel

A Barsha pump at work in Nepal 

Climate-KIC, a European-union climate innovation initiative, recently selected a jury of entrepreneurs, financiers and business people to award funding to what they felt were Europe’s best clean-tech innovations of 2014. Taking first place was Dutch startup aQysta, a Delft University of Technology spin-off company that manufactures what's known as the Barsha irrigation pump. It can reportedly boost crop yields in developing nations by up to five times, yet requires no fuel or electricity to operate.
Although the Barsha pump (Nepalese for "rain pump") is a new product, it's based on a very old design – it has its origins in ancient Egypt.
The pump itself is essentially a water wheel on a floating platform, that's moored in a nearby flowing river. The moving water rotates the wheel, that in turn utilizes a spiral mechanism to compress air. That air drives water through an attached hose and up to the fields.

It's claimed to be capable of pumping water up to a height of 25 meters (82 ft), at a maximum rate of one liter (0.26 US gal) per second. According to its designers, it has zero operating costs, only one moving part, can be built from locally-available materials, and should provide a return on investment within one year of use – for diesel-powered pumps, they claim that the figure is closer to 10 years.
Of course, it also creates no emissions.
The first Barsha pump was set up in Nepal this July, and a business is now being established there to manufacture and market the devices. Plans call for similar developments in Asia, Latin America, and Africa.

Flagstaff House religiously skewed – Bawumia


Alhaji Bawumia

The running mate of the Opposition New Patriotic Party Dr. Mahamudu Bawumia has stated that the Presidency is religiously skewed.

According to him, the seat of government does not adequately reflect one part of the two dominant religious groupings in the country.

Addressing supporters of the New Patriotic Party in the Sissala East district of the Upper West region, the former deputy governor of the Central bank urged the residents to vote for the NPP in the upcoming elections in order to bring religious balance to the presidency.

“Another major issue that I want to bring to the attention of the people is that; if we look at the flagstaff house today, it does not reflect the people of Ghana in terms of religion.

“We are in this country living peacefully and nicely; Christians and Muslims. So we believe in the NPP that Christians and Muslims should work together and that is why whenever we pick a flagbearer as a Christian, we pick a Muslim as a vice. And when we come and pick a Muslim as a flagbearer, we will pick a Christian as a vice.

"So if, Insha Allah, Nana Akufo-Addo becomes president, he will swear with the Bible and enter the Flagstaff and I will swear with the Quran and enter the flagstaff House,” he noted.

Currently, Ghana’s President John Mahama and his vice, Kwesi Amissah-Arthur are both Christians.
