What you're seeing here is a water filtration system.

You've got gravity, you've got the centrifugal force, you've got the fluid dynamics.

And in this one, plants are used for the water filtration ability.

Depending on the oil used, the filtration step leaves a protein rich filter cake, which could be used as animal feed or for human consumption.

The rest turns into a stable compound, which survives filtration into the water systems, thereby exposing the very aquatic birds that would carry flu and providing them a chance to breed resistant strains.

For cholera, he suggested the use of bole hole drills for capturing water, the employment of activated charcoal domestic water filtration systems, and the establishment of locations for disease screening and medical care.

Still others might need deeper reservoirs, more modern filtration plants, or improved water transport schemes. These can all potentially be designed to improve and expand water supplies for power generation, irrigation, and household and industrial use, while providing security against droughts and protection from floods.

Historical precedents indicate that forcing disparate nations and states to unite under a single idea whether communism in the Soviet Union, socialism in Yugoslavia, or a shared currency in the eurozone generates centrifugal forces that can trigger the union s collapse. A one size fits all approach to integration is simply unsustainable.

A final advantage of this solution is that it would be temporary. Historically, confederations sooner or later either become federations (as occurred in the US, Germany, and Switzerland) or, pushed by centrifugal forces, split up (as with the United Arab Republic, established in 1958, which split three years later into Egypt and Syria).

These conflicts have taught Africa that, in order to contain the centrifugal pressures that encourage fragmentation within our relatively new states, a conscious effort must be made to nurture and entrench national unity, which must include democratic practices. Conflict has also communicated the unequivocal message that unity cannot be secured and maintained by force alone.

Anyway, there we were, staring at each other, and he reaches down and grabs an armful of gravel and releases it in the jet of water entering the tank from the filtration system, and chk chk chk chk chk! this gravel hits the front of the glass and falls down.

Cyberwarfare is proving to be as threatening to political and economic stability as conventional military conflict. At the same time, technologies like water filtration systems, drought resistant seeds, renewable energy, and the Internet have the potential to fulfill the basic needs of a crowded planet better than any empire could.

Perhaps the most important aspect of a conference is its purposes, which all participants should identify for themselves. An individual or organization may attend a conference to understand the future of bottled water, to find procurement managers who buy bottled water, or even to disrupt the bottled water market with water filtration systems.

The European integration process has, at its core, always been values driven and rules based two qualities that are on retreat in today s world. By carrying the banner of liberalism, good governance, and the rule of law internationally, the EU can reverse the centrifugal forces at home that have intensified during the crisis, thereby strengthening its capacity to respond to today s challenges and securing its position in tomorrow s world.

In fact, many useful innovations, such as energy generating building materials and zero emissions transportation, already exist they simply need to be made accessible to those who need them most. Devices like small scale water filtration systems, portable heart monitors, and low cost tablet computers are already dramatically improving the lives of the world s poorest citizens and helping to level the economic playing field.
