RWH

Rain Water Harvesting. Rainwater harvesting is the accumulating and storing, of rainwater. Rainwater harvesting has been used to provide drinking water, water for livestock, water for irrigation or to refill aquifers in a process called groundwater recharge. Rainwater collected from the roofs of houses, tents and local institutions, or from specially prepared areas of ground, can make an important contribution to drinking water.

Installing RWH in one's house, saves water.

RWH

Raging White Hole - A raging white hole is the opposite of a Black hole, only is more aggressive than a standard White/Black hole, hence why it is labelled as "Raging".

No one has encountered these holes in this universe or any other alternate universe out there but maybe one day we will find a RWH.

It is said to appear randomly in the popular multiplayer online game known as "Runescape" but is unconfirmed. The scientists of RS are commonly on the look-out for RWHs to appear.
