1. Waterless Washing Machine – Laundry Orb
New inventions have made strainful works always easier for people. Let us take an
example of a washing machine. In early days, people used to wash their own clothes by
hand and scrub all the dirt away using a brush and detergent. Later, the washing
machine was invented, which simplified laundry cleaning. The device was further
developed to produce semi-cleaners and lately fully automatic washing machines.
A new concept has been introduced by a a designer named Elie Ahovi, which works
under the principle ofmagnetic levitation.
The device, named as “Laundry Orb” consists of a spherical drum that cleans clothes by
scrubbing them using dry ice, instead f water. The spherical drum is basically a ring filled
with batteries. These batteries produces magnetic levitation inside the ring. To levitate, a
super-conductive metal laundry basket is introduced inside. A low temperature is
required inside the ring. This is produced by using liquid nitrogen. A double layered
shatterproof glass is also introduced inside. Thus, the whole drum levitates as soon as a
magnetic field is produced. The whole process is controlled using a touch screen
interface.
The dry ice is introduced inside the ring at supersonic speeds. As soon as it hits the dirty
clothes, the carbon dioxide interacts with the dirt and separates them from the clothes.
The dirt is then collected and filtered out through small pores. The carbon dioxide is
then removed and re-frozen. Thus, the clothes are cleaned and dry.

2. The cleaning process will take only a few minutes. Since no water and soap is used, the
clothes are prone to look new without any wear ad tear. The environment can also be
protected to a certain extent by saving soap. Besides, we can use the surplus carbon
dioxide for something useful.
Though the whole concept sounds interesting, there are certain cons. The removing of
carbon dioxide and refreezing it requires a lot of energy.
