THE MOON FACE EXPLORATION AND ELECTRIC WHEEL CHAIR

  The recession in America and the corruption of her rival 
Soviet Union caused the slow down of the trial of the flying
to the moon. But in course of time, standards flight to the
moon and the investigation on the surface of the moon will 
start. 
  It seems that there are a close connection between the 
moon surface exploration cars which are popular space 
machines and the electric wheel chairs for heavily disabled 
people which have rapidly developed recently.
  I have heard that some parts of the electric chair such as
the light and durable framework materials and control boxes 
are the application of space science. 
  The most common point is the electric motor. The gasoline 
can't be used on the moon where there is no air.
  I have a lot of expectations for the modern technology 
such as lightning of a battery and extending the flying time
. Could the downsizing of the solar battery release us from 
the nuisance job, i.e., charging battery?
  I saw in the science fiction movie or something, the 
exploration car which is like a spider or a green hopper, 
passing on the crater and sands by bending three or four 
pairs of long legs.
  If the cars can be made more compact, and is applied for a
electric wheel chair, it can go over the steps and graveled
road easy.
