A method III using the heat uf tLC
sun 10 place of coal and wood has been
perfected BY Or. William Calrer oi
Washington 10 such degree that 1t il
now proposed 10 make practical test
OF i on q large scale. a company has
been formed for the purpose OF using
the heat Of the sun to furnish steam
power for lrrigating purposes ID the
arid lands or the southwestern part Of
the country. The Inventor or this
method Of producing heat has been ex.
perimenting along these lines for the
past 70 years, and In his lavatory at
the end OF the North Capitol street
railway line the apparatus which he
uses Is In operation whenever the sun
shines.
DR. Calrer has also thought our
Plan Of supplying heat on days
wien the sun Is not visible. and he
proposes 10 accomplish this hy storing
up the heat In a reservoir from which
he can draw as II Is needed, says the
Washington Star He says heat can
be stored just as cold Ia the form OF
Ice is stored. However. his invention
Is a means or utilizing the heat from
tie sun. and. as Is broadly stated. II Is
by the use Of mirrors, which are So ar
ranged that heat from the suns rays
are gathered ZIP and focused at one
point.
