1.   Because the truth would emerge as soon as you converted the energy into a different form.

2.   He showed converting energy from the sun into useful forms was scientifically possible.

3.   In effect, they convert the energy of the electromagnetic radiation into chemical energy.

4.   Local doses are often underestimated and plexiglass shielding converts some energy into penetrating gamma radiation.

5.   The sensing element of a scintillation counter is a fluor, a substance capable of converting radiation energy to light energy.

6.   No energy is converted into heat during the cycle and so no damping is experienced.

7.   The first law of thermodynamics tells us that energy may be converted from one form to another without any of it being destroyed.

8.   However, when energy is converted from one form to another, some of it is wasted.

9.   All these provide indirect means of converting solar energy to forms of energy which are useful to us.
