One way that is quick and easy, if you have a digital camera is just do a drawing with pencil or marker pen, and photograph it and upload the pix file. I've done that before and it works pretty good.
...as they say a picture is worth a thousand words.
Regarding Peltier devices (from Wikipedia):

Thermoelectric junctions are generally only around 5–10% as efficient as the ideal refrigerator (Carnot cycle), compared with 40–60% achieved by conventional compression cycle systems (reverse Rankine systems using compression/expansion). Due to the relatively low efficiency, thermoelectric cooling is generally only used in environments where the solid state nature (no moving parts, maintenance-free) outweighs pure efficiency.
