There are many of technological wonders in Guatemala, but a water heater is the most remarkable and pure revelation.
Aqua Caliente is an issue. Respectable Inns always note that they have Aqua Caliente. Very Respectable Inns inform you that they have a Real Aqua Caliente.
Personally, I didn't experienced Very Respectable Inns, so can't say anything about Real Hot Water, but I constantly asked about Aqua Caliente everywhere I hoped to stay for a night or few. Therefore, a water heater is familiar to me.
In pseudoscience terminology it sonorously-named "Bare Wire Technology"
Nothing can beat it: 2 bare wires meet in the jar – one “plus” and another “minus”, together making some electricity. Jar fills with running water which supposed to come warmer at the exit. Well… hot water? Not really. The positive side of this scare construction - there are no victims, at least I didn't hear somebody got injured.
Another technology wonder is an orange peeler machine!
An orange is placed into the clamps, which are then tightened into place — little spikes stick into the orange’s peel to keep it steady — and then a crank is turned, the orange spins on its axis, and a small scoop is moved down a track which takes away the peel.
This machine is made from solid steel - unbreakable!
There are spiral-sharpened oranges - the surrealist result of meeting with peeling machine.
Usually they are sold in halfs and you can keep it on the skeeny "bottom" - it is less clumsy way to eat them.
The next one looks like hurdy-gurdy (street organ), but it's an ice chopper, actually.
