## Abstract

A potable water making apparatus includes a thermoelectrical cooling plate, air intake, and a separator. The thermoelectrical cooling plate is operable with electrical power to form a cool surface. The air intake guides the air from a surrounding across an area of the cooling plate, and the separator drives condensation from the cool surface to a reservoir.

## Claims

### Claim 1

A potable water making apparatus comprising:
a thermoelectrical cooling plate that is operable with electrical power to form a cool surface;
an air intake to guide air from a surrounding across an area of the cooling plate; and
a separator to drive condensation from the cool surface to a reservoir.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the thermoelectrical cooling plate is a Peltier plate.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein the separator is a sonic agitator.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the separator is a piezo pulser.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein the separator is a solenoid.

### Claim 6 (depends on 1)

The apparatus of claim 1, further comprising:
a purification mechanism provided with the reservoir to purify the collected condensation.

### Claim 7 (depends on 6)

The apparatus of claim 6, wherein the purification mechanism includes an ultraviolet light.

### Claim 8 (depends on 1)

The apparatus of claim 1, further comprising multiple thermoelectric cooling plates which are stacked.
