With an intent to serve you chilled beverages or ice creams as you look for them on a hot, sunny summer day, designer Aija Golubeva has come up with the Solar Cool cart. The cart gets its power from solar panels embedded in a membrane that produce around 35W of solar energy. So, no external power source is needed.
The removable cooling unit asks for 64W of energy for keeping the temperature standard. The tank seems to be spacious enough for storing 40 liters of icy stuff. Equipped with reversible sear, canopy, side panels for advertisements, the tricycle also touts a steel frame for rigidity.
