Indian Company Creates Ceramic Device That Cools Rooms Down to 23 °C Without Relying on Electricity, With Low Cost and Easy Production.

Amidst rising climate challenges, a simple and accessible solution emerges in India. The company Manoj Patel Design Studio, located in Vadodara, Gujarat, has developed ceramic coolers that operate without electricity and can reduce indoor temperatures from 32 °C to 23 °C.

Evaporation-Based Technology

The concept is not entirely new. The so-called evaporative coolers have been known for years in the low-cost sustainable technology sector.

They help keep products fresh from the field to the final consumer, aiding in preventing post-harvest losses and food spoilage in areas without constant access to electricity.

Simple and Efficient Design

Each unit contains a top reservoir with a capacity of 15 liters of water. With this amount, the device can operate for 10 to 12 days without needing to be refilled. The prototypes take up little space and come in two main versions.

The first model is larger, has a water level indicator, and an automatic irrigation system. In this model, the potted plants receive water automatically through drip from a central opening.

The second model is designed in a more compact, portable lateral cone shape, making it easier to transport and use in different locations.

Low Cost and Local Production

According to Manoj Patel, the units can be produced quickly and locally, with an estimated cost of around 800 Indian rupees, equivalent to approximately 10 dollars. This amount represents less than two days’ wages for semi-skilled workers in India, making the solution financially accessible.

Diverse Applications in Hot Regions

In addition to residences, Patel plans to make the larger models available in his home state of Gujarat, where temperatures can reach 45 °C during the summer.

Applications also include remote areas without access to electricity, bus stops, train stations, street vendors, and public sectors such as hospitals and offices. Positioned in the direction of the wind, the devices offer even more effective cooling.

A third version, still in development, will be adapted as a refrigerated cage for pet birds.

China has begun the second phase of energy assistance to Cuba with a 120 MW solar generation plan, and the first result is a photovoltaic park with batteries that regulates voltage, controls frequency, and provides local autonomy to an island suffocated by chronic blackouts.

Germany installed vertical solar panels on a lake in Bavaria, and the result broke conventional logic: instead of producing energy at midday peak, the plant generates more early in the morning and in the evening, exactly when families turn on appliances and factories are in full swing.

Seismic sensors around the world detected a monotonous hum that lasted for 9 consecutive days, a signal unlike any earthquake ever recorded, and when scientists finally traced the origin, they discovered that an entire mountain had collapsed into a fjord in Greenland.
