Sustainable Technologies/​Future Energy

Hurricanes and floods are very hazardous public health impacts on grain and vegetable crops, as well as food manufacturing facilities, food warehouses, and food transporters. Specifically, crops may be affected in a variety of ways. They may be submerged in flood water, exposed to contaminants, or susceptible to mold.

Flooding is impossible to avoid completely. And as extreme flood events continue to increase in number and frequency, more communities are becoming vulnerable. One of the severe flooding is flash floods. Flash floods tend to be associated with many types of storms,

The main societies that are affected the most from water shortage are the rural areas. Supplying water to rural areas especially for developing countries is a very challenging task because the limitation is the cost affordability for construction, repair and running expenses.

Proposed design for storage of electrical energy in the form of flywheel rotation

In our efforts to move away from fossil fuels and towards forms of renewable energy there is the problem of a mismatch between the generation of energy and consumption of this energy.

Mr. Richard Phillips Feynman, a famous scientist, introduced a Brownian ratchet in his book “The Feynman Lectures on Physics” (see Figure 1). The Brownian ratchet is also referred to as Feynman’s ratchet, Feynman’s thermal ratchet and the like.
