Introduction: A limiting factor in the use of mass transit is that rail stops are seldom close to the starting point (one's home) or the destination (work, etc.) . Parking garages fill and adequate transport is not available from the nearest stop to the final destination.
If we just use our senses we can feel the threat to our precious planet Earth. We all feel the increasing of the temperature, the abrupt climatic changes, the defrosting of the Arctic (North Pole) putting in danger the survival of so many species, especially the Polar Bear.
The future, as we see it, is powered by the Sun.
From sub-kilowatt Personal Power to multi-Gigawatt solar grid arrays, PNGinc has beaten coal pricing with a pressurized gas turbogenerator that can roll back carbon emissions & cut end user pricing to 10 cents per kilowatt-hour worldwide.
The need for green energy is increasing these days. This need may be met by incorporating one technology with another inter dependable technology.
Usually optical fibers are used to transmit data by using light as the carrier way. Likewise photovoltaic layers produce energy on exposure to light.
The energy supply of today is based on the use of fossil fuels despite their large environmental impact and the stocks of fossil fuels are diminishing. There is a critical need for developing the renewable energy technologies and the global market of solar cells is growing at approximately 50% per year.
Consequence is a medical product focused on children between 8 and 10 years.
The idea is to retrieve the user's ankle in a funny way, making the child do the exercises without any problem.
The main problem in these cases is that it's traumatic for a child to this kind of physical therapy exercises.
Concept design of a piezoelectric mat for harvesting energy from vibrations.
Piezoelectric ceramics have the property of producing electricity under compression stimulus. This mat takes advantage of that property disposing piezo electric components in the weaving structure of the fabric in a hexagonal grid.
The case is presented in the configuration of a sail,
Removing medicine from the blister packs they come in can be very difficult, especially for the elderly or those with arthritis. This inexpensive device, small enough to fit on a key chain, would make that task much easier. Think of it as a hole punch for pills in blister packs. The device would resemble a stapler in basic form,
The idea to utilize waves in elastic solids for generating rotational motion goes back to Sashida (1982) and has become widespread in mechatronic systems, for instance in photo cameras for focusing the lenses.
The basic idea behind the so called travelling-wave-type-motor are the elliptic trajectories of the surface points in the stator.
Petroleum and plastic cannot be explained discretely, as plastic is nothing but one of the many useful products derived by processing petroleum. Plastic is obtained when crude petroleum is processed and treated with a few other additives. This would basically make plastic a polymer of hydrocarbon with few other elements.
