Ballistic Electron Flow

Ballistic conduction is when electrons move through a medium with minimal scattering and resistance. This happens in nanowires and nanotubes because of their small diameter. Experiments confirm theory of “superballistic” electron flow – [mit.edu] The idea behind superballistic flow is that interactions among electrons make them move in a highly coordinated manner, mimicking the behavior […]

Harvesting Electricity from Normal Movement

The simplest example of the “triboelectric effect” is rubbing a balloon against hair or scuffing shoes across a carpet to produce static electricity. When this is combined with induction, it becomes possible to harvest electric power using charge transfer between two thin films that have different tribo-electric polarities. As we learn to integrate this process […]

Superfluids Can Become Supersolids

When the isotopes Helium-3 and Helium-4 are cooled to extremely low temperatures, they become liquid and exhibit superfluid properties. This means they have a viscosity near zero and can flow without losing kinetic energy. A vortex created while a fluid is in this state will continue to rotate without dissipating. Under low temperatures and pressures, […]

Making Metallic Hydrogen

Hydrogen is the simplest atom, composed of a single proton in the center and a single electron around the edge. We think of it in a natural form as a gas, but at low temperatures (-423 F) it will liquefy. Once it’s in liquid form, adding a lot of pressure (5 million atm) can force […]

Sell Mexico Solar Power Generated by Trumps Wall

Implementing this idea will be subject to political winds. But it raises the concept of using other pieces of infrastructure to collect solar power. Roads, railroad tracks, power lines, pipelines, and more structures in our society negotiate “right of way” contracts to use the land. We could be using all of these to both collect […]

Superconducting Graphene

Graphene is an arrangement of carbon atoms into a thin flat sheet that has extraordinary strength as well as being flexible and a conductor of electric current. This would seem to make it an ideal medium for electronic components. Researchers are now working to add superconductivity to the list of attributes associated with graphene. Graphene’s […]

Vortex Wind Generator Wiggles

Vortex bladeless wind generators respond to air movement by vibrating and oscillating as eddy currents curl around them. The motion created in the masts can be harnessed to produce electricity, using a linear alternator. This greatly reduces the cost of energy capture.

Superconductor Basics

When we push electrons through most conductors, there is resistance from other electrical fields that slows down the transmission of the electrical current and creates heat. In some materials, the electrons clump together in pairs (Cooper pairs) and move with reduced resistance. These materials are called superconductors and they are most effective at low temperatures […]

Molten Salt for Thermal Energy Storage

A container of molten salts can be heated from solar energy and then the heat can be used to drive turbines to generate electricity. This makes it practical to supply electric energy at night from solar energy collected during daytime. A Tower of Molten Salt Will Deliver Solar Power After Sunset – [spectrum.ieee.org] For the […]

Quasiparticles

Elementary particles are not so much discrete “balls” of matter like marbles or planets as they are “clouds” of localized characteristics. Particles are often “fuzzy” around the edges, in terms of describing their physical limits and their location in space. But we know that these clouds or lumps that we call particles can interact with […]
