Solar Energy Summary

It might be an idea to summarise the *Solar Energy category in Pharoz and put some of these posts into the Becrux (Mimosa) blog with links to the relevant Pharoz posts.The basic categories would be something like: Energy efficiency at a network level Storage of electrical energy Transport of electrical energy Fixing electrical energy Transverse horizontal wind turbines Transition from coal power to renewables (system wide) Carbon dioxide – Removal, transformation and disposal of CO2 Applying usable kinetic energy to spacecraft through remote lasers There is a separate post for each of the broad categories above with links to the relevant Pharoz posts.

Transport of electrical energy

2/10/2008 Solar Collector Satellites Some Pharoz posts: 24/10/2006 Solar Farms 10/04/2006 Analog to digital energy transmission *** The basic idea is that the light from a laser made with a gas will be at a frequency such that the light from that laser can be absorbed by that same gas in a special cavity at a distance removed from the laser, and thus cleanly catch the energy from the laser so to speak.

Transverse *Horizontal* Wind Turbine

A quick look through the Wikipedia pages for wind turbine designs shows that there is a general difference in design between turbines with a horizontal axis of rotation or those characterised with a vertical axis of rotation.

Transverse Wind Turbines

It’s worth exploring these kinds of ideas for transverse wind turbines to see if they might have advantages over conventional wind turbines. The alternatives are considered and some new ideas, while sounding improbable themselves, may lead on to other ideas that are more realistic.

A simpler angle of attack

Another idea is to have the axis of rotation perpendicular to the wind direction rather than in line with the wind as with conventional wind turbines. When the airfoil is closest to the ground the angle of attack for the airfoil is set to lift upwards and once it is at the top of the cycle the angle of attack could be set so that the wind pushes the airfoil downwards.

Fixed airfoil wind power

The lift from the airfoils make the airfoil sway from side to side and this could change the pressure of a fluid that is pushed by the swaying airfoil from side to side through a turbine, and thus generating electricity.

Wind Turbine Tweak

Energy might be extracted from wind turbine blades spinning at slightly variable speeds from motion of the blades moving alternatively forwards and backwards, rather that all the energy being extracted from the rotation of the blades.

Congratulations Kevin Rudd, PM Elect

The main theme in Australian politics, that I think will emerge over this time, is the manner in which Prime Minister John Howard departs from politics, and the legacy he leaves behind. Howards legacy may turn out to be in reverse to what he may have hoped, defined in opposition to his best efforts.

Instruction-set surfaces

Imagine if you could design a compound that when excited by a photon of a specific frequency the additional energy from that photon moves around in that compound but dissipates or is mechanically damped in one direction only;

A semblance of gravity

If people become accustomed to living in space in a situation similar to earth with a downward acceleration like gravity due to centrifugal forces, they would become accustomed to seeing fixed stars in constant and fast motion around them with only the polar star, planet or object directly above or below the circle or spiral being stationary, like a pole star on earth.

Sound Laser analogy

If a satellite did fire a laser at a spacecraft and the momentum of the spacecraft changed, would there be a corresponding change in momentum for the satellite that sent the energy to the spacecraft through the laser?

Transmitting kinetic energy through lasers

If you could have such kinds of lasers that could work to apply suitable amounts of kinetic energy to spacecraft, it may be possible to set up networks of ground based, satellite or even moon based stations that could move spacecraft around in a coordinated way.

Industrial scale CO2 sinks

Removing carbon dioxide from the atmosphere through pre-industrial means, by only planting trees for example, can not keep pace with the carbon dioxide emissions that our modern society is placing in the atmosphere. A carbon dioxide sink is a process that takes carbon dioxide, as well as other things such as water and energy, and turns the chemical components of carbon dioxide into something else.

Removing CO2 from the atmosphere

The important point is that renewables are needed to push these power stations into zero CO2 emission power stations or even to turn these power stations into net CO2 sinks.

Environmental politics

Perhaps if conventional power stations of today are progressively retrofitted to 1) capture CO2 and temporarily store it, and then 2) strip the carbon out for solid disposal of the carbon, perhaps powered through solar energy, then, perhaps 3) power stations might be able to continue operating as plants to remove CO2 from the atmosphere when they are no longer required for fossil fuel energy production.

Generating knowledge

Sometimes with research into novel phenomena or technologies, researchers seem to work backwards. The research dead ends will be forgotten and the knowledge will be presented as if there was a logical straight path through all this research to what we will all know will work in hindsight.

Rollie-pollie politicing

Energy security is about having energy storage to such a capacity to meet your energy needs, as well as a way to replenish the energy that is used in a timely manner. A superficial analysis of energy needs and energy security would fuse the issues of energy storage and energy sources.

Paradigm shifts

What is happening with these new ideas and perspectives on this blog could be described as possible beginnings of paradigm shifts, similar to what has happened occasionally in the sciences.
