Kamikaze Drone City Defence

The HESA Shahed 136 drone typically deploys in a flock (swarm) formation flying in groups of five. The cost varies but typically ranges between US $20k to $40k per drone. At a length of 3.5m and a delta wing span of 2.5m. The drone is relatively low cost compared to a typical missile cost of +$800k The Shahed 136 was designed to be a low cost loitering ammunition capable of carrying a 50kg…

99942 Apophis Near Earth Approach 2029

that was at one point in the past attributed on the Torino scale at level 4. Apophis is a 350 meter length asteroid, mean radius 185 meters and a mass close to 27 billion kg The current risk of collision in 2029 is over 1/1000000, one in a million. The current prediction of Apophis near Earth approach in 2029 is currently estimated at 370 km from Earth. As a direct threat this is low risk,…

Gravity Wave Detection - Down Under

Gravity Wave Detection – Down Under

The detection of galactic based gravity wave sources using interferometer (LASER interference) is now well established. Re LIGO Laser Interferometer Gravitational Wave Observatory. The LIGOs detector facilities within the Northern Hemisphere, located from Europe to USA provide a means of detecting galactic coordinates of Gravity Wave Pertubations. The spatial coordinate granularity could be…

Planet Arc

Where do you go when the Earth is no longer viable or approaching an extinction event such as a Cretaceous–Paleogene extinction event. Hope for the best but plan for the worst. A quote by Lee Child is all well and good, but the fact remains that there is absolutely nothing that could be done to stop any high energy impact. The ability to detect large Asteroids within the orbital plane is…

Australian Economic Pathway - Advanced Small Modular Reactors (SMRs) Combined with Value Add Mining.

Australian Economic Pathway – Advanced Small Modular Reactors (SMRs) Combined with Value Add Mining.

Australia has for many years dug and shipped ore for a pittance of the true value of the materials in question.

The inefficiency of bulk raw material transportation and the massive overhead costs, both in dollars, and global warming, impact ultimately result in a low value add economically and environmentally.

As an example iron ore from central Western Australia is transported via train…

Invent – Wide Area/Volume Ground Current Induced Metal Detector.

Inducing a rotating current using three 120deg offset probes each displaced at 50 to 100 meters radius around the perimeter of a circle allows rotating AC currents.

By rotating at a specific frequency any metal in the current path will subsequently radiate a magnetic field, re Maxwells Equations.

By placing a detection coil and resonant tuned detection electronics within surface area bound by the…

Quantum Gravity Wave Detection within a Equatorial Geostationary Orbital Ref Frame

Space-Time reference plane and subsequent deformation under the influence of mass is well understood.

The detection of elusive (quantum) gravity waves within a space-time reference frame has been successfully undertaken by the LIGO (Laser Interferometer Gravitational Wave Observatory) and jointly with Virgo (Announcement: Sep 27, 2017)

Undertaking this measurement with a space-time reference…

Invent – Solar OV Roof Tile Lighting, Venting and Insect Deterrent.

Terracotta and concrete roof tiles are ubiquitous across Australian houses. The tiles being designed to a standardised form factor that allows each tile to interlock with each other.

Within the roof celling space, below these tiles, it is generally dark, gloomy and often hot and humid

With the advent of relatively cheap solar PV cells a simple invention would be to introduce tiles with built in…

Invent – Cloth Eating Insect Deterrent.

If you’re like me there is alway one favourite jumper that seems to also be the favourite meal of insects when stored away unseen in a dark cupboard.

Inevitably the chemicals used to keep silver fish and moths away from your clothes seem to do nothing but make the smell. With new holes magically appearing!

To counter this ongoing problem a relatively new range of UV LEDs (Ultra Violet Light…

Invent – Vehicle Peltier Effect Lipstick Cooler

Vehicle cigarette (Coffin nail) lighters are ubiquitous in most vehicles.

An option to repurpose these power outlets would be to provide a small 12vdc pluggable Peltier Effect Lipstick cooler designed to plug into the lighter outlet and provide a means of storing and cooling a standard Lipstick within.

Any woman that has left Lipstick within a vehicle has experienced the return to their car on a…

Invent – AC Coupled Solar Panel Photo Voltaic Collector Array

PV cells are typically Inter connected (wired) in series. This typically results in relatively high voltages, particularly under no load. The maximum energy transfer efficiency of PV cells typically occurs in a non linear fashion or more closely in an inverse parabolic fashion. This typically requires inverters to dynamically adjust the load on the cells to maximise energy transfer. The battle…

Invent – Alloy Assay and Metal Detection using Rotating Fields

Nicolas Tesla first detailed the use of rotating fields that ultimately resulted in the ubiquotous use of sychronous motors throught the world. To generate a rotating field one simply requires three (3) alternating sinusiodal waveforms each of which are offset in phase by 120deg. By subsequently alligning these AC sources around the perimeter of a circle at 000deg_120deg_240deg we now are able to…

Where there’s smoke there’s fire. The ability to detect low concentrations of smoke particulates is a non trivial exercise. A common commercial technique is to bring sampled air via a network of pipes to a central LASER based sensor. The operating principal being the measurement of reflected light from smoke particles passing through a light beam. The ability to measure smoke particles in this…
