Can flow around a trapezoid make for a more efficient beam?

Looking at this flow diagram in Autodesk app Force Effect Flow I wondered if the rough trapezoid I drew creates a situation where it could magnify or modify a beam (just based on the path of the smoke).

How would it be different in 3D?


Could you widen/narrow/modify the trapezoid to focus the beam?





Audiobus interface into new Evernote app – Snippnriff

Snippnriff– musical snippets and riffs remembered

Problem being solved

In a session of iPad music app experimentation there are frequently short snippets of music or interesting riffs to be captured quickly for later retrieval. Rather than cumbersomely storing them in each individual app they can all be sampled descriptively in Evernote Snippnriff.


Connect Evernote Snippnriff as an Audiobus output device to capture snippets of music and riffs that naturally materialise when playing with iPad musical apps.

When activated, a Snippnriff capture will record the sound sample, identify the applications using the Audiobus API, optionally capture MIDI, optionally capture timing settings and then store the sample in an Evernote Snippnriff notebook.

The note will be automatically tagged with each device used. Other information such as timing and MIDI can be specified in autotag settings.

Later versions (which may need to be done in conjunction with Audiobus) will allow you to retrieve the Snippnriff note and feed this back into Audiobus to allow it to automatically set up the devices in the configuration that was present when the capture was done.

(note this idea has also been submitted for developers to consider in the Evernote Devcup 2013 )


Sphere Light


Please the machine – iPhone or Android app

This application is based on the concept of “pleasing” an artificial intelligence or a user driven algorithm that “judges” your artwork, photograph, animation, music or writing and tells you if it is pleased with it.

The point is that it gives a restrictive environment which enhances creativity (in the same way that photographers will sometimes restrict themselves to only shooting objects of a certain size, shape or colour).

Each algorithm/AI will have it’s own blog/site/section/subreddit that displays artistic endevours that meet it’s criteria only. While you can choose to make your interaction with the algorithm private, if you make it public then anyone can contribute.

If you are the original creator/submitter of the algorithm (and the site is set up to enable this function) then you will share in any site generated revenue.

Retrofit existing hydraulics with artificial muscles

Be prepared for when artificial muscles suddenly become available as packages/units that contract and effectively expand. Know how to retrofit these to existing machinery and control them with the existing hydraulic controls so that you can take advantage of servicing the upgrade market.


One way to farm fish in the ocean

Firstly I don’t have to own the ocean, just enough of it to raise the fish that I have bred or selected as needing only a few hundred cubic kilometres of space. One of the traits I have bred into them is a discomfort of being around frequency x and an attraction to frequency y (in the mature, edible stage). Using a 3D printer and basic electronics I construct lengths of frequency x emitters that I anchor to the ocean floor and this serves as my electronic fence. I use the same technique to create the equivalent of a cattle pen of frequency y strands that I activate when I need to harvest. The fish would come to me.

An increased Australian population – 50 million by 2040

I would like to see Australia at 50 million plus by 2040. I believe the ultimate economic success of this geographical location depends on increased population.

We can always point at problems and reasons why this can’t be done yet this implies that we can’t get smarter and that our children won’t be better problem solvers than us. History tells me that this problem solving evolution will continue, regardless of the fears of current generations.

– Not enough water? Build a power source such as a nuclear plant or solar farm to desalinate sea water and use the extracted salt for some new product or process (eg heat liquefy it with daytime solar for nighttime use). 3d printing technology may be able to do something amazing with salt. With some hitherto unknown modification, salt may turn out to be a great road paving material.

– Not enough infrastructure? Let people and businesses innovate without government interference. Imagine what you could do without the vehicle, road and construction regulations. For example – a town with only off-road segways where people live in retrofitted shipping containers and supplied by 4wd road trains with 12 trailers. One of the trailers could be full of batteries to power the truck which in turn could be charged by the town’s geothermal power (which may have been the original reason for why its location was selected). The truck may need to stop along the way to exchange its trailer for a freshly charged one but this could then encourage further development between towns.

– Not enough food? Vertical farming is still in its infancy. Hydroponics and greenhouses accomplish food growth in unusual areas. Imagine if the government and fearful people got out of the way and you could grow hemp crops for oil and fibre. Imagine if the intellectual property laws were non existent so that genetically modified hemp or other food crops could be watered with salty water. The stubble/hay left after harvesting may become a product needed by a town on the coast who used it to feed the fish they were farming. The fish are manageably contained in a vast expanse of ocean using a device that was harnesses phosphorescent bacteria to make a fish fence.
