Saturday's annual Bell & Ford vintage clothes garage sale fundraiser for the SHIFT Project was an incredible success with $36,500 being raised at the Byron Surf Club – this year’s effort was up about $7,500 on the last event.

National Reconciliation Week starts tomorrow

National Reconciliation Week (NRW) is a time for all Australians to learn about our shared histories, cultures, and achievements, and to explore how each of us can contribute to achieving reconciliation in Australia.

Local engineer/inventor Sapoty Brook is boldly proposing to push the renewable-energy frontier, with a revolutionary new kind of aircraft he calls a Vaporjet.

On the basis of initial computer simulations, he claims his patented aircraft could hover, and take off and land vertically, and would not have the downward wind experienced under helicopters and quadcopters. 

Brook says, ‘At first sight this appears to go against the laws of physics, but as explained in my video Solar Fuelled Freakin’ Vaporjets, air is drawn (accelerated) down above the craft and dispersed approximately horizontally off the craft’s upper surface. Thus Newton’ First Law is obeyed: momentum is conserved.’ 

He calls the process Vacupulsion, which is powered by fast jets of steam ejected over specially curved surfaces. The vaporjet craft may be able to land in urban areas with little disruption and noise, he says.

Sapoty Brook believes that a solar-fuel revolution is brewing.

‘This process involves using renewable electricity from solar and wind, to split water into hydrogen and oxygen in a surprisingly efficient manner. Hydrogen can then potentially be stored in ammonia. Hydrogen provides lighter and less polluting energy storage than lithium.’

He explains that a recently discovered cheap catalyst is available to split the hydrogen out of ammonia, on demand.

‘The hydrogen can then be burnt eg inside a “vaporjet” to instantly generate steam.’ 

Steam jets

Brook also says that vacupulsion can be used to propel a vaporjet forward, and simultaneously reduce drag, using steam jets at the front of the vaporjet blasting the air, left and right, out of its way over suitably curved surfaces. ‘This way, drag is reduced and the craft is “drawn” forward into a frontal low-pressure zone.’

He says, ‘I think it is premature to take this technology into the arena of venture capital. I want to spend 18 months on computer simulation to refine the design and the underlying theoretical data, without commercial demands. That is my main aim in securing crowdfunding at this point in time. Prototyping should be withheld until the energy efficiency is refined by further simulations.’

Sapoty Brook is launching Vacupulsion Pty Ltd and a global crowdfunding campaign on Wednesday September 27 at the Heart Space, Santos, Mullumbimby from 6pm. All welcome.

Support The Echo

Keeping the community together and the community voice loud and clear is what The Echo is about. More than ever we need your help to keep this voice alive and thriving in the community.

Like all businesses we are struggling to keep food on the table of all our local and hard working journalists, artists, sales, delivery and drudges who keep the news coming out to you both in the newspaper and online. If you can spare a few dollars a week – or maybe more – we would appreciate all the support you are able to give to keep the voice of independent, local journalism alive.


  1. Go Sapoty…have been wondering what you’re up to….sounds as interesting as always….good luck with business launch and future possible production.
