Over recent periods National has run a very tightly focused campaign against state support for Tesla owners. But news that Christopher Luxon actively sought a Government supplied Tesla when he already owns one suggests that he thinks that the rules should be different for him.

Researchers have published a study revealing their successful approach to designing much quieter propellers.
The Australian research team used machine learning to design their propellers, then 3D printed several of the most promising prototypes for experimental acoustic testing at the Commonwealth Scientific and Industrial Research Organisation s specialised echo-free chamber.
Results now published in
Aerospace Research Central show the prototypes made around 15dB less noise than commercially available propellers, validating the team s design methodology.
RMIT University aerospace engineer and lead researcher Dr Abdulghani Mohamed said the impressive results were enabled by two key innovations - the numerical algorithms developed to design the propellers and their consideration of how noise is perceived in the human ear - as part of the testing.

AAUS is once again proud to be hosting an Industry Awards night to recognise individuals and organisations that have made a significant contribution to the Australian unmanned systems industry.
This year, over 80 nominations were received for the 5 award categories highlighting the strength of our rapidly developing industry. Of interest was that over a quarter of these were nominated for the Innovation Award.
All nominations were high quality and consisted of an impressive list of individuals and organisations. Our judging panel had the difficult job of selecting finalists for each category.
Finalists are listed below.
Winners will be announced during the AAUS Gala Dinner that will be held in Canberra on the evening of Wednesday March 10, 2021. The Gala Dinner is being held in conjunction with the AAUS RPAS in Australian Skies 2021 conference. Tickets for the Gala Dinner can be purchased via the conference website.
