Nick chats to Tim Washington from JET Charge about using electric vehicles as batteries for our homes.
Vehicle to grid technology could transform not one but *two* trillion dollar industries in energy and transport. All while paving the way to materially reduce carbon emissions and costs.
It is simple enough but does it work? When will consumers have it? What impacts will it have?
And what is it like running a startup with your wife? Thanks to Ellen Liang who also hopped on the mic!

Making Aviation More Sustainable...With Shark Skin (feat. MicroTau)
Season 4 · Episode 1
Monday, June 26, 2023 • Duration 40:45
We speak to Henry Bilinsky from MicroTau. The Sydney-based startup’s shark skin technology applied to planes has the potential to improve the efficiency of aviation by up to 10%, meanwhile saving airlines up to $61 billion a year on fuel.
In Australia we love flying and given our vast and isolated land, we often NEED to fly. While there are a number of options to get to zero carbon transport, many of these solutions may take decades for mass adoption. This includes technologies like battery or hydrogen powered planes (which we covered on our episode with AMSL Aero) or even sustainable aviation fuel.
But in the meantime, we have to pursue anything and everything that can increase the efficiency of aviation. This is where MicroTau’s shark-skin comes in.
In this episode we cover:
The challenges of decarbonising long haul transport;
How Henry came up with the idea;
How the US Airforce got involved with the idea;
Sharks on a plane you say? How does this actually work; and
