This Incredible Salmon Cannon is Allowing Fish to Better Coexist with Hydroelectric Dams

Sometimes, something comes along that you see and simply think, “There’s no way that’s a thing.”

I have two words for you: Salmon. Cannon.

It’s real and it’s absolutely incredible.

Comedian John Oliver featured the cannon on this week’s season finale of his HBO show Last Week Tonight, shooting salmon into the faces of a host of celebrities—from Jon Stewart, to Tom Hanks, and even Homer Simpson.

Not only is it admittedly hilarious and wonderful, but it actually has real world benefits that are extremely important. When salmon return from spawning, their swim back upriver can be blocked by hydroelectric dams. This has been a constant problem with hydroelectric energy and there have been various solutions worked out such as gate systems or other control devices to ensure the fish are not affected by the presence of the dams.

The Bellevue, Washington-based Whooshh got the idea from tube transport systems such as London’s Tube and Tesla and Solar City founder Elon Musk’s proposed hyper-fast tube transit line. This style of design is particularly important for fishery operations, as it allows for transport of fresh fish in a rapid manner.

“We believe Whooshh transport products can cost effectively re-invent the way we move certain food sources (particularly when live or fresh) and by doing so, provide a platform for applications and solutions, that will decrease waste, improve yield and quality, and enable use of our natural resources for their most productive uses while being more environmentally friendly,” the company writes. “Apple changed the world when they asked us to ‘Think Different.’ We ask you to ‘Think Again.’ Should you Whooshh? We think so. Should you wait? We think not.”

Drax advances biomass strategy with Pinnacle acquisition

Drax is advancing biomass following Pinnacle acquisition it reported in a trading update

Drax' recently completed acquisition of Pinnacle more than doubles its sustainable biomass production capacity and significantly reduces its cost of production, it reported in a trading update.

The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.

The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).

Drax CEO Will Gardiner said its Q1 performance had been "robust", supported by the sale of Drax Generation Enterprise, which holds four CCGT power stations, to VPI Generation.

This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.

In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.

The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
