His ideas, condensed into four installations, are part of the Vauxhall Ampera x Super/Collider Science Weekend, held at The Filling Station, a new venue converted from a petrol station.
At 5.00pm on 17 August, Stevenson–Keating will talk an audience through the concepts, which are as follows:
Solar collectors, designed for the deserts, rooftops and skyscrapers of the future could heat a liquid salt, to yield 24-hour power.
High altitude wind-turbines reaching into the stratosphere to find the energy of global winds like the Gulf Stream and retrieve power.
Biobags – essentially large baloons – floating above landfill sites collecting rising methane which can be stored and used elsewhere.
Algae, which gives off oxygen, can be tanked in cities to provide biofuel and oxygen for city dwellers, while in rural areas this could be produced on a much grander scale.
Vauxhall is promoting its new Ampera electric car at the event, the context being a post petroleum future, and question marks over where our electricity will come from.
The Weekend long event curated by science event organisers Super/Collider, will look at other new scientific developments with hydrogen fuel cell racing and personal rapid transport pods being demonstrated and nightly laser light shows billed.
