Seb, interesting that in your interview there is no discussion about which technologies are most effective at reducing carbon emissions - it's all about which are most profitable.

That's because none of the technologies Walter Nasdeo talks about are effective. They're scams, invented by greentech entrepreneurs to appeal to green sensibilities, to make the public think we can buy a fix for climate change if only we spend enough money and create enough jobs.

Show me one climatologist or geophysicist - one expert - who believes hydrogen is an answer, who believes solar and wind can replace fossil fuels, who believes all of the "clean energy technologies" he lists, combined, could possibly make a dent in the 37 billion tonnes of fossil fuel CO2 we spew into the atmosphere each year, and I will humbly admit I was wrong. Until then, the decarbonisation horse remains locked in the barn.
