Anders Forslund, co-founder and CEO of Heart Aerospace, has a problem.

How do you build a commercial airplane that can fly on battery power -- and win the approval of regulators around the world?

As other sectors are decarbonizing, emissions from aviation are projected to triple by 2050. This is partly because figuring out how to build a plane that doesn't burn jet fuel is a very hard problem that Anders has been trying to solve for years.

But that marks just one step on a long, uncertain road to clean fusion energy.

“If what has been reported is true and more energy has been released than was used to produce the plasma, that is a true breakthrough moment which is tremendously exciting".

“It proves that the long sought-after goal, the ‘holy grail’ of , can indeed be achieved.”

But experts have stressed that while the results would be an important proof of principle, the is a long way from being a mainstay of the energy landscape.

Maar ik onthoud momenteel toch (vooral):

"drop in the ocean",
"not commercially viable",
"not the silver bullet",
"no sustainable business model",
"not taken off",
"prototype",
"scale model",
"too costly to produce",
"lab",
"in theory",
"hasn't been built yet",
"the economics just don't work",
"targets come and go",
"targets not met",
"progress has been slow",
"still years away",
"scaling up complicated",
"existent network not suitable",
"logistic headache",
"growing pains"

"[...] Kan het bijvoorbeeld ook gebeuren dat de ozonlaag een beetje wordt afgebroken [...] door de reactie met andere chemische stofjes in de atmosfeer?"

“Er is veel meer onderzoek nodig om te kijken: hoe moet dat eigenlijk, aerosolen op een gecontroleerde manier in de lucht brengen? En wat is de impact daarvan? Heeft het de afkoeling die we verwachten, maar ook wat is de consequentie van je afkoeling? Is het middel niet erger dan de kwaal?"
