Funnily enough, we have invested in alternative methods of generating power.
For us, particularly when we're talking about transformational technologies, it really comes from this point of view: do we see an element of the science and the ability of the science to develop and to address a truly fundamental problem for society? As I said, that's one part of the company. It's the ambition to take the resources, which thankfully we have available to us, and focus them on those large-scale problems, knowing that we have the employees that have both the skill sets and the interest in tackling those problems.
Importantly—and it feeds back to our earlier conversation—this also reinforces among our employees and our corporate culture that we're willing to take risks and we're willing to invest in these sorts of moonshots.
