The Australian Edition of "PV Magazine" has a couple of good news stories this morning.(AU) https://www.pv-magazine-australia.com/
The first is the announcement of an effective electric motor in the Pratt and Whitney PT6 class
Designed as a CERTIFIED aircraft engine that is able to be retrofitted to existing air-frames or use in (better matched) purpose designs. This promises to reopen many regional air routes,
at least in principle. MagniX powers forward with electric light commercial aircraft plans
Solar PV is boosting regional economies by providing cheaper electricity to off-grid or edge-of-grid communities and industries; soon it could power cheaper electric aviation services. In three years, Gold Coast company MagniX expects to be selling a commercially available certified electric aircraft engine that will reduce the cost of flying light commercial aircraft by between 50% and 80% per operating hour.
Of course rolling out the regional infrastructure
, cheap as will be, will be fraught, with politicians pissing on tyres and incumbents resistance. (natural enough the latter , rankly inevitable the former).
