Note their punctuation: up to 9 people, up to 650 miles. I wonder if this is an equivalent of a Tesla: 0-60 in 3.5 seconds, range up to 350 miles.... you can have one or the other, but not both!
Oh, and it's a lot slower than a jet.
It all seems a bit good to be true.
Good point about the punctuation, I hadn't picked up on that. I was dismissing the speed, for shorter journeys, but again I think you have a point as it is a lot slower. Maybe the market will be for night flights when the airports will have (otherwise) shutdown due to noise regs?Mart. Cardiff. 8.72 kWp PV systems (2.12 SSW 4.6 ESE & 2.0 WNW). 20kWh battery storage.

That would only be true if the 'normal' way of producing CO2 was to burn !!!!!! or roast carbonate ores. in fact the usual source of industrial CO2 would be from liquefying & fractionating air - i.e. pretty well equivalent to this (allegedly) 'novel' process.
But you've cut the quote short to exclude such an answer. I gave you an example for displacing FF's for hydrocarbon fuels, such as shipping and air flight where getting away from a concentrated energy source like diesel/kerosene etc is harder.
I'm not trying to say any of these solutions are perfect, just that you seem to be saying that carbon capture isn't CCS, and that's right, it's not, it's just carbon capture.

Slight diversion from energy, as I'm hungry.
Plan to sell 50m meals made from electricity, water and airThe powder known as Solein can be given texture through 3D printing, or added to dishes and food products as an ingredient.
[ Total digression, but this reminded me of a recent 'bored Elon' post where he gives silly solutions, such as 'the ability to upvote / downvote other drivers'. He posted:
1. Buy a 3D printer.
2. Print a 3D printer.
3. Return the 3D printer.]

Electric aircraft, the first fall on the Hype curve
Seems a respectable source, but refers to Airbus' Grazia Vittadini again. So beware of the vested interest. Try reading the comments section, it's a blast!0 -
On the subject of aviation....
This probably won't be news to the more initiated, but using the carbon offset calculator from ClimateCare, a return trip to Australia via Hong Kong for a family of 3 generates 14.1 tonnes of CO2.
To offset that one trip, it'll take that family's plugin hybrid car doing 5,000 miles a year on renewable electricity....... 14 years!
It just kinda brings things into perspective.0 -

Or, somewhat less than 3 years of the energy generated by a domestic solar panel installation of the size that several posters on this forum have. (Assuming all the generated power is actually "saved" in some sense and assuming the Solis webpage is giving me accurate and meaningful figures...)
