Electric plane manufacturer takes off, receives worldwide orders

[Scott]

 

Australian regional airline Northern Territory Air Service (NTAS) has ordered 20 electric planes from manufacturer Eviation, and they are far from the only customer.

 

 

Looking back only five years ago, the thought of electric commercial planes was laughable. Commercial jets use enormous amounts of energy just to keep them at cruising altitude, and they are often the choice of travel for trips spanning hundreds or thousands of miles.

Green driven technology creates jobs.

 

Again.

I was a sceptic of green technology until living in Bangkok and choking on the fumes from buses and motorcycles. 

 

Electric is the future.

How is that electricity being generated?

There is a huge installed base of fossil fuel power plants. But most of the new power plants coming on line worldwide are solar or wind powered

 

World Adds Record New Renewable Energy Capacity in 2020

Global renewable energy capacity additions in 2020 beat earlier estimates and all previous records despite the economic slowdown that resulted from the COVID-19 pandemic. According to data released today by the International Renewable Energy Agency (IRENA) the world added more than 260 gigawatts (GW) of renewable energy capacity last year, exceeding expansion in 2019 by close to 50 per cent.

IRENA’s annual Renewable Capacity Statistics 2021 shows that renewable energy’s share of all new generating capacity rose considerably for the second year in a row. More than 80 per cent of all new electricity capacity added last year was renewable, with solar and wind accounting for 91 per cent of new renewables.

What "fumes" do Bangkok's LPG-fuelled buses and 4-stroke motorbikes emit that are so much worse than all the other 4-stroke vehicles on the road?

[KhunLA]

"Researchers pinpoint a potential guideline: to keep things sustainable, everyone on Earth should limit their carbon footprint to a grand total of 2.3 metric tons per year.

 

As for a private jet? It emits 2 metric tons of carbon dioxide per hour."

It is a very interesting link but there was one figure missing.

 

That figure is the comparison number between the figure for renewable energy supplies and the existing fossil fuel energy supplies.

 

260 Gw is certainly an impressive figure but compared to what?

 

How much electrical energy is consumed worldwide on a daily basis, compared to an extra 260 gw per day/week/month/year?

[placeholder]

A recent development that could allow for far greater range is the development of a new kind of flow battery. It's capable of holding a far greater charge than other batteries. The developers claim it could be treated like any other liquid fuel. So you just pump the charged liquid into a tank, the same way that fuel is pumped into a fuselage. Unlike fossil fuel though, the liquid doesn't burn up. When its charge is mostly spent, it's drained and recharged, while fully charged fuel is pumped back into the aircraft.

The point is that most new power plants being built are renewable. So over time, as fossil fuel powered plants are retired, the percentage of power provided by renewables will increase. You can't get from here to there with a snap of the fingers.

Looking at the Eviation website, it lists some impressive specifications for the Alise. The plane has a max payload of 2,500 pounds/nine passengers and their luggage, can travel 250 nautical miles (287 miles), and can achieve a max speed of 260 knots (300mph). And while these specs are far from impressive compared to the ocean-crossing jets we have become familiar with at our local airports, the Eviation Alise could be just as capable as other small jets on shorter journeys.

 

It looks like a nice puddle jumper but with only room for 9 pax, a fixed undercarriage (lots of drag) and a relatively short range, there is certainly room to do better.

 

What wasn't mentioned was how long it will take to recharge and the cost of that. Neither was the life of the batteries nor their cost.

 

AFAIR as a comparison a new set of batteries for an electric car are around halt the price of the car. If some one has a better figure I am always happy to learn more.

 

Has there been any way to recycle these batteries yet?

[soi3eddie]

Where is the location map for the airborne charging stations for all these electric planes?

Very interesting but still in the development stage showing promise.

I don't expect to get from here to there with a snap of the fingers.

 

The total world consumption is somewhere in here.

I took a quick skim through it before my brain had an information overload dump. I think that to understand it you will need to have your pc permanently on google search, many hours of research and a lot of cold beers.

Solar  and wind is a joke. We'd all be in the dark if we had to rely on that.

Aircraft are particularly bad for pollution because of the height they travel at.

Thank you for your uninformed opinion. Now for some facts:

Technology will solve all the world's energy problems. A previously unheard of way of energy creation. Perhaps using sound or sea water.

 

And all those plastic bottles floating in the ocean? We had carpets made from them yonks ago. Why not chomp them up and make concrete?

[HappyinNE]

How about in Germany they are tearing out a wind farm to make room for an open pit coal mine.  This wind and solar needs either Nuclear power or continue using natural gas and oil.

As you clearly are not aware, there's a war going on in Europe right now which has straitened supplies. So it's an emergency situation. The more renewable power that gets built, the less likelihood there is of such an emergency occurring in the future.

Not arguing with the numbers, but CO2 is odorless and colorless, that's not what the picture depicts?

An adult human breathes out almost a kilo of CO2 every 24 hours, there's almost 8 billion humans?

There you go, that's the whole problem ... humans breathing ...

... and farting

 

Fart contains; tiny amounts of hydrogen, carbon dioxide, and methane combine with hydrogen sulfide (say: SUHL-fyde) and ammonia.

Is solar solving the world's energy needs? Then there's the problem of recycling all the millions of panels when they reach their shelf life after 25 years.

Not yet ... but it's naïve to think it's not possible.

 

I can only solve my energy problems, now solved.  What are you doing about yours ?  Talking and complaining won't solve anything, try actually doing something.

What are you going to do with those panels when they reach their shelf life? Do you know if and where they can be recycled?

But then comes the infrastructure rebuilding which, if handled correctly, would put the Ukraine at the front of the emerging technology now, but towards the back in the future.
