Protein created out of Air and electricity.... yes, we have that now.

No, it's not a joke. Scientists have invented a way to create single cell protein from carbon dioxide and electricity.

Thoughts on where this takes us?
The powder...

TAKE one serve of carbon dioxide. Apply high voltage. Wait a few weeks ... and enjoy a meal of single-cell protein. It may not be a culinary delight, but it could feed our future.

But it may soon be reducing the strain on our crops by providing an alternative source of fodder for animal feeds.
Ultimately, protein ‘reactors’ have the potential to create the building blocks of meals aboard long-duration space flights and as a rapid-response counters to famine.
“In the long term, protein created with electricity is meant to be used in cooking and products as it is,” says Juha-Pekka Pitkänen, principal scientist at VTT. “The mixture is very nutritious, with more than 50 per cent protein and 25 per cent carbohydrates. The rest is fats and nucleic acids.”

Is the protein a Republican or a Democrat?

Two weeks? But I'm hungry now.

How much power is needed to make a single meal?

Not sure. I know my post work out shake has 1 scope and it's 20 grams of protein...

I want to say they used solar.
Posted on 7/30/17 at 10:48 pm to MButterfly
I'm sure they probably didn't.
But it is probably compatible with a transformer fed by a panel though. This is only to prove the concept.
Solar based grid independence comes later.

I'm more interested to hear what diazotroph they used.
Edit:
Not one at all. They have to be using electricity to make high voltage sparks in an pressurized, somewhat high CO2 environment with water cultured with nitrobactor that the atmosphere bubbles through.
The food is the dried up cells.

Reminds me of the Miller experiments done in the 50's in an attempt to create life in a lab. Miller put various gases and water in a test tube and then electrified them to simulate lightning. His goal was to mimic the conditions of early life. He didn't create life, but he did generate amino acids.

Proteins also contain nitrogen, hydrogen and stinking sulfur. Where do these come from in the air/electricity method?

They are using high voltage in air to generate tribonded diatomic nitrogen free radical that reacts with oxygen to generate nitric oxide.
The nitric oxide in the atmosphere is then bubbled into aqueous solution containing essential trace materials and buffer (of which sulfur is one), reacting with the water to generate nitrous acid, the conjugate base of which is nitrite.
Nitrobactor in the solution uses the nitrite as an nitrogen source, converts to nitrate, and uses the energy from the process to fix the carbon from carbon dioxide as well as general catabolism to sustain and replicate the cell.
The cultured soup is then dessicated and served as food.

Where does the sulfur come from? Sulfur-containing amino acids, methionine, cysteine and taurine are essential nutrients. Sure you can synthesize a "protein" without sulfur but it's of poor quality.

Did you miss the part where I said it was added?
As well as iron, phosphorus, magnesium, and a few more elements.
Basically the aqueous solution is a minimal nutrient broth minus a carbon source as optimized to the nitrobactor species used. We are talking mg/mL quantities, if not even lower.
ETA: taurine also isn't an amino acid in the biochemical sense, is not an essential nutrient, and wouldn't be produced in this circumstance.

kooks have said replicator technology has been around for decades.
Pure, clean food just a button a way.

Does this have any implications regarding the origin of life on earth?
