Elon Musk Wants To Turn CO2 Into Rocket Fuel

SpaceX is embarking on a bold new adventure: making rocket fuel out of thin air. “SpaceX is starting a program to take CO2 out of atmosphere & turn it into rocket fuel,” CEO Elon Musk tweeted on Monday. “Please join if interested.” Such a process — using in-situ resources to generate fuel — could have great implications during our transition to becoming interplanetary, according to Musk.

Will also be important for Mars,” he added in a follow-up tweet.

It’s particularly a pertinent topic for SpaceX’s operations, given that its workhorse Falcon 9 rocket emits plenty of CO2 when it launches. And it’s not quite as far fetched as it sounds. Using a new technique called “direct air capture” (DAC), SpaceX could suck in thousands of tons of carbon dioxide to turn it into a source of fuelBloomberg reports.

Iceland recently started operations at the world’s largest DAC plant, sucking up to 4,400 tons of CO2 a year. The news comes after Musk announced a $100 million prize to come up with carbon removal technologies earlier this year. The goal is to pull 1,000 tons of CO2 out of the atmosphere annually — and eventually scaling up the operation dramatically.

I think this is one of those things that is going to take a while to figure out what the right solution is,” Musk explained back in April. “And especially to figure out what the best economics are for CO2 removal.” “Right now we’ve only got one planet,” Musk said at the time. “Even a 0.1 percent chance of disaster — why run that risk? That’s crazy!”

Iceland is Proof that COVID-19 Vaccines Work

The COVID-19 situation in Iceland is proof that vaccines work, a leading US infectious-disease expert said. Infections are at record highs, but the nation hasn’t recorded a single virus death since May.

Iceland reported 2,847 new infections over the past month, mostly from the highly infectious Delta variant and mostly in fully vaccinated people, official statistics indicated. This is the highest number of new infections in a month since the start of the pandemic, but vaccines appear to be doing their job. The vast majority of new infections are mild at worst.

Of the 1,239 Icelanders who were recorded as having COVID-19 on Sunday, 3% were in the hospital, data showed.

The country hasn’t recorded a single COVID-19 death since May 25, government statistics and Oxford University‘s Our World in Data indicated.

The Number Of Coronavirus Silent Carriers Much Greater Than Previously Thought

Scientists are calling for urgent studies to determine the proportion of people with coronavirus who show no, or delayed, symptoms amid concern that the number of silent carriers may be greater than previously thought.

Iceland, which says it’s tested a higher proportion of inhabitants than any other country, found that about half those who tested positive have no symptoms of Covid-19, Thorolfur Gudnason, the nation’s chief epidemiologist, told BuzzFeed News. As many as a third of the people who test positive show delayed symptoms or none at all, the South China Morning Post reported Sunday, citing classified data from the Chinese government.

The high rate of asymptomatic cases can complicate efforts to stop the spread of the disease because many countries aren’t testing people unless they’re seriously ill. A report by a joint WHO-China mission last month described such infections as “relatively rare” and not appearing to be major drivers of transmission.
