Cryonics: Putting Death on Ice

There is a potent thread winding its way through generations of human culture. From Ancient Egyptian rituals to Kurzweil’s Singularity, many paths have sprung up leading to the same elusive destination: immortality.

Today, the concept is as popular as it’s ever been, and technological advances are giving people hope that immortality, or at very least radical life extension, may be within reach. Is modern technology advanced enough to give people a second chance through cryonics?

Today’s infographic, courtesy of Futurism, tackles our growing fascination with putting death on ice.

The Prospect of Immortality

Robert C. W. Ettinger’s seminal work, The Prospect Of Immortality, detailed many of the scientific, moral, and economic implications of cryogenically freezing humans for later reanimation. It was after that book was published in 1962 that the idea of freezing one’s body after death began to take hold.

One of the most pressing questions is, even if we’re able to revive a person who has been cryogenically preserved, will the person’s memories and personality remain intact? Ettinger posits that long-term memory is stored in the brain as a long-lasting structural modification. Basically, those memories will remain, even if the brain’s “power is turned off”.

Descending into the Deep-Freeze

There are three main steps in the cryogenic process:

1) Immediately after a patient dies, the body is cooled with ice packs and transported to the freezing location.

2) Next, blood is drained from the patient’s body and replaced with a cryoprotectant (basically the same antifreeze solution used to transport organs destined for transplant).

3) Finally, once the body arrives at the cryonic preservation facility, the body is cooled to -196ºC (-320.8ºF) over the course of two weeks. Bodies are generally stored upside-down in a tank of liquid nitrogen.

The Economics of Cryopreservation

At prices ranging from about $30,000 to $200,000, cryopreservation may sound like an option reserved for the wealthy, but many people fund the procedure by naming a cryonics company as the primary benefactor of their life insurance policy. Meanwhile, in the event of a death that doesn’t allow for preservation of the body, the money goes to secondary beneficiaries.

Even if we do eventually find a way to reanimate frozen humans, another important consideration is how those people would take care of themselves financially. That’s where a cryonics or personal revival trust comes into play. A twist on a traditional dynastic trust, this arrangement ensures that there are funds to cover costs of the cryopreservation, as well as ensure the grantor would have assets when they’re unthawed. Of course, there are risks involved beyond the slim possibility of reanimation. The legal code in hundreds of years could be vastly different than today.

If you created a trust for specific purposes in 1711, it is unlikely it would function in the same way today.

– Kris Knaplund, Law Professor, Pepperdine University

Cold Humans, Hot Market

At last count, there are already 346 people in the deep freeze, with thousands more on the waiting list. As technology improves, those numbers are sure to continue rising.

Time will tell whether cryonically preserved people are able to cheat death. In the meantime? The cryonics industry is alive and well.

Ranked: The Most Popular Subscription News Websites

While paywalls are becoming increasingly more popular among news websites, most consumers still aren’t willing to pay for their online news.

In fact, a recent survey by the Reuters Institute for the Study of Journalism reveals that only 20% of Americans pay for digital news, and of those that do, the majority subscribe to only one brand.

This begs the question—which news outlets are audiences willing to pay for?

Using data from FIPP and CeleraOne, this graphic looks at the most popular news websites across the globe, based on their total number of paid subscriptions.

*Note: This report relies on publicly available data, and should not be considered an exhaustive list.

The Full Breakdown

With 7.5 million subscriptions, The New York Times (NYT) takes the top spot on the list. 2020 was an exceptionally strong year for the outlet—by Q3 2020, the NYT had generated the same amount of revenue from digital subscriptions as it had for the entire year of 2019.

The Times is the most popular by a landslide—it has over double the number of subscriptions than the second outlet on the list, The Washington Post. Yet, while WaPo is no match for NYT, it still boasts a strong following, with approximately 3 million paid subscriptions as of Q4 2020.

Japanese outlet Nikkei ranks number one among the non-English news websites. It’s the largest business newspaper in Japan, mainly focusing on markets and finance, but also covering politics, sports, and health.

Legacy Papers: Which Websites Come From Traditional Media?

Most of the websites on this list stem from traditional media. Because of this, they’ve had years to establish themselves as trusted sources, and win over loyal readers.

Interestingly, more than half of the outlets included in this ranking are at least 100 years old.

Yet, undeterred by these well-established outlets, a few scrappy websites made the cut despite a shorter history. Four out of the 38 websites are less than 20 years old.

The Athletic is the newest outlet to make the ranking. Established in 2016, the outlet’s target demographic is die-hard sports fans who miss the days of in-depth, quality sports writing.

The Need For Trusted Sources

Amidst the global pandemic, issues involving misinformation and fake news have helped reaffirm the important role that trusted news sources play in the dissemination of public information.

With this in mind, it’ll be interesting to see what the future holds for digital media consumption. With paywalls becoming increasingly more common, will consumers jump on board and eventually be more willing to pay for their news?

Visualizing the Power Consumption of Bitcoin Mining

Bitcoin mining requires significant amounts of energy, but what does this consumption look like when compared to countries and companies?

Visualizing the Power Consumption of Bitcoin Mining

Cryptocurrencies have been some of the most talked-about assets in recent months, with bitcoin and ether prices reaching record highs. These gains were driven by a flurry of announcements, including increased adoption by businesses and institutions.

Lesser known, however, is just how much electricity is required to power the Bitcoin network. To put this into perspective, we’ve used data from the University of Cambridge’s Bitcoin Electricity Consumption Index (CBECI) to compare Bitcoin’s power consumption with a variety of countries and companies.

Why Does Bitcoin Mining Require So Much Power?

When people mine bitcoins, what they’re really doing is updating the ledger of Bitcoin transactions, also known as the blockchain. This requires them to solve numerical puzzles which have a 64-digit hexadecimal solution known as a hash.

Miners may be rewarded with bitcoins, but only if they arrive at the solution before others. It is for this reason that Bitcoin mining facilities—warehouses filled with computers—have been popping up around the world.

These facilities enable miners to scale up their hashrate, also known as the number of hashes produced each second. A higher hashrate requires greater amounts of electricity, and in some cases can even overload local infrastructure.

Putting Bitcoin’s Power Consumption Into Perspective

On March 18, 2021, the annual power consumption of the Bitcoin network was estimated to be 129 terawatt-hours (TWh). Here’s how this number compares to a selection of countries, companies, and more.

NamePopulation Annual Electricity Consumption (TWh)
China1,443M6,543
United States330.2M3,989
All of the world’s data centers-205
State of New York19.3M161
Bitcoin network -129 
Norway5.4M124
Bangladesh165.7M70
Google-12
Facebook-5
Walt Disney World Resort (Florida)-1

If Bitcoin were a country, it would rank 29th out of a theoretical 196, narrowly exceeding Norway’s consumption of 124 TWh. When compared to larger countries like the U.S. (3,989 TWh) and China (6,543 TWh), the cryptocurrency’s energy consumption is relatively light.

For further comparison, the Bitcoin network consumes 1,708% more electricity than Google, but 39% less than all of the world’s data centers—together, these represent over 2 trillion gigabytes of storage.

Where Does This Energy Come From?

In a 2020 report by the University of Cambridge, researchers found that 76% of cryptominers rely on some degree of renewable energy to power their operations. There’s still room for improvement, though, as renewables account for just 39% of cryptomining’s total energy consumption.

Here’s how the share of cryptominers that use each energy type vary across four global regions.

Solar12%13%17%17%
Geothermal8%0%0%6%

Editor’s note: Numbers in each column are not meant to add to 100%

Hydroelectric energy is the most common source globally, and it gets used by at least 60% of cryptominers across all four regions. Other types of clean energy such as wind and solar appear to be less popular.

Coal energy plays a significant role in the Asia-Pacific region, and was the only source to match hydroelectricity in terms of usage. This can be largely attributed to China, which is currently the world’s largest consumer of coal.

Researchers from the University of Cambridge noted that they weren’t surprised by these findings, as the Chinese government’s strategy to ensure energy self-sufficiency has led to an oversupply of both hydroelectric and coal power plants.

Towards a Greener Crypto Future

As cryptocurrencies move further into the mainstream, it’s likely that governments and other regulators will turn their attention to the industry’s carbon footprint. This isn’t necessarily a bad thing, however.

Mike Colyer, CEO of Foundry, a blockchain financing provider, believes that cryptomining can support the global transition to renewable energy. More specifically, he believes that clustering cryptomining facilities near renewable energy projects can mitigate a common issue: an oversupply of electricity.

“It allows for a faster payback on solar projects or wind projects… because they would [otherwise] produce too much energy for the grid in that area”
– Mike Colyer, CEO, Foundry

This type of thinking appears to be taking hold in China as well. In April 2020, Ya’an, a city located in China’s Sichuan province, issued a public guidance encouraging blockchain firms to take advantage of its excess hydroelectricity.
