Scientists Create Water-Harvesting Technology That Uses Kitchen Scraps and Seashells

Researchers at the University of Texas at Austin have figured out how to turn everyday throwaways into a technology that pulls clean water straight from the atmosphere.
The team used different organic materials to develop “molecularly functionalized biomass hydrogels” that extract drinkable water from air using only mild heat, producing nearly four gallons daily per kilogram of material—about three times more than typical water-harvesting technologies.
“This opens up an entirely new way to think about sustainable water collection, marking a big step towards practical water harvesting systems for households and small community scale,” said Professor Guihua Yu, who led the research team.
The research is relevant today, considering nearly 4.4 billion people have restricted access to safe drinking water, according to recent studies. That’s nearly 50% of the entire human population.
Extracting water out of air is not really new, but what sets this approach apart is its use of natural materials that would otherwise end up in landfills—making it safer and more environmentally friendly too. The researchers successfully converted cellulose (found in plants), starch (from foods like corn and potatoes), and chitosan (from seashells) into high-performance water harvesters.
“At the end of the day, clean water access should be simple, sustainable, and scalable,” said Weixin Guan, another researcher involved in the study. “This material gives us a way to tap into nature’s most abundant resources and make water from air—anytime, anywhere.”
The technology works through a two-step process. First, researchers attach thermoresponsive groups to make the materials sensitive to temperature changes. Then, they add special molecules called “zwitterionic groups” to boost the biomass’ water absorption capacity.

The result is a hydrogel that works somewhat like the silica gel packets found in a normal dehumidifier, but with dramatically better performance and safer composition, using natural materials instead of synthetics.
During field tests, the system demonstrated to be successful—a single kilogram of material produced up to 14.19 liters of water daily. The team says similar technologies typically generate between 1 and 5 liters per kilogram each day.
Unlike conventional water harvesting systems that often rely on energy-hungry refrigeration to condense atmospheric moisture, these hydrogels need only mild heating to 60°C (140°F) to release their captured water—a temperature achievable with simple solar heating or waste heat from other processes.
This minimal energy requirement makes the technology particularly promising for off-grid communities and emergency situations where power might be unavailable.
Professor Yu’s team has been developing water-generating technologies for years, including systems adapted for extremely dry conditions and injectable water filtration systems. They’re now working on scaling production and designing practical devices for commercialization, including portable water harvesters, self-sustaining irrigation systems, and emergency drinking water devices.

Filmmakers Bet on Web3 to Fix Hollywood Film Financing

Cutter Hodierne knew the odds were against him. As an independent filmmaker trying to secure funding for “Cold Wallet,” a crypto thriller about a heist gone wrong, he faced the usual hurdles—hesitant investors, an unpredictable industry, and a financing system that favored big studios over fresh voices.
“In Hollywood’s centralized model, breaking in is difficult,” he said. “You never know if you met the right person, if your script was overlooked, or if your work is truly considered.”
So instead of taking the traditional route, he turned to the decentralized film industry. Often referred to as Film3, it leverages blockchain technology, community voting, and cryptocurrency to fund movies, and television series. Unlike the traditional Hollywood system, which relies on centralized studios, agents, and intermediaries, Film3 lets filmmakers connect directly with their audiences and financing.
Hodierne put 10 minutes of his film up on the Decentralized Pictures website for review, where a community of producers, writers, investors, and film buffs got a look at his sizzle reel. In exchange for reviewing the clip, they earned $FILM, Decentralized Pictures’ token, which the studio says is “fuel for the platform. Users can stake them on their favorite projects, use them to pay others to review their own submissions (as a rewards pool), or simply purchase entry vouchers to pay for application fees for various creative financing rewards.”
One reviewer in particular was especially struck by the clip: “Steven Soderbergh, the king of the heist genre, gave us his blessing,” said Hodierne.
Soderbergh invested in the film, and Decentralized Pictures followed on with a grant, giving “Cold Wallet” enough money to make Hodierne’s movie. Now screening as a “Steven Soderbergh Presents” project, the movie is at select theaters and available for rent or purchase on Apple and Amazon Prime Video, and has garnered respectable reviews.
“Hopefully, it connects with viewers,” Hodierne said. “What excites me most is that you can rent and buy it on-chain with crypto—it’s highly appropriate.”
It’s another big step in the journey of the dominant studios in the Film3 movement, Decentralized Pictures and Gala Films, which have more than 60 movies and TV series in the works.
“We’re building the studio of the future,” said Decentralized Pictures co-founder Roman Coppola, a member of the Coppola filmmaking family. “At our company, American Zoetrope, and in my dad’s work, we value community and a cafe culture where people come together, share ideas, and compare notes.”
Coppola and others pointed out that just as important as community participation is the decentralized funding model that can support filmmakers, particularly those with distinctive voices and meaningful stories to tell, by allowing them to bypass industry hierarchies.
“The term we’ve been using—DeFiFi, decentralized film finance—represents a shift in film funding,” Stacy Spikes, co-founder of movie subscription platform MoviePass said during an interview with Decrypt at ETH Denver. “Distribution companies will still be needed to push films into the marketplace, but until now, back-end participation wasn’t possible. With smart contracts, it is.”
The idea is already gaining traction. In 2024, Film3 made history when actress Mena Suvari earned a Primetime Emmy nomination for her role in “RZR,” a sci-fi series created by David Bianchi’s Exertion3 Films in collaboration with the blockchain-powered streaming platform Gala Film.
Spikes likened the potential of decentralized filmmaking to past independent and genre film movements.
“If you go with the community—particularly black and brown communities or genre films—Web3 is a great place to tap into,” Spikes said. “I feel that people who were hesitant to invest will now be more likely to do so because they know they’ll get their money back.”
Hodierne also noted that by eliminating distributors and sales agents, all proceeds go directly to the filmmakers and Decentralized Pictures, allowing them to reinvest in independent artists and future projects.
“As a filmmaker, I’ve seen how centralized and fickle the industry is. This shift is a big deal, especially as streaming platforms pay artists less while struggling themselves,” he said. “It’s an exciting convergence for films, and for ‘Cold Wallet,’ a crypto thriller, this feels like the perfect first step in opening that door.”

Disclosure: The views and opinions expressed here belong solely to the author and do not represent the views and opinions of crypto.news’ editorial.
One of the most intriguing aspects of crypto is its sense of anonymity. Bitcoin (BTC), for example, was created in 2008 by an unknown figure using the pseudonym Satoshi Nakamoto, and to this day, the true identity of its inventor remains unknown. The veil of anonymity has allowed users to create distinct identities through wallet addresses, adding an extra layer of privacy and discretion to transactions.
This concept of openness and universal access is one of the core promises of digital currencies, allowing anyone with internet access to engage, regardless of their financial history or background. However, even though the ethos of crypto promotes inclusivity, the reality hasn’t always reflected this.
The early days of crypto were defined by the archetype “crypto bros,” referring to a specific demographic of young, tech-savvy men who influenced the industry’s direction. Their influence extended to the design of projects, development of key protocols, and framing of the culture surrounding digital assets.
However, as the industry matured and evolved, efforts were made to reflect and include more female voices. This shift helped address the imbalance between gender representation, bringing new perspectives into the industry.
A 2024 study revealed that over 560 million cryptocurrency owners exist globally, with 61 percent identifying as male and 39 percent as female. This marks an increase from the previous year, when the global total was 420 million, with 37 percent of owners being female, signaling a positive shift.

In response to this trend, organizations have emerged to address crypto’s gender imbalances. Conferences and events once primarily targeted toward the male-dominated demographic have changed to allow women to step into the space and take the lead.
The Association for Women in Cryptocurrency, or AWC, for example, was founded in 2022 as a platform for women looking to enhance their knowledge and education in crypto. Led by Amanda Wick, AWC hosts various events, like webinars and in-person meetups, where women can learn from industry experts and connect with mentors who can guide them and help them discover new career opportunities.
Recently, Binance shared that it will offer global programs exclusively for women through its Binance Academy platform in honor of International Women’s Day. The events will be held across five continents at 11 venues to help women ease their way into the industry.
While women have made significant strides in the DeFi space, now accounting for 40 percent of Binance’s workforce, leadership positions have been predominantly held by men. Despite this, several women have established themselves as leaders in the space.
Perianne Boring, for instance, is the founder and CEO of the blockchain advocacy group The Digital Chamber, working alongside Congress and the government to promote and regulate blockchain technology. Her leadership role has made her an advocate for adopting blockchain technologies, as she has become a well-known voice in the space discussing the future of finance. In December, President Trump also considered Boring as a potential CFTC chair.
Another established female leader in the space is Joanna Liang, the founding partner of Jsquare, a tech-focused investment firm specializing in blockchain and web3. With a previous background as CIO at Digital Finance Group (DFG), a global Venture Capital firm focusing on crypto projects, Liang recently launched Jsquare’s latest fund, the Pioneer Fund. The fund has successfully raised $50 million in capital, making its first investment in the startup MinionLabs. The fund will focus on emerging technologies in the crypto space, including PayFi, real-world assets (RWAs), and consumer apps.
Laura Shin is also a prominent name in crypto and is recognized as one of the first mainstream media reporters to cover cryptocurrency full-time. She is the author of the book, ‘The Cryptopians: Idealism, Greed, Lies, and the Making of the First Big Cryptocurrency Craze,’ and the host of the podcast Unchained. Laura has shared her expertise at events such as TEDx San Francisco and the International Monetary Fund.
Over the past 16 years, women have been instrumental in helping legitimize crypto assets throughout the financial landscape. Their contributions have spanned various sectors in the ecosystem, helping shift the narrative around crypto from a niche, speculative asset to a more widely recognized and accepted financial tool.

Solana May Soon Get a Major Change—Here’s Why Builders Are Butting Heads Over SIMD-0228
Published

A new Solana proposal aims to change the frequency at which new tokens are generated on the prominent blockchain—and the suggested changes are generating serious debate ahead of the imminent vote.
The proposal, also known as SIMD-0228, looks to move from fixed-rate token emissions to a programmatic, “market-based emission” schedule that is based on staking participation rate.
In other words, instead of decreasing Solana inflation based on a fixed, time-based schedule, SIMD-0228 proposes that Solana inflation dynamically changes based on network activity.
“The [current] mechanism is not aware of network activity, nor does it incorporate that to determine the emission rate. Simply put, it’s ‘dumb emissions,’” reads the proposal. “Given Solana’s thriving economic activity, it makes sense to evolve the network’s monetary policy with ‘smart emissions.’”
The proposal’s authors—Multicoin Capital’s Tushar Jain and Vishal Kankani, and Max Resnick, lead economist at Solana-focused R&D firm Anza—believe that so-called smart emissions would benefit the network and stakers by reducing inflation, spurring DeFi usage, reducing sell pressure, and improving the narrative around its existing inflation.
Notable Solana builders and personalities, including Solana Labs co-founder Anatoly Yakovenko, have signaled support for the proposal as well.
“The counter arguments to 228 are pretty bad because the cost of inflation is something on the order of […] $1-2 billion per year,” Yakovenko posted on X (formerly Twitter).
The counter arguments to 228 are pretty bad because the cost of inflation is something on the order of (global average income tax rate * inflation). Or $1-$2 BILLION per year.
1) small validators will lose out
Yes. That’s probably going to happen. It doesn’t cost $1 BILLION…

Helius Labs CEO Mert Mumtaz added that the “strongest argument for 228 is that it incentivizes and speeds up the timeline towards a network centered on real economic value.” That line of thinking was echoed by Placeholder VC partner Chris Burniske as well.
“I’m in favor of SIMD-228,” Burniske said on X. “In the long run, real yield comes from what the demand-side leaks to the supply-side, and inflation is just a bootstrapping mechanism to get to that place.”
But not all of the Solana community is ready to accept the proposal, which has been modified in the last two months based on feedback. As the proposal inches closer to a vote, some builders have taken aim at elements they believe will negatively impact the ecosystem.
One such dissenting opinion comes from SolBlaze.org, a Solana network validator that will have the option to vote on the proposal.
SIMD-0228 aims to add a dynamic element to staking rewards issuance with the goal of lowering inflation, citing alternate mechanisms such as MEV rewards which can compensate for decreased inflationary rewards. Sounds good in theory? Let me explain why it’s a terrible idea.

The validator added that the goal of lowering inflation “sounds good in theory,” but is a “terrible idea,” citing that SIMD-0228 will “drastically decrease” the amount of Solana tokens staked. Given that view, they believe it will threaten decentralization and the security of the network while impacting Solana’s DeFi protocols, which rely on staking rewards.
“DeFi is what powers Solana adoption, and regular users should care about that if they want Solana to succeed,” a SolBlaze representative told Decrypt when asked why the average Solana participant should care about SIMD-0228.
Others, including Solana Foundation President Lily Liu, have spoken out against the proposal.
“[SIMD-0228] is too, too half-baked,” posted Liu. She signaled support for fixed rates, which she called “not dumb and arbitrary,” citing that predictability is valuable in capital markets.
228 is too, too half-baked
Here’s my TLDR:
1/ Negative impact on SOL the asset during a critical period of growth
Blockchains are networks; they also have a native asset. The network and asset subecosystems are interdependent. Changing network parameters can be good for…
— Lily Liu (@calilyliu) March 6, 2025
“No on the proposal before us,” she said, instead suggesting an extension so the proposal can be adjusted to incorporate other features.
Voting on SIMD-0228 is expected to start Friday evening during Solana Epoch 753, which is estimated to arrive around 8:30pm ET according to timetracking from Solscan. SolBlaze expects a “close vote” and is using the remaining hours to whip up support against the bill.
“Since it needs two-thirds of the vote to pass,” they told Decrypt, “there’s still a chance that enough people can come together to stop the proposal.”
