Technologies That Are Most Likely To Keep Planet Earth Clean

It is not a secret that humans are evolving. However, tough technology improves significantly during the past decade; humanity will have to crank it up a notch and embrace the technology that can keep our world safe. Since we don't have a reserve plant, we can move to.


The planet is in jeopardy. Humans are both causing and contending with deforestation, ocean acidification, and climbing temperatures, to name a few of our less-than-benign legacies.

The facts are complex, but the trends aren't easily disputed. And yet, the topic of global peril is an ire-raising one these days, liable as not to put a reader into a defensive crouch. Perhaps it's because we're thrummed over the head with the worst of it all and rarely allowed to revel in solutions.

Less controversial, therefore, maybe the idea that technology has a role to play in making our planet a more comfortable and sustainable place for humans to continue plodding along. Living up to the lofty title with a definitive list of 10 technologies that will help our planet survive is probably a losing proposition. You're likely not to take issue with some aspect of this list. That's OK. It's what the comments section is for; I'd love to hear from you.

It's also worth noting that some of these technologies come with risks of their own. Our number one best bet to help our planet could even spell doom for our species.

But, as I look at the threat landscape, as well as the tools under development to help, some optimism can't help but creep in. Here are my picks for ten technologies most likely to help save the Earth.


1. SOLAR GLASS


What if every window in a skyscraper could generate energy? That's the promise of solar glass, an emerging technology that's getting a lot of buzz in design and sustainability circles. Like it sounds, solar glass is suitably transparent window material and captures the sun's energy and converts it into electricity.

The big hurdle has been efficiency. High-performance solar cells can achieve 25% efficiency or more extraordinary, but maintaining transparency means sacrificing the efficiency with which light is converted into electricity. But a University of Michigan team is developing a solar glass product that offers 15% efficiency and climbing while letting a full 50% of light pass through. According to projections from nearby Michigan State, 5 to 7 billion square meters of usable window space exists, enough to power a full 40% of U.S. energy needs with a solar glass product.



2. GRAPHENE


More robust than steel, thinner than paper, more conductive than copper, graphene is truly a miracle material—and until recently, an entirely theoretical one. Graphene is an ultra-thin layer of graphite that was first discovered in 2004 at the University of Manchester. It is now the subject of intense research and speculation. Many predicted it would be next in line after bronze, iron, steel, and silicon in promulgating our species' cultural and technological evolution.

A mere one-atom thick, graphene is flexible, transparent, and highly conductive, making it suitable to a massive range of planet-healing applications. These include water filtration, superconductors capable of transferring energy across vast distances with minimal loss, and photovoltaic uses, to name a few. By vastly increasing efficiencies over current materials, graphene may prove to be a cornerstone of our green rebirth.

3. PLANT-BASED PLASTIC


We have to put an end to single-use plastics. Initiatives are already underway across the U.S. to ban or severely limit their use. I live plastic straws only given out upon request in L.A., and single-use plastic bags have disappeared from grocery stores. But the problem is deep-rooted and deeply ingrained in our consumption economy. I live near the ocean, and the quantity of plastic debris visible on an average day is devastating.

Plant-based plastics that biodegrade are one palatable solution, as they could, in theory, replace many of the plastic products already in circulation. An Indonesian company called Avani Eco has been making bio-plastic out of cassava since 2014. Like fake meat and solar glass, this should become a booming sector in the years ahead. But beware: Not all bioplastics biodegrade, and the merit of some production techniques is debated. Part of becoming a responsible consumer in the next decade will know the life cycle of the products we choose to buy, from creation to entropy.

4. FAKE MEAT


Dear carnivores, I have good news and bad news. First, the bad: Meat production is absolutely atrocious for the planet. In 2017, more than 15,000 world scientists signed a Warning to Humanity calling for, among other things, drastically diminishing our per capita consumption of meat. One issue is land use. The production of beef relies on 164 square meters of grazing land per 100 grams of meat. It is one of the significant causes of deforestation in Central and South America, leading to unprecedented carbon release into the atmosphere. The Food and Agriculture Organization believes livestock accounts for about 14.5% of anthropogenic greenhouse gas emissions. Animals also use vast amounts of freshwater while the contaminated runoff from industrial livestock operations pollutes local waterways.

The good news? Fake meat is finally good. Companies like Beyond Meat and Impossible Foods are delivering delicious alternatives to meat that stand as pretty decent substitutes for the real thing. As much as technological achievement and advanced food science, these companies' real triumph is that they've made fake meat culturally hip. You can now order meatless burgers at Burger King and get a meat-free taco at Del Taco.



5. BATTERIES


Power is the limiting factor holding back a lot of green technologies. Wind and solar, for example, can generate vast amounts of electricity, but a significant shortcoming has throttled adoption of the technologies: Sometimes, it isn't windy or sunny. Electric cars, similarly, are making huge strides, but until range increases and charging times diminish, fossil fuels are going to rule.

Existing battery technology won't cut it. For one thing, it's too expensive. According to the Clean Air Task Force, for California to meet ambitious goals of powering itself through renewables only, the state would need to spend $360 billion on energy storage systems. One company called Form Energy is developing what are known as aqueous sulfur-flow batteries that will cost somewhere between $1 to $10 per kilowatt-hour, compared with lithium's $200 per kilowatt-hour cost. Storage times should increase, too, perhaps lasting months. Form's solution could help California meet its energy targets before the middle of the century, providing a roadmap for the rest of the world.

6. ENVIRONMENTAL SENSORS


To heal the planet, we need to measure it. Distributed sensors are one of the unsung technologies allowing that to happen. The networked sensor environment's continued spread will be one of the undergirding technologies behind nearly every sustainability effort imaginable.

Want an example? Back in the 1980s, taller smokestacks helped reduce local air pollution on the east coast. The problem was that the smokestacks were correlated to a higher rate of acid rain, leading to vast deforestation. How was the connection drawn? First networked pollution sensors.

The technology, of course, has advanced since then. Networked sensors as small as a dime are already monitoring air and water quality, identifying pollutants, tracking acidification, and capturing real-time data on phenomena that are crucial to our social and economic wellbeing. Wearable air quality sensors are on their way, and localized sensor networks monitoring energy and water usage in buildings are cutting down on waste. The further proliferation of these sensors will dramatically impact the way we live.



7. SMART GRIDS



The way our power infrastructure -- collectively known as the grid -- works now is a troubling holdover from the 19th and 20th centuries. Power production is still mostly centralized and distributed downstream, eventually reaching end users. The problem is that these grids are highly sensitive to fluctuations in usage and output. To make them work reliably, they demand an overproduction of energy. They're prone to attack, and they tend to rely on pollution-emitting energy sources.

Smart grids are already being rolled out in testbeds in the U.S. and internationally. The concept isn't so much a single technology as the deployment of considerable energy, distribution, networking, automation, and sensing technologies to design a new grid for the 21st century. Smart grids will enable local production of power down to the household level, fed back into the grid upstream. Sensing technology and more accurate prediction models will fine-tune energy production to avoid overproduction. Better battery technology (see #7 on this list) will enable the storage of renewably sourced energy. The concept even reaches beyond the light socket. As appliances get smarter, the grid may automatically signal them to shut off to conserve power. All of this could add up to a massive change in how our power infrastructure functions. According to a study by the Electric Power Research Institute, by 2030, Smart Grid technologies might help us reduce carbon emissions by 58% compared to levels from ten years ago.



8. CARBON CAPTURE


There's too much carbon dioxide in the air, and it's warming our planet. What if we could capture and sequester it?

That's the premise of Carbon Capture and Storage (CCS), an emerging class of technologies that are primed to play an essential role in the health of our planet in the decades ahead. According to the CCS Association, capture technologies allow the separation of carbon dioxide from gases produced in electricity generation and industrial processes by one of three methods: pre-combustion capture, post-combustion capture, and oxyfuel com­bustion. The carbon is transported by pipeline and stored in rock formations far below ground.

In 2017, the world's first CO2 capture plant went live in Switzerland. Startups in the U.S. and Canada have developed carbon capture plants of their own. At scale, the technology could help reverse one of the most alarming environmental trends of our time.

9. NUCLEAR FUSION


Our sun is powered by the fusion of hydrogen nuclei, forming helium. For decades, scientists have been working on harnessing the same process to create sustainable terrestrial power. The effort is exceptionally compelling from an ecological standpoint because it represents a zero-carbon emissions form of energy. Unlike nuclear fission, the process that powers current nuclear plants, fusion does not result in long-lived radioactive nuclear waste production.

The problem is heat. To generate net positive energy when two particles fuse, the reaction has to take place at millions of degrees celsius, and that means whatever vessel you're using to do the fusing will, well, melt. The answer is to suspend the reaction in a floating plasma, so the extreme heat doesn't touch the chamber, a process researchers believe can be achieved using high-powered magnets. The typical timeline offered for fusion power is 30 years, but a team at MIT working with a new class of magnets believes it can get fusion power into the grid in just 15 years, which would be a massive boom in the fight to slow the planet's warming trend.

10. ARTIFICIAL INTELLIGENCE


Sure, it may doom us all via many sci-fi premises (nuclear annihilation, strategic species eradication, the rise of the robots). Still, artificial intelligence also might be our best bet computing ourselves out of the grave state we find ourselves in.

Microsoft's A.I. for Earth program is one effort underway to harness A.I.'s potential for the planet's good. The program has given more than 200 research grants to teams applying A.I. technologies to planetary health in one of four areas: biodiversity, climate, water, and agriculture. Primitive A.I. and machine learning algorithms are currently analyzing icy surfaces to measure changes over time, helping researchers plant new forests with precise layouts to maximize carbon sequestration, and enabling warning systems to help stem destructive algae blooms.

A.I. impacts agricultural practices and will soon transform how farming is done in industrialized nations, reducing our reliance on pesticides and drastically lowering water consumption. A.I. will make autonomous vehicles more navigate more efficiently, lowering air pollution. A.I. is being deployed by material scientists to develop biodegradable replacements to plastics and develop strategies to clean our oceans, which receive some eight million metric tons of plastics annually.

Fundamentally, A.I. will be the bedrock of our future efforts to undo the damage already done to the planet while figuring out scalable solutions to sustaining our species' energy, food, and water needs.
