Saildrones For Science
Nine years ago, engineer Richard Jenkins broke the world land speed record for a wind-powered vehicle with a sailboat on wheels driving across a dry lakebed at 126 miles per hour. After years of engineering development, his technology has now taken on the form of a saildrone that can autonomously sail the sea gathering ecologic, oceanic and atmospheric data.
Coral Nurseries
In the past, coral conservationists focused their efforts on protecting reefs from direct environmental threats such as land-based pollution and damaging fishing practices. These efforts continue, but as coral reefs face increasingly dire threats, conservationists are turning toward more proactive approaches.
Wastewater Instead Of Dams
The era of dam building is coming to an end in much of the developed world. Dams are very expensive, environmentally harmful, and as the climate warms and droughts become more common, are not that reliable.
V2V And Safer Cars
Automated cars are coming, but they face many challenges in sharing the roads with human drivers. The on-board sensors in these cars are very effective in many ways, but they cannot see around corners or see through buses or trucks. They won’t know if six cars ahead, someone has slammed on their breaks leading to a chain-reaction collision. Of course, human drivers have the same problems.
Fighting Methane With Bacteria
Bacteria may have an important role to play in the effort to reduce greenhouse gas emissions. A group of researchers at the University of Alberta are genetically engineering non-hazardous bacteria that consume methane and turn it into fuel.
An Accidental Plastic Eater
A couple of years ago, scientists in Japan discovered bacteria at a recycling plant that were breaking down a type of plastic called polyethylene terephthalate, or PET. With the world facing a growing plastic pollution problem, British and American researchers began to study the enzyme that the bacteria were using to try to understand how it works.
New Jersey Wind
New Jersey may host the second commercially operating offshore wind farm in the U.S. as soon as 2020. The company EDF Renewable Energy is moving forward with a plan to bring online a 24-MW farm sited off the coast of Atlantic City.
Investing In Solar Power
The total amount of solar power capacity installed in the world reached 100 gigawatts in 2012. Getting to that amount took decades. But things have changed in dramatic fashion in recent years.
A Bad Food Patch
A group of scientists and engineers at McMaster University in Hamilton, Ontario, has developed a new technology that could replace traditional “best before” dates on food and beverages with a definitive indication of the safety of the product.
A Robot Fish
Scientists studying marine life have to figure out ways to get cameras into areas that are too dense or dangerous for people to enter. This often means sending delicate equipment into places where collisions are both likely and damaging and that equipment is generally tethered to ships or other objects. To really see what is going on in the underwater world, a better approach is needed.
Are We Drinking Plastic?
Almost everyone everywhere comes into contact with plastic everyday. Its use has increased 20-fold in the past half-century, and production is expected to double again in the next 20 years. But is plastic so ubiquitous that we are unwittingly drinking the stuff?
A Milestone For Energy Storage
The United States has now added the capacity to store a billion watts of power for one hour and it may double that total by the end of this year. According to the firm GTM Research, the energy storage industry – previously nearly invisible – is undergoing rapid growth. Much of the growth has been in homes with products like the Tesla Powerwall but has also been on the scale of the electric grid, where power companies can use storage to control when to deploy excess electricity generated from renewable sources such as solar power.
Listening To Volcanoes
Volcanoes are complicated, and we don’t have universally applicable ways to predict when they might erupt. Measurements of seismicity, gas emissions and ground deformation are all useful in trying to figure out what volcanoes are up to. However, it is unlikely that will ever have definitive prediction techniques.
Sunshine To Fuel
Hydrogen is touted to be the fuel of the future, particularly for cars. But a more acccurate view of it is that hydrogen is an energy storage medium. And the most promising form of energy to store using hydrogen is solar energy.
Making Self-Driving Cars Safer
We hear quite a bit about self-driving cars these days. More and more cars on the road have at least some ability to do things on their own (steer, brake, or park) and some can do much more.
Renewables Beat Out Coal In Europe
Last year was the first year in which more electricity in Europe was generated from the combination of wind, sun, and biomass than from coal. The combination of all clean energy sources (which adds hydropower to the mix) surpassed coal several years ago.
U.S. Offshore Wind Powering Up
After many years of false starts and delays, the offshore wind industry in the U.S. finally seems to be gaining momentum. According to the Department of Energy, more than 25 offshore wind projects with a generating capacity of 24 gigawatts are now being planned. Most of these are off of the Northeast and Mid-Atlantic coasts.
Major Investments In Solar Power
There is big money going into renewable energy and energy-smart technologies and half of that is going into solar power. In 2017, global investments in green energy reached $334 billion and $161 billion of that was in solar.
The Automobile Future: Dream or Nightmare?
Visionaries tout a future in which cars are electric, self-driving, and shared. All three of these things are starting to happen today, but will they come together to produce a future where congestion and pollution are things of the past?
