A New Catalyst For Splitting Water
Hydrogen is widely considered to be a desirable source of clean energy. It can be used in fuel cells to power electric motors in cars or can be burned directly in internal combustion engines. If it is compressed or converted to liquid, it can be efficiently stored and transported. Most of all, when it is used as an energy source, the only emission it produces is water.
A Better Way To Make Hydrogen
There is a great deal of interest in developing cost-effective, energy-efficient and environmentally-friendly ways of producing hydrogen. If hydrogen-powered vehicles are to catch on, it is essential.
New Rules For Ocean Conservation
In a recent report to a United Nations ocean conference, scientists are warning that new rules are desperately needed to protect marine life in the open seas. That’s because more than 60% of the ocean has no conservation rules since it’s located outside national jurisdictions. The open ocean is at risk from climate change, over-fishing, deep sea mining, farm pollution, and plastics pollution.
An Aluminum Battery
The battery industry is currently dominated by lithium-ion batteries. We have them in our phones and computers. They power electric cars. And they are increasingly being used to store energy generated by solar panels and other renewable energy sources.
A Hydrogen-Powered Train
It seems like something out of a science fiction movie, but a nearly silent train that glides along its tracks emitting nothing but water is a reality. In March, Germany conducted successful tests of the world’s first “Hydrail,” which is a hydrogen-powered, zero-emission train.
Threats To Coral Reefs
There has been much news recently about the growing bleaching events going on in the world’s coral reefs associated with ocean warming and acidification. The massive damage to Australia’s Great Barrier Reef is an ongoing tragedy.
Hydrogen On Demand
Researchers at the Technion-Israel Institute of Technology have developed a new method for producing hydrogen from water using solar energy. If successfully developed, their approach would make it possible to produce hydrogen in a centralized manner at the point of sale such as at a fueling station for hydrogen-powered cars.
Ocean Oxygen Levels
When we think of global climate change, what comes to mind? Rising seas? Melting glaciers? Shrinking sea ice? How about diminishing ocean oxygen levels?
Climate Change And Fish
According to a recent study published in the journal Global Change Biology, rising CO2 levels in the ocean can disrupt the sensory systems of fish and can even make them swim toward predators and ignore the sounds that normally deter them from risky habitats.
Plastic From Milk
These days, many of the foods we buy, such as meat, bread, cheese and snacks – come wrapped in plastic. We end up with lots of non-recyclable, non-biodegradable waste. And thin plastic films are not even that great at preserving food because oxygen still gets through them.
The Value Of Street Trees
Why should you care whether there are trees on your street or on the streets nearby? Besides the obvious fact that they make streets more attractive, street trees provide a number of real benefits both for residents and for the environment.
Stop Putting Food Waste Down The Drain
Should we really be putting food scraps down our sinks? Advertisements for kitchen garbage disposals assure us that these devices are a ‘hygienic way of eliminating waste and keeping odors at bay’ – but behind marketing materials questions remain.
Climate Change And Buzzards Bay
The effects of climate change are being felt around the world, including in some well-known places in the Northeast. Buzzards Bay is a popular destination for fishing, boating, and tourism adjacent to Cape Cod in Massachusetts.
Road Salt
Snow season is here. The chances are good you’ll find yourself behind a truck spreading salt on the roads in an attempt to deice them. You may even try a little salt on your own front porch. Annually we spread about 20 million tons of road salt in the U.S., and we’ve been doing it since the late 1930s.
