I always try to park in the shade on a sunny day so the inside of my car won’t get so hot.
If solar cars become practical, I’ll want to park in the sunniest place I can find.
When will electric cars with solar panels on the roof be available? Continue reading →
Many businesses have begun to focus on green practices in product packaging.
But at the same time, many of the most encouraged practices cost money to implement.
These financial challenges can put businesses off making the move.
Being green might entail some cost for your organisation. But taking steps to become more environmentally sound offers some reward. Here are five of the biggest business benefits of eco-friendly packaging. Continue reading →
We toss our recycling into a single container. Then a truck hauls it to a materials recovery facility (MRF).
Sorting it is monotonous and potentially dangerous work for humans.
Some manufacturers have developed robotic sorting systems.
This infant technology has enormous potential. Robots don’t slow down. They don’t need breaks or vacations (except occasional down-time for routine maintenance). They can work continuously all day and night.
With artificial intelligence (AI), they can learn to separate, say, one plastic from another, as well as human sorters. So far, though, it doesn’t appear that robotic sorting can completely eliminate the need for human eyes.
AI promises to reduce a MRF’s operating costs, speed up their processes, and improve the quality of their output. Can it work economically? Continue reading →
After water, sand and gravel are the world’s most abundant resource.
In recent decades, the we have mined—and wasted––so much of it that the we’re actually running out of sand.
People have used sand for construction since prehistoric times. It is the chief component in glass.
Recently discovered processes also depend on sand. These include silicon chips for electronics and fracking.
Demand will continue to grow into the foreseeable future. And demand has begun to exceed supply. Continue reading →
A local renewable energy skeptic recently wrote that a blackout in Australia proves wind energy isn’t reliable.
When several wind farms shut down at once in bad weather, it plunged an entire state into darkness. Naturally, I had to investigate.
The massive power outage in South Australia in the wake of tornados last September immediately led to partisan bickering. Did the state’s heavy reliance on wind energy cause the blackout?
The Bureau of Meteorology (BOM) issued a report on the tornados that swept the state. The Australian Energy Market Operator (AEMO) issued four reports that explained the events that led to the outage. Continue reading →
Our current agricultural system can produce plenty of food. It’s just not very good at distributing it.
Food deserts have appeared in our cities.
People living in poor neighborhoods have no conveniently located stores where they can buy fresh produce.
