America's first wave-power farm is under construction off the Oregon coast. The system generates energy as waves on the surface of the ocean move a large, buoyant plunger up and down. This is the first of ten buoys that are being set up in the area at a total cost of $60 million. If they work, they'll power about 400 homes.This form of renewable energy presents some challenges though:
Some don't believe wave energy can work, said Onno Husing, director of the Oregon Coastal Zone Management Association."A lot of people who are very experienced with the ocean harbor a lot of doubt that anyone can in a cost-effective way put buoys in the water, harvest the energy, and not have them end up on the beach," he said.The world's first commercial wave farm opened in 2008 off the coast of Portugal, at the Aguçadoura Wave Park, Husing said. It ran into financial difficulties last year and was suspended indefinitely, according to a statement from Pelamis Wave Power of Scotland, part owner of the project.A wave-power device from another company, Finavera Renewables of Canada, sank off Oregon's coast two years ago, Pellegrino said.
The advantage of wave power over solar and wind is that it's more predictable. Let's hope this works out for Oregon.

A study out of Belgium found that smart people are much less likely to be bigoted. The same study also found that people who are bigoted are more likely to overestimate their own intelligence.

A horrifying story out of Germany is a perfect example of this truth on full display: an anti-Semite was so dumb the was unable to open a door at the temple he tried to attack.

On Wednesday, October 9, congregants gathered at a synagogue in Humboldtstrasse, Germany for a Yom Kippur service, and an anti-Semite armed with explosives and carrying a rifle attempted to barge in through the door.

The old saying goes something like, "Possessions don't make you happy." A more dire version is, "What you own, ends up owning you."

Are these old adages true or just the empty words of ancient party-poopers challenging you not to buy an iPhone 11? According to a new study of 968 young adults by the University of Arizona, being materialistic only brings us misery.

The study examined how engaging in pro-environmental behaviors affects the well-being of millenials. The study found two ways in which they modify their behaviors to help the environment: they either reduce what they consume or purchase green items.

One of the biggest obstacles to getting assault weapons banned in the United States is the amount of money they generate.

There were around 10 million guns manufactured in the U.S. in 2016 of which around 2 million were semiautomatic, assault-style weapons. According to the National Shooting Sports Foundation, the firearms industry's trade association, the U.S. industry's total economic impact in 2016 alone was $51 billion.

In 2016, the NRA gave over $50 million to buy support from lawmakers. When one considers the tens of millions of dollars spent on commerce and corruption, it's no wonder gun control advocates have an uphill battle.

That, of course, assumes that money can control just about anyone in the equation. However, there are a few brave souls who actually value human life over profit.

Trees give us a unique glimpse into our past. An examination of tree rings can show us what the climate was like in a given year. Was it a wet winter? Were there hurricanes in the summer? Did a forest fire ravage the area?

An ancient tree in New Zealand is the first to provide evidence of the near reversal of the Earth's magnetic field over 41,000 years ago.

Over the past 83 million years there have been 183 magnetic pole reversals, a process that takes about 7,000 years to complete.

The final episode of "The Sopranos" made a lot of people angry because it ends with mob boss Tony Soprano and his family eating at an ice cream parlor while "Don't Stop Believin'" by Journey plays in the background … and then, suddenly, the screen turns black.

Some thought the ending was a dirty trick, while others saw it as a stroke of brilliance. A popular theory is that Tony gets shot, but doesn't know it because, as his brother-in-law Bobby Baccala said, "You probably don't even hear it when it happens, right?"

So the show gives us all an idea of what it's like to die. We're here and then we're not.
