Seafloor carpet taps power of waves to generate energy (w/video 2min)

Seafloor carpet taps power of waves to generate energy (w/video 2min) | Landscape Irrigation | Scoop.it

UC Berkeley engineers are developing a seafloor carpet system to capture ocean wave energy and convert it into usable electricity. The system could eventually help lower the cost of converting seawater into fresh water, easing the pressure during periods of drought.

 

For assistant professor Reza Alam, an expert in wave mechanics, the seafloor “carpet” he is proposing will convert ocean waves into usable energy.

 

“There is a vast amount of untapped energy in the oceans, and with increasing worldwide demand for power, the need to find cleaner alternatives to fossil fuels is critical,” said Alam. “We are also seeing greater population growth along coastal cities, so the ocean-based system we are developing would produce electricity in a carbon-neutral way right where it is needed.”

Apparently waves are pretty energy dense and could be used to generate power in a simple way...

"Alam estimated that one square meter of a seafloor carpet system could generate enough electricity to power two U.S. households.


He added that wave energy from just 10 meters of California coastline, or about 100 square meters of a seafloor carpet, could generate the same amount of power as an array of solar panels the size of a soccer field, which covers about 6,400 square meters."

its interesting to see what the great minds of this generation have proposed as alternatives to cleaner energy methods. seemingly plausible with little disturbance to any human activity. but what was unsettling to me was the fact that oceanic wildlife was not taken into account and what repercussions this potential project could bring to the organisms currently seeking refuge in the ocean.

Australia: New Plastic Means Almost Anything Can Be Made From Hemp

Australia: New Plastic Means Almost Anything Can Be Made From Hemp | Landscape Irrigation | Scoop.it

Today's plastics are made from petroleum, which means we are polluting the atmosphere and putting products that cannot biodegrade into our environment. But Zeoform, a new company based in Australia has created a new kind of plastic made only from water and cellulose taken from hemp plants -- meaning the plastic is not only eco-friendly but biodegradable.

 

The company's patented process converts the cellulose fibers found in hemp into a super-strong, high tech molding material capable of being formed into 100 percent nontoxic and biodegradable products...

 

The company says their product relies only upon the natural process of hydrogen bonding that takes place when cellulose fibers are mixed with water. No glue or other bonding material is necessary, because the bond already created is so strong.

 

The final material can be turned into almost anything, and can be cut, routed, machined, drilled, screwed, nailed and glued in the same way wood can be.

Great renewable material that is also biodegradable...

It's High Time to end the U.S. ban on industrial hemp!
