I thought a lot about battlestar galactica in the last few years as I was trying to help rid Twitter of bots

@itsmaibirfday intrigued with that dialogue. Frightening and interesting what a I can do.  I’m not at all versed in AI and so I just keep going back to Stanley Kubrick’s film 2001 space odyssey where the computer Hal takes control of the ship and the only recourse the human has is to disconnect the computer. 

So how many episodes of the series do I need to watch to get a sense of things and where do you start? Is it on Netflix?

A pilot trial for wave energy on King Island has been successful and generated enough electricity to power 200 homes. Another way for renewable energy.

Regards to all

I love the idea of wave energy!  This is very hopeful for communities along the ocean!

This is such wonderful news.  Thanks for posting. We may be living through troubled times, but these ideas give us so much hope for the future.

I vaguely remember someone predicting breakthroughs in energy technology, and I've been following these two stories about new battery technology (here and here) lately.  Both are good options, but the second is further along in research and may be more viable given its biodegradable/recyclable properties.

Very interesting concept using crab and lobster shells ---one hitch, as the oceans absorb atmospheric carbon dioxide (as a result of burning fossil fuels), they, become more acidic, (search Ocean Acidification) the change in water chemistry makes makes it hard for sea creatures to build their own shells. I wonder if they envision "farming" these sea creatures.

@raincloud I'm going with the more optimistic view that as electric power surges forward and becomes more widespread, the levels of atmospheric CO2 will begin to drop and preclude that.  I'm only mildly pollyanna-ish. ;-)

I wish....it won't happen fast enough, I fear. It will take massive CO2 extraction and sequestration to stabilize the climate and the oceans. Also, oceans have absorbed ~93% of the excess heat from global warming which will be slow to reverse. Warmer waters threaten sea creatures so a number of species are already moving out of their natural range and or dying off. The increased warmth and ocean acidification is a perilous combination for marine life. The tiny creatures at the bottom of the food chain, like benthic organisms and krill are already having trouble.

There is push back in the environmental world against carbon capture and storage/sequestration technologies because of the large amount of money it will take to get it up and running. Many would rather see those monies spent on alternative energy but in order to stabilize the glaciers and ice caps, we have to reduce atmospheric CO2 to below 350ppm. I don't see how we will get there without deploying carbon removal technologies.

I agree, however, that "they" will figure out how to produce much less toxic and ultimately recyclable batteries and relatively soon.

Speaking of tech, have there been any predictions relating to artificial intelligence, AI? Stephen Hawking issued a warning in 2014.
