Alternative Energy

Could this change everything?


Lockheed says makes breakthrough on fusion energy project


(Reuters) - Lockheed Martin Corp said on Wednesday it had made a technological breakthrough in developing a power source based on nuclear fusion, and the first reactors, small enough to fit on the back of a truck, could be ready for use in a decade.

...


Compact nuclear fusion would produce far less waste than coal-powered plants since it would use deuterium-tritium fuel, which can generate nearly 10 million times more energy than the same amount of fossil fuels, the company said.

Ultra-dense deuterium, an isotope of hydrogen, is found in the earth's oceans, and tritium is made from natural lithium deposits.

It said future reactors could use a different fuel and eliminate radioactive waste completely.

Seems like a breakthrough to me.

However, why would Lockheed Martin stock drop 1.25 % following the announcement?

That is curious, though with a prototype 5 years out maybe its not enough to overcome the ebola panic.

A big breakthrough may be forthcoming in battery technology.

Car batteries may soon last 1,000 years thanks to pine and alfalfa

Why would a battery company want something to last that long, they need the repeat business, they would pretty much destroy there business model if batteries lasted this long.

This same dilemma is being faced by manufacturers and distributors of LED light bulbs. If the customer only buys once every 20 years, how does your business model work?

Why????

Well, why not?????

If there is a demand large enough then they will meet it. Just think of other uses that could come about. Why are they pursuing development of these products if they are worried about being out of business some time in the future?

The lifecycle of a product is so much shorter now. If someone is thinking about 20 years from now, their business isn't going to last very long. Things move to fast to be looking that far ahead. Of course, this has caused the almost complete elimination of the family business in society today.

The media is hyping this a little too much and many scientists are very skeptical about their results. Even Lockheed admits their results are just theoretical and will be difficult to apply in real world. Is still important to keep at it as there can still be some things learned that morph into other ideas that can be useful.

http://www.businessinsider.com/scientis ... on-2014-10

There have been many battery 'breakthroughs' over the last 20 years too but there still hasn't been any significant breakthrough that has ever made it to market. Usually it ends up not cost effective to get into mass production, but there has been some incremental improvement. There's been better progress with devices/components drawing less power than creating/harnessing/storing clean energy at a mass produced scale - supplemental yeah, but not enough to replace 'dirty' energy.

This doesn't sound like pseudo science but the science industry needs to do a better job managing media reports before getting peer reviewed, which will be a while because Lockheed isn't disclosing much yet despite patents - no papers have been released yet. Remember the 'breakthrough' a few years ago that claimed particles moving faster than light? Media took off with it before peer review and it turned out to be incorrect.

you add technology of course.

look at how many new smart lightbulbs are on the market versus even a year ago.

today a lightbulb does color and wifi.

imagine when they have motion detection and ambient light sensors built into the package and standalone so a room can automatically set lighting based on where you are in it and time of day. each light turns on based on someone being in the room. thinking like those LED bars that come as a package or maybe in a ring around the bulb itself.

And yet, people are freaking out about the potential to lose coal jobs. Everyone in every industry is at risk in the modern era of technology of being replaced overnight. We really need to do a better job at offering opportunities for folks to shift careers instead of holding on to industries and industry models that are no longer necessary or are holding society back.

Coal production and consumption is down in the US and China but still increasing globally (especially India) and expected to long term. US and China may decline a bit over time but still expected to have major consumption over time...
https://www.eia.gov/forecasts/ieo/coal.cfm

Would expect US production to go in cycles but ultimately that all accessible coal is eventually extracted, just maybe slowed down (and just a slow decline). Money is power and unfortunately the US is heavily driven by lobbyists. It doesn't make sense that $Bs worth of easily accessible coal will just sit there forever. The alternatives are still supplemental for the most part but even if/when it could replace coal/fossil fuels, and there are isolated successes in some small countries, as long as money can be made from coal, production probably will continue until all gone unfortunately.

I'm not arguing that coal will die an immediate death. I'm stating that coal jobs are probably going to diminish greatly in the future, though, and this is inevitable. All that is up for debate is how long it will take to significantly change the industry. People are freaking out about it in relation to emissions and coal generation regulation in the US, but if, as you state global demand increases, the US consumption won't be as important as the market shifts to ship overseas.

Incentivizing alternative energy is almost inarguably good for the environment and the long-term health, beauty, reliability, and efficiency of our country. Really the only pro-coal arguments out there are based on its economic benefits. Why we would ignore the potential of alternative energy to preserve jobs in an industry that we don't need as much anymore makes little sense. Local communities will continue to determine if coal mining is right for them, but the global market will still be there to dictate its value. This cost of coal may not be wildly shifting, but the value to various markets is. If it is growing in value globally, then people need to stop blaming US regulation on killing jobs.
