Comment Re:Penn and Teller should do a Bullshit episode (Score 1) 327

But take a look at any major city's rush hour and then imagine all those cars going home to plug in and you can see the potential for a huge problem.

So utilities will have to install smart metering with control over charging stations. There, fixed that for you.
The more interesting application will be when cars are uses as storage devices, so peaks are supplied by car storage. Add solar and inverters and the grid becomes very flexible, robust, sustainable and reliable.

Comment Nothing to see here (Score 1) 380

This is a story about a facility closing and the town losing jobs, this is not a story that supports Nuclear. If you are want to build nuclear plants to create jobs, the tail is wagging the dog. Supposing, just supposing, the plant had an accident and all those people had to evacuate. Do you think they would have been sad to see it close? Now that would have been a nuclear story.

Comment Forget cameras (Score 1) 272

I install cameras for customers, and I would advise you to forget CCTV as a way to stop break-ins. I get a lot of prospective customers who want cameras to deter intruders and advise them the same way. Good camera systems, which pretty much leaves out video, is useful to catch shoplifters, light fingered employees, improper use of resources, and reduce liability in the event of an accident and law suit. If you want to stop intrusion, secure the property (if they got through bars, you need better bars), and have a professional company install an alarm with central monitoring and security staff.
Getting a picture of an intruder is useless. Getting a picture of an intruder wearing sunglasses is even more useless.

An Alarm with glass break, lights, loud siren and guards on the way ought to stop them. If it doesn't, move.

Comment Emmissions (Score 1) 165

Wouldn't it be easier to reduce emissions as recommended by every decent scientist for decades? I am tired of all the oddball solutions that are being put forward instead of a mature response to the problem. The leaders and voters get to avoid the hard decisions because they believe the magic solution is just around the corner. We need to face up to the problems we have created and work towards solving them, not looking for the "magic" solution that will make all the bad news go away.

Comment Greed (Score 1) 655

Forget all the science, the diets and the theories. Americans are fat, generally, because they stuff as much food in their mouths as they physically can. Then they eat more. They are greedy. American culture is based on enjoying as much of life's pleasures as conspicuously as possible to demonstrate your success. It's cultural and is all based on the "winners take all" and "success is good" mentality that has made America the best place in the world to live. However, it comes at a price.

Comment Why don't they setup in Anguilla, BWI (Score 1) 332

The same companies can set up in Anguilla, be outside the US, have no corporate tax, have real tax treaties and IP treaties, and go to the beach after lunch. Fiber to the US, low latency connections, stable economic situation and no need to rely on the boat owner to keep the thing afloat.
Handled properly, they would have much less hassle.

Comment Re:It's not about the poor (Score 1) 415

After many years of failed theories on the right way to make it happen, Feed In Tariffs have been recognized as the only successful way to incentivize RE projects. However, no-one knew solar would plunge in price so abruptly as it did recently. The uptake of the offers has been exceptional.
It will stabilize and solar will see continuous adoption everywhere, especially where electricity is expensive.
The idea that the adoption of solar punishes the poor is a bit like saying building libraries punishes the poor because they read less. Not everything directly affects everyone the same way, that isn't possible. Consider an example relevant to my location. If you have a job working for a company that is going under because of the operating costs, mainly energy, then encouraging that company to invest in solar pv would help to ensure that person had a job for the future. The family also benefits.
Everyone benefits from policies that increase energy security, encourages inovation and develops intelectual property. Renewal Energy is the next (current?) technology race, ignoring it could be a mistake that will have lasting repercussions.

Comment It's not about the poor (Score 4, Interesting) 415

I hear this same argument all the time here in Anguilla where I live. "we don't want solar unless it reduces the cost of electricity for the poor man".
It's nonsense because solar is not going to drop the wholesale price of electricity, the differential from the price of NG or Nuke is never going to be substantial enough. Electricity in America is very very cheap. There is little point in trying to reduce the cost further, it is mostly administration charges at this stage.

The reason countries like the USA and other are promoting solar is because it is a renewable source. OIl and other fossil fuels are filthy and news of their imminent demise is not exaggerated. They will run out. America has a responsibility as a first world nation to reduce emissions.

Turning to renewable sources allows more time before the end of oil and for the technologies to develop. You can't expect we can transition once there is a crisis. Unless we start now and incentivize the use of RE, we will never get to a point where we can manage without fossil fuels. Great strides are being made and the discovery of grid based storage at economical cost will be a game changer.

Another reason to promote RE sources is energy independence. If countries that are not in the Middle East could survive on domestic production and renewable sources, the politics of the world would change dramatically, and the price of energy would drop, spawning another economic boom. At present, the US public is crying about high gasoline prices caused by geopolitical issues, but at the same time complaining about subsidies for renewable sources aimed at developing solutions to this issue. And blaming Obama for both.

Let's make this very clear. Oil will get more and more expensive until it runs out, the planet will warm in the mean time from CO2, and there will be instability in the Middle East and Venezuela. Or you can believe the Forbes and Fox News stories that tell you the opposite.

I live in a country that has probably the highest electricity costs in the world, 43c/KWh, unlimited sunshine, and refuses to allow people to install solar. Figure that policy out. Very soon we will not be a viable state because of high energy costs, but there is still no vision or will to move out of the dark ages.

Be glad you at least have the right to install solar or wind or whatever.

Some money just deserve to be taken.

They don't deserve to be taken, they WANT to be taken. I work in audio and the people who can pay someone to put in a home theater are not happy to be told not to buy "oxygen depleted molecular aligned copper" cable to make the digital sound crisper - they WANT to think they have some special item so ridiculously expensive for what it does that the average Joe cannot afford it.
If they really wanted the best sounding equipment, they would buy professional gear, which is what the music is recorded with.
They don't, they want the most esoteric, bullshit laden nonsense that the magazines are pushing.
However, HDMI sucks and just doesn't work, so anything that offers a better solution and has widespread support is welcome.
But the idea that it will be popular in a year is stupid, there are no devices with this interface> It will take years to get mass adoption and be accepted.
