The problem with modular addition is that the power conditioning equipment and professional installation required to sell back to the grid tend to cost several thousand dollar, regardless of the amount of energy your selling back.

Starting small can work if you want to play around with it yourself, but when you connect to the grid you get into big trouble if you don't meet all of the utilities requirements.

Comment: Radioactive Fuel... (Score 1) 486

This reminded me of some of the plowshares experiments (where they tried to come up with non-war uses for hydrogen bombs) Link

One of the ones I remember being interesting was the use of underground detonations to break up rock and free natural gas (think super-fracking), it was tested and worked with only one problem, it was horribly inefficient and not cost effective, oh and all the natural gas was radioactive. As with all the plowshares crazy ideas this one didn't quite pan out, but it amazed me that they actually tried it. Oh and just to be sure they did it 3 times.

In the pacific northwest (Seattle Area) my calculations show break even at around 18 years, which is pretty bad given that, the panels are only usually rated for 15 years.

Every few years I get to thinking about doing it and I run through the calculations and come up with similar numbers, panel prices are down, but power conditioning set-ups are still a big part of the cost, and then you have to pay for a contractor to install the setup (one of the largest parts of the cost) if you want to get any of the tax credits or connect to the grid.

Looking at my last utility bill, 99% of my energy is coming from non fossil fuel sources, hydroelectric mostly. So green guilt is not going to get me to put PV on my house and it doesn't really make economic sense either.

I'm sure I'll run the numbers again in a few years when I need to re-roof the house; I like the idea of energy independence, but where I live Solar PV is just not cost effective.

Seriously Diablo?? WTF is that a typo and supposed to be DIablo II or 3, are people still playing single player Diablo, a few years back I installed it in a VM to get some nostalgic gameplay and it was horrible.

People are scared of radiation because they don't understand it.
Rather then educate children todays society is more concerned with protecting them.
Relevant XKCD for dosage information.
I would be interested in how many banana doses of radiation this kit contained.
Everything is radioactive, granite countertops, bananas, sea-salt, living in Denver (higher elevations), hell carbon dating works because all life is radioactive.

The fed controls the other governing bodies through the simple means of money.

Do you want that federal funding for your state, better not enact laws against the will of the federal masters.
Local cops want some new tech from homeland security, better have policies in place that meet federal standards. (oh and sign this NDA)
Want federal funding for interstate highways, your drinking age had better be 21.

Originally the constitution prevented this by preventing the fed from directly taxing the people, limiting the amount of money they had, the federal income tax is the source of this problem, give enough money to the fed and you give them power over every policy imaginable.

The fed may not be the ones in your face daily, but they are the ones directing a large number of locally enforced policies.

Chemical batteries are also, generally the cheapest most compact method to store electricity, which is what you need to run servers, if all you want to do is store energy, hot water is a better method.

All the other storage methods have huge losses when trying to get electricity out, requiring larger and larger storage capacity to deliver the required electricity.
