That's true.  A grid tie inverter watches for an existing sine wave coming from the grid, to which it can synchronize its own output.  If it doesn't see one, it produces no output.

A regular inverter will blindly produce output but you can't tie that into your main panel.

FEEDING THE BANK. A solar installation sufficient to do what your buddy

seems to have done runs around FORTY GRAND. And that Tesla costs about


Taking your numbers at face-value because I don't know any better, and assuming the 40,0K is funded by a mortgage refinance at 3.891%, your monthly payment increases by $230.13 (and your property tax bill by some $42.)

Not quite worth it at present prices, but if your assumption is that nominal energy prices will continue in their upward march over the next 30 years, you could come out ahead...

Calculate the break-even time. It's damn near an ETERNITY...

Considering that the currently available photovoltaic panels are rated for 10 years of 90% or better output, followed by 10 years of 80% or better output, with an average service lifetime of 30 to 35 years ... it seems unlikely that ROI will ever be realized at current prices.

It's going to take a technology breakthrough to make solar a feasible mainstream energy source.

The obvious breakthrough would be for biologists to develop an organic substrate that duplicates photosynthesis, absorbing sunlight/CO2/H2O and releasing a liquid fuel.

Well... they do have something rather close. And it all developed without any help from biologists!

COWS + FOOD ==> FERTILIZER + METHANE + MILK + MORE COWS

Now *that* is a self-renewing energy/food source!!!!!

why not? i.e. the rotzkocher did similar ( http://www.autogas-freun.de/index.php?page=Thread&threadID=3523 ) 60 years ago.

the only problem is ... howto catch the farts and burps.

Harness my uncle or any of my 3 brothers.  That should power a couple hundred of those things, anyway.....

Methane is actually the primary component of "natural gas" (no pun intended).

Capturing bovine flatulence is not an efficient way of turning food into fuel, though. Considering how much food a cow needs to eat, it would be far more efficient to simply ferment the food and extract ethanol (or whatever) from it.

Vegetarians should stop reading here.

Cows are far more useful as food/fuel for us. Steaks and burgers all the way down! Cooked using conventional energy with its artificially inflated prices. I CAN HAS CHEEZBURGER!!!

Oh look, I have steaks in the fridge. Big slabs of cow on the grill for my family tonight!

...which is somewhat of a curiosity considering that a major portion of legitimate science considers bovine flatulence to be one of the major contributors of greenhouse gas production...

Ah, but IG - if we could use the methane as fuel for cars or whatever, and then use the nice big, juicy slabs of beef as fuel for humans....

I thought I read somewhere about turning garbage into fuel.

Something about dumping it all into a huge vat and heating it into a slurry somehow turns it into fuel.

Yes, a processes developed by Doc Brown for his Flux capacitor.

Unless you are thinking of this processes:

Methane is actually the primary component of "natural gas" (no pun intended).

you however can also generate this in the silos where cow excrements are collected.

There are places where a process like this is used.

In some locations, methane is captured from landfills, where it is produced naturally from the degradation of buried garbage. Despite the HitlerSierra Club's claim that "nothing degrades in a landfill," there are actually significant landfill gas capture projects out thee.

Far more common, however, is methane capture in sewage treatment facilities.
For obvious reasons, methane is produced in significant amounts. Traditionally they just flared it off, but facilities that have installed digesters are often capturing enough methane to supply all of their own energy needs.

On the subject of renewable energy, this company was founded by a high school friend who went on to study engineering at MIT. They have a plan to build cost-effective wind and wind/solar hybrid power systems for homeowners...

Back to the Citidrift subject of cows, I have to eat my words on the poo-poo'ing of "natural fed" meat being any different from "regular" meat.  Out in CO there are so many damned cows, the whole place smells like a methane factory - most (or many) of which are "naturally fed".

But - I have never tasted such amazing beef.  It doesn't just taste "different", it tastes *better*.  It's richer and leaner, yet somehow also more tender. 

Now I really gotta find a kosher butcher in CO that will ship out to MA.....

What does "naturally fed" mean? I understand grass fed, but one could argue that all cattle feed is "natural", including that which consists of ground up cows...

Plenty of grass-fed beef available in the Hudson Valley--less risk of mad cow from that stuff.
