I think something similar has shown up in the original "Journal of Irreproducible Results".Comment

So, that's 0.2 J/oz fart energy for a flea. For a 170 pound human, there is 147/(170*16), or 0.04 J/oz ordinary fart energy.
If we estimate that a beer fart is five times as powerful as an ordinary fart, we arrive at the interesting result that the fart energy per unit weight for the ordinary flea and average human expelling a beer fart are on a par. Fascinating.Comment

Well, now we're getting somewhere. A flea fart contains 1eV, or 1.60217657 × 10-19 J. An ordinary flea weighs 220 x 10-6 g, or 7.8 x 10-6 oz.

It is the introduction of non-natural alcohol that leads to the prodigious production and perturbs the expected result.Comment

Seat of the pants logic says that the flea's production should be more efficient, and the rough calculations confirm that the production of a human who abstains from alcohol consumption is inferior due to the law of diminishing returns.

I'm done.Comment

Since they seem stealthy by definition, perhaps the SBDF's could somehow be accounted for in the imaginary plane as part of any power factor loss.
This thread is sinking fast. Perhaps a moderator could put it out of its misery via thread euthanasia. I think we're way off topic.Comment

Back on topic.
On the sunny days during peak times it looks like I'm getting about 2 amps out of the HF solar panels. I replaced the HF charge controller with a Windy Nation PL30 PWM. I bought the PL30 because it allowed me to see other than the single voltage reading from the HF controller. I have no idea how efficient or accurate it actually is.
If I did the math right. 2 amps at 12 volts [watts=voltsXamps] for the peak sun hours for my area of 4.5, I get a whopping 108 watt hours or 0.108 Kwh.Comment

So far I've got about $250 tied up in it. From the info I was reading before, (sources other than SPT) I was getting the impression that you didn't want to buy a panel or panels and then add to them at a later date. Same with your batteries. As stated before I don't have a specific Kwh goal at this time and am just trying to learn more about solar without dumping a ton of money while I learn.
Considering the panels I have, what controller would you buy to connect to them? I'm pretty sure there isn't one because the panels themselves are also POS. If I was to go back in time and do it all over what could I have done with the $250 in the way of a decent panel(s) and controller?Comment

You can get factory Seconds GT panels for as low as 63-cents per watt. You paid over $3/watt for a box for the kids to play with. Nothing in the HF kit is usable. Well you could use it to charge cell phones and a laptop. At best in TX generates less than 1-cent of electricity per day. But to make it useful requires a battery and inverter at additional cost.MSEE, PEComment

To start you would use Grid Tied panels at $1/watt or less instead of battery panels that cost $2 to $8/watt. Does that help clear things up?

At most a small backup system that I could use to power a coffee maker, charge a couple of cell phones, a laptop, or even run a tv or radio for short periods of time during power outages.
Maybe a battery bank, trickle charger and power inverter would be a better solution or small generator.Comment
