Shouldn't we be carrying around solar panels?

[bean2k21]

How can anyone say they love Mother Earth? Everbody carries a mobile device, yet when it runs out of juice, what do they do? Beg for some fossil-fueled energy behemoth to recharge their precious handheld. If we really cared, we would all have a global storage padded utility panel solar bag, double layered and fitted for a 100-watt recharge.

My partner and I have laptop rucksacks from Amazon, They include a pocket inside for a powerbank. We each got a small solar charger that clips on the rucksacks. Charges the powerbank which keeps out phones and tablets charged.

If only we could find one withbenough guts to charge our laptops.

For sure and i have attached one to my harley hat so my brain functions at its optimum. And the downside is I read all the damn drivers in traffic mind. I've almost gotten in wreck flipping people off. I'm thinking about that hat on ETSY or EBAY or Mercari... where the Lefties are. SO MUCH FOR GOING GREEN !!!

Sounds like an entrepreneur opportunity for you. Good luck!

I think in sunnier climates solar power could be used to provide free charging points for people but here we'd be better off sticking windmills on out phones

[bean2k21]

I think wearable renewables are the way of the future.

Don't forget that the son rotates around us, and the panel only absorbs light from one direction. But I got a solar sphere that can absorb christ light from nearly 360 degrees. I often sunbathe my body in a way that raises testosterone, increasing my overall energy levels like none other flat panel plugged into my skin. Much more cost effective considering its size, who needs a pussyannel this way.

We could drive aluminum or carbon pipes into the ground, with it's diameter insulated, but open at the ends. In winter the deep ground is warmer than surface temperature. So connecting a peltier element between the two will generate endlessly.
Looking like this maybe


Never heard of this before. Turns out circulating compressed water heats homes, I guess then this should definitely work.

So it can work day and night, year round independent of wind, takes little maintenance. But isn't popular at all it seems. I would imagine someone tried it but it wasn't efficient enough for them. Well.. per capacity of energy generation it appears cheaper than solar to manufacture, as well as smaller size. So maybe thousands of them will power a home. However I can't afford drilling holes right now. The ground is now also frozen on surface.

Do you know of someone who tried this?

[Dildорhobe]

@Fuentes See this last reply. I'm actually looking for solutions, we all need a solution.

Wherever you all live, the ground is frozen in my location so I definitely won't drive conductors into ground until summer.

We know geothermal options are there but aren't the most affordable.

This, being my best solution I have yet come up with, and have not found anyone on the internet discuss. Maybe it's a shit idea for an obvious reason that I overlook. Then why doesn't anyone enlighten me. Should I ask on a different forum? Wherever I go, nobody has any solutions so it doesn't really matter which forum I'm on, it's the same.

Really good shit. it's a short paragraph

www.researchgate.net/.../285994120_Geothermal_power_generation_using_thermoelectric_effect

If the material is about equivalent to solar, then it's said to be 6 times as good because it's not always sunny outside.

So they got 160w using a 500w module and temperature difference of 80°C. Then, if you stick an insulated rod 5 meters into the ground, it's always above freezing point in January where I am, and the average temperature is maybe 20°C. That is 4 times less difference than they used in the study so I assume it's 1/4 the production, if the relationship is linear.
I would get constant 40w if the temperature is conducted well. To power the home, and a couple barns, will take at least 500 pieces of 500w modules. Sounds like a lot but I still haven't found what their price is and what space they occupy. It's said to be 1/20 in volume compared to a solar panel rated the same wattage.

[Opinion Owner]

-20°c I meant. And this was published almost a decade ago, so today's TEG modules could be more efficient.

[Opinion Owner]

You may be too busy getting worshipped, but once you get time, consider that my ultra accurate research program found chinese thermoelectric generator modules costing under 5$ per 72 watt. Actually less but it's better to overestimate. For $1,000 that would be 14.4 Kw, while a 1,000 dollar solar panel is only 2Kw,
So then with a minimum gradient of 20°c it will equal constant 1.15Kw that operates 24/7. Ending with 28kwh per day. I forgot our price, in some counties it is 20 cents per kwh, so you get almost 6$ per day. To pay off, it will take 167 days.

A solar panel rated 2kw would give 7kwh per day assuming the irradience is average. It will take 4 times longer to pay off, 668 days, which is 22 months.

[Opinion Owner]

In the main opinion I was referring to our scrotums.
@lliam what do you think of the idea to generate power geothermally?

As I laid out and I hope the math is correct, even with a small difference of 20 degrees you will get paid out what you invested 4 times faster than with solar panels. Plus it takes less space, you don't have to fill up your who backyard or rooftops, and you can use it immediately wired to the home, as opposed to needing to store in batteries.

Hey.. I might do it this winter, the septic is warm even in winter. But do you think it's a bad idea, as drawing heat from there will cause the septic system to freeze? Or is it well warmed by the surrounding soil?
There's probably a reason people heavily insulate their skeptics so no, unless I have a specially deep one, not an option.

[Opinion Owner]

Quoting a random website,

A mid-ranged domestic turbine of 5 kW can provide around 8,000 kWh to 9,000 kWh of energy per year under the right conditions. Smaller turbines of around 2 kW can have an electricity generation of up to 3,000 kWh.

So first of all buying the 2kw turbine, just the generator will exceed 1,000 dollars.

Then, they expect 2kw one to produce 3k/365= 8kwh per day. About the same as solar.

[Opinion Owner]

Hard to find info. Even when the temperature difference equals the same amount, I assume it matters whether it's 200-220 or 0-20.

So even if the production in winter is 0 (maybe it isn't)
In summer they will beat solar panels.
I'm now having trouble with the pricing. The document stated that the module that performed the best, costed 3.4 usd per 500w capacity. Let me reread.

[Opinion Owner]

@Dildорhobe FUCK YOU I was they posted the abstract of one experiment and the documents attached to it of another. So 3.4 usd module only gave them 4.5 watt at higher temperature. This is all useless and the above numbers are wrong.
