babypolis posted:my friend had the same idea with the solar panels and the parking thing except he added you could use the blocking of the panels to tell which spaces are occupied, an incredibly cost efficient measure that would surely make up for how dumb everything else is The thing is, solar panels in parking lots is actually a good idea.  It's just that the idea's already been perfected and your friend is an idiot.

i would think that the fancy strong glass they use for the panel would provide less traction than asphalt unless you scored the glass which would probably reduce the efficiency of the power collection better to just put panels on all the roofs imo

TheJoker138 posted:Wouldn't it at least be quicker to fix these roads? One of the panels gets super hosed up, you just take it out and slot in a new one? I'm sure it would be insanely expensive, though. yeah brick and cobblestone roads are already inefficient from a cost perspective and those are made from literal mud and rocks. they only get used for vanity applications and in most of the places around here that have brick roads you're not allowed to park on them or in some cases drive on them the quickest way to fix a road is just pour fixer sludge into the hole instead of tearing up and replacing broken parts

I'm Crap posted:I keep seeing people say this but I have no idea where they're getting those numbers. Here in Northern Europe, total yearly insolation is something like 900kWh/m2. If you could convert that to electricity at 15% efficiency (and you can't) that's 135 kWh/year/m2, which would be worth about €10.80 per m2/year at €0.08/kWh. 25 * 10.8 = a lot less than the price of a square meter of solar panels, let alone installation and the grid-tie equipment. Lorfo at them lasting 25 years too, they start conspicuously losing efficiency after about 5 no matter how clean you keep them. The good panels come with a 20 year guarantee for still generating 80% of their rated power. Overall you are looking at about €1-1.50 per Watt peak which should generate about 0.85KwH per watt peak per year. So at €1.50 per KwH peak and 0.85 KwH generated per year at a value of €0,08 you would probably not make much money (about 20 years to pay off the panels + inverters). Of course if the panels and inverters don't completely break down, 50% of rated power after you've paid the panels off is stil in essence free power. Of course i don't pay €0,08 per KwH but more like €0,22 so you get a ROI in 7 years. This is the case for multiple countries, even in Northern Europe (Germany, Netherlands, Denmark, Belgium, UK). In Germany or Denmark you could earn the cost of the array back in 5 years. I would say in Europe your prices are exceptionally low and not at all the norm (Norway or Iceland i guess?).

this might work in the midwest where the weather is boring and there aren't many people around but I can't see this working in big cities e: ofc the wonderful thing about electricity generation is that you can send it anywhere so maybe only doing the midwest would be enough??? idk i'm not a civil engineer or w/e President Ark fucked around with this message at 19:02 on May 29, 2014 |

wasn't there some plan to do something w/ kilometers long solar panels in space and i guess through magic the energy would be sent down to earth? or no wait i think it was something like you'd use a big mirror to keep the sun shining on the middle of nowhere in the desert 24/7 so a few miles of solar panels would always be charged

A Buttery Pastry posted:Looking it up, the cost of electricity is around €0.3 per kWh here in Denmark, so yeah, that's going to make a difference. Solar is still a dumb thing to focus on over wind (and nuclear) though. No reason can't do both. Advantage of residential solar power is that the investment is provided by households themselves. People are putting up PV arrays simply because they make the calculation and figure it offers a better return than a savings account. Nuclear, wind, solar, we need it all.

I would say in Europe your prices are exceptionally low and not at all the norm (Norway or Iceland i guess?). I hadn't realised how cheap the panels had gotten, though. I'm still pretty dubious about the retailer's claims for practical yield in the arse climate we have up here, which appear to be done on the basis of total solar irradiance times peak efficiency, not taking into account the fact that on a lovely overcast day like today there isn't enough sunlight to let the panel function properly. But if the price keeps tumbling the way it has in the last ten years or so, that might stop mattering soon enough. What the world really needs is a scheme where I could buy solar panels for some dude in Greece to stick on his roof and I could credited for the power generated from that, instead of having to put them up on my own roof in order to get rained on a lot and basically not see the sun at all between about October and February.

I'm Crap posted:€0,08 to €0,10/kWh is about what retail electricity costs everywhere in mainland Europe without VAT and, more crucially, without feed-in tariffs designed specifically to vastly privilege solar over every other form of power generation, even the more practical ones, and which, in effect, act as a really punitive regressive tax on all electricity consumers, in order to benefit Al Gore types with solar panels on the roofs of their big detached houses. This is all true. But if you are a privileged person with a detached house (for which you receive massive tax breaks) and a electric car (that is pretty much free after tax incentives) you would be crazy not to take advantage of this massive opportunity the powers that be have created for you that is not going away any time soon. What is privilege if you don't take advantage of it? e: What matters to people is that this is a way for them to reduce energy costs, if things were fair costs would be lower to begin with, but they are not.

I wish electric cars were free here after tax breaks but the tax break is only like 7500 dollars. I guess that'll pay for replacing all the batteries in 5 years.

I love the video where they're carefully driving a balloon-tired tractor back and forth over it. Great, it will hold up to gentle, normal driving by rubber-tired vehicles. Now will it hold up to a 777 making a blown-tire emergency landing at 130mph on it? How about an inadvertent grader blade or oil spill or explosion or chemical fire or bee-truck overturn? How will it hold up to flooding of the wire-canals from all that snow you're melting on top of it?

Here's my idea. Currently leveling the grid load is more important than renewables. Time shifting power. Think Raccoon Mountain Pumped Storage. Unfortunately there just aren't enough mountain tops to build reservoirs on. Solution? Giant Fly Wheels. Like really giant. Thousands of tons. Build them rights outside of major cities. Get them spinning at tens of thousands RPM when there is excess power production and generate energy off of it at peak hours. Nothing can go wrong!
