Green Energy

An idiotic idea which will go nowhere just the one about putting PV modules on road surfaces was.

have we run out of convenient places to put panels? that's news to me, last i checked we still had a hilarious amount of free roof space and stuff like parking lots where we can just slap up the panels.

i think they'll crack from the vibrations, or to avoid that they'll need to be built a lot sturdier than normal.

In which case just make the cheap version put them on top of buildings, in cities, near to demand; like everyone with a quarter of a brain has known since their invention.

Don't install sensitive/ fragile equiipment in dangerous places near massive energetic machines uness it's neccesay for those machines or there is really no where else to put it.

Can I get 60 grand to shove a solar panel up my arse as an "experiment"? Maybe some of these dumb experiments will help figure out a way to manage all the challenges of idiots who have more money than sense - that might be worth it.

Even if not between the tracks, aside the tracks there is quite a bit of empty space. That space gets a lot less of a hard time from the trains rolling by

Also, costing €623,000 over three years sounds rather expensive for just 100m

It's hugely expensive, but I expect most of the cost to be in the wagon that lays panels down and picks them up - and could hopefully service a big stretch of railway (if it works). That kind of systems will cost a pretty big penny.

I doubt if this project will "fly", however. A totally horizontal solar panel at ground level is a far cry from producing energy efficiently.

What’s the plan for when people start stealing the solar panels? Good luck trying to stop people

A lot of the comments here are, pretty fairly, sceptical of whether this is a viable idea.

My question is, what's the advantage meant to be over just having an electrical railway and seperately some solar panels plugged into the grid? Especially since the article mentions the solar railway would be grid connected?

Wouldn't it be better to place panels on the train roofs?

As always with these fancy ideas it is a solution for something that is not a problem: We aren't even close to running out of suitable space to put solar panels. The problems for solar are usually just willingness, bureaucracy, or the electrical grid not being able to handle the additional load.

We've also had proposals for solar bricks for paving roads/parking lots, putting the panels as dividers between highway roads. It just doesn't make sense to overcomplicate things.

Come back once every single parking lot, large roof, unused radom patch of land, or even agricultural land (there are some interesting setups where the shade provided by solar panels is actually beneficial for the plants) is fully utilized. But chances are that at that point we already have more than enough capacity.

These people can get fucked. Everyone can get fucked. We don't need new ideas we need old ones.

We need the market to be able to react. Being able to build on land, fuck the NIMBYs. And being able to connect to the grid quickly, there is different ways to sort this but it comes from government intervention.

Then if you want more progress it's externalities. Tax fossil fuels and use the same money to subsidise renewables and batteries, and grid upgrades.

Or another possibility is mandate shutdowns based on a percentage over time (this will work better for EVs I think than than utility power. "Oh you want tariff on Chinese cars. Well fine you will have that for 10 years and in return 100% of your sales need to be evs in 10 years and to get you moving in 5 years its 25%, 6 40%, 7 55%, 8 70%, 9 75%.")

It's getting so tiring now that they have evidence of what works and instead just talk about how the worlds going to be different in 2050. Start building some fucking grid upgrades then. You know it is going to take 10 years tondo anything meaningful, you know you are 10 years behind, you know if you build it they will come.

Covered Highways. The benefits of additional PV and the benefits less rain and less sun glare on drivers. You could also install a tram like wires above in one lane for maintaining the EV charge on trucks and buses.
