Eternal is gonna be much more reliable than me or this post xd
Some sources of power are cleaner than others, and with global warming on the rise where we get our power from becomes more of an issue that needs to be addressed.
Renewables:
Pro: - Less/No CO2 and other gases that cause global warming
Con:- Current infrastructure is not based upon this. it would take a lot of money and effort to switch and make sure people aren't cut-off during the transition.
Wind:Â Wind power can be harnessed using wind turbines either on land or out at sea.
Pros:- Wind will be something that is around as long as the earth is.
- Cheap source of renewable energy.
Cons:- Can be noisy. so must be placed a certain distance from homes or where people will be a lot of the time.
- Wind is unreliable, it can stop/start suddenly.
Solar:  Solar power is gathered from sunlight by panels.
Pros:- Can be put in many places, e.g. on roofs of houses which would've had nothing on before.
- Silent.
- The sun will keep going for billions of years.
Cons:- A cloud can stop you getting power. (Not reliable).
- The time of year heavily affects power gain. (less in winter, where you might want more power)
- Expensive.
Geothermal:Â Â Geothermal power is gained from the heat of the earth.
Pros:- Reliable.
- Generates a lot of electricity per unit spent, as running costs are very low.
Cons:- High start-up cost.
- Has to be placed in a location which will allow for it.
Hydro:Â Wave power is generated by big dams in the sea, using the moon's pull on the Earth to generate power.
Pros:- Reliable cycle. The moon's gravitation pull provides a set timing for when waves go up or down.
- Efficient, a lot of power from the waves is turned into electricity
Cons:- Really hard to place, you need a really specific place to put one of these.
- If you don't plan it well, it could cause rivers to dry up downstream or flooding upstream, disrupting people's lives.
Non-Renewables:
Nuclear: Nuclear power uses radioactive decay to generate a lot of power
Pros:- Lasts a long time, although not renewable it lasts a while.
- Current infrastructure uses nuclear and we have a lot of data on it and its effectiveness in real situations.
Cons:- Has to be maintained VERY WELL. If this goes wrong, nuclear meltdown is extremely bad.
- Removal of waste must be done properly and securely, or radioactive material may end up getting where it shouldn't.
Coal: Coal power has been used for centuries as a main source.
Pros:- Existing Infrastructure.
- Cheap.
Cons:- Extremely Dirty for the environment, loads of emissions.
- Acid Rain and other unpleasant things.
I may have missed some out and if you think any of the points are wrong say in a post and I will see if I need to change it.
I think that renewable power is definitely the way to go as we need to really focus on lowering our emissions, nuclear can help with the transition as it's less bad than the other non-renewables but must be maintained well.

- What are your opinions on self-driving cars, any pros and cons?
- How fast do you think they should/would be implemented if at all?
- What do you as the risks involved and how do you think they should they be managed?
- Moral/Ethical Dilemmas?
----
- I think we should have self-driving cars as machines don't make human errors, get drunk, etc. and so they'll be safer and prevent injuries and deaths especially when a lot of the cars on the road are self-driving.
- They should be tested well first however, but governments should allow more of this testing and encourage it. The self-driving cars shouldn't be rushed out ASAP without proper tests or analysis of the two points below.
- Risks involved include the fact that since the car would be automated, there needs to be checks against malicious code and manual overrides for different scenarios such as opening the doors (so someone can't trap you in with a virus).
- The toughest part in all of this imo is the moral/ethical dilemmas, that would have to be heavily analysed and be as fair as possible. I'm not good at this kinda stuff so I can't really have a good/strong opinion on this one.

Is it possible to find a sim page that doesn't give the third-party website message? I've been stuck using 4 separate windows from pr2hub.com and it gets a lot more lag and problems than if I can have 4 pr2 windows on the same tab...

| PR2 Level Editor Problem |

Hello users. I'm J m i and i want to explain a problem that i've found about the level editor. I could find this issue months / year ago but back then it wasn't a real problem as i've never done "long levels" with a lot of art on it, but on this case, i've created a long one so i had to draw a lot of BG (background) on it. I've talked with Bls and with other users like Vasalemma and they can confirm it, but i found it better to publish the issue over here so the community can judge/ write about it on here as well.
I will try to short it:
Problem:Â level editor has "low" art data? so it doesn't allow to paint as much as you need to.
Type of problem: Probably server issue? Probably the game doesn't support a lot of art per levels (Although thinking about this, that would be normal too as there are a lot of players and it would be a waste of memory if everyone draws a lot on every level that we create...  )
Expected behavior:Â Let player use more art on levels without level art being bugged.
Actual behavior:Â When you "use up a whole art", level got bugged so some ART parts of your level will be pixelated and bugged... So art can be destroyed and you can't even do nothing to fix this.
Steps to reproduce the problem: Just create a long map (not even neccesary) and draw a lot on it. Save the project so you will see level starts to be slower when you save or load it, and then when you draw in some other parts, the first draws will be destroyed (disappear or pixelated as i mentioned before)
Additional Information: It would be good, like an idea i can suggest, that IF ADMINS CAN'T increase the art/ draw memory of game (or whatever it controls it), THEN there should be a button to be able to DELETE ALL THE DRAWS ON THE LEVEL OR at least the data from that level (in 3D sofwares you can "delete all by type story" so it's like you free some kind of memory...

| PR2 v155: Artifact Fairness |

This update provides fairer mechanics for winning the artifact prizes.
Changes/Additions
- New artifact mechanics
- Changed the Jigg Hat obtain message in part listing from part popup
Fixes
- Hopefully fixes random disconnects (increased time needed before socket server timeout)
- Context (right-click) menu is now correctly hidden
Here are the new mechanics for obtaining the artifact first:
- If the first finder doesn't have bubbles, then they get the bubbles as normal
- If the first finder has bubbles, the finder gets 10,000 EXP as a consolation prize
- If the artifact has already been found but the bubbles haven't been claimed, the bubbles go to the first person to find the artifact that doesn't already have bubbles
This can't really be tested privately without affecting the public servers, so I just pushed this straight to the server and skipped the beta testing phase. If you encounter any problems, please let me know!
