How to help the world?

Petroleum, can be replaced. The most promising is nano metal particles. That are 100% recyclable. Only modification is to the exhaust system to capture them, so they can be re-used.

Stop scaremongering. There's plenty of fuel alternatives that can and will be used.

What is the muhabee desert.

24hours light would supply the total energy needs of the world for 1 year?

Your the same as ever other scaremongering. you forget we are resourceful and inventive. Most of the technology we need is already invented. It's just not economical at the moment.

You haven't even taken into account using heat transfer units and wind turbines on every new house and grants to retro fit old houses.

believe me power is not a problem.

Look, you take small scale examples of energy capture and extrapolate them and assume they will supply all the energy we need. 24 hours light would supply the world for a day...what of it? We cannot capture even 1 billionth of the light that falls on the earth in a day, so how can you even suggest that as a potential energy panacea? So a billion days light capture will supply us with energy for 365. Great.
You have no data to back up your beliefs!

Worlds largest photovoltaic plant? Poking in Bavaria. 75000 square metres supplying 3300 homes. 20 million homes in the uk, so you need 6060*75000 square metres i.e 4500 square kilometres of solar panels. That's a quarter of the surface of Wales mate, just to make electricity using panels which we don't have because they are too expensive and use too much natural resources to make (a 1kg panel needs minimum 10kg of oil and 100kg of purified water to make).
 

Using population percentage to scale up your requirement for nuclear power stations is completely flawed (as I'm sure you well know). It would be fine if every single person on the planet used as much energy as your average UK citizen, but they don't.

You've also completely sidelined nuclear power due to the reliance on U235 that traditional burner reactors have, yet the technology exists to build fast/thermal breeders which both avoid that dilemma in different ways. We also can't predict exactly when the breakthrough will occur with fusion technology, that finally sees it produce more power than is fed into the reactor.

The alternatives might not be able to replace petroleum+coal in the current economic and technical climate, but I have no doubt that they will be able to before those resources are depleted or become unviable.

Panels are expensive and rubbish at large scale solar farms. 1/4 the size of wales is easy. You realise how big these deserts are?

Go read up on technology and suggested plans. There's loads out there. Or you can sit back and believe in doom and gloom.

Don't let facts get in his way of scaremongering, where all doomed I tell thee.
 
Focusing on Europe, North Africa and the Middle East, they say, Europe should build a new high-voltage direct current electricity grid to allow the easy, efficient transport of electricity from a variety of alternative sources. Britain could put in wind power, Norway hydro, and central Europe biomass and geo-thermal. Together the region could provide all its electricity needs by 2050 with barely any fossil fuels and no nuclear power. This would allow a 70% reduction in carbon dioxide emissions from electricity production over the period.

The paragraph you quoted on solar power is a little out of date. It relies on modern Stirling engines, as they are more efficient than solar panels that are currently available in bulk. However, there are experimental solar panels that are more efficient than Stirling engines, so the amount of electricity that can be supplied by solar power from North Africa is greater than the figure you quoted.
On the other hand, the Stirling engines are easier to mass produce and would do the job more than well enough.

The next problem would be transmission from Africa to the whole of Europe...but the Canadians solved that problem decades ago for the simple reason that the size of Canada made it necessary. Transmission losses wouldn't be a problem.

The problem is that building the system in the first place would be monumentally expensive and require the co-operation of a couple of dozen countries.

The amount of energy that reaches the surface of the Earth from Sol is more than 10,000 times the total energy consumption of the entire human race. Converting 0.0001% of it to electricity shouldn't destroy the Earth's ecosystem.

Strictly speaking, it is a non-renewable resource, but output at the current level is expected to be sustained for a few billion more years and when it fails everything on Earth is going to die anyway.
 

As you say networking the electricity isn't a problem. The construction can be done in phases or perhaps a sustained growth.

The biggest problem as you say is cooperation. But as the Eu expands and oil gets more expensive. It's in everyones interest. especially as a by product is fresh water for nearby africa. As well as the income generated by selling the power.

As another source of energy, we have a lot of hydrogen and a method of extracting it from water such that burning the resulting hydrogen yields 144% of the total energy required to extract the hydrogen, i.e. it's viable. Experimental at the moment, but it demonstrates that it's a feasible method.

To paraphrase Granny Weatherwax, we ain't dead yet.
 
I need to up this thread because the search engine returned it and it fits the best what I wanna share. Something very exciting :eek:

Woman raises £190k for homeless man who gave her his last £15
https://www.msn.com/en-gb/news/worl...her-gas/ar-BBFyOt3?li=AAmiR2Z&ocid=spartanntp

The story is:

Kate McClure was on her way to Philadelphia when she met Johnny Bobbitt Jr.

He is a homeless man. But at that moment, she was the one in need of help.

McClure ran out of gas while driving on Interstate 95 last month. She stopped at the nearest exit ramp, her heart pounding as she got out of the car to find a gas station, she said.

Then she met Bobbitt, who was sitting on the side of the road near the exit ramp holding a sign.

“He saw me pull over and knew something was wrong,” McClure recalled. “He told me to get back in the car and lock the doors.”

McClure said Bobbitt walked to a gas station and came back with a can filled with gas. He had spent $20 — the only money he had — to buy it.

McClure decided to give back, so she started a GoFundMe campaign about two weeks ago to raise money to help Bobbitt get back on his feet. She had intended to raise $10,000 to pay for an apartment, a vehicle and other expenses for the next four to six months.
She has raised more than $252,000 as of Thursday afternoon.

The Washington Post was unable to reach McClure on Thursday, but she talked about her chance meeting with Bobbitt on the GoFundMe page.

“Johnny did not ask me for a dollar, and I couldn’t repay him at that moment because I didn’t have any cash,” she wrote.

She said she has been driving back to Bobbitt’s spot over the past few weeks, giving him a few dollars every time. She also repaid him, gave him a jacket, gloves, a hat and socks.

“One day I stopped to see him and had a few things in a bag to give him, one of which was a box of cereal bars so he could have something that he could carry around and eat,” McClure wrote. “He was very appreciative as usual and the first thing he said was, ‘Do you want one?’ ”

Another day, McClure said she gave Bobbitt two gift cards from the Wawa convenience store and a case of water. In response, Bobbitt, according to McClure, said he couldn’t wait to show “the guys” what she had just brought him, referring to a couple of friends he hangs out with.

“If those 2 statements alone do not give you a glimpse of the good heart this man has, I’m not sure anything will,” McClure said.

Bobbitt, who’s from North Carolina, became homeless because of problems with drugs and money, the Philadelphia Inquirer reported. The 34-year-old has been living on the streets for a year and a half.

Public records show arrests in North Carolina dating back to 2001.

The Post called a number registered under the names of Bobbitt’s relatives in Henderson, N.C., more than 40 miles northeast of Raleigh. A man who answered said they “do not want to make a comment at this time. I’m sure you’d respect our privacy.”

A Facebook page that appears to belong to Bobbitt has not been updated for more than a year. Three-year-old photos portray a man who seemed to be, at one point, living happily with a significant other and their dogs. One picture from June 2014 shows a clean-shaven Bobbitt smiling next to a woman wearing a pink and white long-sleeve blouse and a dog.

McClure and her boyfriend, Mark D’Amico, told the Inquirer that they have gotten to know Bobbitt over the past weeks.

D’Amico said Bobbitt had talked to them about how his life took a turn for the worse.

“Johnny said, ‘Yeah, tell me about bad luck. But don’t get me wrong. I’m here because of my own decisions. I got nobody to blame but myself,’ ” D’Amico told the Inquirer, adding later: “He knows where he’s at and he knows what he has to do to dig himself out.”

McClure wrote on the GoFundMe page that she believes Bobbitt is driven to find a job.

“I believe that with a place to be able to clean up every night and get a good night’s sleep, his life can get back to normal,” she wrote. “Truly believe that all Johnny needs is one little break.”

Just before Thanksgiving, McClure shared an update on Bobbitt. She said she and her boyfriend had found a hotel where Bobbitt can stay for the holiday weekend while they work on finding him a permanent home.
 
Offer to do some work at the local charities? Can't think of much else, i've tried to do this in the past and unless you're willing to commit to 'x' amount of hours a week they don't tend to want to know.

Edit: Er, sound necro.
 
I think that children should be taught meta-ethics, descriptive ethics, normative ethics and applied ethics in school and all the time.

https://en.wikipedia.org/wiki/Meta-ethics

Meta-ethics is the branch of ethics that seeks to understand the nature of ethical properties, statements, attitudes, and judgments. Meta-ethics is one of the four branches of ethics generally recognized by philosophers, the others being descriptive ethics, normative ethics and applied ethics.

While normative ethics addresses such questions as "What should I do?", thus endorsing some ethical evaluations and rejecting others, meta-ethics addresses questions such as "What is goodness?" and "How can we tell what is good from what is bad?", seeking to understand the nature of ethical properties and evaluations.

Some theorists argue that a metaphysical account of morality is necessary for the proper evaluation of actual moral theories and for making practical moral decisions; others reason from opposite premises and suggest that we must impart ideas of moral intuition onto proper action before we can give a proper account of morality's metaphysics.

https://en.wikipedia.org/wiki/Applied_ethics

Applied ethics is the branch of ethics concerned with the analysis of particular moral issues in private and public life.[1] For example, the bioethics community is concerned with identifying the correct approach to moral issues in the life sciences, such as euthanasia, the allocation of scarce health resources, or the use of human embryos in research.[2][3][4] Environmental ethics is concerned with ecological issues such as the responsibility of government and corporations to clean up pollution.[5] Business ethics includes questions regarding the duties or duty of 'whistleblowers' to the general public or to their loyalty to their employers.[6] Applied ethics is distinguished from normative ethics, which concerns standards for right and wrong behavior, and from meta-ethics, which concerns the nature of ethical properties, statements, attitudes, and judgments.[7]

An emerging typology for applied ethics[8] uses six domains to help improve organizations and social issues at the national and global level:
