There are sooo many more things that need to be expounded on that will change the way we harvest energy. We already have several that work right now. Unfortunately w/the way the global economy is structured by introducing just one on a mass scale would distablize entire regions so it is also about bringing all this technology into the world & creating a paradigm shift in both economic practices & mass energy sources. I won't go into more on this platform, but if you dig deep enough you'll find that which has been hidden in plain sight & methods of producing clean cheap or free energy that has already been implemented & used, but kept in the shadows to the common person for decades.

Nuclear produces around 600 MW per hour per reactor , Oyster @2:25 produces 2.4MW , Hydrogen is worse than CO2 and highly flamible, Geothermal heat @4:35 great depands where you live and it may allow a hot bath, but be prepared, it comes with a huge cost to the environment, Nuclear waste, another massive cost, solar panels 100% way forward but reduce the output in your house, Bio fuels, lets say you had a farm, try using it in your tractor and see if the Government allow it, Wind farms (Turbines) need power so are useless, what the problem is there is to many people and Cities to feed, it will onlt get worse.

Alternative energy means paying china to make panels whilst the panels use 2.5 times more coal to make the panels over their entire life time than it takes to just BURN COAL... why do we need to give them jobs and make their rich people richer whilst they have 1.2 billion poor people earning $250 a month working 12 hours days 6-7 days a week...??? piss off alternative Communist energy.... Socialists suck weener.

LOL Space X ever becoming cheaper LOL What a crock of hard sell advertising this crap is... Solar isnt even marketable at 46% efficient yet and Coal is at 40% and getting cheaper in 2 years time as well as more 98%efficient hydro plants.... gee
Leslie Grayson
LOL space based power LOL

They missed magical energy. Its Magic!!!!!!!!!! you can do anything you want with it ^_^

This video should have stopped after it listed the number one source of energy in the future ... fusion. Energy sources 2 through 10 all have one and the same problem, they are rediculously expensive and can only be utilized by forcing people to pay vastly more for energy than for conventional energy. This would result in massive decreases in the quality of live for all people. Only fusion power offers the promise of virtually free, clean, and non polluting energy. Advances in fusion power development mean that fusion power generation will be a reality within the next decade. Twenty years from now the world will be dotted with dozens of fusion power plants producing essentially free electricity and transforming the world in the process. Previously uneconomic industrial processes, such as water desalinization, will become cheap and easily doable once electricity becomes free.

The flip side of free electricity produced from fusion is that virtually every other energy source will not be able to compete. Twenty years from now the world will be dotted with the rotting hulks of hundreds of thousands of windmills, solar farms, and other green energy boondoggles that produce fine electricity but at a price 1000 times higher than the price of fusion electricity. 100% of the hundreds of billions of dollars invested in green energy boondoggles will eventually be written off as the price of maintaining windmills and solar farms becomes more than the electricity can be sold for. They will be abandoned to rot and will serve as constant reminders of the foolishness of government mandated technology development.

Fortunately for the world at large, free fusion energy also means that nobody will want to generate electricity from oil, coal, or gas anymore. All carbon based electrical generation will cease almost overnight as soon as fusion power plants come on line. Electric cars will rule as they will be almost free to operate. The only place that oil will continue to be utilized is for lubrication and for specialty applications such as airplanes and ships that do not lend themselves to using fusion generated electricity.

100 years ago the world converted from using horses for transportion to cars within a decade. There was no massive government program to convert from horses to cars. 30 years ago the world converted from analog computation to digital computers within less than a decade. Again, no massive program to force technological change. The moral is that when the economics are there then massive change can occur. The time is right for the change to fusion power.

Ok, this is great but when you say sustainable do you mean also for the land and the people around that land where you are building these new energy sources? Sustainable for who Amerikkka or is it going to require continuous exploitation and colonization of the global south?

We could harvest static electricity from our pavements our pavement could be made of copper/nylon pressure mats which when compressed create static electricity which could then be directed into a huge battery underneath the road which also picks up the static electricity from the pressure inflicted upon the road from the traffic cars vans lorries etc . I haven't really lookedattheproblemproperly yetthisideais justoffofmy head and needs a little tweeking but it's workable

Don’t for Thorium.

We need to put the Big Oil Borons on trail for suppressing these technologies.

Wireless beaming of Solar energy is a waste of time trying to develop at this time as we have transmission lines to do that and innovation does not come before its time!

Graphene Supercapacitors Are About To Change Top 10 Energy Sources of the Future 9 months ago   09:18


We live our lives through portable devices, and the race is on to create better energy storage for those devices. Could graphene supercapacitors be the holy grail?

Ted-Ed, how batteries work

BASF Lithium Ion

Impossible Battery - Seeker



So before I can explain how super capacitors will fix this, let’s back up and explain how batteries work in the first place.

To make it simple, batteries work by moving electrons from a negatively charged material called an anode to a positively charged material called the cathode, and the device siphons off those electrons to power the device.

For instance, nickel cadmium batteries use a nickel oxide cathode and a cadmium anode. Hence the name.

This is a chemical process called oxidation that involves an electrolyte layer sandwiched between the electrodes.

In the case of the nickel cadmium batteries, they use potassium hydroxide as the electrolyte.

But this is a one-shot deal. The chemical reaction releases the electrons, but there’s no way to re-introduce electrons into the equation.

So they’re not rechargeable. And for a world increasingly reliant on portable devices, that’s just not good enough.

Enter Lithium-Ion batteries, which were developed in the 1970’s by John B. Goodenough. That’s his real name. That’s not a joke.

Lithium ion batteries have a cathode made of lithium, duh, and an anode made of carbon, again with an electrolyte between the layers to facilitate the reaction.

The difference is lithium will absorb more electrons, so it can be recharged. But it is still a chemical reaction, so it can only reintroduce those electrons at a certain charge rate.

Super capacitors work differently. Instead of using a chemical reaction to make electrons flow, also called and electrochemical process, they use static electricity, or an electrostatic process.

Now, capacitors have been in our computers for decades, and they work by holding opposite charges between two metallic plates separated by a dielectric material.

Super capacitors, as you may have already figured out, are larger versions of capacitors that use a double layer to hold more energy. In fact they’re sometimes called double-layer capacitors.

And the cool thing about them is that since the electricity is static and not chemical, there’s far less resistance to the charge. In fact, it’s almost instantaneous.

The problem is, they don’t hold that much energy. You need a vast amount of surface area to hold enough energy to make them really useful.

So Lithium Ion batteries are very energy dense, meaning they hold a lot more stored energy, but super capacitors are very power dense, meaning the transfer the energy much faster.

If, theoretically, you could create super capacitors that could hold as much as a lithium ion battery, you’d have cell phones that could recharge in seconds and it would be good for the rest of the day.

And dare we dream it? An EV car that fully charges faster than it takes to pump gas.

There is one material that could make this dream a reality. It’s called graphene.

Graphene is basically a one-atom thick lattice of carbon atoms that has some ridiculous properties. It’s 200 times stronger than steel, but incredibly light, biodegradable, biocompatible, meaning it can be used in the human body.

They say it can be used to desalinate sea water, make space elevators, and form the basis for supercomputers, but for our purposes, it also happens to be one of the most electrically capacitive substances known to man.

It has the same energy density as lithium ion batteries with the power density of super capacitors. And since it’s only one atom thick, you can pack a ton of surface area into a small space.

With any luck, in the next 10-15 years, we’ll have super capacitor batteries that can handle energy densities at industrial scales giving us quick, plentiful electricity whenever we need it.
