These are ten most promising alternative energy sources of tomorrow.

It’s a really exciting time to be alive. We have a front row seat to the only known transformation of a world powered by dirty fossil fuels, to a planet that gets its energy from renewable, clean sources. It’s happening just once, right now.

Dear scientists
I'm taking my hat off to you,gentlemen.
Jim Agnew
Think of it like the old water WHEEL corn grinders. But instead of water, it's replaced with drop weights.
Jim Agnew
Hydraulic pumps can as be used to pump water, hydraulic power is powerful at 2500 p,s,I, to 3000 p,s,I, which can be harnessed in many ways. So much more torque than electricity, and less expensive, with less maintenance.
Jim Agnew
A power source can be created if a person had the land and the money? Build a reinforced concrete flywheel around 200 feet tall, around 25 feet or so wide around 20 feet thick with large I beams for spokes attached to a huge axle mounted on huge plaster footings, build slide weights that will slide up and down on the I beams spokes, allow them to go up and out at one o'clock to 6 o'clock , retract them from 6 o'clock to 12 o'clock, the counter weighs will have to be around 40or 50 tons each, mounded to 12 spokes, may need a pony motor to start the rotation, can be started on its own, but will take longer to get going, To harness the power, a ring can be placed on the outside 0f the flywheel, one on each side, mount a low profile heavy equipment tire mounted on a axle to a large trunk transmission turned around backwards, where the gears can be changed, by mounting the transmission this way it will be like a overdrive, hooked to a hydraulic pump plumbed with hard lines to a heavy equipment hydraulic pump, adapted to a heavy equipment transmission turned around backwards to up the gear ratios, then hook it up to a electric generator which can be geared by charging the gears in the transmission, the torque will be well enough and will be hard to stop. More than one set of tires can be used to harness even more power to other generators, no cost to operate except for maintenance, have been thinking about this for years and can not get it off of my mind, this is the first time that I have ever had the opportunity to bring this up to people like you all, thank you all for your patience and time. It was all just a thought. Thanks.

The World Health Organization has studied and found that current nuclear generation is the SAFEST form of producing electricity, including statistics from Fukushima and Chernobyl. Think of how safe newer advanced designs like Molten Salt Reactors will be! Carbon free, base-load generation, and we can do it.....right now.....what could be better?
Sjaak Schulteis
What has become of it since 2014?
ItonicGaming
where are we at now?
Jonathan Wells
Useful video. I like the fusion, like the thorium reactor and recycled old nuclear instead of storing it. I have solar and I like tidal and wind. The excess power can be stored in liquid salts, hydroelectric storage for night generation or hydrogen fuel cells for use in airplanes and night time power grid energy use.
tadeu, antonio Passarelli
Mr. TESLA created the wireless energy transport..Where is it?
Anthony Townsend
Global Warming is a global bankster taxation scam. Turn off MSM and research yourself.
david mccallum
There is already multiples of light speed by superluminal craft, using thought by symbiotic interface. Distances to 88 light years.
Wind is a complete scam, and solar not much better while subsidised. Both low density generation. The deep state already has the box, and uses a tokomac cold fusion reactor. There are multiple nations repeating the same process very slowly. Lockheed is not interested in bringing these into the public realm. The military industrial complex is some 1,000 years ahead of the public. Ever listen to Ben Rich ? How about Col Tom Beardon ? Perhaps David Sereda ? And there are others.
Helium 3 mining on the moon, bases on Mars under terraforming as is earth by geoengineering that destroys organic food allowing GMO to flourish and using a combination of other means, to alter DNA. of the masses.
Peter Brorsson
What about creating energy using crappy comments! Where's my Nobel price? For certain, it's an unlimited resource...

pyrolysis.. solves garbage problems, can generate by products and energy.

Oh dear, gross misunderstanding of fast nuclear reactors.

Forgot to mention the hydrogen storage sucks. IT'S NOT JUST COSTS.

EDIT: YES, NICKEL-CADMIUM BATTERIES ARE RECHARGEABLE. I GOT THAT WRONG. THANK YOU TO THE 1,000 PEOPLE WHO HAVE CORRECTED ME. I SHALL WHIP MYSELF IN PENANCE NOW.

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?

Transcript:

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.
