The Solar Window Of Opportunity: Joe Jordan at TEDxSantaCruz

[@lukaszs727]

Ive watched many TED videos on youtube but this guy is the most charismatic Ive seen so far!

[@Veganoshka]

Thanks Joe and sorry I didn’t watch this earlier! ❤ still so relevant.

[@NickalusNicoJohnson]

Joe Jordan, you're still one of my heroes. Thank you.

[@ffmedic95073]

Great Job Joe!! Very enjoyable.

[@stompbuilds5416]

Loved the talk Joe!

[@ciceroaraujo5183]

really nice teacher

[@kleinepop]

awesome! thanks Joe!

[@slvbackyard]

Hi Joe: This is a very timely, well done reminder of what we need to be doing. Fred

[@Brainbuster]

Play at 1.25x playback speed. ;)

[@sjlams1]

Very informative and entertaining!

[@Gvb6]

Massive respect!

[@kazizulkader]

if we move away from fossil fuels to solar (and other alternate) energy, it can also bring an end to war and strife. The rich nations wont be running after the oil and trying to dominate over foreign lands. It will also make each one of us self sufficient and bring greater love and happiness in the world. Wonderful presentation Joe. Let the sun reign, and bring us more brightness and joy as it has for millions of years.

[@rexv16]

Beautiful!

[@Plutobolic]

Good job joe .....start the revolution !!!

[@lucascantin191]

I can't believe the trolls. His talk is common sense. Their attempts to discredit him are full of holes and 'nit-picky'. In the background of climate change, his talk is intelligent and timely.

[@darrenjeromemusic]

Great talk! For future innovations with regards to solar space travel, which might I add is going to be one of the best ways for humanity to extend its travels away from our solar system as our star passes through its red giant phase. Fossil fuels and even land based renewable energy technologies will be far to inefficient and impractical if we are to become a space fairing race. This is the best area of focus for humanity in the long run, Space X's mission to Mars will be key initially, also it will reduce the potential for extinction from various factors as two planets are better than one. I am sure it is possible for humanity to locate and settle on further planetary bodies in the next billion years!

[@susankrevitt2609]

This TED Talk by Joe Jordan on why we need to WAKE UP and connect with the use of SOLAR ENERGY makes me want to get....politically active or ... something! How obvious it is!!! Well, at least I can post it on fb, or something...

[@PaytonHatch]

Did he say his solution is to get involved politically to make the "dark" fuels more expensive so that the extreme cost of solar is not a hurdle? What type of solar power plant is he suggesting we use? Solar is not cheap and will not be cost effective enough in the foreseeable future. Thorium still seems like the better solution.

[@thefunnies2011]

+Payton Hatch , I didn't like the talk, either, but the statistics you can find here: cleantechnica.com/2015/02/25/solar-pv-will-cheapest-form-power-within-decade/ , here: www.iea.org/Textbase/npsum/ElecCost2015SUM.pdf and in many other places on the Internet show that PV (Photovoltaics , i.e. solar energy) is coming down in price rapidly - faster than any other form of energy (ca. 50% in the last 3 years). Today (late Q3, early Q4/2015), PV is already the cheapest source of energy for about 5-10% of the Earth's population. This number will go up to 30-40% within less than 5 years. Why would you say that "Solar is not cheap and will not be cost effective enough in the foreseeable future." ? If you take all direct and indirect subsidies out of the picture, solar PV looks even better by comparison. I don't mind LFTRs (liquid fluoride thorium reactors) - even though I live close to Fukushima (Japan, where a nuclear power plant was damaged by a Tsunami), because I believe we need a mix of energy sources. But I disagree with your statement. Side note: I presume that small islands and outback towns in Australia/US/Canada/Brazil/... will most likely have an easier time installing PV than a fission reactor.

[@markmuzenhardt9562]

+Payton Hatch Given that fossil and nuclear fuels are fully destroyed after use, solar is in deed one of the cheapest fuels that are known in history of mankind.

[@jeffbailey8333]

Solar is already cost-competitive without subsidies in many areas in the U.S. It may be time for you to get used to a new reality!

[@vincentrobinette1507]

@@jeffbailey8333 That's absolutely right. Solar is 1/5 the cost per installed watt than just 20 years ago. 1/10, the cost of 30 years ago. Now, we need cost effective efficient grid scale electrical energy storage. Batteries are a great idea, but very expensive, and there may not be enough materials to make enough batteries, for renewable energy to become 100% of our electricity. No one technology can get it done: We need them all. Nothing's off the table.

[@achalhp]

*Thorium Molten Salt Reactors* and Nuclear fusion need help from innovators like Joe Jordan. Solar Energy has limitations: *Dilute : need large area* * *Seasonal variations - Need fossil power backup* * *Intermittent on hourly basis - need battery/pumped hydro backup* * *Location specific*

[@alians1978]

If you think you can do it cheaper than Fossil Fuel, stop talking about it and start a company that produces clean energy & become a millionaire

[@metalhippiedude]

Why don't you start a coal mining business and become a gazillionaire?!?!?

[@chasmarischen4459]

It's already been done, and those that don't learn on their own will be left behind.

[@ok5731]

The USA has states bigger than Germany and I don’t think Germany’s solor energy is a raving success. Bottom line- there are currently no affordable solor set ups. The ones that work the best won’t last long enough to be worth it. Storing solor in water is the best you can do.

[@zodiacfml]

Luckily, we had the eclipse this year and solar PV now seems unstoppable.

[@robertfield4103]

Nutty. Has this guy ever build a power plant or produced any MW-hr of electricity?

[@markmuzenhardt9562]

+Robert Field Have you done so?

[@robertfield4103]

Yes, I have been doing just that for the past 40 years.

[@goomer91]

how does your power plant generate electricity?

[@markmuzenhardt9562]

More than you can imagine

[@goomer91]

Robert Field If you've been doing it for 40 years then my guess is that they generate electricity from fossil fuels. this guys is talking about the alternative that we need to get on board with before we complete fuck our whole ecosphere.

[@jessstuart7495]

The costs of fossil fuels will rise as they become more scarce making solar even more favorable. Hopefully the planet will not suffer devastating warming until that can happen.

[@McGr3gg3rs]

2019?

[@ResearcherTony2]

tried solar but need kw's not watts. 3 panels rated for 450 watts and I still cant even made a cup of hot coffee.

[@metalhippiedude]

Sorry your math is wrong. If you paid $622,500 for a 622.5 kW solar electric system, it would only need to be on at full power one hour a month to meet your bill. Many areas get an average of at least 4hrs of full sun per day. You'd only need to spend $5200 on a 5.2kW system to meet your needs (5.2kW * 4hrs/day * 30 days/mo = 624 kWh). However, installation rates are at least twice that, so you'd spend ~$10400 - $13000. That system would put out good power (slowly declining) for 30 years or more with a little maintenance.

[@gasdive]

You're doing something wrong. 450 W should boil a cup of water in 3 minutes. My system has produced 19 MWh, enough to make 800 000 cups of coffee.

[@bobbob396]

[@orvillebeers9651]

Didn't say anything helpful, like how to buy products to help us all. ALL TALK, No help .

[@robertfield4103]

Starting in ONE billion years the sun will red giant? No learned astrophysicist would agree with this time line. More like FIVE billion, not ONE billion. How can this guy have any credibility?

[@jeffholman2364]

More like 2 to 4, but whats a billion among friends?

[@gasdive]

It's about a billion years until the oceans boil, which was his main point.

[@robertfield4103]

Does he know that German consumers pay 3x the electric rates as found in the US? Is he willing to pull out his credit card to help you pay your (solar) electricity bill?

[@markmuzenhardt9562]

+Robert Field German consumers are paying 3x the electric rates as found in the US because of huge subventions for nuclear energy and fossil fuels till today.

[@RichardKingADI]

...and to help subsidise those who install solar PV panels!

[@pedropola882]

"Are we gonna make it as a species on this planet?" Well, not the way you are dressed buddy. Remember: heat is energy. The way you are dressed it should be 90° inside! If it's not-and it likely wasn't-he was losing heat (energy) thru his skin.

[@alexgalal5990]

i still dont get why hes dressed like that, even with his sandals on would still be ridiculous lol... atleast we got to see ghandi give a great lecture on solar power

[@alexgalal5990]

yea there is... hes giving a TED lecture

[@lebergerdesphotons4565]

joe is a coincidence theorist.

[@TheSnowPlowShow]

This man is a con artist.

[@HeyU308]

Agreed.
