Caltech professor and inventor Ali Hajimiri has a reputation for defying conventional wisdom and turning science fiction into reality. His latest and boldest project to date is wireless power transfer, and it could change the way we power our lives.

Musk fanboys can't contain themselves. There is no clickbait you triggered morons. It simply says Musks doubts the idea; Elon Musk is not the final authority on any subject. He's one person with one opinion. There are a lot people who doubted technology we can't live without today.
May not be efficient for Earth, but could possibly be better suited for an orbiting solar array above the Moon, then transfer the power to a moon base for a mining operation.
The same principle may work for Mars, but the distance from the Sun there significantly diminishes solar energy collection potential.
This guy is literally genius. now there can be true wireless charging. just imagine it. your sitting in your living room whilst all your devices are simultaneously charging on the move. People like Elon just want to steal these idea for themselves and pretend like they are useless ideas until they use them for their own purposes.
The man behind tesla and spacex says that this makes no sense. Do sou now get it, how dreamy this idea is? Wireless power transfer is 100 years old and on small distances usefull. Like 10cm. On a distance of 100 m you loose most of the power. This is bullshit guys.
Clickbait or not.
Everything in this world is full of clickbait. 'have you ever struggled with..' .. 'tired of'... Why dislike something because of clickbait? .. its all around you. Not just on youtube. Marketing overall is a type of clickbait. Something that catches your attention.
Does that change anything that the video contains? No it doesnt. If it didnt include Elon saying exactly what is in the title, then i would see it as clickbait.
As for the inventor in the video. Keep going. No successful inventor has achieved what he has set out to do by paying attention to what others say. Not even Elon Musk.
This solar energy makes me think of Tesla.
Plus.. read the heading correctly. It is said as a fact. Which was proven by the Elon Musk insert, with information as to why he has doubts..
Followed by why the inventor bets it will work.
Its an article. Just like any other.
Whether it works or not I appreciate the man’s attitude. Unlike Silicon Valley schmucks like Musk and Elizabeth Holmes he doesn’t seem to feel the need to swing his thang around to prove how awesome he is.
I'm on Ali's side, me and my dad have been thinking about this for a while now. All technology sounds impractical and stupid at the beginning, why did we bother to build a wheel when you can pick up things and walk? why did we bother to generate electricity if fire was easier to access? The truth of this is, Ali's thinking is more Nikola Tesla's than the company bearing his name.
This Guy says he put ants in a jar and they started building a HOME... Fucking liar. Ants only build a home around their queen. Other wise they scurry off LOOKING for the queen. I hate liars. And phase Arrays are useless when they cant be produced in a sensible and cost efficient way. BLOOMBERG is notorious for making videos about nothing and trying to pretend like it is something.
The title is misleading. Elon doesn't doubt it can be done, he simply stated that it wasn't economic. I do not doubt that there will be more applications for this technology, just not what he intends for it.
Elon Musk doubts anything which requires knowledge of physics. We don't want to hear any more from Elon Musk about how 'stupid' his competitors are while they're all defeating him, and advancing industries with their achievements. Obviously, he's the one who is stupid.
I don't see why one would go to the trouble of converting the solar energy into microwaves in space then beaming to the surface of the earth. What exactly do you gain by doing that?
I see the advantage of having 24x7 production of electricity but why not just focus the sun directly to a collector on earth, avoiding the losses in conversion to microwave and back? You just need a large optical reflector in space rather than solar panels and you achieve the same results, only much more efficiently. That is you get much more electricity produced for a given cost or for a given mass launched into orbit.
If we can shrink a phone to the size it is today...I don't see a reason why we cannot integrate this concept into the current grid as a source of power...the receptors need to be more efficient in dispersing the wireless energy into the grid...ideally if we could somehow amplify this energy...before passing it on...it really could work....and it would be consistent in terms of the flow...however weak it may seem now...it really is a great idea.
if you think this is impressive technology, then let me tell you something, last month a saudi arabian scientist has patent issued and made successful prototype of cell phone charger, that can fully charge a phone battery by radio wave that you found everywhere. Bloomberg if you want more information hit me up.
Elon Musk doesn't doubt the idea, he doubts that it will be efficient. Ali is just self absorbed and invents for the recognition, not practical success, and Bloomberg survives another day by using more misleading clickbait. WHEN YOU ARE A NEWS ORGANIZATION, AND YOU USE CLICKBAIT, YOU ARE A LIAR.
So, somehow, it makes more sense to buy a 100$ 2kg solar panel, put it into space for for ~6.000$, install it around a long range transmitting system (??$) that will have some efficiency losses, with the work of 10+ engineers and scientists, then to just buy 3 panels for 300$ and and have them installed by a single electrician on a spot of the 99.99% surface of the Earth that does not already have solar panels on it.
Same amount of power produced, one cost 300$ + 1 electrician hour, other costs 6.100$ + ??$ + 20+ engineer / scientist hours.
Oh by the way: The ~6.000$ launch cost for 2 kg ( Falcon 9 reusable configuration) goes up to ~10.000$ if you disclude ventures of Elon, and go with the second cheapest option currently available. Just saying on your comment "If there is anyone out there who could steer the thrust of technology from its own demise, and toward the betterment of humanity" - there a lot of people actively doing that, and this guy might be amongst them, but he needs to not just imagine and make "cool tech stuff", but also make it in a way that it practically and economically makes sense to be anywhere near of the frontier.
Let's assume crazy 90% conversion on send and receive laser. Now tell me how much will be lost in the 60km of air moisture and clouds? And then tell me the plan how to convince goverments to allow such powerful laser in orbit.. That can "miss" the receiver too..
Elon owns both a solar power company and a rocket company, both making the most cheapest _and_ advanced products within their industries. You'd think he would be the first to jump on this idea if it were actually feasible... Duh...
who cares if energy gathering is more efficient in space when you need 9 pounds of Rocket fuel for every pound you send up... just use the money you save by not going to space to build a bigger array on earth. Otherwise you really need to send something that can produce these into space and produce them there before the proper scale can be achieved.
You know what's funny is that if you don't see the benefit of this idea then what. Think about it Einstein said it E = MC2 which allows light to be captured at any given speed. Nikola Tesla already had a system in place for energy transmission using the earth as the conductor. It doesn't matter how fast you go in space or not light will always catch up and energy will always be there. Put a solar panel on or in your car to charge your phone you'll still get energy. And by the way elon may own a rocket that is powered by fuel and owns a car company powered by batteries why waste your time with fuel. You can create a turbine powered rocket or a mag rail gun rocket that spins.
I think if they used the energy in space, that may make more sense, instead of costly beaming and transferring to facilities on Earth. For instance, the space station, junk clean up, surface mining on the moon, and much more!
