Looks so good!

I'm not a fan of Elon Musk, I never have been a fan of electric cars, his are not cheap. Elon is big on playing the media, and short on sucess in solar, electric cars, and space launches. I do not think the solar business is all that sucessful and IMHO no very cost effective to install on your house. There are many drawbacks to it. As far as the electric cars, same thing, there are many drawbacks, and I think both the selling points might be tax deductions, as a selling point.
As a retiree from the space program, I see a lot of problems with his falcon rockets, and their long term feasability as a reusable rocket. They stuck the landing last time, but at what cost? Like of not, he is not 100% funded by himself, he is getting government assistance, breaks, and incentives. It is not 100% private, even it it appears to be. Bottom line, the ability to land, requires additional weight, so that limits the payload ability. Far from being proven is how many times a rocket chassic can be reused, they claim zero damage was done, however that is totally untrue. Every launch will cause defects, and every defect is prone to further weaknesses, such as cracks, bracket stresses, etc. Also totally unproven is how many times their engines can be refired, and what has to be done to them between launches. Long term lifespan of new 3-D printing parts is far from proven yet. I worked 30 years on the Space Shuttle main engines, and their problems of these alloys, and reusablitly, allowable defects in materials is very complex. The data bas of knowing how certain defect occur, and propagate with age take a very long learning curve, and Space X is in the very early infancy of that curve.
They are a long ways from the level of major programs like the Shuttle, Mars missions, or even moon programs. At best the are a young and still evolving single rocket concept. They are off to a good start, but we should not think they are our only space venture company. NASA is still the boss.

I'm no expert on the space applications you mentioned BUT I'm an expert in electronics and still studying up quantum physics/mechanics professionally. We're discovering a whole new world with respect to "magic with magnetism". Wireless transfers of energy using a high frequency magnetic resonate coils is key for our future. Companies are starting up all over the world with this technology such as WiTricity for instance; seen here and more so explained here: .
When Giller talks about putting in resonate coils in the lanes to keep an electric charge to the vehicle (essentially recharge the vehicle in real time)... is asinine as the cost of that infrastructure is ludicrous! All you need to do is have GETcorp Towers transmitting their wireless energy to the cars within range albeit the cars will need a resonate coil built in them to receive the power transfer. Simple, simple, simple.... Fractions of the cost and no need for batteries either in the car. If you need more details, I can share.

Roger, I'm not very well versed in the electonic end, but liked that video about it. What it reminded me of was in metalury, they have induction furnaces using that principle,used usually in exotic alloys. They do require a lot of current to produce heat energy using an induction coil. The video example shows tapping off other units from the magnetic field, adding them one at a time, question is does the total output of power mulitipy, or is it reduced by the number of units tapping off the grid? As I said my electonics expertise is pretty basic.
I agree the things with magnetism are easy to find by just going to an amusement park, how many rides use that technology to accelerate rides. Thats another field my knowledge doesn't go far beyond basic motors.
Concepts and making things work is only half the battle. My main objection to some of these things like solar panals on homes, hot water heaters, electric cars, is they are not "cost effective" yet. That is why the government is willing to give you tax incentives just to buy them, because they know they have not reached being cost effective. I worked on and built the steam boilers, for the first Solar 1 power plant in Dagget, California. That is near Barstow in the Mohave Desert, on the road to Las Vegas, if you are not familar. It worked great, but had its drawbacks as the first one built. Wind and solar are great, but there is some bad effects on wildlife, and wind takes a very big footprint of land. Some say they are beautiful others say they are eyesores. It will take time and the cost effective part will come down. I'm sure this induction principle has its own hazzards of EMF, may prove not too healthy.
The electric cars have drawbacks, aside from people just liking a car with a motor, they are expensive. Nobody ever talks about the fact range is limited, you may not find recharing places that take time. You probably need to have a electician put in a special circuit and plug in at your home, plus we are all now being forced into water and power conseration, or you get fined. If you go over in KWH, your billed higher rates as you use more.
The solar panal idea was also sold on the Power department required to buy back your extra power back into the grid, but they are now getting out of doing that, changing the rules after the fact. Nobody really talks about the problems with solar, forinstance our neighbor installed them on a roof that was about 60% through its lifespan of 20 years. When he had to do a new roof, it cost him thousands of dollars to have the panals removed, and reinstalled after a roof repair. I would never put up panals unless they were put onto a fresh brand new roof. Many factors make it not such a good idea. I was going to replace my gas water heater with solar until I found out it cost about 3 times more.
Technology is great, but it has to be cost effective. Good subject!

Well, a few things to note (see some of my other posts to understand more on this subject).
1. Combustion engines are awful with respect to loss in the overall system which makes the electric car unique to this. So many moving parts, oils etc... Not needed any longer. Electric cars can hold charges to over 700 km's now if not more. Yes I get they are expensive BUT they are coming down in price as well "free" to recharge at Tesla recharging stations (a lot of them btw). Continuing to grow..
2. While the electric does require batteries for now... GETcorp's wireless tower can provide Ecars that are i nrange of the tower to maintain charge wirelessly. Different Towers can be made to power vertains manufacturers' cars and at tremendous distances with little loss .05%. It's new technology, but it's real and it will happen.
3. 200 countries agreed to stop using fossil fuels and oil by 2050 (may be way so much hate in the Middle East). This was announced a few weeks ago. Rockefeller annonuced as well their pulling all assets and ... (what's the banking term...) stocks from the oil industry. They announced that last Oct. Hence the fall of the markets and why the Nation Bank of Scotland told everyone to sell off everything they have within these assets/stocks. This pushed the electric into mass manufacturing once and for all.
4. If we had an abundant amount of element 115 (discussed by Lazar in his videos). We could have an alternative power source(s). There is real no need for combustion engines as Lockheed Martin/Skunk Works has addressed to the public. Their new crafts are wild to say the least.

Also, with respect to the losses in WiTricity... It's about a 5% loss overall from source at their frequency which I think it's around 1.6M hertz... I could be wrong. If the wall plug is 15 amps... anything will work in range that doesn't go over this. Repeaters can force the output range very well with a slight step down in losses - not much however.
Also, the end of the AC world is near too. DC is infinitely better than AC, only a few things will remain AC. This will help to reduce costs etc... I could go on here.
