Exactly. The problem with solar energy is that it's limited. We know that it's not possible to get more than about 1004 watts per square meter from solar energy (and that is the amount received when the sun is directly overhead). A practical solar passenger plane is basically impossible. Now, I could see a solar zeppelin being a possibility for passenger travel. I do agree that in the future, we will probably have solar panel roofs. I anticipate my next roof (which I'll need in about 15 yrs) will probably consist of solar panels. I see that as a supplement, though, not a total solution.
There are 7+ billion people on planet Earth and they're not going anywhere. Sure maybe you can shuttle a handful of Earthlings away from Earth but why...preservation of the species? We're just a bunch of somewhat meaningless biological units which are vulnerable to the powers and will of the Universe. Kind of like those living in Sicily around Mt. Etna, or those living around Yellowstone, in which all of them are at the mercy of Mother Nature. IMO intelligent humans are not unique and not important or contributing to the system of the Universe...therefore we're as expendable as ants. Money is always an issue! When we have people living in poverty, no healthcare, crumbling infrastructure, people and governments deep in debt, an iffy at best economy, money is an issue! Why pretend money is no object? Money controls every decision we make. I'm a proponent of space exploration and I wish we could do more, but wishing does not generate the money and interest necessary to encourage these programs. This IS NOT "lack of critical thinking and foresight"...this is reality...
In bold above is the summation of solar electric on any larger scale energy needs. And this is fine because if solar can produce 20% of all electric power demand then great! A solar zeppelin will work but it will be slow and only functions because of the lighter-than-air gas which is used...again solar would be supplemental. I thought solar panel shingles were already on the market? I have no problem with zoning laws to require all new construction, where applicable, to be solar assisted and this would have almost no impact on the financing of homes and business...
The amount of energy needed to transport crew, passengers, and cargo is non negotiable. The surface area of a plane will never ... ever ... receiver enough power from the sun for solar powered flight to ever be a reality. These planes work by having a minimally light load so the miniscule amount of solar energy that hits the surface of the plane is enough to generate the thrust needed to fly.
Earth's gravity is the pesky ingredient; create anti-gravity and perhaps we can have solar powered aircraft...and don't fly at night...
Yes but if we could manipulate gravity that means we can bend space and if you could bend space why would you need to fly?
False. Global temps have risen since 1998. Where do you get your information? Fox News? Then why is the rate of ocean warming fastest at the surface, and slowest at the depths?
Silicon manufacturing requires some pretty high temperatures that are not going to be achieved using solar energy
NASA says they ain't. history says they ain't. the only ones that says it is are people that want to tax energy to pay for more Obamaphones and those loooking for grants. heat rises. if it was being heated from the top, there would be little to no rise at the bottom. a candle under a pot will heat water a faster than a torch over it.
I take it from this that you don't have a single shred of evidence that there actually is an increase in volcanic hotspots. In which case, you lose.
False again. And still no citation to actual evidence, just the usual climate denier rumor crap. Oh, like denier favorite Dr. Roy Spencer, whose UAH satellite measurements show the temperature is going up? Fail again. And still no citations to real evidence. Precisely. Which is precisely what we have observed. Fail again.
The energy or power that will rule is the one that was put in people's minds by politics and mass media. Wind and solar are in while e.g tidal and geothermical are not (even not know or supressed at the wildlife and ecology foundations) Because the system (oil companies, politics, elites, banks, etc) does not want change to a better world, they promote wind and solar because has the least impact on oil.
Who knows a single business in any industry which is going to 'promote' something that potentially and negatively effects the bottom line? Oil companies are not owned by evil Doctor Goldfinger types...they are owned by millions of shareholders and every single one of the shareholders demands the highest and most sustainable profits. If someone wants to compete with the oil companies and others, then pony up the innovation and money and sell it to consumers...
