2:10 one farm enough for 1million homes... There's approximately 8 billion people in the world. Let's pretend you want this to be the only source of power that provides energy for homes. Let's try and do some rough maths. Let's say 4 people per home that's 2 billion homes. The solar farm provides enough power for 1 million homes. So that would mean you'd need 2000 solar space farms. 2:20 The ground receiver needs to be 6km wide that would be 12000km. That's larger than the circumference of the moon. The amount of land you would need to use wouldn't be practical without taking up farmland or destroying natural habitats. I think overall when combined with other energy sources. It has potential to contribute to the global energy needs. It's a huge project to undertake

I wrote an editorial against militarization of space when I was a 16-year old reporter for the University of Michigan "Michigan Daily" paper about in 1967. I was a High School student at that time. I was also a member of the U.S. Air Force Civil Air Patrol Auxiliary which was leading to the ROTC, Reserve Officer Training Corp and a future Lieutenant commission. I had chosen a military career at that time. I wasn't criticize in any way for those editorial remarks. Unfortunately, a severe injury disqualified me from military service after High School. I've never let down my commitment to my country. My views on space are part of that. However, one day a few years ago, I wakened to listen to a news story where then Donald Trump signed an order for the creation of the U.S. Space Command. I've known of command officers' discussions against this idea before diplomatic attempts were made to prevent space militarization. I hadn't heard of any. My realistic views today reflect on my belief that space offers to provide a way to help the entire planet survive the coming challenges & to avoid possible conflicts. I've heard of such remarks by current & retired general officers. --JSW

For instance, the increase in the electromagnetic activity of the daytime atmosphere interferes with AM signals and decreased activity at night allows for a larger radius for AM transmission. (Am reflection happens at greater altitude) Would this increased activity during the day interfere with penetrating radio waves from space in a similar way as it interferes with AM transmission?

They haven't answer the basic questions of solar power conversion rates per square meter. The NASA guy didn't contradict Elon Musks claims that there is only double the intensity of the sun in space. We don't know how much of the solar electricity generated will make it to Microwave energy, what the efficiency rate of that is. I heard in a recent video that it is only 66%. Then how much of that beam is going to land on your antenna? Geosynchronous orbit is close to 24,000 miles if I recall correctly, and microwave beams are not a slender line like a laser beam is. That beam will disperse over that distance. Fourthly, how much of that energy that falls on the antenna will be converted to electricity and how much will pass through into the ground. Fifthly, if the power is only one quarter of the sunlight you could get as much power from solar panels with the same land area. We don't need much electricity after midnight, a simple battery could meet our nocturnal needs. This idea is insanely expensive and large. Sixthly, this could be weaponized , concentrated and be used to kill people, destroy airports and cities and maybe military bases. Or it could just miss the antenna and burn the grass a mile away.

this is an interesting concept but if you start to rely on this as your baseload then it seems like it leaves you vulnerable as all an adversary needs to do is destroy your satelite(s) and they take away your power. we need to be thinking in terms of energy security and independence... unless you can somehow defend your space assets againt all threats but with USA and China looking into this, it is going to lead to the militarisation of space. Looking at the Russia Ukraine conflict, Russia is able to target Ukraines power stations and even though they are unwilling to directly attack nuclear power stations (due to fear of political backlash) there would be no such problem with destroying a solar space satellie as it would not cause nuclear consequences. so perhaps its better to just focus on more and more efficient localised and decentralised solar + storage. by the time this space satellite concept can be deployed at any meaningful scale, terrestrial solar + storage will have already become cheaper and more efficient which will make the space solar unnessesary

Please explain why when asked about the powerloss issue, they didnt elaborate only explained that "Musk is wrong". Thats fine if he is wrong, but why not answer the question? Based on _current_ microwave technology, the losses are at least half of the captured energy in space. Conversion and atmosphere is a _real_ problem, especially in space, since conversion needs heat management which is not easy to do. The other "undiscussed" problem all the time, is the impact on the upper atmosphere it has (ionosphere is impacted by microwave radiation) and the problem of atmospheric dispersion means a large portion of the energy is _actually_ going into heating up the atmosphere? Thats insane by itself. Where are the "scientists" simply explaining how these key problems are going to be addressed?

Идея и планы построить космические солнечные электростанции и доставлять из Космоса энергию на Землю для обеспечения ими потребностей в масштабах континентов не представляются продуманными с общеметодологической ( ф и л о с о ф с к о й ) точки зрения. На протяжении 2-х миллиардов лет Природа при помощи фотосинтеза аккумулировала энергию Солнца, поступающую на Землю, и к о н с е р в и р о в а л а её в остатках растений, тем самым снижая окружающую температуру на Земле. Врезалось в память когда-то прочитанное, что если бы не поглощение растениями поступающей энергии Солнца, то на пустынной Земле установилась бы температура значительно выше 100 градусов. В обобщенном приближении можно считать, что в течение последних 200 лет разбросанные по континентам Земли тепловые электростанции (на угле, нефти, газе и другом топливе) обеспечивали энергетические потребности человечества, сжигая при этом законсервированные Природой энергетические ресурсы Солнца, поступавшие на Землю в течение 2-х миллиардов лет. Сжигание сопровождалось 1) выделением тепла; 2) вредными химическими выбросами. А потребляемая электроэнергия в конечном итоге практически преобразовывалась в тепло. Вот и получилось, что дополнительно к текущей солнечной, поступающей на Землю, энергия от работы электростанций способствовала медленному сдвигу теплового баланса (и, соответственно, температуры) на Земле. Расплата вылилась в ныне сплошной поток природных катаклизмов. В общем случае, заложенное в упомянутую идею д о п о л н и т е л ь н о е до существующего природного поступление энергии на Землю из Космоса , в конечном итоге (даже без вредных химических выбросов!) будет приводить к дальнейшему повышению установившейся температуры на Земле. А не к решению проблемы глобального потепления... Другое дело, если осваивать и массово использовать для земных потребностей аккумуляцию и консервацию солнечной энергии, природным путем поступающей с е й ч а с на Землю. [26.03.2024]

It's good if we have something for future but antagonism of capitalism cannot be solved and is most dangerous to existence as its conflict with majority as Engels rightly said "abolition of anti thesis between town and village is utopia just like abolition of anti thesis between capitalist and wage workers"

Just to make a VERY fundamental point here... The Sun is space based and it sends us solar energy 24/7 to 50% of the world at any one time. A solar farm 200miles square could supply the United States with an excess of solar generated electricity, thus that it could even export the stuff it would be so awash with power. When you look how small a plot of land that is by comparison to the land mass, and the profligacy of American power usage, sticking stuff in space to do what can be achieved far more cheaply and easily on planet Earth makes zero sense. This is just more fluff and nonsense generated by those who want to slow the transition to green electrical power by making it seem like rocket science. Continuing with America as an example, that benighted nation has only just got its first wind farm at sea under way... just one. So wind power still has a huge way to go along with ground based solar generation. There is now a burgeoning industry in supplying and fitting giant battery farms around the world, using very inexpensive and reliable (but heavy) battery technology, which can keep the power flowing during those occasions when none is being generated (like at night). All this is available right now. It is being made and used ,right now. It is cheaper than using coal and oil,, right now. It takes about two years to payback the investment, right now. This technology was being discussed when I was a boy, over 50 years ago. It's so out of date it's pathetic, hearing this drivel from a news source that ought to know better for pities sake!

200 square miles? You are at least 25 times off. Total USA energy consumption in 2020 was 93 quadrillion Btu (see US energy information administration). It equals 27 trillion kilowatt-hours per year. Or 75000 gigawatt-hours per day. Average daily insolation is about 6kWh/m^2/day. That is USA needs around 12 billion square meters or 4800 square miles of solar panels to match energy consumption on average. To supply demand in winter time you need to about triple energy capacity: 15000 square miles of solar. To store energy for the night you need at least 75000 gigawatt-hours of batteries or $7.5 trillion for batteries only, if prices will fall to $100 per kWh. The figures can be reduced by using wind, nuclear power and pumped energy storage, but it's a very large undertaking anyway. I wouldn't expect that we will be able to keep current standards of living and transition the entire economy into carbon-neutral at the same time. Oil and natural gas are versatile and energy-dense substances. Replacing them will require much doing economically and politically.

A problem with only ground-based solar power is we do not have enough batteries to store what we need over times were we do not have access to sun. And you can't just transport power from one side of the planet to the other. It is expensive as hell and you lose some energy overtime when you have to transport it over very long distances

How Much FARM LAND would have to be converted to Solar Farm or how much FOREST would have to be clear cut to create the 200 square miles of solar farm? did you think about that? Also did you think about how much of the earth would have to be strip mined for raw materials to build that? FYI that long term goal would be on orbit construction from materials mined from captured asteroids so you wouldn't need to strip mine Earth for the raw materials. Yeah that part is probably 40-50 years out. The main point of this is the surface area of the earth based collector is much smaller and could potentially even be integrated with some types of farm land compared with ground based solar.

This is a joke, for so much infastructure for so little power in the 100's KW that's nothing to power a thousand homes? Are you kidding, are you an engineer or a dreamer? Nuclear salt reactors and the new fusion coming soon is the answer. This is a lot of rockets and fuel and expense for such a small ROI.
