  1. Why do you think if it would be possible to stop aging in all the cells in general, neurons are going to be the exception?
  2. So what is the problem if we would be able to stop neuronal aging at the cellular level? Even if it would be possible, it is very dangerous because if human personality could be digitalized and stored "at the server" it means it could be easily enslaved. But for now I don't see how it could be done with any technology I can imagine because brain functions are closely connected to a physical and chemical properties of the brain matter.
  3. In this case it is more important how neurons are connected to each other than the cells themselves. There seem exists copying mechanism in the brain which transfers the old connections to a new regions of a brain. Certain "brain plasticity". For example there are many cases when after destruction of some narrow brain region other regions took the functions of the destructed region and person almost completely recovered. I think there are not too many cases when after a stroke all the memories and personality would gone forever and completely.
  4. Are there any scientific experiments which prove it? For now I don't know proves memory and personality are stored at the cellular level. According to some studies new brain cells are created until death. Also it may not be necessary to replace cells but just stop aging at the cellular level.
  5. Don't you think that insufficient funds are allocated to combat aging and this technology is coming late for a common public? This is a problem which affects everyone. What funds could be allocated if every person in relatively developed countries would give $1000 USD to combat aging and how soon some sound results will appear?
  6. If it is assumed that men-made gases cause greenhouse effect and this is really terrible, then why humanity cannot create some potent gases to counterattack the problem? For example some potent agents which reflect well only UV rays and harmless to any leaving beings? Would not it help to cool Earth down and protect leaving beings from UV rays?
  7. Can someone explain how MHD can work on electrolyte solutions similar to a salt water? If there is no free electrons but only positive and negative ions than what runs through the external circuit to generate power?
  8. Changes in electric polarization could be achieved with help of electromagnetic induction and magnetic fields it seems, we don't necessarily need a plates or free charge accumulation. Magnetic fields are formed around wires when current passes through. Possibly it may resemble magnetic polarization of a permanent magnet when current passes through. I guess we may store energy in a permanent magnet as well by polarizing it first and then retrieving energy back in form of electric current when magnet looses its magnetic polarization for some reason. For example demagnetizes spontaneously. But permanent magnets are not capable to store a lot of energy. https://www.sciencedirect.com/science/article/abs/pii/S030488530500939X There is also such effect as dielectric adsorption in a dielectric capacitor. https://en.wikipedia.org/wiki/Dielectric_absorption
  9. Let say we have a ferroelectric capacitor which is capable to store 1 joule of energy. Then we remove charged plates and remain only fully polarized ferroelectric. Are there some ferroelectrics which are capable to retain its polarization for a long period of time? If yes, then are they capable to store energy just in polarization (without plates or free electrons)? Could there be some significant potential energy change when ferroelectric polarizes? If yes, how much? Will it release some energy (for example in the form of heat) when it depolarizes for some reason? If a capacitor with plates is capable to store 1 joule of energy then how much energy the same polarized ferroelectric would be able to store without plates? Is there some way to polarize a ferroelectric without free charge accumulation, but just by passing current next to it somehow?
  10. Also MHD could be used on the power plants or for generation in remote areas where is no wires. Portable generation. I have doubts they will bring them down much. All kind of Li-ion are quite expensive. Even contra, some manufacturers are planning switch to solid-state Li-ion or monolith-crystal cathode (like Elon Musk) in the future, what doesn't look cheap at all.
  11. Sorry if I'm wrong but the term "plug-in" is commonly reserved for hybrids only. In contrast to all-electric BEVs. I used it accordingly to tradition. Currently the longest electric range among plug-in hybrids on the wide market is 85 km. But I suggested in the future it may increase to 200 km. In this case plug-in hybrids may be able to run 95% of total time on electricity. And still will relieve the drivers from range anxiety and necessity to charge them fast.
  12. Still Chevy Volt does have the longest claimed range on this list among PHEVs. The rest (with longer electric range) are BEVs or fully electric. BEV stands for Battery Electric Vehicle. Typically they have no hybrid capability. I don't expect that majority of customers will choose all-electric in the nearest decades.
  13. Possibly plug-in technology is not exactly there yet. Chevy Volt is capable to run just 85 km on electricity at best. I'm looking at the plug-in's with 200 km electric-only range. Definitely they will need to release some much cheaper and energy dense batteries than Li-ion to make them affordable. Possibly zinc-air or sodium-sulfur?
  14. Cheaper in 10 years - unlikely. They will struggle to do it in 50. Plug-in's consume 5-10% of what regular non-hybrids do. I think it could be sufficient emission cut measure in the nearest 100 years even if they will run on fossil fuels. But there suppose to be enough ethanol or bio-methane to power them all.
