Već smo pominjali da je skladištenje 'n' transfer problem koji treba rešiti ako želimo da živimo u eokološkom raju koji nam je Star Trek obećao. E, sad:

Liquid battery could last for over 10 years

--- Quote ---It might be an ideal form of energy storage for solar and wind power.
     Modern batteries aren't hampered so much by their capacity as their long-term lifespan -- a lithium-ion pack can easily become useless after a few years of heavy use. That's bad enough for your phone, but it's worse for energy storage systems that may have to stick around for the long haul. If Harvard researchers have their way, you may not have to worry about replacing power backs quite so often. They've developed a flow battery (that is, a battery that stores energy in liquid solutions) which should last for over a decade. The trick was to modify the molecules in the electrolytes, ferrocene and viologen, so that they're stable, water-soluble and resistant to degradation. When they're dissolved in neutral water, the resulting solution only loses 1 percent of its capacity every 1,000 cycles. It could be several years before you even notice a slight dropoff in performance.
          The use of water is also great news for both the environment and your bank account. As it's not corrosive or toxic, you don't have to worry about wrecking your home if the battery leaks -- you might just need a mop. The safer materials are also less expensive than the polymers you usually need in flow batteries, and wouldn't require exotic pumps and tanks to withstand harsher chemicals. It needs less maintenance than other flow designs, too.
There's no concrete roadmap for bringing this battery tech to the real world. There's definitely a market for it, though. Renewable energy is becoming increasingly cost-effective, and inexpensive, long-lasting batteries would only help that. You could install solar power at home knowing that the cost of energy storage won't wipe out the money you save on your electricity bill.

Često se priča da bi torijumski nuklearni reaktori bili najbolje rešenje za ovu planetu: velika gustina energije, gorivo koje je pristupačnije od uranijuma, plus mnogo manje cimanja oko otpada i bezbednosnih rizika. Evo svežeg, veoma opširnog teksta na biznis insajderu koji obrazlaže ovu argumentaciju, daje istorijat itd.:

A forgotten war technology could safely power Earth for millions of years. Here's why we aren't using it

Ha, još ćemo mi videti parne automobile na torijumski pogon :)

Li-Ion Battery Inventor Creates Breakthrough Solid-State Battery, Holds 3X Charge

--- Quote ---
Short Bytes: A new glass electrolyte-based solid-state battery has been developed by the researchers at UT Austin. Led by the Li-ion battery inventor John Goodenough, the team demonstrated that their battery is better than Li-ion. It can hold an almost 3x charge, has more charging cycles, supports fast charging, and isn’t prone to catch fire.
 A new fast charging all solid-state battery has been created by a research team led by John Goodenough at the Cockrell School of Engineering. The American physicist John Goodenough got a Charles Stark Draper prize for the lithium-ion batteries which are now omnipresent in the digital world. It was decades ago, but even at 94, the physics pioneer isn’t going to stop developing things that impress and benefit the human kind.
The team has published a research paper in the Energy & Environmental Science journal. The noncombustible fast charging battery can hold a considerable amount of extra charge – almost three times – than the conventional batteries.
Goodenough says cheap batteries having more charging of cycles can improve the capabilities the battery driven cars and increase their adoption.
The design limitations of lithium batteries containing liquid electrolytes don’t allow them to charge quickly. If done forcefully, it would lead to the formation of metal whiskers (dendrites). Eventually, a short circuit would happen, or the battery would explode. However, that’s not the problem with the solid-state batteries.
The researchers have used a solid glass electrolyte in place of the liquid one. The glass electrolyte allows the researchers to use the alkali metal anode (negative side) which increases the charge density of the battery and prevents the formation of dendrites. Also, the glass electrolyte enables a battery to operate in extreme temperatures of -20-degree celsius.
Senior research fellow Maria Helena Braga has been working with Goodenough on this solid-state battery. She has been developing glass electrolyte since the last few years. It was until her collab with Goodenough, and another researcher, that she was able to come up with a new, now patented, version of the glass electrolyte.
Goodenough and Braga are working to improve their solid-state battery. Hopefully, some battery maker would step forward to adopt the new tech. Surely, solid-state batteries are the future, adding extra to miles to your Tesla ride or a day to your computer’s life.

U Americi je vjetar pretekao vodu po količini energije koja se ovim putem proizvede/ uskladišti. Naravno, dosta su tu pomogle velike poreske olakšice.

US wind capacity surpasses hydro, overall generation to follow
