Better and cheaper batteries

I wrote a couple days ago that solar power is getting cheaper and cheaper every passing year. Well, this is good news but to fully realize my dream of a fully solar-powered society, we need to develop way better and much cheaper rechargeable batteries to store all this energy.

We all know about the great progress made by Tesla with its electric cars in terms of driving range. Launched recently, the Model S 100D offers a range of 335 miles on a full charge! Thanks to Tesla’s advances in battery and charging technology, these superb cars are reaching an ever larger market.

To continue with Tesla’s products, you certainly have read about its Powerwall. These are simply rechargeable batteries for the home that are based on the familiar lithium-ion battery technology. Li-ion batteries are now commonly used in consumer electronics. Tesla successfully drove the costs down by mass producing these batteries and thus benefiting from economies of scale.

Now, what about mass market consumer products? In the last few years, we have seen more affordable and reliable external batteries (power banks) or portable chargers for sale. The prices went down dramatically, and now you can find very handy products for people who are always worried about the battery status of their laptop or cell phone. I am such a person.

Right now on Amazon, some of the most popular portable chargers for your cell phone or other small electronic gears are from Anker again. You should definitely check the Anker PowerCore and Astro series and see the full range of high-speed chargers.

This best-selling Anker PowerCore portable charger sold for less than $30 is more than capable of charging your iPhone a few times.

This Anker Astro model sold less than $20 is also very popular given its ultra compact size.

For laptops and notebooks, you would obviously need a much larger capacity portable power bank, and the current favorite is this one from MAXOAK below.

Ever cheaper solar energy and products

If you followed the news recently on this topic you may have read titles like these:

Unsubsidized wind and solar now the cheapest source for new electric power

Solar Could Beat Coal to Become the Cheapest Power on Earth

I am a big believer in solar energy, and I am convinced that we will be able to rely on solar power for most, if not all, of our energy needs within a couple of decades. The reign of oil and gas will finally end. Obviously, we will need to develop better and affordable batteries to truly benefit from cheap solar energy.

I was checking, and I saw that solar-related products are quite popular now that the prices went down and quality went up these last few years as far as I can tell.

This is now summer time so if you are looking for a solar panel that can charge your smartphone or tablet while you are camping in the wild, I do recommend the solar chargers from Anker like this one below. These foldable solar panels very well designed for outdoor use.

I would also get one of these solar lanterns for camping from Suaoki for less than $20.
