Sure they have poor energy density, but they are very easy to scale to fairly huge capacities.Rorschachhttps://www.blogger.com/profile/11848860674369931761noreply@blogger.comtag:blogger.com,1999:blog-6002016549730514348.post-13725159516887606952010-11-22T23:17:29.582-08:002010-11-22T23:17:29.582-08:00Use of renewable energy has depicted in form of so...Use of renewable energy has depicted in form of solar devices like solar panels, solar water heaters, solar cookers, solar calculators etc. These small devices using which solar power be harnessed. Also set up solar electricity at home instead of electricity from government.

There is a world of applications going begging because the world isn't perfect. During the past 30 years, I've run TV's, radios, batt powered razors, lights, chain saws,welders,computers, mixers, ice makers, annnd battery chargers.<br />This solar system is stored on 6 volt, 12 volt, used, discarded, new, series, parallel, C,D,AA, and AAA storage devices where and when I found them. Any is better than none.blue7053https://www.blogger.com/profile/10803506330257283410noreply@blogger.comtag:blogger.com,1999:blog-6002016549730514348.post-91957299367530615892010-07-20T00:18:39.474-07:002010-07-20T00:18:39.474-07:00What is your opinion of bipolar batteries in gener...What is your opinion of bipolar batteries in general?

It's probably more viable locally. <br /><br />Actually, to talk about the 2 technologies, solar and batteries, can someone talk about the numbers side by side? It's hard for anyone not working in the field to imagine in terms of energy can generated/stored.<br /><br />Solar has on-off times (day-night), so question is how much energy can it generate on AM1.5 per hour per square meter for say, 8 hours? And how much battery materials are needed to store that same amount using current commercial oxide or phosphate batteries?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6002016549730514348.post-57018981998361692482010-07-15T04:38:12.548-07:002010-07-15T04:38:12.548-07:00Anonymous:

With most batteries costing more than $500/kWh, the feeling is that its hard to make much of an inroad. I think Na-S is the system to beat, not NiMH! <br /><br />One of the requirement of the ARPA-E proposal was >80% energy efficiency. Couloumbic efficiency is not the issue; its the energy that matters. <br /><br />VenkatVenkat Srinivasannoreply@blogger.comtag:blogger.com,1999:blog-6002016549730514348.post-43792505374522507152010-07-14T08:59:37.196-07:002010-07-14T08:59:37.196-07:00Fantastic, it'll be great getting your insight...Fantastic, it'll be great getting your insight on both markets.

Why not focus on NiMH (OK) and LiFePO4 which has >>95% round trip efficiency? Flow batteries are poorly suited to distributed applications and the challenges with central utility scale installations mean that they'll take forever to put in place. Plus, for Solar, it easily makes the most sense to perform generation to storage in the DC domain rather than moving energy across an AC grid and incurring 4 different conversion losses plust transmission loss...Anonymousnoreply@blogger.com
