Flow batteries: For when the wind don’t blow and the sun don’t shine

The Harvard prototype organic flow battery….Credit: SEAS A team of scientists and engineers at Harvard tackled the problem of storing electricity from short term or irregular energy sources, such as wind mills or solar panels by looking to improve on a type of battery technology known as a flow battery. As published in the journal […]

NEWS: Short List

Cell Biology – Biological clocks: Circadian rhythms not dependent on DNA | It has long been assumed that the internal clocks in all living things (loosely called the Circadian rhythm) is associated with DNA. Apparently, they are not. A new study by the universities of Cambridge and Edinburgh (UK) has shown that red blood cells […]

Another graphene application – supercapacitors

While everybody knows about batteries, supercapacitors seem like a well kept secret. The reason is fairly simple. While capacitors have been used for a long time in electronics, capacitors and their souped-up cousins, supercapacitors, have only recently become candidates for competing with the common rechargeable battery. Supercapacitors store electricity as batteries do, but there are […]

Advancement: Ultracapacitors as batteries

Call it ‘better batteries’ or simply fulfilling the need to store electrical energy for use ‘off line,’ the technology to improve energy storage goes on apace – step by step. In this case, the step is to solve a problem with ultracapacitors. These are the supercharged versions of capacitors – the long used technology for […]

Tech idea: Gravel silos to store wind or solar energy

Obviously there are times when the sun don’t shine and the wind don’t blow. Such times are called ‘interruptions of service’ for solar and wind energy generation. It limits their effectiveness as alternative energy sources. The solution is to store energy when the wind blows and the sun shines and release it during the non-productive […]

Algae-paper battery

Yes, paper can be made from algae (“pond scum”); and now it is possible to store electrical charges in such paper – that is, make a battery of it. Here’s some of the report in the Economist: Albert Mihranyan of Uppsala University in Sweden and his colleagues have built a battery that is, in essence, […]
