DailyDirt: Better (Bigger) Batteries

from the urls-we-dig-up dept

Battery technology is getting better all the time, but unfortunately not quite at the same pace as Moore's law. While some folks lament the bottleneck of pocket-sized batteries that limit the operation of a phone or laptop to just a few hours (or a couple days on standby), some bigger batteries out there are limiting the growth of renewable energy use. Here are just a few battery projects that could solve some larger scale energy problems. If you'd like to read more awesome and interesting stuff, check out this unrelated (but not entirely random!) Techdirt post via StumbleUpon.

    Not really, electrical energy from a power station is not stored it's generated as required, with significant standby running costs.

    The benefit of batteries is they can stop off peak power and use it for peak, the first post if correct batteries do not produce power, they store it.

    Batteries are also DC, Direct Current, the grid is AC (alternating current) for the batter to be grid connected you require an inverter. Batteries are 'lossy' they take more energy to charge than they can deliver when discharging, plus the inverter has losses as well.

    Also being low voltage and high current you need very heavy cables to transfer power and you cannot transmit it long distances.
