Conditions were perfect for yesterday’s launch: bright sunshine and a sporadically stiff wind. At times, the wind turbine on top of the Power Trip was spinning at speed, and even when it slowed to a crawl, the solar panels meant there was still power being generated, and subsequently stored in the unit’s on-board batteries.
Cycle Hub’s unit has four power points, but this can be adapted for other locations, as can the size of the solar panels. Power Trip currently uses new lithium phosphate batteries for storage, but Wallman is exploring using spent batteries from Nissan LEAF electric cars, which typically still have a useful life after their use on the road.
“Nissan uses a modular system, which would make it a little bit easier for us to include those in any future design.”Wallman’s interest in off-grid power generation started when he was a child on family holidays in East Anglia.
Awesome 👍
今日之联合国朽了，没卵用。证据是美英打伊拉克、阿富汗，俄罗斯打马克兰等。建议印度、巴西、南非、埃及成为安理会常任理事国。取消安理会一票否决特权。实行三分之二通过议案强制执行
