1680年,英国著名科学家牛顿设想了喷气式汽车的方案,利用喷管喷射蒸汽来推动汽车,但未能制成实物。
1769年,法国人N·J·居纽制造了用煤气燃烧产生蒸汽驱动的三轮汽车。但是这种车的时速仅4公里,而且每15分钟就要停车向锅炉加煤,非常麻烦。后来车在一次行进中撞到砖墙上,碰得支离破碎。
1885年是汽车发明取得决定性突破的一年。当时和戴姆勒在同一工厂的本茨,也在研究汽车。他在1885年几乎与戴姆勒同时制成了汽油发动机,装在汽车上,以每小时12公里的速度行驶,获得成功。
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
