By then, inventors had already been patenting such devices for several decades, and other companies were selling a variety of electric erasure products. But what was so problematic about the humble eraser that it needed electrifying? In the days before computer-aided drawing and the ease of the undo command, erasing could be a delicate operation. To make corrections to a hand-drawn map, for example, two engineering professors in 1930 suggested first picking off the ink with a sharp knife, placing a hard surface beneath the map, and then rubbing it with a pencil eraser. The Presto Model 80 electrical eraser [above] was marketed to draftsmen, librarians, and artists. Held in the hand like a pen or pencil, the eraser vibrated to abrade a small area in need of correction. Today, some artists still use electric erasers for fine details in their drawings.","PeriodicalId":13249,"journal":{"name":"IEEE Spectrum","volume":"62 4","pages":"48-48"},"PeriodicalIF":2.6,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10960522","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143808914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies, after all, show that in developed markets, as much as 90 percent of all charging takes place in the home. It turns out, however, that the remaining percentage of charging is critically important. Drivers of delivery trucks and taxis, residents of apartment buildings, students on their way to college, families on vacation, and countless others have learned that driving an EV can be a struggle where public charging is scarce or unreliable. A 2022 survey by Forbes, for example, indicated that 62 percent of EV owners were so anxious about EV range that they had at times curtailed their travel plans.","PeriodicalId":13249,"journal":{"name":"IEEE Spectrum","volume":"62 4","pages":"32-47"},"PeriodicalIF":2.6,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143808908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
