All but eight of those 32 jurisdictions used the Power last year. The average Cost for installing and monitoring a wiretap was $35,508, according to the court office. The Cost fell $985 from last year but has More than doubled since 1980. The most expensive investigation was a racketeering probe by the .

Department spokesman Charles red Man also said the . Embassy in Man Agua Nicaragua had received Confirma Tion from the government there that the Volunteer Benjamin under 27, had been killed in Nicaragua. Under an Engineer from Portland ore., Wai the first american Volunteer killed since the contras began their guerrilla Campaign against the leftist Sandi nista government five years ago. Redman said the Brief government note delivered to the . Embassy wednesday night was dated april 29 and said simply that Between 7 and 8 , the North american citizen Benjamin under was violently murdered the United Stales has not received any other information and continues to press the sandinista government for the circumstances of Linden s death red Man said. He said there were conflicting report about Linden s killing and the United states has been unable to determine the truth. Redman also said the United Stal shas been in touch with the .-Baekcd Contra rebels but it May take some Lime before resistance leaders can get a detailed report from forces operating in the  he noted thai in a preliminary report issued in Miami the contras said under was killed when repel forces clashed Withan armed paramilitary group in Nicara Gua. The United states had sought to Senda team to the area of the clash which Redman described As hotly  but the . Embassy determined thai without assistance from the Nicaragua government in would be Loo dangerous Tor embassy personnel to travel to it area Redman said. The spokesman urged americans five Irig in the Central american nation to Register with the . Embassy there an to learn which parts of Nicaragua were Loo dangerous to visit. Approximately 1,500 americans live in Nicaragua. Redman said the United Stales Hope neither the nicaraguan government nor the Contra forces were targeting or kill ing american or other civilians. This was in apparent reference to one report from the area which said under and six other people were ambushed an attacked with grenades. Several members of Linden s family were to arrive thursday in Managua the capital. The .-backed Contra rebels said the 27-year-old Engineer working on an electrification project was killed during firelight Between contras and Sandi Nisla militiamen. The statement issued in neighbouring Honduras said govern ment forces were accompanying Linden and his nicaraguan co workers when the clash occurred about 80 Miles North of Managua. But foreign minister Miguel d Escoto in a protest note to Secretary of stale George Shutlz said Linder was Kidnap Ped and later murdered.

Tests of new solar cell promising scientists say new York a an experimental Type of solar Power cell has reached record efficiency Levels and one version continued to provide Power at night scientists reported Fri Day. The new results with photo Leckro chemical cells appear in the British journal nature. The experimental cells use solids and a liquid solution to generate Power while today s commercial Pho to Voltaic cells use Only solids. Al though the cells Are currently less efficient than photovoltaic cells proponents say i cells May compete commercially in the future. Photo electrochemical cells generate Power when Light strikes a solid called a semiconductor a which touches the liquid. The semiconductor then draws electrons out of the solution and the Electron flow which is electrical current runs through a circuit to dots work before returning to the Bulu lion. Stanford University scientists described  cell that converted 15 percent of the solar Energy fall ing on the semiconductor into useful cd cyclical Power. The highest efficiency previously re ported for such a Cal was 14 percent said Nathan Lewis of the Stanford team. In comparison state of the Art photovoltaic celts reach 21 percent he said. While the increase in efficiency appears Small the work is important be cause it shows a direction for further re search said Mark Wrighton a chemistry professor at the Massachusetts Institute of technology. The other nature paper describes a cell that stares part of the Energy in produces i Hurt draws on the stored Power to maintain its electrical output once Sun Light  from the Weizmann Institute of science in Reh Vot Israel reported the cell delivered a steady current Over two Days and nights. The cell per formed at i i.3 percent Overall efficiency considering the electrical output delivered immediately from sunlight and that regenerated from storage they reported. Stuart Lichtl a member of the Weizmann team now Ai Mit said the newly reported Ceil was the first to function about As efficiently As other photo acc
