Disputed inquiry clears bubble-fusion engineer

[摘要] An inquiry has exonerated nuclear engineer Rusi Taleyarkhan of misconduct with respect to allegations made internally at Purdue University in West Lafayette, Indiana, officials announced last week. Taleyarkhan claims to be able to produce fusion by collapsing bubbles in deuterated liquids. His work promised to improve prospects for developing a clean source of energy, but independent scientists have not been able to replicate the result.
