SCIENTIFIC FREEDOM ANDRESPONSIBILITY

by John T. Edsall, for theCommlllittee on ScientificFreedomii and ResponsibilityRetail $3.45. AAAS menmnber(prepaid) $2.95.

Are lvoi concernied with the presentand future uses and misuses -ot sci-ence and teclhniology? If so, be sure toread this report. It studies and reportson the conditions required to give sci-entists and engineers the freedoml andresponsibility to speak out. It pre-scribes criteria and procedures for theobjective and imlpartial study of con-flicts concerning scientific freedomand responisible scientif-ic conduct.And it encouLrages the developmiientotf mieclhanismiis for resolving stuch dis-putes. This cogent and meaningfulreport deals frankly with the valuequestions facing the scientitic andteclhnical comm1llIunities and does notstraddle the hard ethical choices.

CULTURE AND POPULATIONCHANGE

A revised edition by Irene Tinker,Priscilla Reining, Warren Swidler,and Willianm Cousins. Preface byMargaret Mead.Retail $3.50. AAAS nmember(prepaid) $3.00.

This widely read position paperoriginally was prepared for the WorldPopulation Conference held in Bucha-rest in August 1974. It examines thecultural factors impinging on popula-tion matters and points to the needfor governments to integrate suchfactors into their official populationpolicies. The revised edition has beenexpanded to include a commentary onthe World Population Plan of Actionformulated at Bucharest. This is aninteresting and informative report foreveryone concerned with the complexinteractions of culture and populationpolicy.

COURSE ENROLLMENT PRESENT TEXT

4 FEBRUARY 1977 439

A practical electric car could go a longway toward reducing America's dependenceupon foreign oil. To satisfy a large fraction of

.S. urban driving needs, such a car shoulddouble or triple the range of present electricvehicles. Urban driving ranges of 30-50 kilo-meters are now offered by improved lead-acidbatteries with specific energies of about 35 watt-hours per kilogram.

T e Research Laboratories at GeneralMotors recentlyhas moved moreenergetic batter-

_ ____ ies a step closerto reality. OurElectrochemnistryDepartment suc-cessfully devel-oned and testeda compact lith-ium/iron sulfidecell that achieved

amaximum specific energy of 115 W. h/kg. Thiscell is only one-sixth the size and weight of alead-acid unit with the same capacity.

During a continuous test of more than 14months, the cell underwent more than 700 deepdischarge and recharge cycles. As far as weknow, that's some kind of world's record for ahigh-temperature battery. (It operates at 425-5000Celsius-about the same as a self-cleaning oven.)

Future high-temperature batteries could in-crease the range of battery-powered vehicles to300 km. Electric utilities could use such bat-teries for storing energy generated during low-demand hours to be used during peak periods.

The perfor-mance of other '800electrical energy 6systems we restudying is shown 200in the graph.oMuch closer tocommercial appli- U_.8cation are our wambient - temper- 40
