Promises lo bring wind power back Scientists develop new type of windmill Bv JEFF CAJMIUTIIKIIS Herald Ottawa liim'mi OTTAWA Scientists with the National Research Council here have developed a new type of windmill. It bears no resemblance to the familiar ones found in Hol- land, or even to the smaller ones still used lo pump on farms around Uio world. If anything, it looks at n dis- tance like a nearly-round hoop skewered by its support pole. But it promises lo bring wind- power hack into prominence in many areas of the world, in- cluding parts of Canada.

Will the development of relia- ble and economical power stor- age systems, the wind generator could eventually find its way into widespread use by civilians in all but the calmest areas of Uie world. One scientist even joked about the possibility of mounting a 20- fiwler on one's cottage, to save money on the electric bill dur- ing those blustery days which inevitably arrive on weekends and during vacation. One 30-foot wind generator could probably produce enough peak power for cooking, lighting and heating in one house in the Arctic. But unless the winds were nearly constant-! y above 10 miles per lower limit for the wind generator to pro- duce system for storing power would be re- quired. DRB scientists are proposing various sytems, from Ihe stand- ard lead battery lo esoteric fuel cells. The nickel cadmium battery would be more useful in the colder areas, since it mil work well down to minus 40 degrees, whereas the lead storage batter- ies encounters trouble at zero degres. The windmill ivould be de- signed to produce more power than needed ind the excess power would be slorccl for use during calm periods. Computer simulations liavc shown that a life-sized NltD wind generator could provide uninterrupted power lor a small station in this manner in the Alert area. The computer was given wind speed data from past years. In addition to being simple to build and operate, the wind gcii- e r a t o r is major advantage over conven- tional windmills. The "hoop" of the generator is really two curved blades at- tached to a metal rod at the top and bottom. The metal rod nor- mally rotates with the blades, and is mounted on bearings. In profile, each blade is shaped like an airfoil. This allows wind hitting It from any direction to turn the wind mill. This in turn elimi- nates the need for expensive and complicated devices lo keep Ihe windmill "propellers" point- ing into the wind. The NHC wind generator is just as efficient as its bigger will extract about 45 per cent of the energy from the wind. In theory at least, there's no reason why the cheaper NBC device should not eventually re- place the hundreds of thousands of existing windmills in use around the world for pumping wafer. The NRC scientists-Peter South and Raj Ilangi of the na- tional aeronautical establish- been working ou the idea for about two years. Originally, according to Dr. Rangi, they were thinking in terms of developing a cheap power source lor developing countries. liecent altempts at windmill development for such uses have always been too costly. But then DRB came along wanting to use it for the raili- Inry in Canada. Then the scien- tists realized it could be useful in other areas, particularly along the Pacific and Atlantic coasls. The idea behind the strange- looking windmill is not new. It was patented in France about 40 years ago, hut never exploited. Two things may result in its being exploited today: the grow ing demand for alternate sources of pairer even in indus- trialized countries and the in- creasing concern about the envi- ronment, NRC's wind generator, com- bined with DRB's power storage expertise seem lo make the Ca- nadian approach to "catching the wind" Ihe most practical available today. Resentment mounts in Pacific against French nuclear tests By J. C. GRAHAM CP Correspondent AUCKLAND, N.Z. (CP) Resentment is mounting in the South Pacific against French nuclear tests in the area. There are signs that protests may be followed by stronger action. News of plans for action by a Canadian Green- peace rein" forced the determination of South Pacific groups already active against the tests. The prospect has been opened of a wider Pacific Basin front than hitherto expected. The series of French atomic tests has drawn little attention in much of the world, perhaps because of the remoteness of the site. Until well into the 1960s, French tests were carried out in North Africa, but growing anger there brought a change of venue. While few people realize it, France still controls a sizable empire in the Pacific, includ- ing nickel-rich New Caledo- nia, the far-flung islands and atolls of French Polynesia centred on Tahiti, and the jointly-ruled condominium of Ihe New Hebrides, shared with Britain. MADE DOZEN PROTESTS Since 1966, France has been carrying out a series of at- mospheric tests of nuclear de- vices from Mururoa Atoll, in one of the numerous groups which make up French Poly- nesia. Mururoa lies some 640 miles to the southeast of Ta- hiti. New Zealand has made about a dozen protests against .he French tests. In fad, it has been one of the most con- sistent protesters against all nuclear tests, having pro- tested against American, Rus- sian, Chinese and French Icsls. But (hose at Mururoa, in the South Pacific, are of closest concern as they are learest. New Zealand has set up monitoring stations in various island groups lo check for harmful effects Dangerous levels of contamination have not so far been recorded, but he possibility of an accident remains si) long as the Le.sts continue. Announcing a further pro- test against a test series to be carried out by France at Mu- ruroa in 1972. Prime Minister J. R. Marshall also said IhaC further action was being con- sidered. He did not specify the kind of action the government had in mind. His warning was reinforced by a further statement by Sir Kcilh Ilolyoake, foreign min- ister and former prime minis- ter, who said New Zealand felt it was lime the French govern m cut heeded the wishes of inhabitants of the. Pacific area over nuclear test- ing. Sir Keith said the lest scries scheduled by France and the two atmospheric tcsls already conducted this year by the Peoples' Republic of China were In direct conflict with the principles of the partial test ban trcnly of 1M.1. There some comfort, Sir Keith said, In the (not that this ycnr'.s test series would apparently be reduced In scalo from Ihose held In pre- vious years, but New Zealand wanted all nuclear testing in the Pacific to end. New Zealand organizations of many kinds have supported the government and called for stronger action. Sir Dove- Myer Robinson, mayor of Auckland, has ruled that as a protest he will not receive any French visitors in his official capacity while the tests con- tinue. New Zealand's opposition to Ihe tests has been paralleled by mounting government objection hi Australia. In addition lo official pro- lesls, trade union organiza- tions in the two countries have discussed the possibility of boycotts of French shins and aircraft bound for Tahiti. Limited action has already been taken at limes against handling material likely to be required for test purposes. Suggestions have been made for strong joint action at the United Nations confer- ence on the environment to be held at Slockholm in June.
