Description:
Google TechTalks March 29, 2006 Vinod Khosla Vinod Khosla is a venture capitalist considered one of the most successful and influential personalities in Silicon Valley. He was one of the co-founders of Sun Microsystems and became a general partner of the venture capital firm Kleiner, Perkins, Caufield & Byers in 1986. In 2004 he formed Khosla Ventures. ABSTRACT On Wednesday, March 29th, by invitation from our co-founders and CEO, our special guest, Vinod Khosla, visited Google to deliver a tech talk about the emergence of ethanol as a viable, market ready, and competitive source of renewable energy. His presentation has been making huge waves in the investor, policy, and business communities and we are privileged to have had him take time to talk to us about the tremendous potential for ethanol's explosion into the market. Here are some recent articles that might be of interest in relation to this talk: Vinod Khosla, a Silicon Valley billionaire, who wants to save the world from oil http://www.economist.com/people/displaystory.cfm?story_id=5655161

現代淘金潮:玉米汽油

美國為了擔心糧食生產過剩,以每英畝48美元的代價,鼓勵休耕。但目前因為能源價格高漲,使用玉米釀製乙醇,使得玉米的生產量提高。目前美國有家ADM公司專門利用玉米釀製酒精,然後以85:15 h的比例與汽油混合,成為所謂的E85混合燃料(英文為methyl tertiary butyl ether, 簡稱 MTBE)。這家公司已經生產30年,承最近油價上漲之際,似乎利潤頗豐。在原油接近70美元一桶時,其利潤每英斗玉米可達五美元,而玉米之市場價格才僅二美元。

不過農業專家與能源專家仍然懷疑,就整個能源之應用而言是否真的合算。目前這些釀製乙醇的公司不但受到美國政府補助,而且在營業稅上也有51%的優惠。現在玉米市場價格平穩,倘若超過三美元,整個飼料市場就會開始吃緊,到時可能與E85的生產形成拉鋸局面,牛肉及奶製品的價格將會大漲。目前玉米價格維持如此低檔也有人為的因素,因為美國政府對玉米生產有大量的補貼,造成玉米生產過剩,也因而使玉米的價格低迷不振,並讓人產生這種暴殄天物想法。

實際上就能源學家的觀點:種植玉米也需要使用相當多的能源,由整地、播種、管理、肥料、收穫等過種均要動力與能源,辛辛苦苦產生的糧食又轉回為能源,整個過程反而不太經濟。只是因為人為創造的經濟因素,使某些環節成為有利可圖。比較實際的方式是利用玉米桿、麥桿、稻草等農業廢棄物為原料進行轉換,其意義較為重大。不過由於利之所趨,目前已形成另一種變態經濟,有些美國農民甚至組織合作社,積極加入這種將玉米轉換為能源的途徑,積極賺能源的錢。

由於玉米能源生產的方式預計兩年內之利潤可超過100%,多方人馬也覷覦這塊大餅。除農民的合作社組織外,其他投資者、平衡基金及如比爾蓋茲之流者也都積極參與這一行列。預計在年底前有卅九座提煉廠興建,其生產量每年可達46億加侖的乙醇代用汽油,比今年增產30%。預計2008年可達八十億加侖,但這一數量約僅能取代3%的石油用量,或者一天約160萬桶的原油量。

The Mk4 Stirling Engine

這是 Mk4 史特林引擎

TheStirling engine - built from Maccano, various tin cans, and two graphite pistons running inside glass cylinders, sleeved in black plastic. Stirling as in Stirling engine is spelt Stirling not Sterling. For the technically minded, the displacer is 6cm diameter by 2.5cm stroke, and the piston is 1.6 cm diameter by 4cm stroke. The displacer is in an air tight chamber and is moved up and down, by a thin wire passing through a seal made of silicone bathroom sealant. This moves 'displaces' a trapped volume of air from the 'hot end' heated by a tea light candle and the 'cold end' which is at room temperature, this causes the air to expand and contract, pulling and pushing on the piston, driving the engine. The Flexi springs are made using a new type of ultra thin springy strip that Meccano new include in some of their sets. The Video was taken in wide screen format - don't know how to get wide screen to play properly in Google video. This is all part of my main hobby which is promoting alternative energy. Check out www.westmill.coop which is a community owned wind farm I'm involved in.

Nikola Tesla 發電機之父

特斯拉發明交流電發電機及感應馬達。是近代電工機械發明之始祖。

Nikola Tesla is considered the father of our modern technological age. This program reveals the discoveries of a forgotten genius, many of which went unnoticed for nearly a century. How did this obscure visionary from what is now Yugoslavia lay the foundation for modern communication and which of his inventions were considered a little too revolutionary by government agencies and the power brokers of the time. Among his discoveries are: fluorescent light, the laser beam, wireless communications, wireless transmission of electrical energy, remote control, robotics, Tesla?s turbines and vertical take off aircraft. Tesla is the father of the radio and the modern electrical transmission system. Tesla registered over 700 patents worldwide. His vision included power from the sea, exploration of solar energy, the discovery of cosmic radio waves, and the use of the ionosphere for scientific purposes. He foresaw interplanetary communications and satellites.

Encore’s proof-of-concept SideWinder wind-turbine demo unit develops tremendous torque at its central shaft even in low speed winds. The SideWinder is radically-different than any other wind turbine technology being offered today and targets the most lucrative and currently untapped market for wind power: the low wind-speed ROOFTOP WIND market -- harnessing clean wind energy on top of mini-malls and buildings around the world. As of yet, we don’t have every aspect of the system optimized (we still need to engineer a soft-landing pneumatic or hydraulic shock-absorber system for the wind-shutters/louvers when they open). The shutters/louvers are made out of high-strength low-weight carbon composites and right now, because of the varying wind speeds and wind gusts that will change the RPM of the power take-off shaft -- we plan to connect the SideWinder’s central rotating mast with gears to a DC generator whose DC output is then sent through a high-power DC-AC inverter to give the end-user the AC power it needs.

樹木採收機

Description:
Conventional forest machines are expensive and can normally, do only one type of job. The excavator based harvester is a multi-functional and economical alternative for harvesting purposes. The fitting of harvester heads to excavator bases is standard practice throughout forestry. These machines are quite often just as sophisticated and capable as purpose built machines, but cost only a fraction of the price. AFM-Forest Ltd has developed special harvester heads for excavators. They adapt very well on excavators because of both their diversified hydraulic-steering system and a strong and also simple body structure. The frame of AFM heads is executed from high-strength steel, and as against heads of other manufacturers, it is monolithic which makes it highly durable and suitable for rough work on track based machines and excavators. AFM harvester heads can be easily installed on a modern track-based hydraulic excavator between 10-40 tons weight with some modifications and extra protections for forest use. AFM is a well proven solution for easy and inexpensive transformation of your excavator into an efficient harvester or processor.

能源與氣候

地球溫室效應升高,如何應付是當前各國重要的共同課題。二氧化碳及甲烷等之含量增高,均必須採取適當措施加以控制,目前地球暖化約華氏十度 ,海洋中之二氧化碳濃度也增高,對生態之影響也十分巨大。本影片有兩個主講者,開始由史丹福大學歐爾教授(Franklin M. (Lynn) Orr, Jr)主講地球環境之變遷。其中介紹奈米光電池之利用、引擎之改良、儲存二氧化碳及生物氫等等都是可行的方案。
另一主講者為洛姆先生(Joseph J. Romm),其主題為氫能之應用。他特別強調氫能要取代現在之石化原料,不太可能。氫的成本特高,其儲存不易。其主要應用問題包括:氫能車價格高、燃料費用高,空間小彈性小、燃料彈性小、安全性、不太環保且可能至少要到2025年才有機會出現商品化車。

2005生歐盟物燃油產量大幅上升

根據歐洲生物燃料油理事會 (European Biodiesel Board, EBB)發佈的資料,2005年歐盟國家生物燃料油的產量已大幅上升,並成為全球生產生物燃油最多的地區。去年歐盟共生產3,184,000噸生物燃料油,較前年增加65%。美國生物燃料油的年生產量約為250,000噸。與石化燃料相比仍然杯水車薪,但為減少對石油的依賴及環保上的需求,這些努力仍值得肯定。歐盟近年來極力推動從植物油中提煉生物燃料油,供汽車使用。預計2010年可生產生物燃料油達到全球燃料油產量的5.75% ,屆時將會有顯著的替代效果。在歐盟二十個已生產生物燃料油的會員國中,去年以德國為1,600,000噸,比例最高,法國492,000噸次之,義大利為396,000噸 ,名列第三。
