A low-angle, wide-lens street shot in a bustling cityscape (similar to Shibuya, Tokyo). A young woman crouches confidently beside a modified, glossy purple sports car with a Japanese license plate. She wears a black graphic tee, cargo pants, white sneakers, and silver jewelry. The background features tall glass skyscrapers, colorful billboards, neon signage, and warm late-afternoon lighting. Strong perspective distortion emphasizes the height of the buildings and the car’s aggressive stance. The mood is stylish, bold, and modern, capturing urban automotive culture with a cinematic, hyper-real aesthetic. High detail, high contrast, crisp reflections, editorial fashion vibe, dynamic street energy.
A close-up of a young man (as in the uploaded image) Dominates the right side of the frame, viewed from a low-angle perspective, giving him a powerful and imposing presence. He is wearing a simple white tank top (muscle shirt) and tan or light-yellow cargo shorts. He is holding a wooden baseball bat slung over his right shoulder. His expression is serious and determined.

JustinE the Rottweiler: Located on the left, chained to man. JustinE is in an aggressive stance, mouth wide open in a fierce snarl or bark, showing his teeth and tongue, with saliva visible. He is wearing a thick, heavy silver chain leash and collar, with a small circular dog tag visible that says "JustinE". The dog is large and muscular, facing the viewer.

Leash: A heavy-gauge silver metal chain connects JustinE's collar to man's hand.

Lighting: Strong, harsh daylight typical of Southern California, creating deep shadows and high contrast, enhancing the dramatic feel.

Background/Setting: A Southern San Andreas (Los Santos) street setting. The background is slightly blurred but suggests a hot, dry, urban environment with power lines/telegraph wires and a glimpse of an older vehicle (possibly a green van) in the lower-left corner. The sky is a bright, clear, light yellow-green color, indicative of a hot day.

hard shadows, and a distinct color palette typical of GTA loading screens and cover.

Highly detailed and rendered. Vibrant, cinematic.
Highly detailed, artistic illustration of two cats sitting together on the bustling Nathan Road in Hong Kong. One cat is a sleek black feline with emerald green eyes, the other is a fluffy ginger tabby with white paws. They are perched near the neon-lit storefronts and glowing billboards, surrounded by vibrant city life: crowds of people, bright taxis, and street vendors selling local food. The scene is alive with colorful reflections on rain-slicked pavement, atmospheric mist, and dramatic lighting from neon signs in Chinese characters. The artistry should blend urban realism with a touch of whimsical charm, focusing on the cats' expressive faces and the dynamic ambiance of Nathan Road at night.

Google計劃於2027年發射配備TPU AI晶片的衛星

Google今日公布了「Project Suncatcher」計劃,準備將人工智能晶片送入太空,搭載於衛星上運作。

這個計劃的主要動力來自太空中太陽能板的高效能發電能力,遠超地球上的太陽能板,而且不需要電池作備用。地球上的太陽能板需要電池在夜晚或下雨時提供備用電力,但在太空中,太陽能板可以持續發電,無需依賴電池。

Google相信,太空太陽能板帶來的效率提升,最終能抵銷將晶片送上太空的高昂成本。Google的智能研究部門高級總監Travis Beals在一篇博客文章中指出:「太空數據中心的發射和運營成本,可能會與同等規模的地面數據中心在每千瓦/年的能源成本相當。」

然而,運行軌道上的AI集群有挑戰,因為語言模型通常需要多張圖形處理器協同運作,這些圖形卡分別安裝在不同衛星上,必須有效交換數據。

Google計劃利用自由空間光通信(FSO)技術,通過激光束編碼網絡流量來同步衛星間的信息。問題是,Google提議的FSO系統需要達到每秒數十太比特的數據傳輸率,這比現有FSO系統的功率需求高出數千倍。

為了降低功率需求,Google打算將衛星部署得彼此非常接近。衛星間距越短,傳輸數據所需的功率就越低。但這也帶來了新的挑戰:衛星靠得太近,必須防止碰撞或偏離軌道。

為此,Google開發了一套物理演算法,模擬密集衛星星座的運作,結果顯示這些挑戰是可控的。Beals表示:「模型顯示,只要衛星相距數百米,我們只需進行少量軌道維持操作,就能在預定的太陽同步軌道上保持穩定。」

此外,Google還評估了AI晶片在太空輻射環境下的耐受性,重點測試了最新一代TPU機器學習加速器「Trillium」。結果顯示,即使是Trillium中最敏感的高帶寬記憶體(HBM)也能在軌道上安全運行多年。

據Semafor報導,Google計劃於2027年與公開上市的衛星營運商Planet Labs PBC合作,發射首批兩顆配備TPU的衛星。Google預計,太空AI集群在2035年左右將具備經濟可行性。

編輯評論:

Google這個「Project Suncatcher」計劃,標誌著AI運算和太空科技的結合邁出重要一步。將AI晶片送入太空,利用高效率的太陽能發電,不僅可能改變未來數據中心的能源使用模式,更有望解決地面數據中心面臨的能耗和環境問題。

然而,這項計劃的挑戰極大,尤其是衛星間高速數據傳輸的技術實現,和在狹小空間內保持衛星穩定運行的軌道控制,都是前所未有的難題。Google在物理模型和輻射測試上的突破,顯示他們在這方面已做足準備,但實際的運行效果仍需時間驗證。

另外,這也反映了未來AI硬件發展的方向——不只是提升性能,更是尋求更環保、更可持續的運算平台。隨著地球資源日益緊張,太空成為新的「數據中心戰場」已非天方夜譚。

最後,Google此舉也會對衛星通訊、AI雲端服務和全球網絡架構帶來深遠影響。若能成功推進,未來我們可能見證一個結合太空能源與人工智能的全新生態系統,真正實現「AI上天」的願景。這不僅是科技的進步,更是對未來能源和計算模式的革命性思考。
