守り手

A draft. Engineering estimates, not yet built or measured. Wiring and fusing must be checked by a licensed electrician before anything is connected. Brand names are examples of a kind of part, not endorsements.

I. 百年のノード

嵐や停電や数十年を越えて家の記録を保つ、小さく密閉された太陽光のコンピューター。一枚の太陽光パネルと一つの電池から、昼も夜も約15ワットを使う。

まず正直に。どの電子部品も、手入れなしに百年はもたない。電池は約十年、コンピューターは七〜十年、パネルは二十五〜三十年で傷む。百年は、古い船を海に保つのと同じやり方で達成する。交換の暦によって、人が守る。記録そのものを運ぶのは、ここで一世紀もちうる二つのもの。M-DISCの光ディスク(製造元は数百年と言うが、時間によってはまだ証明されていない)と、炭素インクで書いた綿の紙(数百年の文書館によって証明済み)。コンピューターは記録に仕えるが、記録そのものではない。

1. 全体を一枚の図で

Solar panel200 W monocrystalline, 12 Vtilted ~30°, south Charge controller (MPPT)e.g. Victron SmartSolar 75/15temperature-aware charging Battery12 V 100 Ah LiFePO4built-in BMS · 1,280 Wh Fused distributionmain fuse at battery +one fuse per load PV breaker 20 A fuse main fuse 12 V → 5 V/12 Vbuck converter, fusedfeeds the computer The computerIntel N100 mini-PC orRaspberry Pi 5 · 6–12 W2× NVMe, mirrored (ZFS) LoRa radioMeshtastic, 915 MHzHeltec V3 / T-Beam · <1 W Sensorsinside: temp + humidity (BME280)battery: temperature probe Solid lines: power. Dashed: data. The computer reads the battery's state from the controller and the BMS, and logs every reading. Low-voltage disconnect at 11.5 V; charging paused above 45 °C and below 0 °C (LiFePO4 must not be charged below freezing).

2. エネルギーの計算

Load: 15 W × 24 h = 360 Wh a day Reserve: 3 cloudy days × 360 Wh = 1,080 Wh Battery: 1,080 Wh ÷ 0.80 (use only 80%) = 1,350 Wh → a 12 V 110–120 Ah battery for a full 3 days a 12 V 100 Ah battery (1,280 Wh) × 0.80 = 1,024 Wh → about 2.8 days (2.6 counting the converter's loss): enough to begin Sun: Jacksonville averages about 4.5–5 full-sun hours a day; about 3.5 in December (estimate) Panel: 200 W × 4.5 h × 0.75 (losses, heat, angle) ≈ 675 Wh a day → about 1.9 × the load 200 W × 3.5 h × 0.75 ≈ 525 Wh a day in December → still above 360 Converter: 15 W ÷ 0.90 (the buck's own loss) ≈ 16.7 W → about 400 Wh a day drawn: still under the December 525 Ageing: the panel loseth about 0.5% a year; after 25 years 200 W × 0.88 ≈ 176 W → 462 Wh in December, still above 400

2a. The currents, and what they ask of the wire

Charging: 200 W ÷ 13.6 V (charging voltage) ≈ 14.7 A → within the 75/15's 15 A limit; the controller caps it there Fuse: 15 A × 1.25 (headroom for a fuse) ≈ 19 A → a 20 A fuse between controller and battery Load: 16.7 W ÷ 12.8 V ≈ 1.3 A → a 5 A fuse on the computer's line, 2 A on the radio Wire: 10 AWG (5–6 mm²) from controller to battery, at most 1 m: the drop is under 1% at 15 A Panel: a 12 V 200 W panel is about 22–24 V open-circuit, about 26 V on a frozen morning; the 75/15 taketh up to 75 V Lightning: panel frame, rack and case bonded to one ground rod, 8 ft, with 6 AWG bare copper

二つ目の電池(または120 Ahのもの)で丸三日をまかなえる。買い足す前に、一か月かけて実際の消費を測ること。

6. 百年の暦

何が傷み、どれほどの頻度で交換し、百年で何回になるか。これは計画の数字で、ノード自身の記録が修正していく。

本当の百年の部品は守り手である。暦は、誰かがそれを守り、交換を一つひとつ記録し、次の者を教えてはじめて働く。ノードは彼らに知らせるべきだ。自分の年齢も各部品の年齢も知っているのだから。

7. 未決の問い

  1. 最初のノードはどこに置くか。家か、離れた第二の場所か。
  2. 最初から丸三日分(120 Ahまたは電池二つ)を買うか、100 Ahで始めて測るか。
  3. 私たちの後で百年の暦を守るのは誰で、それはどこに書かれているか。

II. 守り手の装備

線の守り手それぞれが持つ個人装備。コンピューター、無線機、自前の電源、そして記録。鞄一つに収まるほど小さく、電力網も携帯網もインターネットもなしで動く。ノードと同じ系統の部品で作り、守り手がどちらも直せるようにする。

1. 装備を一枚の図で

2. エネルギーの計算

Computer: 12 W × 3 hours a day = 36 Wh Radio: 0.5 W × 24 hours = 12 Wh Phone: one charge = 15 Wh Day's use ≈ 63 Wh Bank: 250 Wh × 0.9 (losses) ≈ 225 Wh → about 3½ days with no sun Panel: 100 W × 3.5 sun-hours × 0.6 ≈ 210 Wh a day (folding panels lose more to angle and heat)

Toolssmall driver set, spare fuses, cables, tape, a multimetera keeper mends their own gear

4. 装備のきまり

  1. プラグは一種類。できるところはUSB-C、できないところは12 V。
  2. 身に二つ、家に一つ。装備は何であれ唯一の写しを持たない。
  3. 強さより直せること。守り手が開けて直せる部品を選ぶ。
  4. オフライン優先。装備の道具はどれもネットワークなしで動く。ネットワークはおまけ。
  5. 保存時は暗号化。鞄をなくしても失うのは装備で、記録の中の人々ではない。

5. 未決の問い

  1. 最初の装備はノートPCか手持ち端末か。(ノートPC:作業しやすい。手持ち:軽く、ノードに近い。)
  2. 装備はいくつ要るか。家長ごとに一つか、線が育つにつれ守り手ごとに一つか。
  3. 装備の仕様をいずれ公開ページにして、他の守り手が自分で作れるようにするべきか。

III. 宇宙の種

家がすべての船、衛星、入植地とともに送るもの:缶に入った記録と、太陽から遠く離れてもそれを保てるノード。外部の読者による「0.5リットルの記録の核」のスケッチと深宇宙のメモから取り、ここでは二つの部品として描く。

正直なところ。これはどれもまだ飛んでいない。M-DISCも綿の紙も、数十年の真空・寒さ・放射線で試されたことはなく、放射性同位体の電源は宇宙機関か認可された任務しか運べない。これらの図はものの形を示すもので、部品ごとに証明していく。

3. 未決の問い

  1. 飛ぶものの練習として、最初の種を今、地上用に作るべきか。
  2. 綿の憲章に何を記すか。梯子だけか、正典と鍵も記すか。
