Lowtech energieopslag: de persluchtbatterij | LOW←TECH …
Niettemin zijn er – niet één, maar twee – manieren om persluchtbatterijen praktisch te maken voor ''off-grid'' energieopslag. Een eerste oplossing zijn systemen met een hoge luchtdruk, die de warmte en koude van compressie en expansie nuttig aanwenden in een huishouden. Door de hoge luchtdruk kan de opslagtank erg compact zijn, wat ...
