Heat is an abundant but often wasted source of energy. Thus, harvesting just a portion of this
tremendous amount of energy holds significant promise for a more sustainable society …

Summary Low-grade heat (< 100° C) is abundant and ubiquitous but is generally discarded
owing to a lack of cost-effective recovery technologies. Emerging liquid-state thermocells …

Low-grade heat (below 373 kelvin) is abundant and ubiquitous but is mostly wasted
because present recovery technologies are not cost-effective. The liquid-state thermocell …

High-performance thermogalvanic cells have the potential to convert thermal energy into
electricity, but their effectiveness is limited by the low concentration difference of redox ions …

Harvesting heat from the environment into electricity has the potential to power Internet-of-
things (IoT) sensors, freeing them from cables or batteries and thus making them especially …

Solar vapour generation is an efficient way of harvesting solar energy for the purification of
polluted or saline water. However, water evaporation suffers from either inefficient utilization …

Solar desalination is an effective way of converting solar energy to heat for seawater
purification. The structure of absorbers and salt resistance are two crucial parameters for …

Thermocells hold great potential for continually harvesting waste heat to power ubiquitous
electronics, but their integration is hampered by leakage risk and poor mechanical …

Thermal energy, constituting the majority of the energy lost through various inefficiencies, is
abundant and ubiquitous. With thermogalvanic effect, thermocells (TECs) can directly …

Abundant and ubiquitous thermal heat called low-grade heat (< 150° C) is wasted in our
surroundings owing to the lack of effective and low-cost energy technologies. Thermo …
