Dubai makes its own RAIN to tackle 122F heat: Drones blast clouds with electrical charge to produce

Posted by in categories: business, drones, energy


Dubai uses drones to electrically charge clouds, causing tortential rains in one of the driest nations on Earth. Until now, such experiments had been done succeessfully from the ground only.

New molten salt battery for grid-scale storage runs at low temp and cost

Posted by in categories: energy, sustainability

As renewable forms of power like wind and solar continue to gain prominence, there will be a need for creative solutions when it comes to storing energy from sources that are intermittent by nature. One potential solution is known as a molten salt battery, which offers advantages that lithium batteries do not, but have their share of kinks to iron out, too. Scientists at Sandia National Laboratories have come up with a new design that addresses a number of these shortcomings, and demonstrated a working molten salt battery that can be constructed far more cheaply, while storing more energy, than currently available versions.

Storing vast amounts of energy in a cheap and efficient manner is the name of the game when it comes to powering whole cities with renewable energy, and despite its many strengths, this is where expensive lithium battery technology falls short. Molten salt batteries shape as a more cost-effective solution, which use electrodes kept in a molten state with the help of high temperatures. This is something that the Sandia scientists have been working to change.

“We’ve been working to bring the operating temperature of molten sodium batteries down as low as physically possible,” says Leo Small, the lead researcher on the project. “There’s a whole cascading cost savings that comes along with lowering the battery temperature. You can use less expensive materials. The batteries need less insulation and the wiring that connects all the batteries can be a lot thinner.”

Tesla Launches Megapack Order Page & Pricing

Posted by in categories: energy, sustainability

According to the order page, the price in California starts at $1235, 890, and Tesla requires $5000 down. This doesn’t include taxes or annual maintenance. Prices do vary by state. Customers can order up to 1000 Megapacks, and if they do, the costs per unit decline with each additional Megapack order.

On its website, Tesla said that it took everything it knew about battery technology to enable the world’s largest energy projects. For these giga-scale projects, a 1 gigawatt-hour (GWh) project provides enough energy storage capacity to power every home in San Francisco for 6 hours.

For those ordering the Tesla Megapack, the earliest deliveries will occur in 2022, but not for all states. California, Nevada, and Texas have 2022 delivery estimates, while others, including my own state of Louisiana, have 2023 estimated delivery dates. The price of the Megapack for Louisiana is $1252, 810.

Fossil fuel electricity generation has peaked worldwide

Posted by in categories: economics, energy, finance

“Emerging markets have no need to build up huge electrical infrastructure based on fossil fuels. Instead, they are leapfrogging this stage and meeting growth in demand by deploying clean energy systems — such as wind and solar — with huge potential to boost economic development and bring electricity to millions more people.”

Fossil fuel electricity generation has peaked worldwide as emerging markets seize the opportunities of low-cost renewables, according to a report published this week by India’s Council on Energy, Environment and Water (CEEW) and the financial think tank Carbon Tracker.

Renewables are already the cheapest source of new electricity additions in 90% of the world, the report notes. Emerging markets (non-OECD nations plus Chile, Colombia, Mexico and Costa Rica) therefore have no need to build up huge electrical infrastructure based on fossil fuels. Instead, they are leapfrogging this stage and meeting growth in demand by deploying clean energy systems – such as wind and solar – with huge potential to boost economic development and bring electricity to millions more people.

New wearable device uses human sweat to power electronics

Posted by in categories: energy, space, wearables

Engineers at the University of California San Diego developed a new wearable device that turns the touch of a finger into a source of power for small electronics and sensors. The device is a thin, flexible strip worn on a fingertip and generates small amounts of electricity when a person’s finger sweats or presses on it.

More interestingly, this sweat-powered device is capable of generating power even when the wearer is asleep or sitting still. This could open up some very interesting possibilities in the wearable space, as the researchers have now figured out how to harness the energy that can be extracted from human sweat even when a person is not moving.
